Abstract:

In this study, the physical and dimensional properties of single jersey fabrics made from cotton / elastomeric core spun yarn were investigated. The main purpose of this paper was to investigate the suitability of cotton - spandex core spun yarn for circular knitting as an alternative for bare spandex feeding and the effect of stitch length variables on knitted fabric geometric quality attributes such as wale density, course density, stitch density and areal density under different states of relaxation. The results clearly indicate that the resulting yarn is highly suitable for circular knitting and change in stitch length values does not have any significant impact on wale density values. At the same time, the remaining geometric properties of the samples were found to be inversely proportional to the stitch length values uniformly at all the states of relaxation. Along with this, the ability of the samples to reach the dimensional equilibrium state after repeated cycles of washing and drying was also studied. It is evident from the results that all the three samples produced with ascending stitch length orders attained a perfect state of dimensional stability before five cycles of washing and drying, and also the sample knitted with the smallest stitch length value reached its equilibrium state in a quick time.
