PROCESSING
We treat our skin in a classic way, carefully maintaining a low level of environmental impact. The quality of each product is guaranteed by our control, and we will control it very carefully.
Only leather subjected to treatments and rigid controls, which ensure its value, are used to cover and decorate bella pelle sofas and furnishing accessories.
01 The slaughterhouse in the origin of raw leather will use industrial salt to pickle and preserve the fresh cow leather obtained from slaughtering Transportation and storage. Upon arrival at the factory, they shall be stacked and stored after inspection.
02 Through the mechanical action of the rotating drum, the dirt on the fur surface is washed away to make the fur reFill with water and return to fresh skin state.
03 Use the through meat remover with blade to remove the useless floating meat and subcutaneous fat on the raw skin, which is conducive to the penetration of materials.
04 By adding alkaline materials, under the rotating action of the drum, the collagen fibers of the skin will be in an expanded state after loosening, which is convenient for the production of the next process (in the water immersed drum).
05 Use the annular belt knife of the peeling machine to divide the alkali skin into the first layer and the second layer, and carry out subsequent processing separately.
06 Add salt and acid to the drum to further remove the non fibrin in the skin and increase the gap between collagen fibers to prepare for tanning (in the tanning drum).
07 The tanning agent is added to the drum, and the tanning agent is combined with the leather fiber to give the cow leather corrosion resistance, stability, strength and elasticity. The tanned leather blank is blue, so it is called blue (wet) leather.
08 According to the thickness requirements of the finished leather, the cylindrical shaving blade of the shaving machine is used to make the thickness of the leather blank uniform.
09 Consolidate the previous (primary) tanning results, and make the leather fiber more elastic and soft by adding fatliquoring agent. The combination of dye and leather fiber makes the leather have the color required by customers.
10 The leather is laid flat on the workbench. Under the action of temperature and vacuum negative pressure, the leather fiber is compacted and shaped, and the grain surface is more flat and fine, so as to achieve the purpose of preliminary drying.
11 Through the physical knocking action of the vibration softener, the bonded leather fibers become moderately loose, which helps the leather obtain a certain softness.
12 Use sandpaper to slightly polish the leather grain surface to make the grain surface flat, fine and uniform, so as to prepare for the finishing of the later process.
13 Press different textures on the leather surface according to the style of the target product to increase the aesthetic feeling of the leather appearance;
14 The primer slurry is composed of colorant, polyurethane resin and additives to cover the leather evenly.
15 Under certain temperature and time conditions, hang the finished products and let them stand, so that the leather smell can be fully distributed.
