Abstract
In the present research, new methods of chemical relaxation have been studied for plain and rib weft knitted fabrics. Previous theoretical models presented maximum relaxation of weft knitted fabrics up to their stitch
density amount of 26.7 stitch/cm2
.Also previous relaxation methods of dry, wet, and chemical, mechanical and ultrasonic had processed fabrics up to 23.5 (stitch/cm2
). In this research various methods of chemical relaxations by using detergents, softeners, castification of 17% and 12% alkaline batches were compared with previous methods. Present research showed that chemical relaxation of fabric samples of cotton and blended fabrics could
be processed up to range of 26.2 to 26.6 (stitch/cm2
) by using cationic detergents. Also no damage on
yarns was occurred in using this detergent. on of 17% and 12% alkaline batches were compared with
