Problems solved by technology

At present, synthetic leather is widely used in people's lives. The existing synthetic leather generally includes a surface layer and a middle layer. The surface layer is laminated on both sides of the middle layer. The surface layer is generally mixed with resin and various modifiers. The middle is generally a fiber layer, but the fit between the surface layers of such synthetic leather and between the surface layer and the middle layer is poor. After a period of use, the surface layer and the middle layer will split.

Abstract

The invention discloses penetrating-connection type synthetic leather and a preparation method thereof. The penetrating-connection type synthetic leather comprises a middle layer, an upper binding surface layer and a lower binding surface layer. A plurality of penetrating-connection holes are uniformly formed in the middle layer, so that the upper binding surface layer and the lower binding surface layer correspondingly penetrate into the penetrating-connection holes, and the grabbing force between the upper binding surface layer and the middle layer and between the lower binding surface layerand the middle layer is greatly enhanced.

Description

technical field [0001] The invention relates to a piercing type synthetic leather and a preparation method thereof. Background technique [0002] With the continuous development of society, people's living standards are improving day by day, and people's requirements for living environment are also increasing day by day. At present, synthetic leather is widely used in people's lives. The existing synthetic leather generally includes a surface layer and a middle layer. The surface layer is laminated on both sides of the middle layer. The surface layer is generally mixed with resin and various modifiers. The middle is generally a fiber layer, but the fit between the surface layers of such synthetic leather and between the surface layer and the middle layer is poor, and the drawback of splitting the surface layer and the middle layer will appear after a period of use. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the problem ...
