Abstract
Twist is an important factor for the strength of yarn as well as the end product. Generally, higher the twist of the yarn higher the strength of the yarn. But twist has to be an optimum value. If the twist increases up to the optimum value, after this point the strength of yarn will reduce although the twist is increased. A study was performed on the physico- mechanical and physico-chemical properties of jute: acrylic blended sweater and 100% acrylic sweater made from different ( 3 to 6 TPI ) twisted yarn. It is observed that blended sweater made from the twist 3 TPI, 5 TPI and 6 TPI shows dissimilar properties to the 100% acrylic sweater prepared from similar type of yarn. But sweater made from the yarn of 4 TPI shows very acceptable results which are nearer to the properties of 100% acrylic sweater. Hence, 4 TPI is a suitable twist to produce standard sweater.
