Basically these fibres contain polyurethane bonds. Elastic fabrics are an important route to achieve comfort by freedom of movement for body fitted with sports and outdoor wear. Elastic garments used in athletics and sports may improve the athlete’s performance in cycling, swimming and so on. A great deal of research is reported on elastane structure, yarn formation and fabric production. Testing of elastane and its fabric has given new dimensions in terms of results. New attempts are being made to produce the yarn with blends and subsequent conversion into woven and knits, in order to improve garment elastic bahaviour and productivity. This paper reports the elastane fibre characteristics, elastane yarn production method, new attempts in yarn production, commercial ways of fabric manufacturing techniques, fabric properties, new testing methods to test the elastic products and its application. <br/> <br/>Page(s): 300-307 Mon, 29 Aug 2011 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/12654 Title: Atmospheric pressure plasma treatment of textiles using non-polymerising gases <br/> <br/>Authors: Kale, Kiran H; Desai, A N <br/> <br/>Abstract: Surface modification of textiles by plasma treatment for imparting certain desired properties in terms of wettability, adhesion promotion, surface energy improvement and host of other characteristics has been the subjects of interest to researchers in the last few years. The plasma technology for textiles has emerged from conceptual embryonic stage to growth stage, where considerable research is yet to be carried out to translate the potential into industrial reality. This review aims at reporting the current status of the atmospheric pressure plasma technology in surface treatment of textiles, its effect on certain properties and the techniques used for characterisation of plasma-treated textile materials. The review paper also covers the studies carried out so far on the effect of atmospheric pressure plasma generated from non-polymerising gases like helium, argon, air, oxygen and nitrogen on the surface properties of both natural as well as synthetic textiles along with the changes in chemical and morphological characteristics of plasma-treated textile material using different qualitative and quantitative characterisation techniques, such as measurement of wicking height, contact angle, surface energy, SEM, AFM, FTIR and XPS. <br/> <br/>Page(s): 289-299 Mon, 29 Aug 2011 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/12653 Title: A novel method of yarn traversing suitable even for longer traverse lengths <br/> <br/>Authors: Koranne, Milind <br/> <br/>Abstract: Attempt has been made to develop a novel prototype yarn traversing mechanism for a filter winder to eliminate the use of grooved cam; especially to wind cylindrical packages of longer lengths such as PP/ glass wound filter cartridges. The novel yarn traversing mechanism is found to wind 762 mm (30 inch) long filter cartridges. The traversing mechanism mainly includes three yarn guides mounted on an endless chain passing over six sprockets with an arrangement of relieving yarn from one guide to the other at traverse extremes. Filter cartridges with various traverse ratios are precision wound on this winder with 0.4 hank and 0.6 hank polypropylene yarn. The new traversing mechanism is simple, cost effective and can be adopted to develop a filter winder of any length. <br/> <br/>Page(s): 285-288 Mon, 29 Aug 2011 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/12652 Title: Effect of composition of knitted fabrics on their cooling efficiency at simulated sweating <br/> <br/>Authors: Hes, Lubos; Ursache, Mariana <br/> <br/>Abstract: Cooling efficiency of selected underwear knits in the simulated condition of fabric wetting by means of single sweating pulse has been experimentally investigated. The method is based on non-traditional use of the small skin model Permetest with a very short time of measurement. Cooling efficiency has been calculated as the product of cooling heat flow and wet area after application of 0.5 mL of water on the fabric surface to simulate the sweating impulse. It is found that the highest cooling level is exhibited by the knitted fabrics containing polyester filaments with grooved surface, which conducts the liquid moisture along the fabric plane. <br/> <br/>Page(s): 281-284 Mon, 29 Aug 2011 22:58:59 GMT
