Identify unit printing full-compound leather fabric

Abstract

The invention relates to an all-composite leather fabric printed with a sign unit. It comprises an inner skin layer (1), a first air-permeable layer (2), a support layer (3), a second air-permeable layer (4) and an outer skin layer (5) in sequence. The back of the inner skin layer is provided with a lining fabric layer. The lining fabric layer is a porous fabric, which includes a substrate made of porous fabric. The porous fabric also includes a bottom layer and an information layer. The bottom layer is directly formed on the On the base material, the information layer is arranged on the bottom layer, the information layer includes a machine-recognizable pattern, and the machine-recognizable pattern is formed by a plurality of marking units, and the bottom layer is a dense In the membrane, the pore size of the bottom layer is smaller than the size of the marking unit. The invention ensures that the inner and outer surfaces of the cortex are clean. The present invention can mark the whole printing of the unit.

Description

technical field [0001] The invention relates to a fabric, in particular to a composite leather fabric, which belongs to the field of textile fabrics. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. It has a special grain layer on the surface, which has natural grain and luster, and feels comfortable. The market potential of leather and its products is huge. The total global demand for leather is about 100 million square meters, which is equivalent to the output of 300 million pieces of cowhide (standard leather). China’s leather output is equivalent to nearly 70 million pieces of standard leather, accounting for about 23.33% of global leather production. [0003] Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural characteristics. However, with the growth of the world population, the human ...

Problems solved by technology

[0003] Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural characteristics. However, with the growth of the world population, human demand for leather has doubled, and the limited amount of natural leather has long been unable to meet this demand.

Therefore, artificial leather, synthetic leather, regenerated leather and other products have appeared on the market, but these imitation leather products are difficult to meet people's requirements in terms of hand feel, air permeability and durability, and the quality of such products is uneven
