AU - Shim, Eunkyoung AU - Mukundan, Rangachary AU - Borup, Rodney L. AB - The gas diffusion layer (GDL) plays a key role in the overall performance/durability of a polymer electrolyte fuel cell (PEFC). Of profound importance, especially in the context of water management and flooding phenomena, is the influence of the underlying pore morphology and wetting characteristics of the GDL microstructure. In this article, we present the digital volumetric imaging (DVI) technique in order to generate the 3-D carbon paper GDL microstructure. The internal pore structure and the local microstructural variations in terms of fiber alignment and fiber/binder distributions are investigated using the several 3-D thin sections of the sample obtained from DVI.

T2 - Journal of the Korean Society of Clothing and Textiles AB - New technology that includes 3D body scanning, digital virtual human, and digital virtual garments has had a significant impact on the current apparel industry. Virtual simulation technology enables the visualization of a 3D virtual garment on a virtual avatar so that consumers can try on garments with their virtual avatars before purchasing. However, the manual virtual avatar provided for online apparel shopping currently has revealed limitations on the different body sizes and shapes of customers. This study analyzes the process of designing the automatic virtual avatar and the manual virtual avatar using OptiTex software; in addition, the study compares the practicality of the automatic virtual avatar with that of the manual virtual avatar. Data was examined by evaluating how much each virtual avatar is similar to the real body and how well it matched the needs of the current apparel industry. In the study, Avatar 1 was automatically created from three-dimensional body scan data and Avatar 2 was manually created from body measurements. The virtual avatar images laid over a real body image and the results were evaluated by comparing the simulated sizes of virtual avatars with those of a real body. Consequently, Avatar 1 was evaluated as more similar to the real body than Avatar 2 in all five body shapes. This study illustrates that an automatic virtual avatar might solve the fit problem that is the most common reason for a high return rate for online shopping. The results show that future virtual simulation technology needs to be improved for the practicality of the virtual avatars.

A social exchange perspective AU - Jin, B. AU - Park, J.Y. AU - Kim, H.-S. T2 - Behaviour & Information Technology AB - A growing number of firms are using online communities (OCs) as integral parts of their strategies because of the value an OC provides to a firm. This study maintains the commitment to an OC to be critical in developing a sustainable OC and examines how members' commitment to an OC develops in the context of OCs hosted by firms and freely available to anyone. Built on the social exchange theory, the proposed model posits that two aspects of OC attributes (Sociability and Usability) facilitate members' participation in an OC, as well as bring social and functional benefits to participants. In return for the benefits gained from OC participation, participants reciprocate with affective and calculative commitment to the OC. Data were collected via online survey from OC participants who were 18 years old or above and resided in South Korea. An analysis of 595 cases supported the proposed model. Results indicated that the members' perceived social benefits from active OC participation led to an affective commitment to the OC, while members' perceived functional benefits led to a calculative commitment to the OC. Theoretical and managerial implications were suggested based on the findings.

AU - Jin, B. AU - Gavin, M. T2 - Journal of the Korean Society of Clothing and Textiles AB - Emotion directly affects consumer buying behavior. This study examines Chinese consumers' emotion elicitation process toward a U.S. apparel brand in the Chinese market. Employing a cognitive appraisal theory, this study proposed and tested a conceptual model incorporating three factors of consumer global orientation as antecedents of consumer emotion and purchase intention as a consequence of emotion. Among the ten proposed hypotheses, eight were supported. Of the three antecedents of consumer emotion, exposure to global mass media and cultural openness positively increased Chinese consumers' appraisals of a U.S. apparel brand. Unlike these two antecedents, the effects of exposure to mass migration on consumer appraisals were found to be non significant. The relationships between appraisal dimensions and positive emotion were all supported. Finally, this study confirmed that positive emotions increased Chinese consumers' purchase intentions of a U.S. apparel brand. Theoretical and managerial implications were discussed based on the findings.

