The method of processing fur sheepskin

 

(57) Abstract:

The method relates to light industry and fur sub-sectors and can be used in Cyrano-dye production in the finish by haulage fur before finishing hair. The method includes the hauling fur sheepskin on the sawdust with the addition of turpentine and beautification of hair. When hauling impose additional complex drugs "FCF-FZ" on the basis of sodium formiate and "Gamma" on the basis of the oxygen-containing cyclic terpenes General formula C10H16About in amounts of 0.01-0.02 l one sheepskin, with their added by 1.0-1.2 hours after the start of the haul. The method improves the quality of the leather processed sheepskin fur at the expense of increased tensile strength and reduced delamination leather. table 2.

The present invention relates to light industry and fur sub-sectors, and can be used in Cyrano-dye production in the finish by haulage fur before finishing hairline.

The hauling is one of the mechanical finishing operations. For haulage use rotating sliding drums, kotorye, compression and stretching. As a consequence, the leather and fur skins, oblasts and warming up, becomes soft and plastic, which further simplifies and makes more efficient breakdown and stretching sheepskin on the machines. Hair under the influence of grinding and polishing steps sawdust is clean, crisp, and so on

There are various ways of handling fur skins by their haulage on sawdust. To enhance the mechanical impact on the leather in the drum sometimes add pieces of rubber tires or wooden balls. For intensive cleaning of hair in sawdust enter turpentine, acetic acid or glycerin. For increased Shine use a wax-like substance, when finishing odorants

(G. F. Esin, L. B. Sankin "fur Trim", M, Legprombytizdat 1994, S. 172-175).

Closest to the proposed method to the technical essence and the achieved technical effect is a method of processing fur, including hauling and beautification of hair. The hauling spend on sawdust moistened with turpentine based 0,06 l one sheepskin for 2.5 - 3 hours

(Processing of fur sheepskins, My sheepskin, allow us to achieve the quality required by the Standards for the respective product, however, in obtaining a fur processed sheepskin often see such defect, as the lack of strength of the surface layer and the delamination of the leather, which reduces the quality of the fur semi-finished product due to the emergence of cod face and Lamin.

The main problem to address with the inventive method, is to improve the quality leather fur refined sheepskin due to the increase tensile strength and reduce the delamination leather.

This object is achieved by the proposed method of processing of fur skins. The essence of the proposed method consists in the aggregate of the following essential characteristics sufficient to achieve the technical result, namely:

in the processing method fur sheepskin, including hauling sawdust on with the addition of turpentine and beautification of hair, when hauling impose additional complex drugs "FCF-FZ" on the basis of sodium formiate and "Gamma" on the basis of the oxygen-containing cyclic terpenes General formula C10H16O in amounts of 0.01 - 0.02 l one sheepskin, with their up to the TEW-based specifications accordingly, THE 301-03-115-93 "Preservative - disinfectant. PCF-PF" and 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 processing fur sheepskin differs from the known substance, techniques, and processing options. These differences constitute the distinctive features of the proposed method, namely: when hauling impose additional complex drugs "FCF-FZ" on the basis of sodium formiate and "Gamma" on the basis of the oxygen-containing cyclic terpenes General formula C10H16O in amounts of 0.01 - 0.02 l one sheepskin, with their added by 1.0 to 1.2 hours after the start of the haul.

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 distinguishing characteristics. The mentioned set of features in comparison with the prototype (see table. 1, examples 1-3) achieve the claimed technical result: appreciation is published by third parties of tensile stress.

The stated parameters are optimal (see tab. 1, 2).

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

On standardized indicators sheepskin fully complies with the requirements of GOST.

The method is as follows:

Fur sheepskin is treated on "Technologies of processing of fur sheepskin, 1988" before surgery "haul", which is done as follows: in the combined drum load of sheepskin and give the sawdust 12% humidity (based on one sheepskin) - 0.65 kg, and turpentine - 0,06 l include the rotation of the drum and rotate within 1-1,2 hours. Then, in the drum type complex drugs "FCF-FZ" on the basis of sodium formiate and "Gamma" on the basis of the oxygen-containing cyclic terpenes General formula C10H16O in an amount of 0,01-0,02 L. Then hold breakdown - Taiko, combing, grooming and beautification on current technology. Specific examples of the proposed method are given in table. 1 (examples 1-3).

The proposed method for processing fur was tested in conditions of fur production. The test results are positive.

The method allows to increase to whom and when cracking an average of 20% and the tensile strength tensile leather by 6.6% and the credit release 3.8%.

Based on the above we can conclude: the proposed technical 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".

The method of processing fur sheepskin, including hauling sawdust on with the addition of turpentine and beautification of hair, characterized in that when hauling impose additional complex drugs "FCF-FZ" on the basis of sodium formiate and "Gamma" on the basis of the oxygen-containing cyclic terpenes General formula C10H16O in amounts of 0.01 - 0.02 l one sheepskin, with their added by 1.0 - 1.2 hours after the start of the haul.

SUBSTANCE: invention concerns the fur industry and can be used in furriery-tailoring manufacture at manufacturing and repair of fur products. The method of strengthening of fur fabric leathers of a half-finished product is carried out by application and drying of a collagen-containing composition containing moist collagenic aggregation, a softener and a hardening agent. Thus the collagen-containing composition additionally contains cod-liver oil and castor oil. The composition is applied in two stages. The first stage of treatment is performed with a compound, in recalculation on a solid: collagenic aggregation 2%, glycerin 2.6-4%, oak extract 0.1%, cod-liver oil 0.2%, castor oil 0.2%, water - the rest. The second stage of treatment is performed with a compound, in recalculation on a solid: collagenic weight 6%, glycerin 7.8-12%, oak extract 0.3%, cod-liver oil 0.6%, castor oil of 0.6%, water - the rest. Drying of a fur half-finished product is performed after the first and the second application. The way allows to raise adhesion strength of body hair coat with a leather fabric, to increase useful area of a fur half-finished product due restoration of defective sites of leather fabrics and simultaneously to receive a detail with the zones differing by properties.

EFFECT: increase of adhesion strength of body hair coat with leather fabric, increase in useful area of a fur half-finished product.
