A kind of preparation method of toilet cotton soft towel

Abstract

The present invention relates to the preparation technology of non-woven fabrics, in particular to a preparation method of toilet soft cotton towel, which comprises the following preparation steps: A, stock preparation: combed cotton linter fibers and combed cotton linter fibers Add water to mix and stir evenly, then add degreasing or degreasing bleaching agent to degrease or degrease and bleach the cotton fiber, send it to the filter system to screen out sand and impurities to obtain cotton cellulose pulp, and finally perform beating treatment on the cotton cellulose pulp B, preparation of fiber suspension: add a pH regulator to the fiber slurry after the beating treatment in step A, and simultaneously stir the fiber slurry to make the fiber slurry mix uniformly, and the pH value of the fiber slurry after mixing is uniform 5-7.5, then add water to prepare the fiber suspension of 0.005%-0.03% cotton fiber mass concentration; C, wet-laid; D, spunlace reinforcement; E, drying, the method adopts cotton fiber to prepare toilet cotton Soft towel, saving resources and environmental protection.

Description

Technical field[0001]The present invention relates to nonwoven fabric preparation techniques, and more particularly to a method of preparing to toilets.Background technique[0002]Can be toilet cotton scarves can act on people such as cleaning skin or cleaning toilet, which has tapability. After the use is completed, it can be directly put into the toilet. By moving with water flows and sewage tube movements and Degradation so that the pipe and the filter are not blocked.[0003]The materials used in most of the ink toilet non-woven fabric in the market are mainly bleached wood pulp fibers and bleached adhesive fibers, but the viscose fibers and wood pulp fibers have a large amount of acid, alkali waste fluid. And the viscose fiber production process also drains carbon sulfur hydrogen sulfide, hydrogen sulfide exhaust gas, and produces waste resides containing a large amount of sulfate sulfate and cellulose, not only largely waste resources and the sewage process also brings environment...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the non-woven fabrics used in the market are mainly bleached wood pulp fibers and bleached viscose fibers, but viscose fibers and wood pulp fibers will have a large amount of acid and alkali waste liquid during the production process. , and the viscose fiber production process will also emit carbon disulfide, hydrogen sulfide waste gas into the atmosphere, and produce a large amount of waste residue mixed with sulfuric acid sulfide and cellulose, which not only wastes resources to a large extent, but also brings environmental pollution during the sewage discharge process.
