Description

The invention relates to chemical technology of textile materials, and in particular to compositions for coloring textile materials.

The level of technology.

It is known that the printing of textile materials with pigments is carried out by applying printing ink and fixing it at a temperature of 170-180 ° C for 3 minutes. The composition of the printing ink includes a pigment, a thickener, preparations that help fix the pigment on a textile material, namely, mesh and film-forming polymers, as well as various additives, such as softeners, fixatives, catalysts, etc.

As grid-forming polymers, methylol derivatives of urea and triazine are used. In the presence of a catalyst, they form covalent bonds not only between cellulose macromolecules, but also with a pigment and a film-forming polymer.

Derivatives of acrylic acid, such as latexes and emulsions of polymers, are used as film-forming polymers. Film-forming polymers are introduced in order to impart improved properties to textile materials, for example, fullness, quality factor, softness, and others. In some cases, film-forming polymers increase the strength of the color to various physicochemical and mechanical types of processing.

Since the viscosity of aqueous solutions of net- and film-forming polymers is insufficient to obtain printing inks with the necessary technological properties, a thickener is introduced into the printing ink. However, the thickener at the places of printing ink gives the fabric a hard neck by fixing it on a textile material using a binder. When printing with pigments, an oil-in-water emulsion thickener is most often used, which is obtained by mechanical stirring of white spirit in an aqueous solution of an emulsifier (B.N. Melnikov, T.D. Zakharova, M.N. Kirillova. "Physicochemical fundamentals processes of finishing production ". M:" Light and food industry ", 1982, 280 s; B.N. Melnikov, I. B. Blinicheva, G. I. Vinogradova and others." Progress in the technique and technology of printing fabrics " M.: “Light Industry”, 1980, 264 s).

A known composition for printing textile materials with pigments, containing, g / kg:

Pigment 50-60 Latex SKS-65GP 130 Metazine one hundred Ammonium chloride four White spirit emulsion thickener Up to 1 kg

Latex SKS-65GP is a film-forming polymer, which gives the textile material softness and brightness due to the elasticity and transparency of the polymer film formed on the fabric.

Metazine is used as a crosslinking preparation for fixing pigment particles on textile material due to the formation of a spatial polymer network and covalent bonds between the preparation and cellulose.

Ammonium chloride catalyzes the formation of a spatial network (B.N. Melnikov, T.D. Zakharova, M.N. Kirillova. "Physico-chemical principles of the processes of finishing production." M: "Light and food industry", 1982, 280 s; BN Melnikov, I.B.Blinicheva, G.I. Vinogradova and others. “Progress in the technique and technology of printing fabrics.” M.: “Light Industry”, 1980, 264 s).

However, the composition is fire hazardous, with unfavorable sanitary and hygienic working conditions.

Also known composition for printing, containing, g / kg:

Pigment 80 Emucril M 200 Emucril P twenty Glikazin twenty Softener 12 Ethylene glycol fifteen Stearox 6 (1: 3 with water) twenty Ammonium sulfate (1: 3 with water) 10 Acrylic based thickener Up to 1 kg

In this composition, Emucril M and Emucril P play the role of net- and film-forming polymers; ammonium sulfate - a catalyst; glycazine, ethylene glycol, stearox 6, a softener play the role of additives that contribute to the formation of a more transparent, soft polymer film on the textile material and its stronger fixation on the textile material (B.N. Melnikov, I. B. Blinicheva, G.I. Vinogradova and others. "Progress of machinery and technology for printing fabrics." M.: "Light industry", 1980, 264 s).

However, the composition is difficult to prepare due to the multicomponent nature, does not provide sufficient strength for dry and wet friction of printed fabrics and clogs mesh patterns or adheres to shafts in the drying part of the machine, which leads to the shutdown of technological equipment.

Closest to the invention in terms of essential features is a composition for printing textile materials [Collection of reports // Herr Perkuhn "Pigment Printing", April 1996]: containing, g / kg:

Pigment twenty Luprintol RE 5 Lutexal HEF 25 Gelizarin Binder UDR 120 Water Up to 1000

Gelisarin binder is a liquid flowing aqueous dispersion of film-forming, self-crosslinking acrylate-based copolymers that have very good storage stability.

