RU2492195C1 - Composition for colour finishing of fur coat - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: invention relates to the fur industry and can be used in finishing ship-fur and fur half-finished products. The composition for colour finishing of fur coat contains products of dissolving collagen, dexpanthenol, an acid dye and water, wherein components of the composition are foamed by mixing in a double-blade mixer with a revolution speed.

EFFECT: composition improves aesthetic and colour properties, increases lustre of the fur coat, reduces susceptibility to felting, thereby preserving heat-insulating properties.

Description

The invention relates to the fur industry and can be used in the decoration of sheepskin-fur coat and fur-fur semi-finished product.

Known methods of enhancing the color tone or changing the natural color of the pigmented hair by dyeing with various classes of dyes [1].

However, these methods require the implementation of additional technological processes, including sometimes - pickling with metal salts, bleaching, etc.

A known method of dyeing the hair of a fur-fur semi-finished product, which consists in applying to the hair a namaz painted with dyes of various classes of collagen dispersions [2].

The disadvantage of this method is the lack of aesthetic effect. When processing the hair coat according to the described method, a protective rather than coloristic effect is manifested to a greater extent, due to the peculiarities of the interaction of dyes with collagen dispersion and the nature of the distribution of the composition components on the hair: the dye is located directly on the hair in the form of a colored ring, and on top of the collagen sheath variance.

Known coating composition containing an aqueous dispersion of the polymer, latex, wax emulsion, penetrator, which is foamed and applied in a foam state on the substrate [3].

The disadvantage of the proposed composition is:

- the complexity of the composition,

- unsatisfactory indicators of aesthetic and operational properties of the hair,

The technical task of the invention is to optimize the composition, expand the spectrum of application of the composition, improve its technological properties by giving the substrate shine and reduce the tendency to layering of the hair.

The problem is achieved in that the color composition includes the following components, in wt.%:

Collagen Dissolution Products (PPH) 30-50 Dexpanthenol 5-15 Acid dye 0.05-0.15 Water rest

The components of the composition are foamed by mixing in a two-blade mixer with a speed of 4000-6000 per minute, for 5-15 minutes.

As PPH, an acetic acid dispersion of collagen with a dry residue of 3% is used.

Dexpanthenol

R-2,4-dihydroxy-N- (3-hydroxypropyl) -3,3-dimethylbutanamide

Table 1 shows the compositional options

The proposed composition has a homogeneous foamy state, uniformly colored. The technological effect of the use of the composition for processing the fur semi-finished product is illustrated by the indicators given in table 2.

The resulting composition is applied by spreading on the hairline of the fur.

Table 2 shows the quality indicators of the semi-finished product, after processing.

The indicators shown in the table indicate that this treatment leads to:

- to obtain a vivid coloristic effect;

- to increase the resistance of the hair to abrasion due to the leveling of microdefects;

- to reduce the volatility of the hair

The proposed composition allows to improve aesthetic and coloristic properties, increase the shine of the hair, reduce the tendency to shedding and thereby contribute to the preservation of heat-protective properties.
