Despite considerable interests that have been shown on the formation, properties and characteristics of auxetic knit structures there remains a dearth of information about the fundamental geometrical analytics of warp knit auxetic fabrics. This paper examines the geometrical model of auxetic warp knit structure and validates its characteristics with data obtained from experimental analysis of nine recently produced warp knit auxetic fabrics.

Textile dyeing industry effluents require advanced treatment technologies such as adsorption for the removal of dyestuffs. In this Study Chitosan Zinc Oxide Nano composite was used as an adsorbent for removal of sample that contains two reactive dyes: Reactive Black HN and Reactive Magenta HB from textile dying industry effluent. The color removal performance of Chitosan Zinc oxide Nanocomposite has been investigated using parameters such as temperature, composite loading, time of contact and turbidity. It was found that composite exhibits dye removal efficiency that is about 95-99%. Batch adsorption studies of color removal from effluents of Textile dyeing industry were carried out using Chitosan-zinc oxide Nano particles composite. Results showed that color adsorption increases with the increase of the dosage of composite. In this study, optimum dosage was found for the removal of dye from Textile effluents. It was found that using 2 gm of Composite per liter of effluent at ambient temperature (50°C) and 60 minutes time of contact, it may be possible to remove 99% of the original color of the effluent.

Traditional embroidery with ethnic designs and motifs in brilliant colors bear a distinct hallmark of Indian textile design. This embroidery has its own regional identity and has crossed borders to be marketed in different parts of the world. This paper discusses the efforts made by artisans to revive and modify the ‘kasuti’ embroidery designs to cater the consumers in international markets. The study identifies its key success factors in international markets both from retailer as well as artisan’s perspectives.

The process of diffusion polymerization in a mixed bath is used to produce the electrically resistant fabrics such as the polyester, polyester/viscose, viscose, Bamboo, Bamboo/cotton and cotton fabrics and it is done by the in situ chemical oxidative polymerization of conductive polyaniline (PANI) polymer having ammonium persulphate as the oxidant. The electrical resistance of the fabrics have been measured with the help of D.C. regulated variable power supply unit by varying the gauge length from 1”, 2” and 3” and input voltage from 20V to 160V. The polyaniline coating evenness was investigated by using Scanning Electron Microscopy (SEM). The test result shows that the electrical resistance decreases with increase in the gauge length and the input voltage and also fabric cover factorshave playing an important role on electrical resistance of the fabrics. The polyaniline coated cotton fabric has less electrical resistance than the polyaniline coated fabrics of the polyester, polyester/viscose, viscose, Bamboo, Bamboo/cotton. The cotton and cotton blend fabrics surface have absorbed more polyaniline particles and hence show more depositions over their surface when compared to that of bamboo, polyester, polyester/viscose and viscose.

In the current study, the single jersey knitted fabric from natural fibers bamboo (Dendrocalamus strictus), soybean (Glycine max) and flax (Linum usitatissimum) at various blend ratios are prepared for comparison of physical strength and antimicrobial properties. For the general characteristic evaluations it is deduced that the fiber strength of pure flax is comparatively stronger than bamboo and soybean, whereas the antimicrobial properties of the bamboo fibers are the highest. Therefore, the blended fabric with multiple compositions for these three fibers is prepared and compared with the fabric made from individual pure fibers. In sum, the blended fabrics showed enhanced results for both antibacterial activity and strength, where the strength of flax/bamboo blended fabric with equal ratios (50/50) at higher twists and antibacterial activity of soybean/bamboo blended fabric with blend ratio 10/90 was found the best as compared to other combinations.
