This paper aims to investigate fabric simulation parameters, including digitized physical properties and particle distance that influence drape simulation. To achieve this goal, the paper consists of three phases. The first phase focuses on developing a reliable virtual drape test setup compatible with the Cusick drape tester by adjusting different variables, such as the cylinder's height and ring diameters. The second phase investigates the drape coefficient (DC) influencing parameters using the devised drape test method, specifically focusing on digitized physical properties obtained from standard testing equipment or a simplified fabric kit. The last phase investigates the effect of particle distances on virtualized fabric. By understanding the simulation parameters that affect the virtualized fabric, the study suggests approaches to minimize the gap and optimize the ability of simulator technology.}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Youn, Seonyoung and Knowles, Caitlin G. and Mills, Amanda C. and Mathur, Kavita}, year={2024}, month={Feb} } @article{youn_mills_west_denhartog_mathur_2024, title={Enhancing Biosignal Quality in Electrocardiogram Monitoring Garments: Validation of a Simulation-Based Contact Pressure Model}, volume={2}, ISSN={["2771-9545"]}, url={https://doi.org/10.1021/acsaenm.4c00178}, DOI={10.1021/acsaenm.4c00178}, abstractNote={Optimizing contact pressure in a biomonitoring garment system is crucial to improving signal quality by reducing skin impedance and motion artifacts. Building upon previous research, which introduced a strategic methodology for enhancing electrocardiogram (ECG) biosignal quality through material selection and pattern sizing guided by a developed simulation-based contact pressure prediction model (CP model), this study investigates the model's efficacy across varied knits (plain, interlock, plaited single jersey, and plaited interlock) and yarn filament densities to design a more complex ECG chest band. In this study, our CP model demonstrated strong predictive capabilities with R-squared values exceeding 0.87, which are compatible with physical uniaxial tensile test-based prediction showing an R-squared value of 0.88. Our selected appropriate knit substrates (single jersey and interlock plaiting knit) for pattern reduction values of 20 and 5%, respectively, for designing ECG elastic chest bands result in enhanced biosignal quality with signal-to-noise ratios (SNRs) of 42.85 (±0.08) and 40.92 (±0.06), respectively, comparable to the wet electrode with an SNR of 40.02 (±0.32). This study confirms that selected appropriate materials and patterns can significantly enhance ECG signal quality by optimizing contact pressure to the ideal range of at least 0.53 to 1.05 kPa under the chest area, as demonstrated with a female subject.

However, a research gap exists concerning the accuracy of the technology and its applicability to advanced functional apparel manufacturing. The primary research question is to investigate how variations in digitized physical properties obtained from PT measurements and artificial intelligence (AI)-based textile digitization impact the accuracy of a fabric’s mechanical representation. In this study, we aimed to evaluate AI-based textile digitization accuracy using a drape test method. The drape coefficient (DC) analysis revealed that the PT-based simulated DC exhibited a normalized mean absolute error (NMAE) ranging from 2% to 11%, while the AI-based simulated DC showed a range of 3–51%.

This research presents sustainable alternative fibers that show better controlled exhaustion than commercial wipes and textile fibers. Textile and lignocellulosic fibers were prepared, soaked in QAC, and a UV–vis spectrophotometer was used to measure their exhaustion percentages. Factors such as immersion time and concentration of the disinfectant were also investigated, which affect the rate of exhaustion of the disinfectant from the fibers. A higher immersion time resulted in better exhaustion, whereas the total exhaustion decreased with an increase in the initial concentration of the disinfectant. The exhaustion of benzalkonium chloride (BAC) from the commercial wipes was also investigated at different immersion times and BAC concentrations.

Conductive yarns can be incorporated into fabrics with traditional textile techniques, such as weaving, knitting and sewing. The electromechanical properties of conductive yarns are very different from conventional yarns, and they also affect the processability during end-product manufacturing processes. However, systematic evaluation of the electromechanical properties of commercial conductive yarns is still elusive. Different conductive materials and production methods for making conductive yarns lead to diverse electromechanical properties. In this work, three types of conductive yarn with different conductive materials and yarn structures were selected for electromechanical characterization. A total of 15 different yarns were analyzed. In addition, the change of resistance with strain was tested to simulate and predict the possible changes in electrical properties of the yarn during weaving, knitting, sewing and other end uses. It was found that Metal-based yarns have good electrical properties but poor mechanical properties. The mechanical properties of Metal-coated yarns are similar to conventional yarns, but their electrical properties are relatively poor.

