Problems solved by technology

The price of polyester dust-free cloth is favorable, but the dust removal effect is average, and the surface is rough and easy to scratch the surface of precision products
The polyester-nylon composite superfine fiber dust-free cloth has excellent absorption and dust removal performance, and the surface is fine and not easy to scratch the surface of precision products, but it is expensive, which greatly increases the cost of the product, so it has not been widely used.
[0003] In addition, the dust-free cloth produced by the current dust-free cloth production method often has defects in cleanliness, dust adsorption capacity, wear resistance and decontamination ability that cannot meet the requirements, and the production process is relatively cumbersome.

Abstract

The invention provides a method for preparing a blended ultra-fine dust-free cloth and the prepared dust-free cloth. The main steps include: mixing and weaving polyester yarns with a mass ratio of 1:2 and polyester nylon ultra-fine fiber yarns with a knitting machine Make gray cloth; put the gray cloth into the dyeing vat according to the bath ratio of 1:5~7; add penetrant, sodium hydroxide, EDTA-4Na, and degreaser into the dyeing vat; wash while washing, soak in acetic acid , wash again, then add detergent, and wash the gray cloth etc. again in the way of washing while washing. According to the preparation method of the blended superfine dust-free cloth provided by the invention, the prepared dust-free cloth not only has good characteristics such as wear resistance, cleanliness, and decontamination ability, but also effectively reduces costs and has a simple process flow.

Description

technical field [0001] The invention belongs to the field of dust-free cloths, and in particular relates to a dust-free cloth blended with polyester and polyester-nylon composite superfine fibers, which is used to replace conventional polyester-nylon composite superfine dust-free cloths in the industry. Background technique [0002] Dust-free cloth is a kind of chemical cloth widely used in electronic optical medical semiconductor equipment. It has high requirements for its own cleanliness, absorption, dust removal and wear resistance. At present, polyester dust-free cloth, Or a polyester-nylon composite ultra-fine dust-free cloth. The price of polyester dust-free cloth is favorable, but the dust removal effect is average, and the surface is rough and easy to scratch the surface of precision products. The polyester-nylon composite superfine fiber dust-free cloth has excellent absorption and dust removal performance, and its surface is delicate and difficult to scratch the s...
