Composite leather fabric for enlarging silver nanometer healthy fiber application range

Abstract

The invention relates to a composite leather fabric for enlarging the silver nanometer healthy fiber application range. The fabric comprises an inner leather layer (1), a first breathable layer (2), a supporting layer (3), a second breathable layer (4) and an outer leather layer (5) in sequence. A liner fabric layer is arranged on the back face of the inner leather layer. The liner fabric layer is a warp knitting fabric which is composed of yarn and filaments wrapping the yarn spirally. The yarn includes core yarn. The core yarn is composite filaments of silver nanometer healthy fiber or silver nanometer healthy fiber and other fiber, wherein the other fiber includes cotton, fiber, wool, Dacron, chinlon or spandex filaments as Dacron or chinlon. The composite leather ensures that the inner and outer surfaces of leather are clean, and the silver nanometer healthy fiber application range can be enlarged.

Description

Technical field [0001] The invention relates to a fabric, in particular to a composite leather fabric, belonging to the field of textile fabrics. Background technique [0002] Leather is an animal skin that has been denatured and not perishable through physical and chemical processing such as dehairing and tanning. It has a special grain layer on its surface, which has natural grain and luster, and feels comfortable. The market potential of leather and its products is great. The total global demand for leather is about 100 million square meters, which is equivalent to the output of 300 million cowhide (standard skins). China’s leather output is equivalent to nearly 70 million standard skins, accounting for approximately 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's population, human demand for leather ha...

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