However, optimizing biosignal quality, motion artifacts, and wearer comfort in electronic textiles (E-textiles) remains challenging. While designing appropriate contact pressure (CP) is crucial, there is a lack of guidance on proper material selection and sizing for achieving the desired CP. This article presents a novel CP prediction model that utilizes three-dimensional garment simulation (3DGS) to optimize knit textiles for health monitoring. First, a stress test method is devised in the simulator to examine the reliability of simulated stress. Based on understanding the simulated stress mechanism, the CP model is developed using simulation parameters. The model is validated against experimental CP values, exhibiting high accuracy ( ${R}^{{2}}= {0.9}$ ). The effectiveness of the CP model is validated through the demonstration of a customized ECG armband incorporating screen-printed dry electrodes on knit fabrics. Analyzing ECG signals, CP, and applied strains validates the benefits of strategically selected materials and sizing. Specifically, the knit sample with 90% polyester and 10% spandex (S-10) for the 15%–20% range and the knit sample with 85% polyester and 18% spandex (S-18) for the 10%–15% strain range significantly enhance ECG quality, resulting in higher signal-to-noise ratios (SNR) of 33.45 (±1.72) and 34.57 (±0.84)−36.61(±1.81), respectively.

Antiviral treated textiles have the potential to save lives, especially in healthcare settings that rely on reusable patient-care textiles and personal protective equipment. Currently, little is known about the role of textiles in cross-contamination and pathogen transmission, despite the wealth of information on hard surfaces and fomites harboring viruses that remain viable in certain circumstances. In addition, there is no international standard method for evaluating residual viral activity on textiles, which would allow a thorough investigation of the efficacy of antiviral textile products. Therefore, this pilot study aims to develop and refine a standardized protocol to quantitatively evaluate residual viral activity on antiviral textiles. Specifically, we focused on general textiles, such as bed linens, commonly used in healthcare settings for patient care. The Tissue Culture Infectious Dose 50 (TCID50) method is frequently used to quantitatively evaluate viral infectivity on textiles, but has not been established as a standard. This procedure involves observing the cytopathic effect of a given virus on cells grown in a 96-well plate after several days of incubation to determine the infectivity titer. We used HCoV-229E and Huh-7 human liver cancer cells for this investigation. We worked to improve the TCID50 method through variations of different steps within the protocol to attain reproducible results. Our proposed optimized hybrid protocol has shown evidence that the protocol is technically simpler and more efficient, and provides successful, consistent results. The analysis showed a significant difference between the treated fabric compared with controls. }, journal={TEXTILE RESEARCH JOURNAL}, author={Wang, Ziyu and Amanah, Alaowei Y. and Ali, Kiran M. and Payne, Lucy C. and Kisthardt, Samantha and Scholle, Frank and Ormond, R.

Friction testing was completed by sliding a probe across the inside bottom surface of the sock (the part that is usually in‐contact with the bottom of the foot) while instantaneously measuring the frictional force every tenth of a second.ResultsFor both trials (plastic probe and synthetic skin), in the dry condition, knit structure was found to be the most prominent fabric parameter affecting the frictional force experienced at the sock‐skin interface. It was also determined that fiber linear density, and yarn type are tertiary factors affecting the frictional force measured at the sock‐skin interface. Finally, in the dry state, it was determined that fiber composition had seemingly no effect on the frictional force experienced at the sock‐skin interface.ConclusionThis parametric design of experiments has further enhanced the understanding of the tribology at the sock‐skin interface. Through strategic design, four different textile parameters have been investigated, measured, and justified as to how each influence the friction measured between the two interfaces.