AU - Farr, C. T2 - Family and Consumer Sciences Research Journal AB - While nearly 90% of apparel consumed in the United States is sourced overseas, limited empirical research of this practice has been conducted. To provide an in‐depth understanding of U.S. apparel manufacturers’ global sourcing practices, this study examined the differences in selection criteria and benefits and challenges associated with global sourcing based on two firm characteristics (sourcing items and top management’s commitment to global sourcing). Analyses of data collected from U.S. apparel manufacturers revealed no significant differences in supplier selection criteria or in perceived benefits and challenges by sourcing items. However, a significant difference was found based on top management’s commitment to global sourcing. That is, firms with strong commitment from top management placed significantly more weight on sourcing country when selecting overseas partners, perceived more benefits of global sourcing, and perceived fewer challenges in risks associated with foreign trade than did firms with low commitment from top management. An implication for academia is that firms’ managerial characteristics should be taken into account in examining the effectiveness of global sourcing.

AU - Kim, J. T2 - International Review of Retail, Distribution and Consumer Research AB - This study compared customers of multichannel retailers with customers of pure e-tailers in their evaluations of online store attributes and the attributes' impacts on e-loyalty. Analyses on the data of 164 (47.7%) customers of multichannel retailers and 180 (52.3%) customers of pure e-tailers in Korea largely supported our hypotheses. In evaluation of six online store attributes, communication and promotion aspects were evaluated more highly for multichannel retailers than for pure e-tailers. E-loyalty was found to be higher for pure e-tailers than for multichannel retailers. In comparing the impact of online attributes on e-loyalty, this study found invariance by e-tailing structure. Specifically, the impacts of merchandize assortment/information and security/privacy on e-loyalty were significant for both customers of multichannel and pure e-tailers; however, the impacts were higher for multichannel customers for both attributes. Communication and website design impacted e-loyalty for multichannel customers, but not for pure e-tailer customers. Neither order fulfillment nor promotion aspects contributed to e-loyalty in customers of either type of e-tailer. The findings were interpreted by Korean business structure (multichannel and pure e-tailer), and managerial implications were suggested based on the findings.

AU - Park, J.Y. AU - Kim, J. T2 - Behaviour & Information Technology AB - This study examines the synergistic interchange between online and offline operations. To this end, this study proposed a multichannel performance model integrating Herzberg's (Herzberg 1966 Herzberg, F. 1966. Work and the nature of man, Cleveland, OH: World Publishing. [Google Scholar]: Work and the Nature of Man, World Publishing, Cleveland, OH) motivation-hygiene theory and Thorndike's (Thorndike 1920 Thorndike, E. L. 1920. A constant error in psychological ratings. Journal of Applied Psychology, 4: 25–29. [Crossref] , [Google Scholar]: J. Appl. Psychol., 4, 25 – 29) halo effect, and empirically tested it. The essence of the model was that e-satisfaction is formed by a varying influence of online (basic and marketing-related attributes) and offline (firm reputation, consumer offline channel use, and consumer offline satisfaction) factors, which then increases e-loyalty. Analyses on a sample of 203 multichannel consumers revealed that, in general, the hypothetical paths were significant except in two cases. In a multichannel's online operation, marketing-related online attributes (e.g. merchandising) exerted significant influence on e-satisfaction, but basic attributes (e.g. security) did not. In a multichannel's offline operation, firm reputation and consumer offline satisfaction contributed to increasing e-satisfaction. Both firm reputation and consumer offline channel use increased consumer offline satisfaction, which in turn increased online satisfaction. However, consumer offline loyalty did not transfer to online loyalty. Theoretical and managerial implications were suggested based on findings.

T2 - Clothing & Textiles Research Journal AB - To help U.S. apparel companies more successfully pursue market opportunities in China, this study aimed to systematically understand Chinese college students’ purchase behaviors toward foreign brand jeans. Considering Chinese value changes as a result of modernization and rapid economic growth, this study proposed a research model incorporating two extended Fishbein models, Lee’s modified Fishbein model and Ajzen’s theory of planned behavior. To test the research model, a total of 238 valid data sets were collected at two universities in Shanghai, China. Structural and measurement models were estimated using LISREL 8.80. Findings indicated that perceived behavioral control had the strongest direct influence on Chinese college students’ purchase intention of foreign brand jeans. Among social pressure factors, face-saving had a stronger impact on purchase intention than subjective norm did. Based on findings, theoretical and managerial implications were provided.

