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 present invention provides wet-process Yangbuck synthetic leather and a preparation method thereof. The wet-process Yangbuck synthetic leather comprises base cloth composed of fabric pieces and anaqueous polyether polyurethane coating composition based surface layer positioned on the base cloth. The surface layer has the porosity of 80-90%. The aqueous polyether polyurethane coating composition comprises 70-85wt% of aqueous polyether polyurethane, 5-10wt% of fiber powder, 3-6wt% of a first foaming agent, 3-5wt% of a second foaming agent, 1-3wt% of a dispersing agent, 0.5-1.0wt% of a wetting agent and 1-2wt% of bentonite, wherein the fiber powder consists of 95-97wt% of cellulose and 3-5wt% of fatty acid ester. The wet-process Yangbuck synthetic leather provided by the invention has excellent air permeability and moisture permeability, ideal yellowing resistance and delicate velvet surface.

Description

technical field [0001] The invention relates to the technical field of synthetic leather manufacture, in particular to a wet-process yangbuck synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather products have the characteristics of softness and wear resistance, are not only cheap, but also can achieve the effect of imitation leather, and 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 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 breathable and moisture-permeable performance of the leather has high requirements, and the moisture-permeability is too poor to easily produce peculiar smell, affect user experience, therefore, urgently need to research a kind o...
