Abstract

The invention belongs to the field of leather production, and discloses leather for cow leather clothes and a production method of the leather for the cow leather clothes. The method comprises the following step of: by adjusting the working procedures of retanning, neutralizing, packed dyeing, oiling and coating, adding a dry shaving working procedure between a milling working procedure and a dedusting working procedure in a dry finishing working procedure, so that the leather for the cow leather clothes can be dryly shaved to have the thickness of 0.2-0.25mm. After the leather for the cow leather clothes is used, not only can the performances such as the softness, the fullness, the smoothness, the brightness, the extensibility, the hand feel and the disability coverage be greatly improved, but also the leather is thinner and lighter, thereby being wide in practical applicability.

Description

technical field [0001] The invention relates to a production method of garment leather, in particular to a production method of cowhide garment leather. Background technique [0002] With the continuous progress and development of society, people's living standards continue to improve, material and cultural enrichment, the demand for leather and its products in domestic and foreign markets is also increasing, and the quality is getting higher and higher. It is beautiful, fashionable, and practical. The current production of garment leather is heavy, poor in smoothness and brightness, high in extensibility, and easy to deform. Obviously, traditional products cannot fully meet the current social needs. Therefore require thinner, lighter, softer, more comfortable and good wide practical leather to adapt to market needs. Contents of the invention [0003] The invention provides a method for producing cowhide garment leather. Compared with the prior art, the produced garment l...
