Mercerized yarn, pulp-free woven fabric and production methods of mercerized yarn and pulp-free woven fabric

Abstract

The invention relates to a mercerized yarn, a pulp-free woven fabric and production methods of the mercerized yarn and the pulp-free woven fabric, and provides a method for starching and weaving a warp by singed, mercerized and colored mercerized cotton yarn instead of the traditional pure cotton. A special mercerizing process is adopted, so the effects that mercerizing is more sufficient, the luster is brighter and the size stability is more excellent can be achieved; the fabric does not need singeing or mercerizing in a finishing process; the process flow is shortened; the production efficiency is improved, and the investment in production equipment is saved. The yarn prepared by the special mercerizing process is adopted, so complicated starching and destarching procedures in production of the woven fabric are reduced; the finishing procedure is reduced when sewage discharge is reduced and water resource is saved; the traditional fabric singeing and mercerizing procedures are omitted, and the variety of the fabric is certainly improved.

Description

technical field [0001] The invention relates to a production method of mercerized yarn and woven fabric, in particular to a size-free woven fabric whose warp yarn is cotton and its blended yarn of mercerized natural color or colored yarn and a processing method thereof. Background technique [0002] The process of the yarn passing through the high-temperature burner at high speed to burn off the excess fluff on the surface is called yarn singeing. The yarn surface after singeing requires smooth and uniform hairiness, and no obvious damage to the strength. Mercerizing means that the yarn is subjected to a certain tension under the action of a strong alkali to cause irreversible swelling. After mercerizing, the internal arrangement structure of the fibers undergoes a permanent change, the arrangement is more orderly, the degree of orientation tends to be consistent, and the strength of the fibers The dyeing and gloss are greatly improved, the depth of dyeing is greatly improve...

Problems solved by technology

[0003] However, the patent ZL200810194777.0 "a size-free shirt fabric with cotton warp thread and its production method" only involves the size-free weaving of mercerized cotton natural color yarn on woven shirt fabric with cotton warp yarn, and does not involve dyed yarn As well as the size-free weaving of cotton-containing blended materials, at the same time, the traditional processes of singeing, mercerizing, shaping and pre-shrinking are also required in the finishing, and the scope of application is limited.
