Problems solved by technology

However, the use of polyester-nylon composite fibers to prepare dust-free cloths, and the use of conventional alkali-treated fiber-opening processes in the preparation process to open the fibers, the dust-free cloths made can be used in general dust removal and cleaning processes, but still It cannot meet the strict dust-free environment requirements required in the production process of LSI and LCD products, and is slightly insufficient in terms of fiber opening degree, dust removal and pollution removal capabilities, etc. Most companies still choose to import from abroad

Abstract

The invention provides a production method of dustless cloth with high shrinkage and high dust removing efficiency as well as the produced dustless cloth. The production method comprises the following main steps: polyester / nylon superfine fiber yarns are woven to gray cloth by using a knitting machine; the gram weight of the produced gray cloth is 130-180 g / m2; the gray cloth is poured in a dye vat by the bath ratio of 1: 5-7; penetrating agent, sodium hydroxide, EDTA-4Na and degreasing agent are added in the dye vat; the gray cloth is cleaned in a manner of discharging while washing; acetic acid is added for cleaning again; splitting agent is added for treating, and the cleaning is performed; soaping agent is added; and the gray cloth is cleaned again in the manner of discharging while washing. According to the production method of the dustless cloth with high shrinkage and high dust removing efficiency provided by the invention, the produced dustless cloth has excellent absorbability and good dust and dirt removing effect.

Description

technical field [0001] The invention belongs to the field of dust-free cloths, and in particular relates to a production method for preparing dust-free cloths by using polyester-nylon composite superfine fiber filaments. Background technique [0002] Dust-free cloth is a kind of chemical cloth widely used in electronic optical medical semiconductor equipment. It has high requirements on its own absorption and dust removal. Fiber dust-free cloth is chosen by more companies. Polyester-nylon composite fiber is a kind of composite fiber produced by composite spinning technology. Polyester-nylon composite fiber becomes superfine fiber after opening. Composite fiber opening is divided into physical opening method and chemical opening method, and physical opening method is divided into mechanical method and heat treatment method; chemical opening method is divided into acid treatment method, alkali treatment method and organic solvent method. Mainly by alkali treatment. However,...
