Abstract

The invention provides a high-simulation-degree leather composite sofa fabric and a preparation method thereof. The sofa fabric comprises a PU leather layer, a coating resin surface layer, a fabric layer and a fabric bottom layer, wherein the upper surface of the PU leather layer is coated with the coating resin surface layer; the fabric layer and the fabric bottom layer are sequentially arrangedon the lower surface of the PU leather layer; the PU leather layer comprises base cloth, a bottom layer, a middle layer and a surface layer, and the surface of the base cloth is sequentially coated with the bottom layer, the middle layer and the surface layer from inside to outside. The sofa fabric has the air permeability and flexibility of leather, has the characteristics of air permeability, environmental friendliness, excellent hydrolysis resistance, aging resistance and the like and is a first-choice fabric of functional sofas and soft sofas.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather, and in particular relates to a highly artificial leather composite sofa fabric and a preparation method thereof. Background technique [0002] Synthetic leather is a relative term to "leather" (that is, real leather). Also known as artificial leather, synthetic leather. There is no standard statement for synthetic leather in our country. Generally, it is divided into PVC artificial leather and PU synthetic leather according to the type of surface resin. [0003] Artificial leather can be divided into many types due to the different synthetic resins used in artificial leather, different types of substrates, different production processes, whether there is foaming, and different uses. [0004] Polyurethane artificial leather is divided into dry polyurethane artificial leather and wet polyurethane artificial leather. The so-called dry-process polyurethane artificial leather refers to a ...
