A highly breathable composite automotive leather structure

Abstract

The invention discloses a highly breathable composite automobile leather structure, which includes a dermal layer and a peristaltic layer. The peristaltic layer is located below the dermal layer. The peristaltic layer is cavity-shaped and has vertically arranged elastic members inside. Both ends of the member are fixed on the inner wall of the peristaltic layer; the elastic member divides the peristaltic layer into several compartments; each elastic member is provided with a vent pipe, and one or both ends of the vent pipe are provided with air valves; one end of the peristaltic layer It is equipped with an air inlet pipe and an air outlet pipe at the other end; an electric heating layer is electrically heated with a peristaltic layer underneath; a pearl cotton layer, the pearl cotton layer is arranged below the electric heating layer; a sound insulation cotton layer, the sound insulation cotton layer is arranged below Below the pearl cotton layer; wooden layer, the wooden layer is located below the sound insulation cotton layer. The composite automobile leather of the present invention has good air permeability and is very suitable for people who use cars for a long time.

Description

technical field [0001] The invention relates to the technical field of automobile leather, in particular to a highly air-permeable composite automobile leather structure. Background technique [0002] Leather refers to the denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. It is a kind of clothing and craft materials. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. The leather industry covers the main industries such as tanning, shoemaking, leather clothing, leather goods, fur and its products, as well as supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories. The downstream has a high degree of correlation, relying on market pull, and its products are evergreen. It has the characteristics of earning foreign excha...
