TY - JOUR TI - Development of seersucker fabrics using single warp beam and modelling of their stretch-recovery behaviour AU - Maqsood, M. AU - Nawab, Y. AU - Usman Javaid, M. AU - Shaker, K. AU - Umair, M. T2 - Journal of the Textile Institute AB - Seersucker is a thin and puckered fabric used to make clothing for spring. Due to its specific structure, this fabric is held away from the skin when worn, facilitating heat dissipation and air circulation. Seersucker is produced by slack tension weaving using two warp beams. Due to the use of two beams, such fabrics were not possible to weave on conventional (with single warp beam) weaving machines. Additional twin beams arrangement was required for such weaving. The objective of the current study is to produce seersucker fabric on conventional looms using a single warp beam. For achieving this objective, two types of weft yarn: 100% cotton yarns and blended yarns of cotton and elastane (95.67% cotton and 4.33% Lycra) are used in groups. The viscoelastic behaviour of the produced fabric samples is tested using ASTM standard D3107-07. Instant deformation, elastic recovery, creep and relaxation were recorded and plotted as function of Lycra % age.

T2 - Journal of the Textile Institute AB - The aim of this study was to develop statistical models for the prediction of warp and weft crimp percentage of cotton woven fabrics. The developed models are based on the empirical data obtained from carefully developed 60 fabric samples with different yarn linear densities, fabric densities, and weave designs. The predictability and accuracy of the developed models was assessed by correlation analysis of the predicted and actual crimp values of another set of eight fabric samples which was not used for the development of models. The results show fairly good capability and accuracy of the prediction models.

AU - Nawab, Y. AU - Ashraf, M. AU - Shaker, K. AB - For manufacturing of long life and sustainable materials, self-healing composites are an emerging concept. Mixing of resin with microcapsules containing healing agent is the best way to achieve this purpose. Curing of composites during thermal cycle leads to rise in temperature at core due to entrapment of heat of reaction and it may cause degradation of mixed capsules. In the present work thermal stability of microcapsules during fabrication of unidirectional thermoset carbon/epoxy self-healing composite is studied. For this purpose heat transfer coupled with cure kinetics and structural mechanics equation are solved using finite element methods. Analysis of samples, having thickness in the range 2mm-60mm, provides the information if capsules in the composite degrade as well as the quantity of degraded capsules.

AU - Nawab, Y. AU - Javaid, M.U. AU - Umair, M. AU - Maqsood, M. T2 - Autex Research Journal AB - Abstract This paper introduces a 3D woven fabric-based approach for the development of pressure switch. A fabric substrate, being elastic and extendable is very useful in addition to its high breaking strength and low cost. The developed resistive-type switch is based on the multilayer interlock 3D fabrics. In the top and bottom layers, certain number of conductive yarns are woven separated by cotton yarns in both transversal and thickness direction. Application of pressure makes the layers of conductive yarn to come in contact, resulting in a short circuit, which may be recorded using multi-meters. Removing the pressure cause the connection points to separate away and it depends on the weave design. Such switch can be used as an on/off switch for usage in security systems, can be sewn into carpets and wearable garments for a number of purposes.

AU - Nawab, Y. AU - Malik, M.H. AU - Shaker, K. T2 - Journal of Reinforced Plastics and Composites AB - Three-dimensional multilayer woven preforms are mostly used in high-performance composite applications due to their better in-plane and out-of-plane mechanical properties. The present study aims to produce and characterize multilayer flax yarn-based three-dimensional-shaped preforms and their corresponding composites. The T- and H-shaped three-dimensional woven preforms were prepared on conventional dobby loom using two types of weaving pattern, i.e., layer-to-layer orthogonal and through thickness orthogonal. Composites were fabricated using open mould technique. Peel strength of T- and H-shaped structures was investigated and compared with laminated structures. Mechanical properties of layer-to-layer-interlocked structures in T and H shapes were found better than TT and laminated structure, both for reinforcement and composite.

