Abstract

Double-core yarn is made from short fibers as the outer wrapping material, with two different types of long fibers as core yarns twisted together. Due to the different properties of the two core yarns, a strong complementarity is created, giving the yarn superior characteristics. For example, cotton-wrapped T400 + spandex. The characteristics of T400 are: good bulkiness.

Double-core yarn is made from short fibers as the outer wrapping material, with two different types of long fibers as the core yarns twisted together. Due to the different properties of the two core yarns, a strong complementarity is created, giving the yarn superior characteristics. For example, cotton-wrapped T400 + spandex. The characteristics of T400 are: good bulkiness, excellent elastic recovery, better dimensional stability than spandex, and higher strength. It can also withstand repeated stretching. The characteristics of these two types of long fibers as core yarns, wrapped with cotton fibers, provide higher strength, abrasion resistance, good moisture absorption, softness, and elasticity. The yarn produced not only maintains the comfort of cotton and spandex but also has high abrasion resistance and tear strength, providing no sense of restriction, no pressure, and good dimensional stability when worn. The fabric produced with this yarn has a small shrinkage rate and good shape retention.
