Method for producing pure cotton non-woven fabrics for life and hygiene

Abstract

The invention discloses a method for producing pure cotton non-woven fabrics for life and hygiene. The method is mainly characterized by comprising the steps of carding cotton, enabling cotton fiber to conduct single fibrillating to the greatest extent, cleaning up dust and cotton flocks in the cotton, and carding the cotton to form a fiber web; conducting reciprocating cross laying on the fiber web to form a thick fiber web in the 45-degree direction, again conducing traction, after conducting stretching, evenness and orderliness on the thick fiber web, utilizing high-pressure water flow to conduct three-level spunlace on the thick fiber web so as to enable the thick fiber web to be wound, then again utilizing a synchronous scouring and bleaching method, conducting single function producing, such as synchronously conducting bleaching, degreasing and dyeing, also just conducting bleaching without degreasing or just conducting degreasing without bleaching, completing the production procedure of the pure cotton non-woven fabrics, finally enabling the pure cotton non-woven fabrics to be dried, and conducting curling. The method not only saves time, labor, manpower and cost, but also effectively ensures production quality, shortens the process route, improves process efficiency and reduces production cost. The method is an ideal and stable pure cotton non-woven fabric production technology.

Description

technical field [0001] The invention relates to a production method of a nonwoven fabric, in particular to a production method of a pure cotton nonwoven fabric for daily life and sanitation. Background technique [0002] A kind of invention patent has been disclosed in the Chinese Patent Gazette, its patent number is 200510033147.1 and its title is "Production Method of Cotton Non-woven Medical Dressing". Mesh - spunlace - degreasing - bleaching - finished coiling. Although this production method only goes through one degreasing-bleaching of cotton, the production cost can be reduced, and the impurity removal work is automated, which can effectively improve production efficiency and ensure product hygiene. However, its degreasing and bleaching process must be carried out twice in the order of degreasing-bleaching. Like this, not only water is much, causes waste, and degreasing, bleaching process time is longer, and work efficiency is lower. Contents of the invention [...

Problems solved by technology

In this way, not only is there a lot of water, resulting in waste, but also the degreasing and bleaching process takes a long time and the work efficiency is low.
