Embodiment 1

[0014] A kind of polyurethane slurry for producing PU peeling leather fabric described in this embodiment, each component is according to the mass ratio as follows: hydrolysis-resistant polyurethane: 100 parts; Dimethylamide: 5 parts; Butanone: 20 parts; toluene: 18 parts; deionized water: 20 parts; N-methylethanolamine: 1 part; sodium diisoester octane sulfonate: 3 parts; dye paste: 5 parts.

[0015] The production process of the above-mentioned polyurethane slurry includes the following steps: hydrolysis-resistant polyurethane: 100 parts, dimethylamide: 5 parts, butanone: 20 parts; toluene: 18 parts, deionized water: 20 parts; N- Methylethanolamine: 1 part; Sodium butene dioic acid diisoester octane sulfonate: 3 parts; Dye paste: Mix 5 parts by mass to form a mixed solution, fully stir for 2 to 3 hours, and stir until the viscosity of the slurry reaches 5000Pa .s or more, then filter. After the filter is completed, let it stand for more than 8 hours to be used as a fabric sl...

Embodiment 2

[0019] A kind of polyurethane slurry for producing PU peeling leather fabric described in this embodiment, each component is proportioned according to mass parts as follows: hydrolysis-resistant polyurethane: 100 parts; Dimethylamide: 7 parts; Butanone: 20 parts; toluene: 20 parts; deionized water: 20 parts; N-methylethanolamine: 1 part; sodium diisoester octane sulfonate: 3 parts; dye paste: 7 parts.

Abstract

The invention discloses polyurethane slurry for producing a PU (Polyurethane) stripped fur shell fabric. The polyurethane slurry is prepared from the following components in parts by weight: 100 parts of hydrolysis-resistant polyurethane, 5-7 parts of dimethyl acryl methylamine, 20 parts of butanone, 18-20 parts of toluene, 20 parts of deionized water, 1 part of N-methyl ethanol amine, 3 parts of di-iso-octyl maleate sodium sulfonate and 5-7 parts of dye paste. The coating shell fabric formed by the polyurethane slurry is uniform in micropore, and the polyurethane slurry is not easy to swell with water, thereby improving the water vapor permeability of the fabric. In addition, the polyurethane slurry can be freely colored, and the physical indexes such as color fastness, degree of sunlight, peel strength and tear strength can be randomly improved according to the demands of customers. The polyurethane slurry is free from extraneous odor, light in weight, less in possibility of hardening with water, perspiring, antibacterial and mildew-proof, and meets the environmental requirements.

Description

[0001] technical field [0002] The invention relates to a slurry used in the production process of fabrics, in particular to a polyurethane slurry used for producing PU peeling leather fabrics. [0003] Background technique [0004] With the development of the economy, people's living standards are getting higher and higher, people's requirements for the quality of life are gradually improving, and the demand for leather products is increasing, and the grade is also getting higher and higher. Our country has a large population and few resources, and the source of leather is limited, so it is difficult to meet the demand. In addition, people pay more and more attention to environmental protection. Green is synonymous with environmental protection, which requires the coexistence of economic development and sustainable production. The society pays more and more attention to sustainable development. Today, people have also begun to develop PU (polyurethane) peeling fabrics to...
