The method of processing of fur skins

 

(57) Abstract:

The method refers to the fur industry and can be used in the processing of fur skins. Fur skins subject: soaking off the water composition that includes sodium chloride and comprehensive preparation on the basis of cyclic terpenes. Mezdra clean water, comprising a surfactant. Tan water composition that includes sodium chloride and organic acid. When: soaking off as an integrated drug drug use on the basis of the oxygen-containing cyclic terpenes General formula C10H16About and implement 13-15 o'clock in the aqueous composition is administered sodium chloride equally in two stages at the beginning of treatment and after 8-9 h together with an organic acid. Degreasing combined with tanning, while sodium chloride is added to an aqueous composition simultaneously with surface-active substance. As an organic acid using acetic acid or a mixture of acetic and formic. The method can reduce the mass of fur skins by 10-14%, to increase the strength of hair with Koshevoy cloth to 44-48% and reduce the duration of treatment on 19-23%. 1 C. p. F.-ly, 2 tab.

The present invention Rel is nom production at tanning of fur skins.

A method of processing of fur skins, in particular muskrat by soaking the 1st of water, comprising, g/l: sodium chloride - 20,0, surfactant - 2.0 V for 20-24 h at a temperature of 35oC, meskene, degreasing for 1.5 hours at a temperature of 38-40oC water, comprising, g/l: sodium chloride - 10,0, surfactant - 2,0, soaking 2nd in 2 to 6 hours at a temperature of 30-32oC, tanning, etc.

(Processing muskrat pelts M, Createrepo, 1993)

A method of processing of fur skins allows you to achieve the quality required by the Standards for the respective product, however, it has the following disadvantages:

- duration of treatment;

fur semi-finished product has considerable mass, which determines the mass of fur and affects its properties;

insufficient bond strength of hair with Koshevoy cloth.

The main problem to address with the inventive method, is to improve the quality, namely: reducing the weight and increase the strength of hair with Koshevoy tissue while reducing processing time.

This object is achieved preprocessing essential features, sufficient to achieve the technical result.

In the method of processing of fur skins by soaking in water composition that includes sodium chloride, meskene, degreasing and tanned, with: soaking off impose additional probiotic preparation on the basis of the oxygen-containing cyclic terpenes General formula C10H16O in the amount of 3.0 - 5.0 g/l and implement 13-15 hours, the sodium chloride is introduced into the aqueous composition in an amount of 40.0 - 50.0 g/l equally in two stages - at the beginning of treatment and after 8-9 hours together with an organic acid in the amount of 6.0-7.5 g/l, and degreasing combined with tanning.

As an organic acid using acetic acid or a mixture of acetic and formic.

Comprehensive preparation on the basis of the oxygen-containing cyclic terpenes General formula C10H16O produce industry on the basis of THE 238100-12/0-00302474-98 "Drug Gamma.

Considering the whole set of essential features, the inventive method of processing of fur skins meets the condition of novelty.

Comparative analysis of the proposed technical solutions to the prototype (see table. 1) shows that the proposed method for the processing of fur skins otlicials the differences and account for the distinctive features of the proposed method, namely: when: soaking off impose additional probiotic preparation on the basis of the oxygen-containing cyclic terpenes General formula C10H16O in the amount of 3.0 - 5.0 g/l and implement 13-15 hours, the sodium chloride is introduced into the aqueous composition in an amount of 40.0 - 50.0 g/l equally in two stages - at the beginning of treatment and after 8-9 hours together with an organic acid in the amount of 6.0-7.5 g/l, and degreasing combined with tanning. The present invention may be found to comply with the condition of inventive step, so as not detected known technical solutions that have the signs consistent with its hallmarks.

The mentioned set of features in comparison with the prototype (see table. 1, examples 1-3) achieve the claimed technical result: decrease the weight and increase the strength of hair with Koshevoy tissue while reducing processing time.

The stated parameters are optimal (see tab. 2, examples 4 and 5).

Data supporting the achievement of the claimed technical result is shown in table. 2.

On standardized indicators skins fully meet the requirements of GOST.

Ways is 13-15 hours water composition, containing (g/l) sodium chloride 40-50, surfactant nonionic - 2.0, drug Gamma-based oxygen-containing cyclic terpenes General formula C10H16O - 3,0-5,0, organic acid - 6-7,5. In the barge pour water, give half the proportion of sodium chloride, after stirring analyze its content in the solution, add the surfactant and the drug Gamma and download skins. After 8-9 hours after the start of treatment give the second half of the sodium chloride and add organic acid and continue processing within 5-6 hours. After finishing abrasives press, mestat over the entire area of the leather and produce degreasing - tanned skins for 7-9 hours at a temperature of 30-35oC composition, comprising, g/l: sodium chloride 40-50, surfactant - 2,0, namely: in the barge pour water, add sodium chloride, surfactants, mix and download skins. 1,5-2,0 from the beginning of the process are sodium thiosulfate and after another 30 min chrome tanning agent. The process and all processing will continue at the current technology.

Specific examples of the proposed method are given in table. 1 (examples 1-3).

The proposed method for processing fur is allowed:

to reduce the mass of fur skins by 10-14%;

to increase the strength of hair with Koshevoy cloth to 44-48%;

- reduced processing 49-51%.

Based on the above we can conclude:

the proposed solution is new and meets the condition of "inventive step", as known from the prior art revealed no effect of distinguishing essential features of the present invention to achieve the technical result. Using the proposed method provides this technical result, which indicates compliance of this invention the term "industrial applicability".

1. The method of processing of fur skins by soaking in water composition that includes sodium chloride, meskene, degreasing and tanning, wherein at: soaking off impose additional probiotic preparation on the basis of the oxygen-containing cyclic terpenes General formula C10H16O in the amount of 3 - 5 g/l and hold her 13 - 15 h, while sodium chloride is injected into the aqueous composition in an amount of 40 - 50 g/l equally in two stages - at the beginning of treatment and after 8 to 9 h together with an organic acid in the amount of 6 - 7,5 Eskay use acetic acid or a mixture of acetic and formic.
