The method of processing of fur raw materials

 

The method relates to the processing of fur raw material for making clothes and other products. Raw material is subjected to: soaking off, mendrinou, processing the mixture of enzyme preparations containing protease and amylase in an amount of 0.1-0.5 g/L. Then carry out tanning and greasing. The technical result is to increase consumer properties of fur. table 1.

The invention relates to the fur industry and can be used in the processing of fur raw material for making clothes and other items.

A method of processing fur raw materials before tanning, comprising: soaking off, degreasing, washing, processing carbohydrase enzymes of mold Aspergillus Awamori in the amount of 1-2 g/l for 20-24 hours at a temperature of 30oC, W.to. 10, pH 4-5, tanning and greasing (SU, 204486 A, class 14 With 1/08, 26.12.67).

The disadvantage of this method is that the use of one carbohydrase enzyme can not be deleted from the leather fur all globular proteins and polysaccharides, which hinders subsequent processes.

The closest analogue of the proposed technical solution is the method of processing michaelmania drugs multimemory GH, aminocoumarin G3X at a ratio of 1:2 in the amount of 0.3-0.8 g/l, meskene, pickling, tanning, processing solution containing a mixture of enzyme preparations multivaria GH and aminocoumarin G3X at a ratio of 1:2 in the amount of 0.3-0.8 g/l at pH 4.5 to 5 and a temperature of 37-39oWith and greasing (SU, 1234430 A1, class 14 With 1/00, 9/02, 30.05.86).

The disadvantage of this method is that the mixture of enzyme preparations multimemory GH, aminocoumarin G3X is not possible to remove from leather fur all globular proteins, which hinders technological processes. Besides, the fur have enough high consumer properties.

The technical result of the invention is to improve consumer properties of fur.

This result is achieved in that in the method of processing of fur raw materials, including: soaking off, meskene, processing the mixture of enzyme preparations, tanning and greasing, processing the mixture of enzyme preparations produced before pickling and as a mixture using the following composition, wt.%: protease 60-80 and amylase 20-40 in an amount of 0.1-0.5 g/L.

A distinctive feature of the proposed method is that the processing of fur raw material before pickling mixture of enzymes, soy and polysaccharides, what facilitates processes and allows to improve operational properties of fur.

Change% ratio of mixture components and the reduction of its consumption is less than 0.1 g/l leads to an incomplete removal of globular proteins and polysaccharides from leather to fur, which degrades its quality. The increased flow of the mixture over 0.5 g/l is impractical because it does not further improve consumer properties of fur.

Technology of preparation of the composition is the following: in a container equipped with a mixer, put these enzyme preparations in the ratio, by weight. %: protease 60-80, amylase 20-40 and with constant stirring for 20-30 minutes to prepare from them a rough mix, then put it in a ball mill and get a thin mixture.

The mixture of enzyme preparations characterized by the following indicators: 1. Physical condition - fine powder 2. Color - white 3. Solubility in water - 100 g/l 4. The Proteolytic activity of 70 u/g Amylase - 30 u/g 5. Optimum action pH of 5.5-8 Method is as follows.

A party of fur raw material after soaking, meskene and cleaning-degreasing process a mixture of enzymatic drugs is 15 for 2.0 to 2.5 hours. Then the raw material is subjected to pickling, tanning, greasing and finish by standard processing techniques this kind of fur raw materials.

Example 1. Raw sheepskin fur are: soaking off and cleaning-degreasing, and then treated with a mixture of enzyme preparations of the following composition, wt. %: It HH - 60, Wiscosin - 40 in an amount of 0.1 g/l at a temperature of 30oWith and W.to. 10 within 2 hours.

This is followed by pickling, tanning, greasing and finish processing Technology, fur sheepskin, Createrepo, M., 1982.

Example 2. Raw sheepskin fur is treated as in example 1, but the processing of the mixture of enzyme preparations of the following composition, wt.%: The it GH-70, Bacterial amylase HC 86-30 carried out at a flow rate of 0.25 g/L. Pickling, tanning, greasing and finishing is carried out on the processing Technology of fur sheepskin, Createrepo, M., 1988.

Example 3. Raw materials of mink treated as in example 1, but the processing of the mixture of enzyme preparations of the following composition, wt.%: Skinazi - 80, Isoamylase - 20 is carried out at a flow rate of 0.5 g/L. Pickling, tanning, greasing and finishing is carried out on a single processing technologies mink, Createrepo, M., 1987.

Example 4. Raw sheepskin fur is treated as in example 2, but about 0.08 g/L.

Example 5. Raw sheepskin fur is treated as in example 1, but the processing of the mixture of enzyme preparations of the following composition, wt.%: Protegrin - 85, Isoamylase - 15 is carried out at a flow rate of 0.7 g/L.

Quality indicators received furs in comparison with fur on the prototype shown in the table.

Using the proposed method can improve the consumer properties of fur semi-finished product for the manufacture of clothing.
