Embodiment Construction

[0019] Describe concrete processing step of the present invention in detail below in conjunction with process flow chart:

[0020] 1. Carding: Under the environmental conditions of temperature between 15°C-25°C, relative humidity between 15°-70°, and equipped with a dust removal system, the prepared cotton is carded with an opening and cleaning machine and a carding machine , open the cotton bundles to make single fibers; and remove the impurities and short fibers in the raw cotton, the removal efficiency can reach 95%-99%, and finally the impurities in the carding sliver are only 0.05%-0.3% Then, the cotton fibers are mixed and carded, and the cotton fibers are mixed longitudinally along the cotton flow in the process of coagulating the cotton fibers in the doffer, and then the cotton fibers are mixed horizontally along the cotton flow in the process of forming a web, and finally carded to allow the cotton fibers The fiber web is arranged and positioned along the direction. ...

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 [...
