Abstract


Analysis of dynamic elastic behaviour is an objective evaluation of the stretch and recovery behaviour of the elastic fabrics or tight fit garments. The analysis of this dynamics will help to reengineer new products for improving the stamina, speed and power of the sportsmen, as one particular type of garment doesn’t serve the purpose of all kinds of sports events. The study is to analyse the effect of spandex input tension, spandex linear density and cotton yarn loop length on dynamic work recovery of cotton / spandex single jersey knitted fabric. The effect of different processing stages such as relaxation, heat setting, bleaching and compacting on dynamic work recovery of cotton / spandex single jersey knitted fabric has also been analysed in this study. Effect of different stages of processing on DWR of the fabric has significant influence. The effect of spandex input tension and cotton yarn loop length on DWR of the fabric have been significant in any one direction. The effect of spandex linear density on DWR of the fabric has been significant at both walewise and coursewise directions.