AU - Saouab, A. AU - Nawab, Y. T2 - Composites Part A: Applied Science and Manufacturing AB - In this article, numerical simulation of suspension (particles filled-resin) flow through a fibrous media taking into account dual scale porosity in LCM (Liquid Composite Molding) processes is presented. During the flow, a strong interaction between the particle motion and the fluid flow takes place at the porous media wall (the fiber bundle surface). In this study, the Stokes–Darcy coupling is used to describe the resin flow at mesoscopic scale to treat the particles in suspension. A “fluid” model to describe the suspension flow, a “filtration” model to describe the particle capture and a “solid” model dedicated to the modeling of mass particles dynamics was used. The “solid” model is also operated to identify the particles retention. For validation, the numerical results of proposed model were compared with the experimental results from the literature and found in good agreement. Then, other numerical results studying the suspension’s rheological behavior are presented.

Its Modelling is a coupled multiphysics phenomena. Precise information about the chemical shrinkage, thermal expansion coefficient, cure kinetics, heat transfer and constitutive equation are required for an accurate simulation. In this article, spring-in angle induced in woven carbon/epoxy composite bracket is modelled by solving the thermo-kinetics and thermo-mechanics coupling simultaneously in a commercial finite element software. The obtained values of spring-in angle using numerical simulation are compared with those found in the literature and both are found in agreement.

AU - Casari, P. AU - Boyard, N. AU - Sobotka, V. AU - Jacquemin, F. T2 - Journal of Reinforced Plastics and Composites AB - Cure shrinkage in the thermoset matrix is the major source of cure-induced defects in composite parts for industrial applications. Thus, its correct determination is very important to optimize the composite fabrication process. In general, volume chemical shrinkage of resin is tested and assuming it is isotropic, rule of mixture or a homogenization technique is used to model the linear chemical shrinkage of composite. Some studies are also found in the literature on the measurement of linear chemical shrinkage of very small composite samples under atmospheric pressure. In the present article, a new setup is presented for the measurement of evolution of in-plane chemical shrinkage of thermoset laminated composite during curing. Using this setup, characterization of mass scale samples was done under pressure and heating ramp conditions. Degree of cure of composite during the test was determined using differential scanning calorimeter. Results show that chemical shrinkage in the composite appears from gel point and its evolution with the degree of cure is nonlinear. Experimental results also led to conclusion that most of the chemical shrinkage occur along the thickness direction.

T2 - Journal of Reinforced Plastics and Composites AB - This study was aimed to investigate the effect of fluorocarbon, hydrocarbon, and hybrid fluorocarbon on the mechanical properties and moisture regain of jute fiber reinforced composite materials. A significant difference in moisture regain values of treated and untreated reinforcement samples was observed, when the concentration of chemical finish (hybrid fluorocarbs) was 40 g/L. The composite made from treated reinforcement regained very low moisture content as well as exhibited improved mechanical properties (tensile and flexural strength). Having both characteristics (hydrophilic and hydrophobic groups) in hybrid fluorocarbon, the treated jute fibers and corresponding composites showed better properties as compared to counterparts treated by other two chemicals, due to better interface.

Weft-wise crimp controls the fabric width and it depends on a number of factors, including warp tension, temple type, fabric take-up pressing tension and loom working width. The aim of this study is to investigate the effect of these parameters on the fabric width produced. Taguchi’s orthogonal design was used to optimise the weaving parameters for obtaining controlled fabric width. On the basis of signal to noise ratios, it could be concluded that controlled fabric width could be produced using medium temple type and intense take-up pressing tension at relatively lower warp tension and smaller loom working width. The analysis of variance revealed that temple needle size was the most significant factor affecting the fabric width, followed by loom working width and warp tension, whereas take-up pressing tension was least significant of all the factors investigated in the study.

Fabric samples of areal densities ranging from 310-495 g/m2 were knitted using yarns of three different cotton/polyester blends, each of two different linear densities by systematically varying knitting loop lengths for achieving different cover factors. It was found that by changing the polyester content in the inner and outer fabric layer from 40 to 65% in the double layer knitted fabric has statistically significant effect on the fabric thermal resistance. Fabric thermal resistance increased with increase in relative specific heat of outer fabric layer, yarn linear density, loop length, and fabric thickness while decrease in fabric areal density. It was concluded that response surface regression modelling could be successfully used for the prediction of thermal resistance of double layer interlock knitted fabrics. The model was validated by unseen data set and it was found that the actual and predicted values were in good agreement with each other with less than 10% absolute error. Sensitivity analysis was also performed to find out the relative contribution of each input parameter on the air permeability of the double layer interlock knitted fabrics.

