Leather material based on artificial grain surface layer, artificial grain surface layer and processing method

Abstract

The invention discloses a leather material based on an artificial grain surface layer, the artificial grain surface layer and a processing method of the leather material based on the artificial grainsurface layer. The leather material comprises the artificial grain surface layer and a bottom layer, wherein the artificial grain surface layer comprises a fine collagen fiber bundle, the fine collagen fiber bundle in the artificial grain surface layer and branches of the fine collagen fiber bundle are intertwined mutually, and the fineness of a main body of the fine collagen fiber bundle in the artificial grain surface layer is smaller than that of the main body of fibers in the bottom layer. The processing method comprises the following steps: (1) manufacturing the fine collagen fiber bundle; (2) forming a web by using the manufactured fine collagen fiber bundle; (3) processing the leather material formed by the artificial grain surface layer formed by intertwining the fine collagen fiber bundle and the branches of the fine collagen fiber bundle mutually and the bottom layer combined with the artificial grain surface layer through a spunlace process. In the invention, the leather material is formed by remanufacturing the artificial grain surface layer by using the collagen fiber bundle in leather, so that the performance, structure and appearance of the artificial grain surface layer in the leather material are extremely similar to the grain surface layer of the leather, to improve comfort, affinity, breathability and hygroscopicity of the leather material.

Description

Technical field The invention relates to an artificial grain surface layer processed from slender collagen fiber bundles and a leather material made from the artificial grain surface layer. Background technique Leather is a commonly used product in people's daily life. At present, leather mainly includes real leather and imitation leather. "Real leather" refers to products made of animal real leather. With the development of industry, people have developed many forms of imitation leather. Imitation leather is generally made of cloth made of chemical fiber as the base material, and then PU, PVC or other Resin materials are coated or laminated on one side of the above substrate to make a product that looks like real leather. This type of product is also called: artificial leather, synthetic leather, etc. "Real leather" is a leather with certain acid resistance, alkali resistance, and humidity and heat resistance after a series of physical and chemical processing is carried out f...
