Problems solved by technology

[0003] However, most of the synthetic leather currently on the market has some problems, such as poor flexibility, poor wear resistance, unnatural wrinkle of synthetic leather, thick creases, poor resilience, and stiff hand feeling; 1. Affected by environmental conditions during use, mildew and bacterial growth often occur. In severe cases, not only waste raw materials, but also become an important source of disease transmission and endanger human health.

Abstract

The invention provides coarse-wrinkled thin-skin synthetic leather, and relates to the technical field of synthetic leather. The coarse-wrinkled thin-skin synthetic leather is composed of antibacterial base cloth, a thin-skin base layer and a texture layer from top to bottom in sequence. Compared with a traditional process, the synthetic leather prepared by the process has very natural skin wrinkling feeling, and the wrinkling feeling of the synthetic leather is similar to the wrinkling feeling of genuine leather; and on the other hand, the synthetic leather has an efficient antibacterial performance, growth and reproduction of bacteria on the surface of the synthetic leather can be effectively inhibited, a clean and sanitary environment is provided, and human health can be kept.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a coarse-wrinkled thin-skin synthetic leather. Background technique [0002] Synthetic leather refers to plastic products that simulate the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. [0003] However, most of the synthetic leather currently on the market has some problems, such as poor flexibility, poor wear resistance, unnatural wrinkle of synthetic leather, thick creases, poor resilience, and stiff hand feeling; 1. Affected by environmental conditions during use, mildew and bacterial growth often occur. In severe cases, not onl...
