Embodiment 2

[0041] A yarn pretreatment process, the yarn is made of cotton and polyester mixed, characterized in that after the cotton is cleaned and carded, it is prepared with polyester through drawing, roving, spun yarn, post-processing, and soaking processes, including Follow the steps below:

[0042] a: Cotton sliver making: select kapok fibers for cleaning, primary opening, blending, secondary opening, impurity removal and carding to obtain combed sliver;

[0043] b: made of polyester strips;

[0044] c: drawing: combine the combed sliver obtained in step a with the polyester sliver obtained in step b, including six cotton slivers and one polyester sliver to obtain a mixed cotton sliver, after stretching the fibers are straightened and parallel ;

[0045] d: multiple drawing: combine six mixed slivers obtained in the previous step with a polyester sliver again to obtain a new mixed sliver, and draw it;

[0046] e: Completion of drawing: Repeat the above steps until the six polyes...

Abstract

The invention discloses a yarn pretreatment process; yarns are prepared by mixing cotton and polyester; cotton is cleaned and combed, and then the cotton and polyester are subjected to drawing beforeroving, spinning, post-processing and soaking processes. The yarn pretreatment process comprises: manufacturing cotton slivers, to be specific, choosing kapok fibers for carrying out processes of cleaning, primary opening, mixing, secondary opening, cleaning and carding to obtain combed cotton slivers; manufacturing polyester slivers; drawing; carrying out multiple drawing, to be specific, combining the six mixed cotton slivers obtained in the previous step with one polyester sliver again to obtain a new mixed cotton sliver, and drafting; carrying out roving and spinning; and carrying out post-processing, to be specific, double-twisting primary blended yarns, and carrying out covering to obtain secondary blended yarns. The problem that mixing of the polyester yarns and the cotton yarns isnot uniform is solved.

Description

technical field [0001] The invention relates to a mixed yarn treatment process, in particular to a yarn pretreatment process. Background technique [0002] The biggest advantage of cotton fiber is its spinnability. The natural twist makes the cotton fiber have a certain wrapping force, which is beneficial to the spinning process. Cotton fiber has good hygroscopicity, warmth retention and wear resistance, and the moisture regain rate reaches 8.5%. It has no static electricity, good moisture absorption and perspiration, and is relatively close to the human body. The clothes made of it are comfortable to wear and have no pilling phenomenon. , soft to the touch; alkali resistance is not acid resistance, excellent alkali resistance, generally without any damage; cotton has excellent dyeing performance, easy to dye; under humidity, the strength of cotton fiber will increase by 10%, but the humidity is too high When low, the strength is poor. Cotton blending makes the fabric have...