This study is to understand the purchase behaviors of Korean college students toward foreign brand jeans to help Korean jean brands enhance their competitive advantages over foreign brand jeans in the Korean market. Considering perceptions of Korean consumers toward foreign brands and traditional value changes, this study proposed a research model incorporating two extended behavioral intention (BI) models, Lee`s modified BI model and Ajzen`s theory of planned behavior. To test the research model, a total of 240 valid data sets were collected from college students in Busan, Korea. Structural and measurement models were estimated using LISREL 8.80. Because face saving failed to attain internal validity, the research model was revised to eliminate face saving. The findings indicated that perceived behavioral control had the strongest direct influence on purchase intentions of Korean college students for foreign brand jeans. Group conformity and subjective norm had non-significant direct impacts on purchase intention, whereas group conformity had an indirect impact on purchase intention through attitude. Based on the findings, theoretical and managerial implications were provided.

AU - Park, J.Y. AU - Ryu, J.S. T2 - Journal of Fashion Marketing and Management AB - Purpose US apparel firms have been relatively slow exploring Chinese and Indian apparel markets, despite the countries' tremendous growth potentials. To help US apparel firms successfully enter these promising markets, this study aims to compare evaluative attributes that Chinese and Indian consumers utilize when purchasing denim jeans. Design/methodology/approach Data were collected in Shanghai, China and Bangalore, India. Findings The results of the study confirmed that Chinese and Indian consumers ranked attributes differently. Chinese consumers placed the highest importance on price, followed by fitting, brand country of origin, quality, and design, whereas Indian consumers placed importance on fitting, brand country of origin, design, price, and quality, in descending order. Research limitations/implications Caution needs to be exercised in generalizing the findings since the data for this study were collected from one city in each country. The study tested the idea that the importance of attributes would be different between Chinese and Indian consumers as their cultures and retail development stages differ. This idea was supported in conjoint analysis. Practical implications The findings indicate that a regional approach, assuming that all Asian markets are the same, is inappropriate. Thus, US apparel firms need to pay careful attention to differences in each Asian market. Originality/value China and India have been compared frequently in various ways: growth potential, market size, and population. Surprisingly, however, no study has attempted to compare Chinese and Indian consumers' evaluative criteria for apparel products. This is the first empirical study to show the differences between Chinese and Indian consumers in evaluating apparel products.

T2 - Gerontechnology AB - This research describes the functionality of a Near and Far Environmental Awareness System (NaFEAS) intended to be worn as a computer-based vest undergarment to support social interaction for older adults with severe visual impairments. The system is designed to facilitate wayfinding (orientation, navigation) and object recognition. The design framework was derived from embodied cognition. Methods Five consultants with Severe Visual Impairments (SVIs) formed a participatory design team who worked on the first iteration of the NaFEAS prototype. We used information from the team to develop a questionnaire to elicit scenario-based information from older adults with SVIs. Data were also collected using an online questionnaire that provided a description and broad scenarios indicating how NaFEAS could operate in a party setting and the garment and material design of the NaFEAS vest. Fifty adults ages 55 and over responded. Analysis methods included χ2 analysis of frequency data and content analysis of qualitative data. Results revealed important requirements for the NaFEAS system. Navigation through party environments, especially those containing stairs and balconies, was a critical need. Although relatively homogeneous in responses, χ2 tests revealed that women considered NaFEAS to be more beneficial for introducing others and playing games compared to men. Older adults who attended social events more frequently wanted the system to support remembering names, compared to those who attended parties less frequently. The most important garment features were functionality, overall appearance, and usability. Discussion and conclusion User requirements centered on being able to locate key people, having to rely less on others, and having a wearable computer garment that is attractive and easy-to-use. Further implications involved the importance of designing the NaFEAS as a tool to be used with other mobility aids such as walkers and hearing aids.

