Problems solved by technology

This method is a common processing method for polyester-cotton fabrics. This process cannot realize the processing of pure cotton or all-cotton fabrics at all. Because all-cotton fabrics are very sensitive to strong acids, strong alkalis and strong oxidants, they have strong moisture absorption. The existing technology has been unable to process and produce all-cotton fabrics with vapor-permeable (wet) anti-acid, alkali, solvent, oil, water, and chemical effects. It is urgent to study and improve the processing technology of cotton fabrics.
However, most of the chemical-resistant fabrics on the market adopt the processing method of coating and organic fluorine composite finishing. This method has poor air permeability and moisture permeability, stuffy and uncomfortable feeling when wearing, and cannot effectively protect chemical solvents, coatings and fabrics. Problems such as low bonding fastness

Abstract

The invention discloses a processing method for chemical-preventing fabric, and belongs to the technical field of textile industry. The method is carried out on the basis of gray fabric woven from pure cotton yarns or polyester cotton yarns, and comprises the processes of blank inspection, seam overturning, singeing, cold batching, short steaming, washing and dyeing. The method is characterized by also comprising the steps of A, open-width washing, B, chemical-preventing arrangement, C, preshrinking treatment, and D, baking. The chemical-preventing fabric processed by the method has a function of preventing sulfuric acid, hydrochloric acid, nitric acid and caustic soda, has a good function of preventing chemical solvents such as o-xylene, methyl alcohol and acetone, and meets an EN14325 chemical-preventing standard.

Description

technical field [0001] The invention belongs to the technical field of the textile industry, and relates to a processing method for cotton and polyester-cotton fabrics, in particular to a processing method for chemical-resistant fabrics. Background technique [0002] With the rapid development of the textile manufacturing industry and the improvement of people's living standards, consumers' requirements for environmental protection and health of fabrics are also constantly increasing. Strictly speaking, it is resistant to sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and Potassium hydroxide liquid and breathable textile fabrics are extremely rare, and cotton and polyester-cotton fabrics that can effectively prevent the wetting and penetration of solvents such as o-xylene liquid, methanol, and chloroform are even less reported. This type of fabric must not only meet GB12012-12013-89 "Acid-proof Work Clothes", GB12799-91 "Safety and Hygienic Performance Requi...
