Flame retardant treated gray cotton fibers were blended with antibacterial treated gray cotton fibers and polyester/polyester sheath/core bicomponent fibers to form high-loft fabrics. The high flame retardancy (FR) and antibacterial property of these high lofts were evaluated by limiting oxygen index, vertical flame testing, and antimicrobial tests against S. aureus (ATCC 6538), a Gram-positive bacterium, and K. pneumonia (ATCC 4352), a Gram-negative bacterium. The blended high-loft nonwoven fabrics, apart from the control blend number 5, had high LOI values greater than 24.7. Samples should have a higher LOI value than the threshold value of 20.95. All the blended high-loft nonwoven fabrics passed the vertical flame test and the char length increased with the decrease in the proportion of the SRRC FR cotton in the blends. The blended high-loft nonwoven fabrics were effective in reducing the bacteria by 99.9% for both types of bacteria tested. FR gray cotton fiber obtained from the treatment of SRRC 2 formulation (blend number 4) also showed good antibacterial properties.

In this article, the effects of fabric weight, fiber cross-sectional shapes (round, hollow, and trilobal), and presence of reinforcing material on the compression properties (initial thickness, percentage compression, percentage thickness loss, and percentage compression resilience) under dry and wet conditions of polyester needle-punched industrial nonwoven fabrics are presented. It has been found that initial thickness of the fabric decreases under wet condition for both with and without reinforcing materials. The percentage thickness loss values are higher under wet condition in case of samples with reinforcing material compared to samples without reinforcing material. In the presence of reinforcing material, the trilobal cross-sectional fabric samples show the highest increase in thickness loss under wet condition followed by round and hollow cross-sectional polyester needle-punched nonwoven samples. Compression resilience is the highest in case of round cross-sectional fabric without reinforcing material under wet condition than fabric with reinforcing material. The initial thickness increases, and percentage compression and thickness loss decrease with the increase in fabric weight irrespective of fiber cross-sectional shapes both in dry and wet conditions. The initial thickness, percentage compression, and percentage compression resilience of the fabric decrease but percentage thickness loss increases under wet condition compared to the dry condition irrespective of the fiber cross-sectional shape. Compared to other cross-sectioned polyester samples, the hollow cross-section samples undergo very less consolidation under wet condition due to their consolidated structure. There is a drastic drop in compression resilience and increase in thickness loss under wet condition than in dry state irrespective of the fiber cross-sectional shape.

The growth of microbes on textiles inflicts a range of unpleasant effects not only on thetextile itself but also on the wearer. The detrimental effects can be controlled by antimicrobial finishing of textile using Sanitized T99-19 in the finishing formulation andsimulated curing/transfer printing in one step for different types of fabrics. Improvements of multifunctional property vary, to some extent with the nature of fibrous substrates, resin concentration, simultaneous curing/transfer printing, temperature employed, and various additives in the finishing formulation used to affect the polymerization of the reactant. Optimized resin concentrations as well as transfer printing temperatures to enhance the properties of the finished fabrics were reported. Quantitative analysis was carried out to measure antibacterial activity against Gram-positive and Gram-negative bacteria. The results showed that printed fabrics inhibited the growth of both Gram-positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli) bacteria compared with control samples (without Sanitized T99-19). Improvement of color strength as well crease recovery angle was obtained. Antibacterial activity was retained up to 20 cycles. Scanning electron microscopy of finished fabrics was performed.

In this article, various approaches are investigated and synthesized for real-time inspection of diversified fabric texture. Improved Gabor filter bank was proposed to detect fabric defects by using its property of steerable directions and scales. Normal fabric textured image was processed with optimal filter and then gauss smooth. Two threshold value of thenormal fabric image will be determined, which are considered as standard of image parameter for segmenting defect areas. For some intense background texture of fabric defect images, background analysis approach is proposed to detect the flaws. The third detection method is multi-scale wavelet, and typical results of the test are provided. Threeapproaches synthesized into a cascade detection system to develop better detection results. Inspection results that conducted on real fabric defects for various approaches reveal that combined detection scheme meet good expectation. Further, preliminary graphical user interface is designed so as to facilitate the operation. After integrate graphical user interface with procedure, parameters material can be acquired, which is vital to applying the inspection system on industrial computer in future.

In this article, a numerical method to predict textile geometry is derived using a technique based on finite elements (FEs). A geometric modeling package is used to represent an initial geometry of the yarns within the textile. The yarn mid-surface is then represented using plate elements, with the yarn thickness and cross-section being reconstructed from this mid-surface. The bending and tensile aspects of the yarn behavior are represented by separate features of the plate elements and the total energy for the system is minimized. Contacts are modeled using a penalty method, where the contact force is proportional to penetration distance. Once geometry correction has been achieved by solving the FE problem, the geometric model of the textile is corrected to take into account the predicted movements of the yarns. For validation purposes, the method is applied to two-dimensional (2D) and three-dimensional (3D) weaves and compared against images of the real fabrics. Agreement between predictions and images is good for the 3D weave and excellent for the 2D weave.