The goal of the project was to revitalize product lines of the two brands by incorporating student ideas for new solutions, thereby giving the students practical experience with a real-life industry situation. There were a number of key players involved in the project. A privately-owned department store chain based in the southeastern United States which was seeking an academic partner had recognized a need to update two existing private label brands. They targeted middle-aged consumers looking for casual, moderately priced merchandise. The company was seeking to change direction with both packaging and presentation, and possibly product design. The branding and product development divisions of the company contacted professors in an academic department of a large southeastern state university. Two of the professors agreed that the task would be a good fit for their classes -one was a junior-level Intermediate Brand Management class; the other was a senior-level Fashion Product Development class. The professors felt that by working collaboratively on the project, students would be exposed to a real world scenario, within the security of an academic learning environment. Collaboration within an interdisciplinary team has the advantage of providing experiences and resources beyond the capabilities of a single student and adds “brainpower” to problem-solving processes (Lowman 2000). This goal of improving the capabilities of students directed the instructors in each class to form interdisciplinary teams between the Branding and Product Development classes. In addition, many universities are employing industry partnerships in research and teaching, where collaboration within temporal (semester) and physical (classroom/lab) constraints help to increase students' knowledge and experience of a real-world situation. At the University of Tennessee, the Center of Industrial Services and UT-Knoxville's College of Engineering worked with a company to develop design improvements in its U.S. operations. In this study, Because should be lower case b with a private label retail brand, Wickett, Gaskill and Damhorst's (1999) revised Retail Apparel Product Development Model was used by the product development and brand management teams. This framework was chosen because it addresses apparel product development from the concept to the retail stage. Two classes were involved in this project: a junior level Brand Management class and a senior level Fashion Product Development class. Seven teams were formed which included four students from Brand Management and two students from Product Development. The classes were taught the same semester, but not at the same time. At the beginning of the semester, each class was introduced to the industry partner and given the problem. Half the teams were assigned to the men's brand and half to the women's brand. The teams were responsible for devising approaches to the problem, formulating a timeline for their work, staying in touch with industry representatives and making sure that each member of the team contributed in a positive way. The objective for the teams was to plan, develop, and present a product line using merchandising processes (following the Wickett, Gaskill and Damhorst model) and develop new branding strategies for the proposed lines. The teams performed trend, color, fabrication and target market research; developed sketches for a line; edited the sketches and presented their line plans; wrote specifications; fitted prototypes on fit models, and developed final production samples for presentation to industry. The branding students developed a SWOT analysis, a Brand Measurement report, a mind-map for the brands and a fully integrated Marketing Report which was presented alongside the ideas for the new lines. In future if the opportunity arises to work in this collaborative way with an existing company who wishes to look both at branding and product development strategies, classes will be scheduled at the same time so that students have more time to meet and discuss timelines and assigned tasks. As it was, student groups had to meet outside of each class time and this proved to be a challenging though not uncommon part of teamwork (Pfaff and Huddleston, 2003). Although the logistics of this exercise were time-consuming to set up and administer, professors felt that the benefits to students were multiple. The most important benefit, according to student feedback from both classes, was the opportunity to work with industry professionals, follow their process, and see the results of their work evaluated by the people who made the decisions at the company level. Faculty members were grateful to have a “real-world” case to work with in the classroom to provide focus. Creative ideas and strategies were traded as plans were made, extending and strengthening the departmental links between the branding and product development areas. By working not only with students coming from a different knowledge base, but also having to keep in contact with the industry partner and follow the framework and timeline of industry practice, student teams were challenged to produce excellent and innovative work under new circumstances. Working on the product development and branding for “real-life” brands that are struggling gave students an opportunity to see how closely their coursework ties in with the real-world and how creativity, collaboration and flexibility are necessary components of both the design and business aspects of company operations. Industry personnel were impressed by (a) the level and depth of knowledge and execution in the student projects, and (b) the creativity of new ideas for the brands.

The sample included 117 working women with a variety of disabilities. Principle Components Factor Analysis and Multiple Regression were used to analyze the data. Three distinct factors emerged to represent clothing problems (called Design, Materials Performance, and Dressing) and four distinct factors emerged to represent physical limitations (called Limbs/Outer Extremities, Central Core/Torso, Central Nervous System, and Intellect, Vision and Hearing). Regression analysis showed that the physical limitations impact each of the three clothing factors. The study extends research by focusing on an underserved market segment and providing the apparel industry with a potential method of addressing the needs of that market. The study also contributes to interdisciplinary research by further developing an Inclusive Design model for apparel product development.