However, 3DP fiber-reinforced composite structures suffer from low fiber content compared to the traditional composite, such as 3D orthogonal woven preforms solidified with vacuum assisted resin transfer molding (VARTM) that impedes their high-performance applications such as in aerospace, automobile, marine and building industries. The present research included fabrication of 3DP fiberglass-reinforced nylon composites, with maximum possible fiber content dictated by the current 3D printing technology at varying fiber orientations (such as 0/0, 0/90, ±45 and 0/45/90/−45) and characterizing their microstructural and performance properties, such as tensile and impact resistance (Drop-weight, Izod and Charpy). Results indicated that fiber orientation with maximum fiber content have tremendous effect on the improvement of the performance of the 3DP composites, even though they inherently contain structural defects in terms of voids resulting in premature failure of the composites. Benchmarking the results with VARTM 3D orthogonal woven (3DOW) composites revealed that 3DP composites had slightly lower tensile strength due to poor matrix infusion and voids between adjacent fiber layers/raster, and delamination due to lack of through-thickness reinforcement, but excellent impact strength (224% more strong) due to favorable effect of structural voids and having a laminated structure developed in layer-by-layer fashion.}, number={5}, journal={JOURNAL OF COMPOSITES SCIENCE}, publisher={MDPI AG}, author={Kabir, S.

Textiles next to skin govern the skin microclimate, have the potential to influence the mechanical contact with skin, and contribute to skin comfort and health. The adhesion-friction theory suggests that contact area is a critical factor to influence adhesion, and therefore, friction force. Friction being a surface phenomenon, most of the studies concentrated on the surface profile or topographic analysis of textiles. This study investigated both the surface profiles and the inner construction of the fabrics through X-ray microcomputed tomographic three-dimensional image analysis. A novel nondestructive method to evaluate yarn and fabric structural details quantitatively and calculate contact area (in fiber area %) experimentally has been reported in this paper. Plain and satin-woven fabrics with different thread densities and made from 100% cotton ring-spun yarns with two different linear densities (40 and 60 Ne) were investigated in this study. The measurements from the tomographic images (pixel size: 1.13 μm) and the fiber area % analysis were in good agreement to comprehend and compare the yarn and fabric properties reported. The fiber area % as reported in this paper can be used to evaluate the skin-textile interfaces and quantitatively determine the contact area under different physical, mechanical, and microclimatic conditions to understand the actual skin-textile interaction during any physical activity or sports. The proposed method can be helpful in engineering textiles to enhance skin comfort and prevent injuries, such as blisters and pressure ulcers, in diversified application areas, including but not limited to, sports and healthcare apparel, military apparel, and firefighter's protective clothing. In addition, the images were capable of precisely evaluating yarn diameters, crimp %, and packing factor as well as fabric thickness, volumetric densities, and cover factors as compared with those obtained from theoretical evaluation and existing classical test methods.

Therefore, several approaches have been researched to increase the efficacy of cotton dyeing. One is the cationization, which adds cationic sites to the cellulose. Another is the treatment of the cotton surface with plasma. In this paper, the combination of both techniques was investigated. Two commercially available cationic agents were used: 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CHPTAC) and poly[bis(2-chloroethyl) ether-alt-1,3-bis[3-(dimethylamino)propyl]urea] quaternized, a novel cationic agent also known as Polyquaternium-2 (P42). The plasma treatment was performed using a dielectric barrier discharge atmospheric plasma facility, helium was used as seed gas and 1.5% of oxygen was injected. The cationization and plasma treatment were performed on greige cotton fabric, an innovative and sustainable approach that eliminates conventional scouring and bleaching processes. The cationic and plasma treated samples were dyed using Reactive Red 195 and Acid Blue 260 dyes. The effect of the treatments was evaluated by different characterization techniques such as X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). The plasma treatment slightly increased the light fastness for some samples, but the cationization tends to prevail over the plasma treatment. The best results were attributed to the samples pretreated by CHPTAC, which presented the highest K/S and lowest unlevelness for samples dyed with reactive and acid dyes. CHPTAC is the most common cationic agent for textiles, but its industrial use is limited due to safety criticisms. The combination between plasma and P42 resulted in the same color strength as the conventional reactive dyeing.

