300-307Elastane fibres
show rubber like behavior and are highly stretchable. 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
