Cowhide material under process treatment

The quality of material determines the long service life of men’s leather bags, and if the material of cloth is better, the leather bags will be better in waterproof, wear-resistant and tear resistance. In today’s market, canvas, nylon, cowhide and other materials are more commonly used, and the quality of these materials is very good and durable.
Raw cowhide needs to go through three stages and dozens of processes in the preparation stage. When it becomes the leather we see, it includes the preparation stage, tanning stage and finishing stage. In our preparation stage, we mainly carry out a preliminary processing. Its main purpose is to remove some useless things on animal skin, such as fat, hair, soluble protein, etc. when processing animal skin collagen fibers, it is mainly conducive to improving the quality of leather in the later processing. In the main process, it includes the steps of soaking, cleaning, depilation, liming, softening and so on.
In our tanning stage, we are mainly in a key stage of leather deformation. Using our chemical methods, we can make a great change in the structure of animal skin on collagen fibers, and turn the skin into leather. At the same time, it also determines the performance and quality of our leather. In terms of tanning, it includes chrome tanning, vegetable tanning and so on. In terms of vegetable tanning, the natural vegetable tanning agent used for tannin tanning will be relatively natural and environment-friendly without too many harmful substances. The cortex is also relatively flexible and the color is relatively single. When our heavy metal chromate is used as our chromate in chrome tanning, the main processes are divided into primary tanning, retanning, grading and so on.
At the stage of finishing and tanning, it needs our continuous finishing before it can be used as our finished leather. Finishing can make the leather surface form the appearance of many colors, luster and styles, so that the leather can always obtain a certain degree of maintenance and waterproof. In terms of process, it mainly includes slicing, neutralization, chipping, fatliquoring, softening, drying, buffing, flattening, embossing, etc.