T2 - Polymer Composites AB - Sandwich composites based on coir fiber nonwoven mats as core material were manufactured by Vacuum Assisted Resin Transfer Molding technique. Mechanical and physical properties of produced coir/polyester and coir‐glass/polyester composites were assessed. Samples were evaluated according to their reinforcement contents, resin contents, areal density, and thickness. Tests on physical properties revealed that coir‐glass/polyester sandwich structure has the lowest values of thickness swelling, water absorption and moisture contents compared with coir/polyester composite. Mechanical tests such as tensile strength, open‐hole tensile strength, and flexural strength were also performed on all samples. Coir‐glass/polyester sandwich structure showed significant increase in tensile strength of 70 MPa compared with 8 MPa of coir/polyester composite. Introducing two skins of fiber glass woven roving to coir/polyester increased its flexural strength from 31.8 to 131.8 MPa for coir‐glass/polyester. POLYM.

An online survey methodology including open- and closed-ended questions was implemented. A convenience sample of 442 responses was obtained from one US Midwestern institution and used for data analyses. The results of content analysis showed that Gen Y had a lack of knowledge regarding apparel with CSR attributes, specifically those pertaining to fair-trade products. The results of independent samples’ t-test and multiple linear regressions confirmed positive significant effects of moral obligation on purchase intentions, with females having significantly higher levels of moral obligation and attitudes towards purchasing apparel products made of organic materials, fair-trade label, and recycled materials. Findings provide insights into Gen Y as ethical consumers that can lead to future growth of CSR promotions in the apparel industry.

T2 - Fashion and Textiles AB - Abstract Given keen national interest in the fashion sense of First Lady Michelle Obama, few studies have examined the appeal of the first lady’s style and if her example influences women to modify their styles and shopping behaviors. To address this paucity in the research, the purpose of this study was to explore the impact of Michelle Obama’s apparel choices on women. To address this purpose, ten semi-structured interviews were conducted with women who follow Michelle Obama’s fashion and rated her style as appealing. Qualitative analysis of the interviews revealed three themes: (1) relating through authenticity, (2) permission to defy norms, and (3) brands and the impression of endorsement. Findings reveal that Michelle Obama’s apparel choices make her relatable to everyday women. Participants noted that the first lady’s fashion choices gave them permission to challenge fashion norms for women, and adjust their personal styles. Lastly, several retail brands were thought of more positively by participants, given Michelle Obama’s implied endorsement.

To effectively use IJDTP, users must possess skills in computer-aided design (CAD), colour control, and print design. To address impediments to effective implementation of IJDTP, a study was conducted that assessed the user skill level of crafters, designers, artist/artisans and small business owners/entrepreneurs. Data were collected from an international user base of a US print-on-demand IJDTP company to address the study's objectives (N = 624). The majority of participants self-identified as crafters (47%) and self-reported below average skills in CAD, colour control and creating repeat patterns. Significant differences emerged between the four user types and their skill levels. The study's results inform both educators and practitioners who use IJDTP and who require adequate skills to implement this emergent technology.

AU - Xu, Y. AU - Thomas, J. T2 - Journal of Fashion Marketing and Management AB - Purpose – The purpose of this paper is to investigate Generation Y consumers’ luxury fashion consumption. Generation Y is becoming a very important segment for the luxury market in the USA. Specifically, this study is designed to investigate Generation Y consumers’ consumption of luxury fashion products from the following perspectives: the influence of self-related personality traits on their brand consciousness; and the influence of brand consciousness on consumption behaviours in terms of consumption motivations, purchase intention, and brand loyalty. Design/methodology/approach – A conceptual model was developed to represent the proposed relationships among the related variables. An online survey was conducted and 305 valid surveys were collected. The proposed hypotheses were tested using structural equation modelling (SEM) analyses. Findings – From the perspective of self-concept, this research shed some light on the luxury fashion consumption behaviour of Generation Y consumers. Public self-consciousness and self-esteem were both found having significant influence on Generation Y consumers’ brand consciousness and in turn their luxury consumption motivations and brand loyalty. Research limitations/implications – Limitations for this study mainly come from the representativeness of the sample, which was recruited from a panel of a third party research group. Implications for luxury fashion brand managers and retailers focus on strategies that influence the social and self-motivation for luxury consumption and level of brand consciousness. Originality/value – This research is unique because it focuses on luxury fashion consumption of Generation Y consumers, an emerging segment in the luxury market. Generation Y consumers’ behaviour towards luxury fashion was examined in terms of their self-related personality traits, brand consciousness, motivation, and brand loyalty.

