Movement comfort is an important performance parameter for workwear fabric. The lower value of load developed in the fabric at a certain extension level indicates lower stress on the skin and easier body movement. After repeated usage, there is a possibility of degradation in this movement comfort due to abrasion and cyclic loading. Measurement of the probability of successful performance of the workwear fabric in terms of movement comfort during usage is possible through reliability analysis. The present study is concerned with the reliability analysis of the body movement comfort of the workwear fabric under abrasive damage. The effect of composition and structure of different types of stretch yarn, i.e. cotton core spun, polyester core spun and polyester multifilament air-covered yarn, on this reliability has been studied. It is seen that after repeated cyclic loading there is a degradation in the movement comfort of the fabrics. The extent of degradation depends on the composition of the stretch yarn. Although the workwear fabric with the elastane contained cotton core spun weft yarn showed lower abrasion resistance, it showed the best reliability values in terms of movement comfort. Abrasive damage resulted in improvement in the level of movement comfort at higher levels of loading cycles.
