Description

The invention relates to dyeing and finishing production, and in particular to methods of dyeing textile materials primarily from wool fiber with active dyes.

Known plus-roller method of dyeing wool with fixing the dye at room temperature / Romanova MG, Gordeeva N.V. Active dyes in the textile industry. - M., 1986, p. 103 /. This method is used when dyeing a wool ribbon or fabric with active dyes: as a result of dyeing, minimal damage to the fiber is observed, the formation of wrinkles is eliminated, the fiber is not yellowed, and the consumption of steam, water, and waste water are reduced. However, this method is not without drawbacks: it requires the use of special equipment, the availability of additional production facilities, a more careful selection of dyes, ensuring the achievement of high color fastness to wet treatments.

Also known is a method of low-temperature dyeing of wool using an alkaline agent / Pat. 5-98583 JP D 06 P 3/14 Method for dyeing wool using an alkaline agent / Okuda Hidefumi (JP). Stated October 4, 1991; Publ. 10/03/2000: 3 s /. In this case, the dyeing of the fibrous material occurs at a temperature of 85 ° C, sodium hydroxide is used as an alkaline agent in an amount of 0.01% or 0.04% by weight of the material to be painted. With this method of dyeing, an increase in the intensity of dyeing of the fibrous material is observed, the staining of the fiber is significantly increased. For example, when dyeing according to traditional technology at 100 ° C, the staining depth is 85%, and when dyeing at 85 ° C using sodium hydroxide, 98%. However, when dyeing wool according to the proposed method, a decrease in the strength characteristics of the fiber is observed, since the use of an alkaline agent leads to the hydrolysis of keratin in the wool.

A known method of dyeing woolen textile materials with active bromacrylamide dyes, in particular Lanazoles (Switzerland), at a temperature of about 80 ° C / Melnikov B.N., Vinogradova G.I. The use of dyes. - M.: “Chemistry”, 1986. - 109 s /. This method of dyeing woolen textile materials, having high-quality indicators, at the same time leads to a limitation of the range of active dyes used, does not increase the intensity and strength of coloring of pure-woolen textile material and does not reduce the dyeing time.

The closest is the prototype RU 2001120438 A1, 06/20/2003, BI 0317. where an oxidation-reduction system containing hydrogen peroxide and a reducing agent is used as an intensifier of low-temperature dyeing of textile materials with active dyes. The dyeing process is carried out at a temperature of 75-80 ° C with preliminary processing of the textile material with a composition including a dye intensifier, nonionic surfactant, acetic acid and other auxiliary substances, for 10 minutes at 35-40 ° C.

The technical result of the proposed solution is to increase the manufacturability of the low-temperature dyeing process through the use of organic nitrogen-containing additives and increase the intensity of the dyeing of textile materials consisting of protein as well as cellulose fibers.

This object is achieved by the fact that before low-temperature dyeing with active dyes of textile materials, mainly from wool fibers, the textile material is pretreated with an organic nitrogen-containing additive selected from the group comprising an amino acid or nitrogen-containing enzyme, or an enzyme of the class of oxidase-peroxidase EC 1.11.1.3 in concentration 0.2-2.5% by weight of the material to be painted, and dyeing is carried out for 120-130 minutes. The proposed additives that intensify the dyeing process are non-toxic, environmentally friendly, effective in small concentrations. Thus, their use is effective from the point of view of labor protection and the economy. According to the proposed method, pretreatment of textile material is carried out before dyeing, it can be wool, silk, cotton, viscose, a solution containing auxiliary substances and an amino acid, for example

or enzymes of the hydrolysis class:

or class enzyme oxidasectases

The concentration of amino acids named I, II, III, IV, V, VI in the coloring solution is 2-2.5%, and the concentration of the used enzymes named VII, VIII, IX, X is 0.2, -0, 3% by weight of the material to be painted. The dyeing time of textile materials is 120-130 minutes.

Thus, the claimed combination of features allows you to show them both known properties and additional ones, namely, to expand the range of active dyes used, increase the intensity and strength of dyes on textile materials, as well as reduce dyeing time.

The following are examples illustrating the essence of the present invention.

In Example 1, we dyed a pure-woolen textile material with its preliminary treatment with ε-aminocaproic acid (I), which is carried out on a Hisaka laboratory apparatus with a 1:75 bath module. According to example 1, the indicators of the dyed fibrous material with active bright yellow dye 5XX with amino acid (I) are tabulated.

Samples of dyed fibrous material were tested in accordance with the requirements of GOST with the definition of the following indicators:

Color fastness to washing (GOST 9733.8-83);

The intensity of the staining was judged by the reflection coefficient, which was determined on the leukometer f. C. Zeiss (Germany).

The dye content in the residual bath was determined on a KFK-2 photoelectric colorimeter at λ _max = 440 nm by measuring the optical density of the spent dye solutions.
