The image refers to light industrialization, in particular to the technology of the manufacture of fur, and could be used during the soaking process.

Known compositions for soaking fur containing water, sodium chloride, sodium silicofluoride and sharpener1 (neutral or acid salt) t 3

The closest to the proposed technical essence and achievable effect is the composition for soaking skins of fur 2, containing a sharpener (sodium silicofluoride and enzyme preparation), salt and water at a ratio of components, g / l:

Sodium fluoride1,0

Enzyme preparation3.0

Cooking Sol2O, O

Water up to 1 l

Fur skins are treated with a known composition as follows.

Water is poured into 6apicac, guvarniu salt, sodium silicofluoride and enzyme preparation are added. After moving the solution, pelts are loaded. The process is carried out at W, C, 12, and CZ-35 C for 24 hours. Next, the skins are squeezed, the subdivision is and directed to the pickling process.

The disadvantage of the known composition is a considerable duration of treatment.

The purpose of the invention is to intensify the soaking of furs.

The goal is achieved by the fact that the composition, including water and table salt, contains tetraaminozinc as a sharpener. ethylenediamine. tetraacetate amino ammonium chloride, in the following ratio of components, in g / l:

Tetraaminozinc ethylenediamine traate totoami on tozinc ammonium chloride 150-17O

Cooking salt 20-40

Water up to 1 liter

The processing of fur skins by the proposed composition is carried out by following the procedure,

Water is poured into the bark, the p. Boiled salt and tetraaminozinc etylenediamine tetraacetateatoaminate zinc ammonium chloride are added. After mixing the solution I load the skins. The process is carried out at J. 12 and ZO-35 ° C for 2-4 hours. Then, the skins are squeezed, ground and sent to the pickling process.

In tab. 2 shows the comparative data on the processing of mink skins with the proposed composition and the prototype.

The use of the proposed composition allows to significantly intensify the process of soaking, reducing it by 6-12 times in comparison with the process carried out by a known composition,
