Quality optimization by evaluating physico-mechanical properties of industrial acid wash, cool dyeing and dip dyeing processes on knitted garment

Abstract

Industrial garment washing and garment dyeing are currently taking over fashion trends. At present, these processes are not only confined to woven garments but also applied over knitted garments. Nevertheless, prolonged washing time, use of different chemicals during the washing and dyeing procedure affects the physical and mechanical performance of the garment. This is ultimately affecting the quality of the finished garments and resulting in more fabric wastage during these treatments. In this study, industrial garment finishing processes like Acid wash, Cool Dyeing, Dip Dyeing process were applied on 100% Cotton Slub Single Jersey (160 GSM) knitted T-Shirt. The aim of this study is to determine the effects of industrial Acid washing and cool-dip dyeing on physico-mechanical properties of knitted garments. To evaluate the washing and dyeing effects, changes in fabric weight, changes in dimension, bursting strength, dry and wet rubbing fastness, color fastness to perspiration, pilling and washing tests were performed. Experimental data showed that GSM increased for Acid washed garment but dimension change, color fastness to washing, rubbing, bursting strength and perspiration decreases significantly in comparison with Cool and Dip dyeing.
