Influence of tuck stitch in course direction on thermal comfort characteristics of layered knitted fabrics

Abstract

The thermal comfort characteristics of bi-layer knitted fabrics have been studied for shuttle badminton sportswear. Bi-layer knitted fabrics are developed by changing tuck position in course direction such as 6, 10, 14 and 18 course repeat, keeping the tuck on 12^th wale the same. It is observed that the greater the distance between successive tuck points, the better will be the air, heat and moisture transfer properties. Bi-layer knitted fabric with slack structure facilitates lower thickness and mass per unit area, and exhibits better thermal comfort characteristics. By wear trial method, bi-layer knitted fabric with tuck on 18^th course and 12^th wale shows good rating compared to other bi-layer knitted fabrics. The results are discussed at 95% significant level with ANOVA analysis and Friedman one-way analysis of variance.