AU - Xu, Y. T2 - Journal of Product & Brand Management AB - Purpose – This study aims to investigate Chinese young consumers’ brand loyalty toward sportswear products from a self-congruity perspective. With different performance observed between global and domestic sportswear brands in the Chinese market, this study also aims to examine the impact of country of origin on Chinese young consumers’ behavior toward sportswear brands. Design/methodology/approach – A survey with street intercept method was conducted in Shanghai to collect data for this study. Multiple independent t -tests and structural equation modeling (SEM) with bootstrap method were used to test the hypotheses. Findings – The SEM results indicate a significant influence of brand self-congruity on consumers’ brand association and perceived quality, which, in turn, influenced consumers’ brand loyalty. The multiple t -test results suggest a significant difference between Chinese and global sportswear brands in terms of consumers’ brand association and attitudinal brand loyalty. No significant difference was found in terms of consumers’ behavioral brand loyalty. Research limitations/implications – The main limitation of this study comes from the convenience student sample. Practical implications – First, brands need to strategically design the brand image to represent the largest segment of the target market. Second, while global brands could focus on their pricing strategies, domestic brands need to focus more on maintaining a positive brand association in consumers’ mind. Originality/value – This study contributes to the growing research on the self-congruity perspective of brand loyalty by empirically confirming the indirect effect of brand self-congruity on brand loyalty via the mediation effects of brand association and perceived quality in the context of the ever-growing Chinese sportswear market.

An Experimental Analysis of Group Differences on Product Evaluations for Scarce and Brand-Presence Products AU - Childs, Michelle L. AU - Jin, Byoungho T2 - Journal of International Consumer Marketing AB - The desire for status is a strong motivational force that encourages consumers to appraise products/brands associated with high social standing. This research investigates two social status marketing techniques (scarcity and the presence of a brand) on product evaluations and tests whether particular characteristics (i.e., according to gender, cultural orientation, and consumers' desire for unique products) explain differences. Based on an experimental study conducted in the United States, evaluations are higher for social status marketing techniques. Females evaluate brand-presence products more highly, and consumers with a high desire for unique products evaluate scarce products more highly. This study assists marketers in developing a successful strategy to target specific consumer groups.

The Impact of Apparel Companies’ Corporate Social Responsibility Practices on Brand Equity AU - Woo, Hongjoo AU - Jin, Byoungho T2 - Clothing and Textiles Research Journal AB - Although Corporate Social Responsibility (CSR) is a crucial issue for the apparel industry, it was limitedly investigated whether consumers' perceptions of CSR affect apparel companies’ brand equity in previous research. The purpose of this study was (a) to examine the impact of apparel companies’ CSR on brand equity compared to the impact of apparel product attributes; (b) to compare the relative impact of different CSR activities (i.e., human rights, labor, social, environmental, product responsibility, and economic) in enhancing brand equity; and (c) to discover the moderating effect of culture on the influence of CSR on apparel brands’ equity. In testing the cultural moderating effect, the authors selected the United States and South Korea as countries representing opposite sides of Hofstede’s cultural values. The results of analyzing 447 survey data revealed that both intrinsic and extrinsic apparel product attributes significantly enhance brand equity. Among the six types of CSR activities, only the CSR practices for product responsibility, economic, and environmental issues were found to enhance brand equity. There was no moderating effect of culture. However, additional analyses revealed that the U.S. consumers evaluated the apparel brands’ CSR practices higher than do the Korean consumers. Findings of this study suggest implications for apparel companies, such as the relative importance of the specific CSR dimensions and apparel product attributes on brand equity, and if such relative importance of CSR dimensions varies across cultures.

