Abstract

The invention relates to a preparation method of completely environment-friendly leather base cloth. The preparation method includes the following steps that firstly, polyester fibers are dispersed into water, and polyester fiber turbid liquid is prepared; and a dispersing agent is added in, uniform stirring is performed, and a polyester solution is obtained; secondly, the polyester solution is used for preparing two layers of polyester paper through a paper making method by means of two upper and lower paper machines, the two layers of upper and lower polyester paper are made to be compositedwith base cloth through a composting roller, the base cloth is made to be in the middle, the polyester paper is made to be on the two sides of the base cloth, and the leather cloth is obtained; and thirdly, the leather cloth is subjected to high pressure spunlace treatment and pressing dewatering, and then enters a drying cylinder to be dried, winding and final slitting are performed, and the completely environment-friendly leather base cloth is obtained. The leather base cloth prepared through the preparation method is simple in step, forming is easy, drying is easy, productivity is high, and the leather base cloth can be used for replacing animal leather, is attractive, economical, practical and wide in purpose, and can be used for automobile trim, cloth materials and the like.

Description

technical field [0001] The invention relates to a preparation method of a completely environment-friendly leather base cloth, and belongs to the technical field of composite spunlace nonwovens. Background technique [0002] At present, most of the synthetic leathers on the market are made of organic solvent-based PU resin as the base layer and surface layer, that is, to obtain PU leather; this type of PU resin is passed through toluene, xylene, acetone, butanone, ethyl acetate, Dimethyl formamide etc. are used as solvents by solvent polymerization, and these organic solvents are all harmful substances. During the process of foaming and synthesizing PU leather, harmful gases will be produced, which will affect the health of the body, and the harmful substances will pass through the water. And air emissions, serious environmental pollution, poor environmental protection. [0003] Chinese patent document CN101871169 A discloses a method for making leather materials. The enviro...
