Abstract
The dynamic elastic behavior such as dynamic work recovery and stress at specific extension of the fabrics helps to analyze the instant garment response to body movements. It is an objective evaluation of the performance of the elastic fabrics for tight fit sportswear. The aim of the study was to compare the dynamic elastic behavior of cotton/ spandex fabrics with 100% cotton fabrics, since it is mandatory to know the level of performance of the cotton/spandex fabrics as compared with normal cotton fabrics with respect to energy gain or work recovery by the fabric which is necessary in evaluating the performance of the garment for specific sports application. It was found that the cotton/spandex fabrics have higher dynamic work recovery and lower stress value than those of cotton fabrics for both walewise and coursewise directions. The predictions of dynamic work recovery and stress values for different extension levels were made using a regression model.