The aim of this research was to investigate unique macrostructures of 3D printed samples developed by varying the printing parameters, and their influence on the tensile behavior. Samples developed for this study comprised of nylon matrix reinforced with continuous fiberglass with three varying fiber orientations and four different infill geometries. Tensile properties of the unreinforced and reinforced 3D printed samples were evaluated to investigate the impact of fiber orientation and infill geometries and further benchmarked with traditional 3D orthogonal woven (3DOW) composites. The results indicated that the tensile properties due to fiber orientation mainly dictated the tensile properties more than the cellular structure. The analyses from this study showed that the macrostructure (hence tensile properties) of 3D printed specimens were directly related to the printing parameters that include fiber amount and orientation, void formation and the bonding between individual raster/layers.}, journal={The Journal of The Textile Institute}, publisher={Informa UK Limited}, author={Mathur, Kavita and Kabir, S M Fijul and Seyam, Abdel-Fattah M.}, year={2022}, month={Jan}, pages={1–10} } @article{kabir_mathur_seyam_2020, title={The Road to Improved Fiber-Reinforced 3D Printing Technology}, volume={8}, ISSN={2227-7080}, url={http://dx.doi.org/10.3390/technologies8040051}, DOI={10.3390/technologies8040051}, abstractNote={Three-dimensional printing (3DP) is at the forefront of the disruptive innovations adding a new dimension in the material fabrication process with numerous design flexibilities.

Thus the primary elements of woven fabric design are combination of weaves and blending of colors using such weaves. Weave is the scheme or plan of interlacing the warp and weft yarns that produce the integrated fabric. Weave relates specially to the build or structure of the fabric. Color is differently related to effects of weave and form. The methods of utilization of color in woven textiles depend upon the composition of the weave design to be woven and the structure parameters of the cloth. Color and ornamentation in woven fabrics is imparted through the pre-determined placement and interlacing of particular sequences of yarns. A solid color is produced by employing the same color in warp and weft. On the other hand, different colors may be combined to produce either a mixed or intermingled color effect in which the composite hue appears as a solid color. Figured ornamentation is created through the selection of different groups of colored yarns, placed in the warp and/or in the weft; while in certain patterns, textural effects may be created entirely through the use of different values and closely associated hues of certain colors. The figure is formed for the purpose of displaying different pattern formations, adding dimension or color reinforcement and for enhancing a particular motif. Modern CAD systems provide a variety of design tools that are supported by standardized color databases that allow simulation of weave structures on the computer monitor that could be printed on paper. However, deviations of the color values of these simulations still occur. Also, the color on fully flat fabric simulations on paper or computer screen is twodimensional that differs from the real three-dimensional nature of fabrics and yarns. In textile wet processing, the uses of colorimetry systems and associated software have proven their worth over the years, in objective estimation of color, and have minimized misunderstandings between textile manufacturers and their customers. However, color communication within textile design is largely a subjective process. Recent experimental studies (Osaki 2002; Dimitrovski & Gabrijelcic 2001, 2002, 2004) have revealed that the use of colorimetry has helped to achieve better reproducibility and accuracy in the shade matching of textiles products.

The final visualized color effect is the result of assigning weave designs to different areas of the pattern to be created. The current practice in creating Jacquard woven fabric designs is to produce many samples in a trial‐and‐error attempt to match artwork colors. An ability to simulate accurately the appearance of a design prior to manufacture is highly desirable to reduce trial‐and‐error sample production. No automated accurate digital color methodology is yet available to assist designers in matching the patterned woven fabric to the desired artwork. To achieve this, we developed a geometrical model to predict the color contribution of each yarn on the face of the fabric. The geometrical model combined with a Kubelka‐Munk based color mixing model allowed the prediction of the reflectance properties of the final color for a given design. We compared the predicted and experimental values of the reflectance properties for a range of fabrics using the same geometric model with three separate color mixing models. The geometrical model combined with a log‐based color mixing model produced reasonable agreement between predicted and measured ΔEab, with an average ΔEabof approximately five. © 2009 Wiley Periodicals, Inc.

Jacquard CAD systems dramatically reduce the time to produce fabric from the artwork or target design The process of weave/color selection for each area of the pattern is, however, still highly dependent on the CAD system operator who works from a particular color gamut. Multiple weaving trials are required to get a sample that matches the original artwork since the process requires the designer‘s subjective evaluation.

This is a very time consuming and costly process. In Jacquard woven fabrics, the use of graphical imaging in the creation of the weave structure is very useful, but the accuracy of color rendering is a far more critical attribute. Multiple trials might be required for successful color reproduction in textiles in order to match the desired artwork.