AU - Jin, B. T2 - Journal of Service Theory and Practice AB - Purpose – Grounded in the Uppsala model, the purpose of this paper is to investigate specific firm factors of fashion service retailers, which include: product category offering, firm experience (limited vs extensive) and firm size (small vs large) and examines how variations in these firm characteristics produce significant differences on three aspects of internationalisation activities; scale and scope of internationalisation, market choice (geographic and cultural distance), and financial performance (international sales and profit), and whether market choice produces differences on financial performance. Design/methodology/approach – Secondary sources were utilised to empirically investigate retailers ( n =118). Information regarding product category offering, year of establishment, number of employees, countries entered, international sales, and profit were collected from retailer web sites, press releases, and annual reports. Findings – There were significant differences between product category offering and firm size in retailers’ internationalisation behaviours, and there were significant differences between product category offering and market choice in their financial performance. Variations in firm experience did not produce any significant differences. Research limitations/implications – This study extends limited literature on the internationalisation of fashion service retailers and contributes knowledge of how variations in specific firm factors produce different outcomes in terms of internationalisation, market choice, and financial performance. Practical implications – Retailers offering functional products may be more flexible in their internationalisation. Firms regardless of experience or size may consider being active in international markets because variations in these factors does not impact performance. Originality/value – This study addresses multiple gaps in retailer internationalisation literature and findings point that product category should be considered when studying internationalisation of service firms.

Testing Kano’s theory in four countries AU - Jin, B. AU - Bennur, S. T2 - Clothing & Textiles Research Journal AB - Built on Kano's theory of attractive quality, this study posits that apparel attributes contributing to customer satisfaction differ by a country’s economic development level since consumers’ expectations toward apparel products change. Analyses with data collected in four countries (India, China, Korea, and the U.S.) supported all hypotheses. That is, apparel attributes were classified into different Kano’s categories by country. Attributes classified as performance and attractive categories contributed to satisfaction more than the attributes classified in the other categories, regardless of country. Collectively, the findings suggest that as a country's economy advances, the role of brand is diminishing and attributes such as fashionability and versatility become more important in creating customer satisfaction. By discovering the life cycle of each attribute and tracing the path from developing countries to developed countries, this study provides an initial tool to predict how consumers' expectations toward an apparel product shift as a country advances economically.

T2 - Fashion & Textiles AB - Abstract The purpose of this study is to investigate U.S. small- and medium-sized apparel retailers’ international expansion by proposing a theoretical framework that incorporates the antecedents of small- and medium-sized apparel retail firms’ international market involvement. Data were collected via a self-administered questionnaire completed by apparel retailers nationwide. A total of 76 usable questionnaires were collected based on Dillman et al. (Internet, mail, and mixed-mode surveys: The tailored design method, 2009) Mail Survey technique. The results indicate that small- and medium-sized apparel retailers who have more foreign networks are likely to have foreign market knowledge. Firm age and market knowledge were found to influence a firm’s international market involvement. The results further reveal that market knowledge mediates the relationship between foreign networking and international market involvement. This study contributes to the growing knowledge base about small- and medium-sized retailers’ international expansion in the apparel industry.

To explain factors that influence landfill diversion rates for different types of products, an overview of the reverse logistics framework in the literature is provided. The framework is used to analyze the current state of carpet recycling in the USA, and PCC recycling is shown to be a typical material recovery network. Therefore, because PCC recycling requires a high volume of carpet to be collected and transportation costs to be minimized for it to be economical, a well-organized reverse logistics network is critical. In this respect, a review of reverse network design studies for different products is provided and research conducted to design PCC collection and recycling networks is discussed in detail.

AU - Bradford, Philip D. T2 - SMART MATERIALS AND STRUCTURES AB - Carbon nanotubes (CNTs) have a unique set of properties that may be useful in the production of next generation structural health monitoring composites. This research introduces a novel CNT based material system for strain and damage sensing applications. An aligned sheet of interconnected CNTs was drawn from a chemical vapor deposition grown CNT array and then bonded to the surface of glass fiber/epoxy composite coupons. Various types of mechanical tests were conducted, accompanied by real-time electrical data acquisition, in order to evaluate the electro-mechanical behavior of the developed sensing material. Specimens were loaded in the longitudinal and transverse CNT sheet orientations to investigate the anisotropy of the piezoresistive effect. The CNT sheets exhibited good sensing stability, linearity, sensitivity and repeatability within a practical strain range; which are crucial sensor features for health monitoring. It was also demonstrated that the CNT orientation in the sheet had a dramatic effect on the sensitivity, thus validating the usefulness of this sensing material for directional strain/damage monitoring. Finally, pre-straining of the CNT sheet sensors was conducted to further enhance the linearity of electro-mechanical response and long-term stability of the sensors during cyclic loading.

