Abstract:

In order to study calculating fitness of elastic knitted clothing, 20 types of elastic knitted fabrics were selected. First the force at 10%,20%,30%,40%,50% and 60% elongation and clothing pressure at 10%,20%,30%,40%,50% elongation were tested and analyzed respectively. Then correlation between the force at specified elongation of elastic knitted fabrics and clothing pressure，and between the force at specified elongation and elongation percentage of elastic knitted fabrics were analyzed. The results show that correlation between the force at specified elongation of elastic knitted fabrics and clothing pressure，and between the force at specified elongation and elongation percentage of elastic knitted fabrics are highly significant and linear regression is highly significant. The clothing fitness range of different elastic knitted fabric will be calculated by testing the force at specified elongation of elastic knitted fabrics, and by means of regression equation between the force at specified elongation of elastic knitted fabrics and clothing pressure，and between the force at specified elongation and elongation percentage of elastic knitted fabrics, and by means of regression equation between the elongation percentage of elastic knitted fabrics and the clothing fitness. The research results can provide theoretical basis and practical reference for rapid calculating fitness of elastic clothing and for the design and development of elastic clothing.
