Bulked yarn

- Dec 08, 2018-

Bulked yarn: bulked yarn is a plump yarn with high softness processed by thermal shrinkage (thermoplasticity) of proline fibers. The low shrinkage and high shrinkage aliphatic fibers were blended into yarns in a certain proportion, and then the yarns were set by relaxation heat. In this way, the shrinkage of high shrinkage fibers is large, forming a yarn core, and the shrinkage of low shrinkage fibers is small.