The goal of this study is to understand the effect of texture on color appearance in inkjet‐printed woven textiles. Cotton‐woven samples were constructed with nine different weave structures. Each sample was digitally printed with identical squares of primary colors cyan, magenta, and yellow and secondary colors red, green, and blue. The amount of ink applied was controlled consistently with an image editing software. CIE L* values were calculated from the measured reflectance. 25 observers ranked the perceived texture and color lightness of each sample. Perceived visual texture and perceived color lightness scales were estimated from the rankings using the rank order method. The measured CIE L* values and the scale of perceived lightness were positively related for the primary and secondary colors. Instrumental measurements of the textile surface characteristics were positively related to the visual scale. Texture was demonstrated to cause a measurable effect on color results in inkjet printing, both using instrumental and perceptual measures. To investigate if the color differences were substantial enough to cause “out of tolerance” ratings in textiles based on common textile industry color acceptance procedures, color differences among the samples were calculated and compared to a reference sample. Results demonstrated that color variation due to texture was sufficient to lead to rejection of a printed color in comparison to a color specification. © 2014 Wiley Periodicals, Inc.

AU - Hodgson, Thom J. AU - Kay, Michael G. AU - King, Russell E. AU - Thoney-Barletta, Kristin A. T2 - INTERNATIONAL JOURNAL OF PRODUCTION RESEARCH AB - The Economic Lot Scheduling Problem is a classical scheduling problem with the objective of minimising the long-run inventory and set-up costs of a single machine, multi-product inventory system. Demand rates, production rates and set-up times are assumed to be deterministic. The problem has been extensively studied and methods exist to obtain cyclic schedules which minimise total cost. In order to apply a cyclic schedule without a stock-out occurring, certain initial inventory levels are required. This paper considers the scenario where inventory levels are critically low and the cyclic schedule cannot be applied. Analytical methods are developed to determine: if the initial inventory is sufficient to prevent a stock-out from occurring; the maximum time until a stock-out will occur if a stock-out is unavoidable; and the minimum time required to obtain the necessary inventory to resume the cyclic schedule if a stock-out can be avoided.

However there is a huge controversy in the characterization techniques of ion beam irradiated or corona charged fibrous materials. In this study we reported a reliable, simple surface potential measurement method. Large variations in potential measurements were found to be mostly due to structural nonuniformity such as packing density, thickness and fiber–fiber proximity. Test samples were prepared after optimizing those parameters and we were able to reduce coefficient of variation below 15%. Methods that were developed so far were also reviewed.

AU - Curto, S. AU - Prakash, P. AU - Suh, M. AB - To overcome the limitations of currently available clinical hyperthermia systems which are based on rigid waveguide antennas, a wearable microwave hyperthermia system is presented. A light wearable system can improve patient comfort and be located in close proximity to the breast, thereby enhancing energy deposition and reducing power requirements. The objective of this work was to design and assess the feasibility of a conformal patch antenna element of an array system to be integrated into a wearable hyperthermia bra. The feasibility of implementing antennas with silver printed ink technology on flexible substrates was evaluated. A coupled electromagnetic-bioheat transfer solver and a hemispheric heterogeneous numerical breast phantom were used to design and optimize a 915 MHz patch antenna. The optimization goals were device miniaturization, operating bandwidth, enhanced energy deposition pattern in targets, and reduced Efield back radiation. The antenna performance was evaluated for devices incorporating a hemispheric conformal groundplane and a rectangular groundplane configuration. Simulated results indicated a stable -10 dB return loss bandwidth of 88 MHz for both the conformal and rectangular groundplane configurations. Considering applied power levels restricted to 15 W, treatment volumes (T>410C) and depth from the skin surface were 11.32 cm3 and 27.94 mm, respectively, for the conformal groundplane configuration, and 2.79 cm3 and 19.72 mm, respectively, for the rectangular groundplane configuration. E-field back-radiation reduced by 85.06% for the conformal groundplane compared to the rectangular groundplane configuration. A prototype antenna with rectangular groundplane was fabricatd and experimentally evaluated. The groundplane was created by printing silver ink (Metalon JS-B25P) on polyethylene terephthalate (PET) film surface. Experiments revealed stable antenna performance for power levels up to 15.3 W. In conclusion, the proposed patch antenna with conformal groundplane and prined ink technology shows promising performance to be integrated in a clinical array system.

