Problems solved by technology

At present, the existing microfiber synthetic leather mainly uses non-woven fabric as the base layer and polyurethane as the surface layer. The polyurethane surface layer is painted on the non-woven fabric base layer to form a product, but the surface layer of such microfiber synthetic leather The degree of polymerization with the base layer is unreliable, and it is prone to separation, that is, the tear strength of the surface layer and the base layer is not high, the abrasion resistance is poor, and the air permeability of the surface layer is poor

Abstract

The invention discloses microfiber synthetic leather with high wear resistance and a preparation method thereof, and aims to improve the wear resistance of the whole surface layer. The high-manganesealloy is added into the components of the surface layer; however, due to the addition of the high-manganese alloy, the hand feeling of the surface layer is influenced; the cashmere fibers are added toimprove the hand feeling; however, the cashmere fibers are soft and light in weight and cashmere fibers and other components are difficult to mix. A proper amount of corncob powder is added, cashmerefibers are adsorbed by the corncob powder to form a dynamic suspension dispersion system in water and then other components of the surface layer are mixed so that the cashmere fibers are uniformly mixed with the other components; in addition, the corncob powder has wear resistance and toughness so that the corncob powder is matched with the surface layer for use.

Description

technical field [0001] The invention relates to a superfiber synthetic leather with strong abrasion resistance and a preparation method thereof. Background technique [0002] 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 demand for leather has doubled, and the limited amount of natural leather has long been unable to meet this demand. In order to solve this contradiction, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the deficiency of natural leather. At present, the existing microfiber synthetic leather mainly uses non-woven fabric as the base layer and polyurethane as the surface layer. The polyurethane surface layer is painted on the non-woven fabric base layer to form a product, but the surface layer of such microfiber synthetic leather The degree of polyme...
