Manufacturing method for hydrolysis-resistant clothing leather

Abstract

The invention discloses a manufacturing method for hydrolysis-resistant clothing leather. The method comprises the steps of mixing 5-10 kg of dimethyl formamide and 0.5-2 kg color paste uniformly; filtering the mixture; adding 100-120 kg of dimethyl formamide and 20-30 kg of wood powder to the above mixture, stirring uniformly and swelling; adding 100 kg of a polyurethane wet resin, stirring uniformly, defoaming and coating the obtained mixture on the textile fabric fiber; immersing in a solution of 18-22% dimethyl formamide to make the mixture solidified, squeezing water, washing with water and drying to obtain a wet base; mixing 100 kg of polyurethane dry resin, 10-20 kg of dimethyl formamide, 10-15 kg of butanone, 15-20 kg of toluene, 0.5-1.0 kg of an auxiliary agent and 3-5 kg of a toner uniformly and coating the obtained mixture on release paper to obtain a dry veneer; adhering the wet base to the dry veneer, drying, separating from the release paper, washing with a water graining machine and drying. The obtained product has the effects of hydrolysis resistance, cold resistance and folding resistance, and can effectively prolong service life of the leather.

Description

technical field [0001] The invention relates to a manufacturing method of artificial leather, in particular to a manufacturing method of hydrolysis-resistant garment leather. Background technique [0002] Artificial leather materials are often used in clothing. Because the artificial leather repeatedly wrinkles and rubs when the clothing is worn, it often leads to breakage and cracks in the artificial leather. Especially in low temperature seasons and regions, artificial leather is more prone to breakage and cracks. When artificial leather is stained with alkaline substances, it is also prone to hydrolysis, resulting in damage to clothing, scrapping, and short wearing time. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for producing hydrolysis-resistant garment leather. The process for producing hydrolysis-resistant garment leather is simple, and the product produced is resistant to cold, foldin...
