Problems solved by technology

[0003] Oily wax leather, that is, leather with a waxy surface, is also one of the high-end leather materials. Most of them are made of top layer cowhide. It has good softness and water resistance, but the price is also expensive.
[0004] At present, it is rare in China to see the first layer of cowhide with both waxy feeling and cracks, and the waxy and cracked leather overcomes the lack of cracked leather's poor water resistance, and endows the waxy leather with a strong cracked texture. Research hotspots in the field

Embodiment 1

[0033] The manufacturing method of the two-layer two-color waxy crackle skin comprises the following steps:

[0034] Step 1, drying: take the two-layer cowhide material that has been processed and dyed, and dry it at 40°C for 26 hours to obtain the dried leather material;

[0035] Step 2, leather grinding: After grinding the bottom and surface of the dried leather material obtained in Step 1 in sequence, sweeping dust is carried out to obtain the leather material for grinding. Grinding the bottom and grinding the surface, the bottom grinding is: use 180 # 、220 # Grind the bottom with sandpaper, and remove the long and thick fibers on the bottom surface; the grinding surface is: use 180 # 、280 # Sandpaper grinding, in which, the belly of the leather is finely ground until the fibers on the surface of the leather are uniform;

[0036] Step 3, softening: use an octagonal drum to soften the buffed leather obtained in Step 2 at 45°C for 3 hours to obtain softened leather;

Embodiment 2

[0044] The manufacturing method of the two-layer two-color waxy crackle skin comprises the following steps:

[0045] Step 1, drying: take the two-layer cowhide material that has been processed and dyed, and dry it for 30 hours at 30°C to obtain the dried leather material;

[0046] Step 2, leather grinding: After grinding the bottom and surface of the dried leather material obtained in Step 1 in sequence, sweeping dust is carried out to obtain the leather material for grinding. Grinding the bottom and grinding the surface, the bottom grinding is: use 180 # 、220 # Grind the bottom with sandpaper, and remove the long and thick fibers on the bottom surface; the grinding surface is: use 180 # 、280# Sandpaper grinding, in which, the belly of the leather is finely ground until the fibers on the surface of the leather are uniform;

[0047] Step 3, softening: Use an octagonal drum to soften the buffed leather obtained in Step 2 at 40°C for 3.5 hours to obtain softened leather;

Embodiment 3

[0055] The manufacturing method of the two-layer two-color waxy crackle skin comprises the following steps:

[0056] Step 1, drying: take the two-layer cowhide material that has been processed and dyed, and dry it at 50°C for 24 hours to obtain the dried leather material;

[0057] Step 2, leather grinding: After grinding the bottom and surface of the dried leather material obtained in Step 1 in sequence, sweeping dust is carried out to obtain the leather material for grinding. Grinding the bottom and grinding the surface, the bottom grinding is: use 180 # 、220 # Grind the bottom with sandpaper, and remove the long and thick fibers on the bottom surface; the grinding surface is: use 180 # 、280 # Sandpaper grinding, in which, the belly of the leather is finely ground until the fibers on the surface of the leather are uniform;

[0058] Step 3, softening: Use an octagonal drum to soften the buffed leather obtained in Step 2 at 50°C for 2.5 hours to obtain softened leather;

Abstract

The invention relates to a manufacturing method of bicolor wax-texture crack split leather and belongs to the technical field of leather. The manufacturing method of the bicolor wax-texture crack split leather comprises the following steps that processed and dyed split leather is obtained, dried, ground, milled, sprayed for the first time, roll-finished, sprayed for the second time, vibration-softened, rolled with oil wax and milled in sequence, and thus the bicolor wax-texture crack split leather is obtained. According to the manufacturing method of the bicolor wax-texture crack split leather, the processed and dyed split leather is dried, ground, milled, sprayed for the first time, roll-finished, sprayed for the second time, vibration-softened, rolled with the oil wax and milled, and the technological conditions of the steps and the chemical therapy ratio are strictly controlled and optimized, so that the low-level split leather is manufactured into the high-level crack leather with the wax texture, and the crack leather further has the strong bicolor contrast effect.

Description

technical field [0001] The invention belongs to the technical field of leather, and in particular relates to a method for making two-layer, two-color, waxy cracked leather. Background technique [0002] Cracked leather, that is, leather with cracks on the surface, has a strong sense of cracks in its appearance. At present, most of the existing cracked leathers are made of top-layer cowhide, which are mostly used as high-grade leathers. In recent years, people's demand for leather products is increasing day by day, especially the demand for high-grade leather. However, the price of high-grade top layer leather is still relatively expensive. Therefore, most domestic manufacturers are seeking to develop new products. To provide people with a cow split leather product with a lower price and performance comparable to that of the top layer cowhide. [0003] Oily wax leather, that is, leather with a waxy surface, is also one of the high-end leather materials. Most of them are mad...
