Natural colour cotton spinning treatment process

Abstract

The invention is a spinning technique of natural colour cotton, especially a blending technique of natural colour cotton and white cotton. First respectively make said colour and white cotton into cotton roll in clean-cotton opening procedure and respectively make the roll into crude strips in cotton-combining procedure; then make the color-cotton crude strips carry through one-step pre-combination and make the white-cotton crude ones into combining ones; then make pre-combining strips and combing ones into mixed wrough ones in strip-combining procedure; make the wrought strips into finished yarn product through the procedure of rough yarn, spun yarn and so on.
