Problems solved by technology

[0003] With the continuous development of leather technology, its resistance has been greatly improved, but because the leather is exposed to the external environment for a long time, it is easily oxidized and cracked by the environment, and the existing leather is weak in tensile cracking ability. Leather is prone to cracks during repeated use. On the one hand, the cracks will affect the beauty of leather products. On the other hand, the cracks produced during long-term use will easily crack the leather surface.
In addition, the current anti-cracking ability of leather can not meet the requirements of some specific occasions

Abstract

The invention relates to the technical field of leather production and specifically relates to a production method of anti-cracking leather. The production method comprises the following step of sequentially performing primary coating, tumbling, floating coating, tumbling, scratching, color correction and drum falling treatment on a leather material with a plump leather body and general fur, wherein in the primary coating step, a cationic wax agent and acrylic resin are used for being dissolved in water for spray-coating treatment; in the tumbling step, a tumbling machine is used for tumbling; in the floating coating step, a leather hand feeling agent and waterborne color-changing wax are used for being dissolved in the water for spray-coating treatment; in the top coating step, a hand feeling agent is used for being dissolved in the water for spray-coating treatment. By adopting the method provided by the invention, an obtained leather finished product has the advantages of strong anti-cracking capability and no need of frequent washing, the service life of the leather is prolonged, the original luster of the leather is kept to the greatest extent, strong compressive capacity is achieved, and the leather is less prone to damages during a using process.

Description

technical field [0001] The invention relates to the technical field of leather production, in particular to a production method of anti-cracking leather. Background technique [0002] Leather is a material commonly used in daily life. It is used in various aspects such as dressing and hats, furniture making and so on. [0003] With the continuous development of leather technology, its resistance has been greatly improved, but because the leather is exposed to the external environment for a long time, it is easily oxidized and cracked by the environment, and the existing leather is weak in tensile cracking ability. Leather is prone to cracks during repeated use. On the one hand, the cracks will affect the aesthetics of leather products, and on the other hand, the cracks produced during long-term use will easily crack the leather surface. In addition, the current anti-cracking ability of leather cannot meet the requirements of some specific occasions. Contents of the invent...