T2 - Journal of the Textile Institute AB - The effect of environmental conditions (temperature and relative humidity) and contact conditions (yarn tension and speed) on static generation and dissipation of polyester flat continuous filament yarn, when rubbed against stainless steel was analyzed. A newly developed device, housed in an environmental room, was used to charge the yarn while moving under desired tension. The charge potentials were measured at two different positions in real time. These measurements and previously established exponential relationship permitted the calculation of the initial potential (at the generation point) and a ‘characteristic decay time’, which is a measure of static dissipation. Experimental data showed that temperature, humidity, yarn tension, and yarn speed have significant effects on static generation; while temperature, humidity, and yarn speed yielded statistically significant changes on static dissipation. Anomalous behavior of static charge when measured at a temperature of 35°C, provided a meaningful clue to control the environmental conditions in the textile industry.

J. Carroll derived the equation to show that a symmetric liquid droplet sitting on a thin cylindrical fiber would acquire a bell shape at equilibrium. We have extended his derivation to describe a drop located at the top end of a vertical, cylindrical fiber. By minimizing the Gibbs free energy of the drop at the fiber tip, it was found that the drop consists of two portions, a spherical cap on the fiber tip and a full, symmetrical bell located on the fiber body adjacent to the fiber tip. The experimental verification of the predicted shapes was performed using water, ethylene glycol, and Kaydol drops on nylon cylindrical fibers. Only four parameters are required to obtain agreement between the theoretical shape and the observed shape: the drop volume, the fiber radius, the surface tension of the liquid, and the Young contact angle of the liquid on a flat surface of the same composition as the fiber.

AU - Roberts, Kim G. AU - Hyde, G. Kevin T2 - TEXTILE RESEARCH JOURNAL AB - Atomic layer deposition (ALD) has recently been demonstrated as a novel method for the creation of nanoscale coatings on fiber-based materials. The ALD process has proven effective in altering the surface energy of both woven and nonwoven materials. In this work, the effect of fabric weave geometry on the behavior of ALDmodified fabrics has been studied. Aluminum oxide ALD was used to modify a series of fabric weaves which were then analyzed using sessile contact angle measurements. The experimental results demonstrated the ability of the ALD process to modify the surface energy of a variety of weave structures, regardless of the inter-fiber spacing within the yarns. At the same time, the amount of fiber spacing, which is influenced by the weave geometry, changes the effect of the ALD coatings on fabric hydrophobicity and hydrophilicity. The results of this work demonstrate the versatility of the ALD process when modifying woven fabric structures and its potential as a method for nanoscale textile finishing.

AU - Rojas, Orlando J. T2 - LANGMUIR AB - This study investigates the adsorption of a symmetric triblock nonionic polymer comprising ethylene oxide (EO) and propylene oxide (PO) blocks (Pluronic P-105, EO37PO56EO37) on a range of substrates including hydrophobic, i.e., polypropylene (PP), poly(ethylene terephthalate) (PET), nylon, and graphite, and hydrophilic, i.e., cellulose and silica. The adsorption process and the structure of the hydrated adsorbed layers are followed by quartz crystal microgravimetry (QCM), surface plasmon resonance (SPR), and atomic force microscopy. The unhydrated surfaces are characterized by ellipsometry and contact angle techniques. The adsorption kinetics and the extent of adsorption are determined by monitoring the changes in resonance frequency and refractive index of sensors coated with ultrathin films of the various substrates. Langmuirian-type adsorption kinetics is observed in all cases studied. The amount of adsorbed Pluronic on hydrophobic polymer surfaces (PP, PET, and nylon) exceeds that on the hydrophilic cellulose. The hydrophobic (graphite) mineral surface adsorbs relatively low polymer mass, typical of a monolayer, while micellar structures are observed on the hydrophilic silica surface. The amount of water coupled to the adsorbed polymer layers is quantified by combining data from QCM, and SPR are found to increase with increasing polarity of the substrate. On the basis of contact angle data, the nonhydrated adsorbed structures produce modest increases in hydrophilicity of all the substrates investigated. Overall, insights are provided into the structure and stability of both hydrated and nonhydrated adsorbed triblock copolymer.

