Abstract

The invention relates to a preparation method of environment-friendly leather base cloth. The preparation method comprises the following steps: (1) dispersing polyester fibers into deionized water, and carrying out uniform stirring to obtain a polyester fiber solution; (2) preparing two polyester fiber layers from the polyester fiber solution, and compounding the two polyester fiber layers with polyester fiber base cloth in a manner that the polyester fiber base cloth is located at the middle and the polyester fiber layers are arranged on the two sides of the polyester fiber base cloth, thereby obtaining three-layer composite cloth; and (3) carrying out high-pressure swing spunlace reinforcement, squeezing dehydration and vacuum water absorption on the three-layer leather base cloth, and conducting drying to obtain the environment-friendly leather base cloth. The environment-friendly leather base cloth prepared in the invention eliminates hydro-acupuncture lines on the surface of a product and is free of fuzzing and layering, a cloth surface is smooth and tidy and feels soft and fine, and the finally prepared environment-friendly leather base cloth has density of 0.2-90 g / cm<2> andgram weight of 110-350 g / m<2>.

Description

technical field [0001] The invention relates to a method for preparing an environmentally friendly leather base cloth, belonging to the technical field of nonwovens. Background technique [0002] At present, China's production capacity of artificial leather and synthetic leather has accounted for more than 70% of the world's total output. With the continuous emergence of new technologies, the synthesis technology of artificial leather and synthetic leather is also developing continuously. Now most of artificial leather and synthetic leather are made of fiber base cloth as reinforcement material, polymer resin as matrix, and are formed by coating or impregnation. The performance of the composite material, its base fabric and its development determine the development of the artificial leather industry. [0003] However, in the production process of artificial leather and synthetic leather, there are still serious pollution problems, and the products also have harmful pollutio...
