Preparation process of three-dimensional embossed leather

Abstract

The invention relates to the technical field of leather, and discloses a preparation process of three-dimensional embossed leather. The preparation process comprises the following steps that finishing is carried out, specifically, recycled raw leather is separately placed according to the size, the raw leather with the same thickness and size is placed together, and preliminary classification and finishing are carried out on the raw leather; and soaking is carried out, specifically, a disinfectant is added into warm water, then the temperature of clear water is measured, the temperature of the clear water is adjusted according to different types of leather, then the raw leather is soaked in the clear water, and meanwhile, the soaking time is controlled according to different types of the raw leather. According to the preparation process of the three-dimensional embossed leather, the leather is tanned, so that the part difference is effectively reduced, loose and soft parts such as abdomen and skirting parts are well filled, the physical performance of the whole leather is more uniform, the cutting rate of the leather can be improved, the toughness of the processed leather is improved, the production quality of the leather is effectively improved, and the coated finished product is not prone to being stained, is easy to wipe off and is easy to maintain.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to a preparation process of three-dimensional embossed leather. Background technique [0002] Leather is denatured 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. Texture and gloss, feel comfortable. [0003] According to the production method of the fireproof leather proposed by the Chinese authorized invention CN 108330226 B, the beneficial effect is that the fireproof leather prepared by the production method of the present invention has high strength, strong flame retardancy, high tear strength, excellent wear resistance and bending resistance, However, the leather is not pressed during the production process, which leads to poor toughness of the leather and lo...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a preparation process for three-dimensional embossed leather, which has the advantages of strong toughness, rich surface texture and increased aesthetics, and solves the problem that the leather is not pressed during the production process, resulting in the loss of leather. The toughness is not good, and the wires will loosen. At the same time, the surface pattern is fixed, the appearance is not good, and it is difficult to meet the demand in the subsequent processing.
