Problems solved by technology

If the acid resistance of the work clothes is poor, when it is corroded by acid liquid, it will corrode the work clothes to a certain extent, and may seriously corrode the employees.
Viscose fabric has good air permeability and humidity control function, but its acid resistance is not high, which limits its application range

Abstract

The invention discloses an acid-resisting finishing method for viscose fabric. The method comprises the following steps: a finishing agent is mixed with water to be made into an impregnation liquid, fabric is put into the impregnation liquid for padding, the pick-up rate is 45%-70%, finally, the fabric is washed with water twice or three times, and the viscose fabric can be obtained after water removal and drying. The finishing agent comprises components in parts by weight as follows: 20-50 parts of water, 6-9 parts of sodium polystyrene sulfonate, 5-6 parts of dimethyl terephthalate, 4-7 parts of ethylenediamine tetracetic acid disodium salt, 1-6 parts of acrylamide, 22-25 parts of butyl acetate, 5-8 parts of dimethylcydosiloxane, 3-7 parts of didecyl dimethyl ammonium chloride, 11-16 parts of an isocyanate trimer, 4-8 parts of methyl hydrogen silicone oil, 4-8 parts of o-hydroxybenzoic ester, 4-8 parts of vinyltriethoxysilane and 1-5 parts of fatty alcohol-polyoxyethylene ether. With the adoption of the acid-resisting finishing method, the viscose fabric can be prevented from being wetted and permeated by an acid liquid, can resist corrosion of strong acid and has the advantages of being breathable, comfortable, soft, light, easy to wash and the like.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to an acid-resistant finishing method for viscose fabrics. technical background [0002] Viscose fabric is a fabric woven from viscose fiber, which is one of the earliest chemical fibers put into industrial production. Because of its good hygroscopicity, comfortable wearing and excellent spinnability, it is often blended and interwoven with cotton, wool or various synthetic fibers for various clothing and decorative textiles. Viscose fiber is a widely used chemical fiber. It is made of alkali cellulose by alkalization of natural cellulose, and then reacted with carbon disulfide to generate cellulose xanthate. The viscous solution obtained by dissolving in dilute lye is called viscose. Glue and viscose are made into viscose fiber through wet spinning and a series of post-processing procedures. Viscose fiber has good hygroscopicity, and the moisture regain is about 13% ...
