Cotton-like Polyester Yarn with Soft Touch and Optimal Stiffness and Method of Preparing Same

摘要

The cotton polyester fibers according to the present invention can be produced by using at least two kinds of polymers, a POY (Partially Oriented Yarn) spun at a speed of 2,000 ~ 4,500 m / min through a nozzle having a split sectional shape or a godet roller in a spinning process, (POY or SDY) is twisted at a specific twisting temperature and tension in a twisted zone so that a twist is partially formed on the twisted yarn, and the twisted yarn (POY or SDY) ), The non-stretch heat treatment is performed to stabilize the shape, thereby manufacturing the false construction. After the fabric or knitted product is manufactured, the split ratio of the unfused portion in which the twist is not formed is reduced by 70% to 100%, the split ratio of the twisted portion is 0% to 70% by weight reduction or friction, And the like.
