Title: Ecofriendly antimicrobial finishing of textiles using bioactive agents based on natural products Authors: Joshi, M; Ali, S Wazed; Purwar, R; Rajendran, S Abstract: In the present scenario of environmental consciousness, the new quality requirements not only emphasize on the intrinsic functionality and long service life of the product but also a production process that is environment-friendly. Therefore, research on environment-friendly antimicrobial agents based on natural products for textile application is gaining worldwide interest. This paper reports a comprehensive review on natural product based bioactive agents such as chitosan, natural dyes, neem extract and other herbal products for antimicrobial finishing of textile substrates. Different classes of active ingredients found in extracts of natural products and their mechanism of antimicrobial action have been presented. The major challenges and the future potential of application of natural products on textiles have also been critically reviewed Page(s): 295-304

Title: Yarn structure - properties relationship Authors: Basu, Arindam Abstract: Yarn structure and its relationship with the properties have attracted many researchers and scientists. This has resulted in a large number of published research works scattered in many places. The importance of this subject has increased due to the need of yarn with best possible quality at optimum cost. Also, the diversification of textiles in various products, such as technical textiles, where performance is the main criteria, necessitated better yarn engineering. An attempt has been made to analyse the study reported in this subject area Page(s): 287-294

Title: Suitability of modified method for evaluating low-stress mechanical properties of silk fabrics Authors: Radhalakshmi, Y C; Somashekar, T H; Subramanium, V Abstract: Modifications have been made to the simple conventional method of determining low- stress mechanical properties of fabrics to make it applicable for finished silk fabrics.  The bending rigidity of the fabrics has been obtained from the tensile stress-strain curves and shear rigidity by bias extension.  The correlation between the parameters obtained by the modified method and that obtained by the Kawabata evaluation test method is found to be good for a series of finished silk fabrics Page(s): 283-286

Title: New dyeing technique for enhancing colour strength and fastness properties of cotton fabric dyed with natural dyes Authors: Mahangade, R R; Varadarajan, P V; Verma, J K; Bosco, H Abstract: Dyeing behaviour of four different natural dyes extracted from the leaves collected in a sustainable manner from respective dye containing plants has been studied on cotton fabric. A novel and ecofriendly mordanting technique has been devised for creating aluminium-tannate complex on cotton matrix. The new mordanting technique not only involves application of a modified sequence of mordanting chemicals but also employs addition of specific salts in water used in the dyeing process. The dyeing of the mordanted fabric has been carried out under acidic and alkaline conditions at different temperatures. The modified dyeing technique shows an overall improvement of 140-300% in colour strength along with the excellent fastness properties, such as washing, rubbing, perspiration and light. The overall results indicate that all the four natural dyes can be effectively and economically used for dyeing on cotton fabric. The entire chain of collection, extraction and dyeing methodology is environmentally and ecologically compatible Page(s): 279-282
