COMPOSITION OF CARBOHYDRATES IN FRESH WHEY — Proceeding R-1

Abstract

Synthesized in the 1890s and defined as a fiber containing a minimum of 85% acrylonitrile molecules by weight, acrylic fiber is primarily used in the clothing industry, in apparel products such as sweaters, dresses, suits and children’s clothing. Acrylic fibers are similar to wool in terms of high elongation and elastic recovery. These elastic properties ensure that fabrics made from acrylic and wool have a soft handle. High-bulk acrylic yarn is used for hand knitting yarn due to the soft touch. It is produced by blending relax and un-relax acrylic fiber in specific proportions and spinning them into yarn. The relaxation properties of acrylic fiber are affected by tow breaking process parameters. There are 3 main effective process parameters in the tow breaking process, including oven temperature, draw ratio and breaking tension. In this study, the effect of draw ratio on the properties of acrylic yarn in the tow breaking process was investigated. According to the results, draw ratio affected hairiness and unevenness in relaxed acrylic yarns,whereas tensile strenght and softness were unaffected.

Keywords: tow breaking process, high-bulk acrylic yarn, relax and un-relax acrylic fiber, temperature, draw ratio