AU - Huh, You AU - Suh, Moon W. T2 - JOURNAL OF THE TEXTILE INSTITUTE AB - Most of the random signals used to analyze the quality of an industry product or process disturbance have properties that can be described by an autocorrelation function. This research suggests a novel method that can generate stochastic signals that have specific autocorrelated properties. On the basis of the power spectrum and the inverse Fourier transform, stochastic signals were generated by the new method, which applies the random phase angle distribution to the power spectrum of the signal. Then, the autocorrelation functions of the generated signals were compared with the assigned autocorrelation functions. Results showed that stochastic signals with five different types of autocorrelation functions could be effectively produced by the suggested method, which we have called the “Random Phase Spectral Method”. Ensembles of the generated stochastic signals could find applications in analyzing dynamic systems that work under perturbed circumstances. The effect of the autocorrelated perturbations in the model parameters or process conditions on the dynamic state of a process system could also be estimated by simulation using the stochastic signals generated by the RPS method.

T2 - JOURNAL OF THE TEXTILE INSTITUTE AB - Three‐dimensional structural analysis utilizing digital volumetric imaging is used to fully understand the splitting of bicomponent fibers by hydroentangling. It was found that lower fabric density measured by solid volume fraction, higher degree of splitting and a higher thickness fiber orientation direction was evident at the jet streak valley position. Splitting was found to be more dominant on the surface of the fabrics. Washing the fabric increased fiber splitting and also resulted in more uniform splitting, but did not result in any significant change in local fiber orientation, that is, the structure.

T2 - TENSIDE SURFACTANTS DETERGENTS AB - Abstract Reverse phase HPLC (High Performance Liquid Chromatography) was used to analyze the length distribution of polyoxyethylene (POE) chains in commercial surfactants that can be used as melt additives for hydrophilic polypropylene surface modification. Ten nonionic surfactants including ethoxylated alcohols, nonyl phenols and amines, PEG esters, and mono glycerides were investigated. HPLC methods described herein are capable of analyzing ethoxylated nonionic surfactants and offer the advantage of separating the components in surfactants according to both the hydrophobe and hydrophile chain length. Moreover, the method is rapid and gradient elution allows for good baseline separation of the several components in the additives.

AU - Montero, Gerardo A. AU - Kim, Soo Hyun AU - King, Martin W. T2 - ACTA BIOMATERIALIA AB - Current surgical therapy for diseased vessels less than 6mm in diameter involves bypass grafting with autologous arteries or veins. Although this surgical practice is common, it has significant limitations and complications, such as occlusion, intimal hyperplasia and compliance mismatch. As a result, cardiovascular biomaterials research has been motivated to develop tissue-engineered blood vessel substitutes. In this study, vascular tissue engineering scaffolds were fabricated using two different approaches, namely melt spinning and electrospinning. Small diameter tubes were fabricated from an elastomeric bioresorbable 50:50 poly(l-lactide-co-epsilon-caprolactone) copolymer having dimensions of 5mm in diameter and porosity of over 75%. Scaffolds electrospun from two different solvents, acetone and 1,1,1,3,3,3-hexafluoro-2-propanol were compared in terms of their morphology, mechanical properties and cell viability. Overall, the mechanical properties of the prototype tubes exceeded the transverse tensile values of natural arteries of similar caliber. In addition to spinning the polymer separately into melt-spun and electrospun constructs, the approach in this study has successfully demonstrated that these two techniques can be combined to produce double-layered tubular scaffolds containing both melt-spun macrofibers (<200microm in diameter) and electrospun submicron fibers (>400nm in diameter). Since the vascular wall has a complex multilayered architecture and unique mechanical properties, there remain several significant challenges before a successful tissue-engineered artery is achieved.

