- Belt embossing machine is a machine for processing leather, mainly including tanning, dyeing, classification, polishing, finishing, top coating protection, etc. After these steps, you can get a completely processed leather. The next step is to emboss the leather. Next, let’s share the process of leather processing:
- Processing flow of belt embossing machine:
- Tanning
Tanning can be completed through various tanning agents, such as chrome powder. After tanning, the leather has some blue, which is why the raw leather after tanning is called wet blue leather. The purpose of tanning is to keep the leather for a long time without deterioration. - Staining
The leather is dipped, that is, the leather surface and interior will be dyed. After the dyeing step is completed, the wet blue skin becomes skin germ. - Classification
According to different natural characteristics and intended uses, different kinds of leather are produced, mainly including Aniline aniline leather, Semi Aniline semi aniline leather, Pull Up waxed leather, Suede nubuck leather, Pigmented finish leather and Bycast two-layer laminated leather. - Grinding
Polish the top layer with sandpaper to make the surface smooth, so as to remove most of the natural marks. Full grain leather is not polished and can not have obvious defects and marks, so it is more valuable than finishing leather. - Embellishment
After finishing, the defects on leather can be covered, and the color can be consistent. With electric heating plate or roller embossing, the required texture can be pressed and the natural mark can be better hidden. Transparent top coating and solid color can prevent color loss, protect the leather, and increase the feel and luster. - Top coating protection
Top coating protects the leather from stains and corrosion, and prevents the color shifting of clothes. Use of non professional cleaners, such as alcohol and soap, will damage the top coating. After the top coat is damaged, the leather surface seems to be clean, but the surface becomes sticky, which will cause color bleeding with the clothes.
