Problems solved by technology
[0002] At present, due to the wide range of uses of leather, such as shoes and boots, furniture, bags and so on, all kinds of leather are used in large quantities. However, the protection of animals in the world is increasingly strengthened, and the production of natural leather is more serious for environmental pollution.
The PU synthetic leather currently on the market includes the base fabric layer, the foam layer and the PU surface layer. The products made of this PU synthetic leather are not resistant to stretching during use and have relatively single functions.

Abstract
The invention discloses PU synthetic leather, which comprises a base cloth layer, wherein a polyurethane layer is arranged on the lower surface of the base cloth layer; an arc-shaped bulge is arrangedat one side, positioned the polyurethane layer, of the base cloth layer; an arc-shaped groove matched and connected with the arc-shaped bulge is formed in the polyurethane layer; an adsorption layeris arranged on the upper surface of the base cloth layer; a foaming layer is arranged on the upper surface of the adsorption layer; a metal net layer is arranged on the upper surface of the foaming layer; a PU surface layer is arranged on the upper surface of the metal net layer; negative ions are arranged inside the adsorption layer. Through the arrangement of the metal net layer, the tensile performance of the PU synthetic leather is enhanced; through the arrangement of the adsorption layer, harmful gas in the air can be adsorbed; harm to the human body caused by gas radiated out by the synthetic leather can be avoided.
Description
technical field [0001] The invention relates to the technical field of synthetic leather, in particular to PU synthetic leather. Background technique [0002] At present, due to the wide range of uses of leather, such as shoe making, furniture making, luggage making, etc., all kinds of leather are used in large quantities. However, the protection of animals in the world is increasingly strengthened, and the production of natural leather is more serious for environmental pollution. . The PU synthetic leather currently on the market includes a base fabric layer, a foam layer and a PU surface layer. The products produced by using the PU synthetic leather are not resistant to stretching during use, and their functions are relatively single. Contents of the invention [0003] The purpose of the present invention is to provide a kind of PU synthetic leather, to solve the problems in the prior art. [0004] In order to achieve the above object, the present invention provides th...