P. AU - King, M. W. AU - Zikry, M. A. T2 - JOURNAL OF BIOMECHANICS AB - Barbed surgical sutures are a new type of knotless suture that are currently being used clinically in cosmetic and plastic surgery procedures for faster healing and better cosmesis. Clinical studies are also underway to evaluate their performance in other deep tissue applications. However, little is known about their intrinsic mechanical behavior and their interactions with surrounding tissues. The primary objective of the current study was to analyze the mechanical behavior of barbed sutures using a finite element analysis approach. First, the effect of applying a point-pressure load to the tip of the barb and measuring its effect on barb displacement was studied. Second, the effect of an applied displacement to a barb anchored either in skin or tendon material for both the suture and the surrounding tissue. The results indicate that the flexibility of the barb can be increased or decreased by changing the barb geometry. It was concluded that the barb geometry and design need to be modified for use with different types of tissue. For example, in order to achieve the best mechanical anchoring with skin tissue the barb should be more flexible compared to the one designed to work with tendon tissue. The uniqueness of this study is that it is the first to establish a virtual prototyping and designing method for barbed sutures. For example, a new and improved virtual design of barb geometry is proposed and validated. It also provides the first report on how to develop a virtual bench top suture/tissue pullout testing environment.

AU - Chun, Heuiju AU - Berger, Roger L. AU - Bloomfield, Peter T2 - TEXTILE RESEARCH JOURNAL AB - Fundamental theories governing the number of fiber intersections in random nonwoven fiber webs were developed based on the planar geometry of fiber midpoints distributed in a two-dimensional Poisson field. First, the statistical expectation and variance for the number of fiber intersections in unit web area were obtained as functions of a fixed number of fibers with equal lengths. The theories were extended to the case of a two-dimensional Poisson field by assuming that the number and locations of the fibers are random. The theories are validated by a newly developed computer simulation method employing the concept of “seeding region” and “counting region.” Unlike all previously published papers, it was shown for the first time that the expectations and variances obtained theoretically matched that from computer simulations almost perfectly, validating both the theories and simulation algorithms developed.

P. AU - King, M. W. T2 - JOURNAL OF BIOMECHANICS AB - The focus of the current work was to study how the geometric design of a single barbed monofilament suture effects its biomechanical behavior. Different cut angles and cut depths of barbs were prepared and tested in vitro for their tensile and tissue anchoring properties by means of a novel suture/tissue pullout test. Experiments were also performed using bovine tendon and porcine skin tissues. The experimental results revealed that since tendon tissue has a higher modulus than skin it needs a more rigid barb to penetrate and anchor the surrounding tissue. A cut angle of 150° and a cut depth of 0.18 mm are therefore recommended. On the other hand, for the softer skin tissue, a cut angle of 170° and a cut depth of 0.18 mm provides a more flexible barb that gives superior skin tissue anchoring. These findings confirm that the future development of barbed suture technology requires a detailed understanding of the biomechanical properties of the tissue in which they are to be used. This will lead to the future development of a range of tissue-specific barbed sutures.

T2 - LANGMUIR AB - Atomic layer deposition (ALD) of aluminum oxide on nonwoven polypropylene and woven cotton fabric materials can be used to transform and control fiber surface wetting properties. Infrared analysis shows that ALD can produce a uniform coating throughout the nonwoven polypropylene fiber matrix, and the amount of coating can be controlled by the number of ALD cycles. Upon coating by ALD aluminum oxide, nonwetting hydrophobic polypropylene fibers transition to either a metastable hydrophobic or a fully wetting hydrophilic state, consistent with well-known Cassie−Baxter and Wenzel models of surface wetting of roughened surfaces. The observed nonwetting/wetting transition depends on ALD process variables such as the number of ALD coating cycles and deposition temperature. Cotton fabrics coated with ALD aluminum oxide at moderate temperatures were also observed to transition from a natural wetting state to a metastable hydrophobic state and back to wetting depending on the number of ALD cycles. The transitions on cotton appear to be less sensitive to deposition temperature. The results provide insight into the effect of ALD film growth mechanisms on hydrophobic and hydrophilic polymers and fibrous structures. The ability to adjust and control surface energy, surface reactivity, and wettability of polymer and natural fiber systems using atomic layer deposition may enable a wide range of new applications for functional fiber-based systems.
