Environmentally-friendly breathable microfiber synthetic leather structure and production process

Abstract

The invention discloses an environmentally-friendly breathable microfiber synthetic leather structure and a production process. The environmentally-friendly breathable microfiber synthetic leather structure comprises a synthetic leather main body; the synthetic leather main body mainly comprises a leather face layer and a basal layer; the leather face layer mainly comprises polyurethane semi-finished leather and a photocatalyst coating; and the basal layer comprises a plurality of layers of polytetrafluoroethylene films and a nylon fabric. According to the environmentally-friendly breathable microfiber synthetic leather structure and the production process, a primary backing fabric of the synthetic leather is made of a microporous polytetrafluoroethylene film and nylon fabric layer laminating composite material, so that the breathability of the primary backing fabric of the basal layer is improved; a certain dosage of polyethylene powder is added in surface layer PU (polyurethane) glueof the synthetic leather, so that the breathability of a leather face is improved; and meanwhile, the compact photocatalyst coating is sprayed on the surface layer of the leather face, and by means of the capacity of decomposing harmful substances by a photocatalyst, the environmental protection property of the synthetic leather is improved, and the application range of the synthetic leather is extended.

Description

technical field [0001] The invention relates to the field of synthetic leather manufacturing, in particular to an environment-friendly breathable superfiber synthetic leather structure and production process. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. It is usually made of impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. They are very similar to leather and have a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. Widely used in making shoes, boots, bags and ball games. [0003] Most of the current synthetic leather is to directly coat the rubber material on the pretreated base cloth with a scraper, then put it into the plasticizing box for gelation and plasticization, and then go through embossing, cooling and other processes to obtain th...

Problems solved by technology

[0003] Most of the current synthetic leather is to directly coat the rubber material on the pretreated base cloth with a scraper, then put it into the plasticizing box for gelation and plasticization, and then go through embossing, cooling and other processes to obtain the finished product; The synthetic leather produced first has poor air permeability of the leather surface and the base fabric, which limits the subsequent application of synthetic leather; in addition, synthetic leather is a chemical product, and various residues are prone to occur on the finished product, so it is not suitable for use in all environments