There are many devices available for measuring this pressure, but differences in the design of the systems used, measurement locations, protocols, and operators result in different pressures being measured for the same garment. This article explores the construction of these compression-measuring devices and the sensing involved in order to highlight the potential causes of these discrepancies. The Tension–Elongation profiles of six compression hosiery samples were then measured, and a method of verifying the point pressure measurements from current techniques was proposed and tested. The results of this analysis show that there was an average discrepancy of 1–5 mmHg between point pressure measurements and those predicted from the Tension–Elongation profiles. With respect to on-body measurements, this technique predicted a maximum change in pressure of 3 mmHg for the samples tested.

AU - Peters, Kara T2 - COMPOSITES PART B-ENGINEERING AB - Abstract Due to their high flexibility, high tensile strain and high fracture toughness, polymer optical fibers (POF) are excellent candidates to be utilized as embedded sensors for structure health monitoring of fiber reinforced composites. In 3D orthogonal woven structures yarns are laid straight and polymer optical fiber can be easily inserted during preform formation either as a replacement of constituents or between them. The results of the previous paper indicated how an optic fiber sensor can be integrated into 3D orthogonal woven preforms with no signal loss. This paper addresses whether incorporating POF into 3D orthogonal woven composites affects their structure integrity and performance characteristics. Range of 3D orthogonal woven composites with different number of layers and different weft densities was fabricated. The samples were manufactured with and without POF to determine the effect of embedding POF on composite structure integrity. Bending, tensile strength tests, and cross section analysis were conducted on the composite samples. Results revealed that integrity of 3D orthogonal woven composite was not affected by the presence of POF. Due to its high strain, embedded POF was able to withstand the stresses without failure as a result of conducting destructive tests of the composite samples. Micrograph of cross-section of composite samples showed that minimum distortion of the yarn cross-section in vicinity of POF and no presence of air pocked around the embedded POF which indicates that 3D woven preform provided a good host for embedded POF.

Addition of BaTiO3 did not alter fiber morphology significantly. Particularly, the stability of electrostatic filtration performance was found to be promising with the addition of BaTiO3. Possible microstructural changes after addition of BaTiO3 were investigated via wide angle X-ray diffraction. Changes in crystal structure of PP upon addition of BaTiO3 did not deteriorate electrostatic properties.Copyright 2015 American Association for Aerosol Research DA - 2015/8/3/ PY - 2015/8/3/ DO - 10.1080/02786826.2015.1061649 VL - 49 IS - 8 SP - 666-673 SN - 1521-7388 ER - TY - JOUR TI - Shopping and virtual communities for consumers with physical disabilities AU - Annett-Hitchcock, Kate AU - Xu, Yingjiao T2 - International Journal of Consumer Studies AB - Abstract The purpose of this exploratory study was to investigate the use of virtual communities for clothing shopping by consumers with physical disabilities, and to explore the role that these communities play in their clothing shopping experiences. An international virtual community created for consumers with disabilities was identified using keywords through search engine directories. The content of discussion forums was identified and analysed with the assistance of the qualitative research software tool, QSR NVivo 9.0. The content was coded to allow categories and themes to emerge. Thirty‐one categories, which were dispersed between three major themes (self, product, market), emerged from data analysis. In the discussions, various communication channels and social media sites were mentioned, and users enhanced their discussion topics with a photograph of a product or an Internet link, providing further assistance to peers. Consumers also shared personal information, such as life experiences. The results of this study may provide significant implications to retailers in their efforts to target these consumers, in various areas including product development, branding, marketing, customer relationship and managerial strategies. There may also be relevance for development of other consumer goods and sales to other target markets. Using online discussion forums to probe for product development and brand ideas has not been widely addressed, nor has the information search process for people with disabilities. The use of QSR NVivo software is new for a study such as this and should be explored in greater depth for future research with this type of data.

