Production method of pre-degreasing-bleaching high-speed high-yield all-cotton spunlace non-woven fabric

Abstract

The invention discloses a production method of pre-degreasing-bleaching high-speed high-yield all-cotton spunlace non-woven fabric. The method comprises a raw cotton degreasing and bleaching process and a spunlace non-woven fabric production process, wherein the raw cotton degreasing and bleaching process comprises the steps of opening, combing, cake making, degreasing and bleaching, dewatering, wet opening, drying, packaging and the like which are carried out in sequence, and the spunlace non-woven fabric production process adopts degreased and bleached cotton prepared through the raw cottondegreasing and bleaching process for producing the spunlace non-woven fabric, and comprises the procedures of opening and mixing, carding, net forming, spunlace, drying, coiling, slitting and the likewhich are carried out in sequence. The method has the beneficial effects that raw cotton is firstly manufactured into degreased and bleached all-cotton through the degreasing and bleaching process, then the degreased and bleached all-cotton is manufactured into the spunlace non-woven fabric, in the production process, the spunlace non-woven fabric has the advantages of being wide in breadth, highin vehicle speed, high in productivity, few in neps, good in product quality and the like, the labor cost can be effectively reduced, the production efficiency is improved, and the production cost isreduced.

Description

technical field [0001] The invention relates to the technical field of production of spunlace non-woven fabrics, in particular to a production method of pre-bleaching high-speed and high-yield cotton spunlace non-woven fabrics. Background technique [0002] Spunlace non-woven fabric is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber web is reinforced and has a certain strength, and the obtained fabric is spunlace non-woven fabric. [0003] Its fiber raw materials come from a wide range of sources, which can be polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. Cotton spunlace non-woven fabric has the characteristics of soft hand, fluffy and high hygroscopicity, and can be used for surgical cover cloth, medical dressing material, wound dressing, medical gauze, aviation rag, clothing lining clo...

AI Technical Summary

Problems solved by technology

[0004] The existing production process of cotton spunlace non-woven fabrics has slow production speed, narrow width, low production capacity, high labor costs and low work efficiency, which makes the production cost of cotton non-woven fabrics relatively high.