Lutexal HEF is a synthetic thickener based on (meth) acrylic acid esters.

Luprintol RE acts as an emulsifier, which contributes to a stable and fine distribution of solids (binders, pigments, softeners) in printing ink.

However, the composition has the following disadvantages:

- low color stability of textile materials printed by this composition to all types of physico-chemical and physico-mechanical treatments;

- low softness of prints on textile materials;

- the composition when printing on knitwear gives a marriage: unevenness of the print (“cloudiness”, “troubled print”);

- clogging of mesh patterns and sticking onto the shafts of technological equipment are possible.

SUMMARY OF THE INVENTION

The objective of the invention is to find a composition for printing pigments of textile materials, including pigment, thickener, binder and water, which would improve the stability of dyes to all types of physico-chemical and physico-mechanical treatments and softness of prints, to ensure evenness of the print on a knitted fabric, as well as to exclude clogging of mesh patterns and sticking to the shafts of technological equipment.

The problem is solved by a composition for printing pigments of textile materials, including a pigment, a thickener, a binder and water, which contains Ruzin-14 as a binder, which is a multicomponent copolymer of butyl methacrylate with glycidyl methacrylate, isobornyl methacrylate, itaconic acid and styrene polymerization, obtained by the emulsion method as a thickener, Akremos-402 preparation, which is a copolymer of (meth) acrylic monomers obtained by emulsion polymerization , with the following content of components, g / kg:

Pigment 20-30 Ruzin-14 60-80 Akremos-402 80-100 Water up to 1000

Distinctive features of the invention are the use of Ruzin-14 as a binder, which is a multicomponent copolymer of butyl methacrylate with glycidyl methacrylate, isobornyl methacrylate, itaconic acid and styrene obtained by emulsion polymerization, and the use of Acremos-402 (a copolymer) as a thickener acrylic monomers obtained by emulsion polymerization. It is these distinctive features in combination with the known features that provide the following, very significant advantages:

- increase the resistance of colors to all types of physico-chemical and physico-mechanical treatments by 15-20%;

- increase the softness of prints on textile materials by 20%;

- ensuring the uniformity of prints on a knitted fabric;

- exception clogging mesh patterns and sticking the composition on the shafts of technological equipment.

In addition, the proposed composition allows to obtain the following advantages:

- the components of the composition are domestic drugs, which allows enterprises to reduce time and reduce financial costs associated with the delivery of raw materials and the search for suitable drugs;

- the composition is cheaper due to the smaller amount of the binder component, as well as the lower cost of both the binder and the thickener.

Information confirming the ability to reproduce the invention.

The composition contains the following components.

As pigments, you can use pigments traditionally used in pigment printing, for example, in the form of a water-borne paste finely dispersed organic pigment with a content of the main dye in the paste from 35 to 45% and a particle size of from 0.5 to 20 microns;

Ruzin-14 is a multicomponent copolymer of butyl methacrylate with glycidyl methacrylate, isobornyl methacrylate, itaconic acid and styrene, obtained by emulsion polymerization;

Akremos-402 is a copolymer of (meth) acrylic monomers obtained by emulsion polymerization, TU 2241-005-55856863-2001;

technical water.

The composition is prepared in a known manner traditionally used in pigment printing technology. To do this, a binder, a thickener and a pigment are introduced into the water with stirring in the required quantities. Printing of textile materials is carried out according to traditional technology using mesh patterns or engraved shafts.

Qualitative indicators of printed fabrics using the prototype and the inventive composition were determined equally as follows:

- color fastness to washing - according to GOST 9733.4 - 83;

- resistance to perspiration stains - according to GOST 9733.4 - 83;

- the resistance of the colors to friction - according to GOST 9733. 27-83.

The softness of the tissue was evaluated by the express method, determining the total (on the basis and the weft) angle of deviation from the horizontal of the fixed sample of 4 × 6 cm. The greater the angle of deviation corresponds to greater softness (Laboratory Workshop on Textile Materials Science / Ed. .: Legprombytizdat, 1986. - p. 261-264).

The color intensity of the prints (k / s) was judged by the magnitude of the reflection coefficient, determined on a Spekol-11 spectrophotometer.

Qualitative indicators of prints using the prototype and the claimed composition are shown in the table.
