Abstract

The invention provides a production method of PU (polyurethane) sofa leather with high cold resistance and solves the technical problems of complicated operation process, need of manual operation, low production speed and the like of a conventional preparation method. The production method of the PU sofa leather with high cold resistance comprises steps as follows: a, base layer selection: cowhide or sheepskin commercially available in the market is selected as a base layer, and the base layer is cut into a rectangular shape through a cutting device; b, PU layer coating: one side surface of the base layer is coated with a PU layer in a spraying manner through a leather spraying device; c, compounding: a fabric layer is compounded on the other side of the PU layer through a compound device, and commercially available warp knitted fabric is adopted as the fabric layer. The production method of the PU sofa leather with the high cold resistance has the advantage of high production speed.

Description

technical field [0001] The invention belongs to the technical field of sofa leather, and relates to a production method, in particular to a production method of high cold-resistant PU sofa leather. Background technique [0002] Sofa leather is the main raw material for making leather sofas. There are many raw materials for sofa leather on the surface of sofas, including genuine leather sofa leather, PU sofa leather, PVC shoe upper leather, etc. Leather sofa leather generally has cowhide, pigskin, and horsehide. Cowhide is divided into yellow cowhide and buffalo leather, which are divided into first layer, second layer and third layer according to their layers. The sofa is made of soft leather. It is better to have a large area of ​​sofa leather, which can increase the cutting rate and reduce seams. There is a kind of leather called modified leather. Modified leather is processed and painted on the leather surface, and it can be pressed with different textures. Some painted...
