Problems solved by technology

At present, with the changes in the market and the improvement of consumer tastes, the requirements for the grade of synthetic leather are getting higher and higher, but its breathability and moisture permeability have not been well resolved, especially in hot and humid conditions. The breathability and moisture permeability of the raw material have high requirements, and the moisture permeability is too poor to easily produce peculiar smell and affect the user experience. Therefore, it is urgent to develop a wet-process Yangbuck synthetic leather and its preparation method.

Abstract

The invention provides a wet-processed yambar synthetic leather and a preparation method thereof. The wet-processed yambar synthetic leather comprises: a base cloth composed of a fabric sheet; a surface layer based on a water-based polyether polyurethane coating composition, the surface layer is located on the On the base cloth, the surface layer has a porosity of 80-90%, and the water-based polyether polyurethane coating composition comprises: water-based polyether polyurethane 70-85wt%; fiber powder 5-10wt%; first foaming agent 3 -6wt%; second foaming agent 3-5wt%; dispersant 1-3wt%; wetting agent 0.5-1.0wt%; bentonite 1-2wt%; wherein, the fiber powder is composed of 95-97wt% cellulose and 3-5wt% fatty acid ester composition. The wet-process yambar synthetic leather provided according to the present invention has excellent air and moisture permeability, ideal yellowing resistance, and a fine and velvety surface.

Description

technical field [0001] The invention relates to the technical field of synthetic leather manufacturing, in particular to a wet-process yambar synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather products have the characteristics of softness and wear resistance. They are not only cheap, but also can achieve the effect of artificial leather. They have been widely used in automobiles, luggage, clothing, footwear and other products. At present, with the changes in the market and the improvement of consumer tastes, the requirements for synthetic leather grades are getting higher and higher, but its breathability and moisture permeability have not been well solved, especially in hot and humid conditions, the synthetic leather The air permeability and moisture permeability of the leather has high requirements, and the moisture permeability is too poor, and it is easy to produce odor, which affects the user experience.
