Problems solved by technology

[0002] At present, the consumer market has higher and higher requirements for the waterproof performance of suede in the leather industry. Most enterprises can also produce leather fabrics with waterproof performance, but these leather fabrics are waterproof and lack breathability. , may cause problems such as stuffy feet and smelly feet, which greatly limits the application range of leather fabrics
[0003] In order to make the fabric both waterproof and breathable, some companies obtain waterproof and breathable fabrics by compounding leather with other materials, but this kind of fabric is easy to distort the leather, the fabric is of low grade and the process is complicated and the cost is high
Chinese invention patent application ZL200910043014.0 discloses a production method of giant salamander leather and its products, which are special in that the process parameters adopted for the characteristics of giant salamander leather are not practical for conventional leather such as cowhide

Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific embodiments.

[0018] The manufacturing method of the waterproof and breathable leather provided in this embodiment includes the following steps:

[0019] S1: Prepare raw materials, choose the predetermined wet blue hide as the embryo, and the specific wet blue hide can be selected according to actual needs.

[0020] S2: Acid rewetting, put the skin embryos into the drum machine, the weight of the skin embryos put in the drum machine can be determined according to actual needs, then fill the drum machine with water, use oxalic acid, salt and enemy water single A pair It is best to carry out acid rewetting twice for the skin embryo. After each acid rewetting, the liquid in the drum machine must be drained, and between the two acid rewettings, wash with warm water at 45°C. It should be noted that the amount of oxalic acid, salt and disulfide single A needs to be determined according to the...

Abstract

The invention provides a manufacturing method of waterproof and breathable leather. The method comprises the following steps: predetermined cow wet blue leather is selected as crust, and the crust is then sequentially subjected to the procedures of acid rewetting, retanning, neutralization, filling, dyeing and fat liquoring; a waterproof agent adopted in the fat liquoring procedure is a polymer dispersant containing silicon resin. The method provided by the invention has the advantages that the polymer dispersant containing the silicon resin is used as the waterproof agent and replaces a fluoride waterproof agent adopted in the traditional method, so that hydrophobic layers with the waterproof and breathable effects can be formed on the leather surface and in the leather, and the obtained leather further achieves waterproof performance and breathable performance as well as lower cost.

Description

technical field [0001] The invention relates to a method for making leather, in particular to a method for making waterproof and breathable leather. Background technique [0002] At present, the consumer market has higher and higher requirements for the waterproof performance of suede in the leather industry. Most enterprises can also produce leather fabrics with waterproof performance, but these leather fabrics lack breathability while being waterproof. , may cause problems such as stuffy feet and smelly feet, which greatly limits the application range of leather fabrics. [0003] In order to make the fabric both waterproof and breathable, some companies obtain waterproof and breathable fabrics by compounding leather with other materials, but this kind of fabric is easy to distort the leather, the fabric is of low grade and the process is complicated and the cost is high. Chinese invention patent application ZL200910043014.0 discloses a production method of giant salamande...
