Problems solved by technology

Leather on the market is generally used for belts, leather sofas and car leather seat cushions, but its performance is often difficult to achieve the desired effect
[0004] The Chinese invention patent application with the application number 201510782629.0 discloses a process for leather highlighting and highlighting. Put the leather into the drum, add leather brightener at 30-40°C, rotate at 20-50 rpm for 20-40min, take it out and add 3000-4000U / g cellulase enzyme at 30-35°C Decompose for 20-40 minutes, dry at room temperature, and apply leather oil; this technology mainly makes the leather achieve high-gloss and high-gloss effects by adding leather brighteners. The high-gloss high-gloss leather obtained by this method is After using for a period of time, the effect of highlighting is unstable, the service life is not long, and it cannot satisfy the leather products for a long time, and the leather feels poor

Description

technical field [0001] The invention belongs to the technical field of leather, and in particular relates to a high-gloss wax leather and a preparation process thereof. Background technique [0002] Leather refers to the denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. It is a kind of clothing and craft materials. 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. [0003] In some special places, it is often necessary to use specially treated materials or materials with special properties. For example, car leather seat cushions and leather binding materials need to use high-strength leather, while ordinary leather does not have high strength. It is even more impossible to achieve the performance of strong explosive force. Leather on the market is generally use...