AU - Peters, Kara T2 - SMART MATERIALS AND STRUCTURES AB - This study demonstrates that standard polymer optical fibers (POF) can be directly integrated into composites from 3D orthogonal woven preforms during the weaving process and then serve as in-situ sensors to detect damage due to bending or impact loads. Different composite samples with embedded POF were fabricated of 3D orthogonal woven composites with different parameters namely number of y-/x-layers and x-yarn density. The signal of POF was not affected significantly by the preform structure. During application of resin using VARTM technique, significant drop in backscattering level was observed due to pressure caused by vacuum on the embedded POF. Measurements of POF signal while in the final composites after resin cure indicated that the backscattering level almost returned to the original level of un-embedded POF. The POF responded to application of bending and impact loads to the composite with a reduction in the backscattering level. The backscattering level almost returned back to its original level after removing the bending load until damage was present in the composite. Similar behavior occurred due to impact events. As the POF itself is used as the sensor and can be integrated throughout the composite, large sections of future 3D woven composite structures could be monitored without the need for specialized sensors or complex instrumentation.

AU - Kim, Y. AU - Powell, N. B. T2 - JOURNAL OF THE TEXTILE INSTITUTE AB - AbstractBinding off is utilized to finish a column of stitches on knitted fabric edges. A binding-off process can be performed by manual or mechanical methods involving hand knitting, overlocking, and linking processes. Binding off also can be achieved on automated flat-knitting machines by a combination of loop transfer and racking techniques. A binding-off process on the computerized knitting machinery provides several potential benefits such as minimizing labor intensive sewing or linking processes, production of constant quality products, and other benefits. However, in order to obtain the bound-off knit edges on computerized knitting machines, it is significant to not only provide appropriate values of loop lengths and machine tensions but also to choose suitable types of binding-off methods. This research introduces three different types of binding-off processes on neck edges conducted on automated complete garment knitting machines and investigates the seam strength and elongation of the neck edges by the three binding-off methods.Keywords: knittingbinding offcomplete garmentstensile propertiestightness factor DA - 2015/3/4/ PY - 2015/3/4/ DO - 10.1080/00405000.2014.922243 VL - 106 IS - 3 SP - 334-341 SN - 1754-2340 KW - tensile properties KW - tightness factor KW - complete garments KW - knitting KW - binding off ER - TY - JOUR TI - Reactive compatibilization of polyamide 6/polyethylene nonwoven based thermoplastic composites AU - Dasdemir, Mehmet AU - Maze, Benoit AU - Anantharamaiah, Nagendra AU - Pourdeyhimi, Behnam T2 - EUROPEAN POLYMER JOURNAL AB - The interface of polyamide 6/polyethylene (PA6/PE) was altered with compatibilizers in an effort to promote adhesion between PA6 reinforcement and PE matrix in nonwoven based thermoplastic composites. The compatibilizers chosen were triblock copolymer of styrene and ethylene/butylene (SEBS) and maleic anhydride (MA) functionalized SEBS with 1 wt% (SEBS-g-MA1) and 2 wt% (SEBS-g-MA2) MA contents. The interfacial adhesion in PA6/PE + Compatibilizer laminates was characterized using asymmetric double cantilever beam (ADCB) test. The effects of compatibilizer type, functional group content and concentration on the interfacial fracture toughness were determined. Also, the influence of lamination temperature and time on the interface enhancement was studied. After performing the compatibilization at composite fabrication stage, tensile responses of PA6/PE composites were greatly improved in the presence of functional compatibilizers. The best improvement on the overall tensile properties was achieved with SEBS-g-MA2 at the lowest compatibilizer concentration level of 2 wt%. The examination of fractured surfaces showed the clear evidence of the enhanced adhesion of matrix polymer to reinforcement fiber for the composites including SEBS-g-MA1 and SEBS-g-MA2. These results suggest that reactive compatibilization was achieved during composite fabrication stage and improved the adhesion between PA6 and PE resulting in a higher load transfer and better mechanical properties.
