Abstract
Textile materials generally pass through wet processes during pre-treatment, colouring and finishing operations. The process conditions and chemical and physical medium of a particular process are varied. Consequently, the dimensional stability of the fabrics exposed to heat and humidity depends on many factors. In this study, the contraction behaviour of woven wool fabrics in different structures are investigated with an analytical approach as they go through various wet processes. It is observed that the weave type and weft density parameters affect the contraction behaviour in weft and warp direction. The effect of hygral expansion in wool fibre stability is great. The fixation effect obtained through the decatizing of the wool fabrics as a pre-treatment operation, directly affects the hygral expansion rates and hence the dimensional stability behaviour of the fabric in subsequent wet processes.
