      Skins are an integral part in the production process of manufacturing leather goods, so this time, as their high-quality processing technology is gaining more attention.
      Before turning to the initial phase of treatment, you will need to make weighing the total number of skins. This is done in order to continue to apply to a given quantity of the right balance of chemicals. If the solution is placed on the eye and produce weighing, the outcome of the whole process can become sad, because the skins will not meet the statutory criteria and become unsuitable for further use as a valuable material.
       Performing and already knowing the total weight category skins and carrying out the sorting, you can begin initial production stage such as "otmochno - ash processes," which include the following:
  •  "Soaking", during which the accumulated salt and contaminants are removed from the skins. It lasts 14-16 hours and after it happens once in a special room hides a solution containing dirt, naphthalene, salts, fats and other important components.
  • "Obezvoloshivanie-liming" can get rid of the epidermis, hair, and alters the fibrous structure of the dermis, and by razvolokneniya defibrilyatsii.

    The next stage is called "the preparatory processes and tanning" and characterized by the presence of increased amounts of chemicals that play a major role in keeping the quality of skins. It includes the following:

  •   Neutralization  of the  dermis and  the removal  of calcium compounds  is carried out  by a  process of  "softening-deliming."
  •  To  actively  nourish  skin with a mixture  of mineral acids  and neutra l salts, it is necessary to move the     process  of "pickling." And if the process was correct, the bending skin will appear white stripe.
  •  To make the  fur of  the skins resistance to moisture using a process of "tanning", which is divided into a     number  of ways:
  1. Chrome-tanned;
  2. Vegetable-tanned;
  3. Tanning syntans.
    The final stage is known as "Chemical finishing and dyeing processes fattening through the use of which the skins acquire a quality end result. They include the following:
  • "Retanning" helps achieve the elasticity of the skin, due to the use SINTAY, chromium compounds and  other substances.
  • "Dying" provides an opportunity to get the most suitable product colors due to the use of various dyes and  organic acids.
  • "Fattening" sufficient saturate the emulsion membrane (skin). After its application, leave the skins for 20  hours prolezhku and move on to the finishing process of "drying", which is produced at a temperature of  30 C.
