Water-based directly-coated fabric sofa leather

Abstract

The invention belongs to the technical field of leather, and particularly relates to water-based directly-coated fabric sofa leather and a water-based directly-coated fabric sofa leather production process. The water-based directly-coated fabric sofa leather is prepared by preparing a leather base fabric, a bottom gray cloth filler and a cover, conducting ironing, preparing a foaming layer, coating middle layer slurry, rolling surface slurry, conducting embossing, and preparing top layer effect slurry to obtain the finished fabric product. Polyurethane is squeezed into the fabric through rolling so that the polyurethane can be left in the fabric after the fabric is dried and the fabric can give the thick and soft real leather impression, the surface of the fabric is ironed into a mirror surface under the high temperature and low pressure of an ironing machine so that the surface of the fabric can be flat and smooth, the fabric is filled to have the leather texture through the unique and simple method, the environment-friendly water-based polyurethane resin is added, and the fabric produced after being decorated through rolling, spraying, pressing, knocking, scalding and other leather processing gives the thick and soft real leather impression like leather.

Description

technical field [0001] The invention belongs to the technical field of leather, in particular to a water-based direct-coating sofa leather. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. In the process of human evolution, people found that some plant juices or mineral oils have certain tanning properties on leather, and raw leather is more breathable and antiseptic after being soaked in juice. So that the board has physical and chemical properties such as softness, tear resistance, and bending resistance. The leather of this period really has the characteristics of leather products. And this juice we call tanning agent. The tanning industry developed to the middle o...

Problems solved by technology

(2) The challenge of artificial leather and synthetic leather to natural leather Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural characteristics. Leather has long been unable to meet people's needs

Its disadvantages: high cost, cumbersome production process, and lighter weight than genuine leather

[0015] People love natural leather because natural leather has superior hygroscopicity and dehumidification functions, but natural leather will be short-lived no matter the source of material is not enough, or the pollution of the environment in the production process. Now we use textile fabrics for The base cloth of leather, together with the technology and material of leather, overcomes the disadvantages of cloth, such as flat, thin, loose, poor hand feeling, and easy to wrinkle during use
