Patent ID: 7926253

Claim:
A method of making a textile product, comprising the steps of: first-steaming a first fiber bundle consisting of natural wool fibers; twisting the first fiber bundle after the first-steaming step so that the first fiber bundle has a twist of 30 turns per meter; second-steaming the first fiber bundle after the twisting step; drawing the first fiber bundle through a drawing device after the second-steaming step; third-steaming the first fiber bundle which has been drawn; untwisting the first fiber bundle by a reverse-twisting process after the third-steaming step; producing long hollow polypropylene filaments through a spinneret; drawing the polypropylene filaments through three rollers rotating at different speeds; heating the polypropylene filaments which have been drawn through an oven having a temperature of 100° C.; crimping, after the heating step, the polypropylene filaments in a stuffer box crimper, followed by heating and shape-setting the same in an oven having a temperature of 120° C.; cutting the polypropylene filaments which have been shape-set into staple fibers, followed by forming the staple fibers into a second fiber bundle; mixing the untwisted first fiber bundle and the second fiber bundle to obtain a fiber blend; and spinning the fiber blend to form a yarn.
