Embodiment 1

[0034] A kind of preparation method of environmental protection leather base cloth, comprises the steps as follows:

[0035] (1) Disperse ultra-fine and ultra-short polyester fibers with a fineness of 0.2 dtex and a fiber length of 5 mm into deionized water, and stir evenly to obtain a polyester fiber solution;

[0036] (2) Prepare polyester fiber woven base fabric on the unwinding stand, gram weight 50g / m 2 , thickness 0.3mm, spare;

[0037] The polyester fiber solution and the polyester fiber base fabric are passed through a three-layer composite former at the same time, wherein the polyester fiber solution prepares the upper and lower polyester fiber layers, and then the upper and lower polyester fiber layers and polyester fiber layers are made by 20kg pre-spunlace. The fiber base fabric is compounded, so that the polyester fiber base fabric is in the middle, and the polyester fiber base fabric is covered with polyester fiber layers on both sides, so as to obtain a three-l...

Abstract

The invention relates to a preparation method of an environmentally friendly leather base cloth, which comprises the following steps: (1) dispersing polyester fibers into deionized water and stirring evenly to obtain a polyester fiber solution; (2) preparing the polyester fiber solution into Two layers of polyester fiber layers are then compounded with the polyester fiber base cloth so that the polyester fiber base cloth is in the middle, and both sides of the polyester fiber base cloth are polyester fiber layers to obtain a three-layer composite cloth; (3) the three-layer leather The base fabric is reinforced by high-pressure swinging spunlace, dehydrated by pressing, vacuum-absorbed, and then dried to obtain an environmentally friendly leather base fabric. The environmentally friendly leather base cloth prepared by the present invention eliminates water needle marks on the surface of the product, is lint-free, and does not have layers. At the same time, the cloth surface is smooth and tidy, and the hand feels soft and delicate. The final prepared environmentally friendly leather base cloth has a density of 0.2 to 90 g / cm 2 , the weight is 110~350g / m 2 between.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly leather base cloth, and belongs to the technical field of non-woven fabrics. 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 synthetic technology of artificial leather and synthetic leather has also continued to develop. At present, most of artificial leather and synthetic leather are made of fiber-based cloth as the reinforcement material and polymer resin as the matrix, which is formed by coating or dipping. The performance of the 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 pollution t...
