The invention relates to chemical technology of textile materials, namely, compositions for coloring textile materials.

The level of technology.

It is known that the printing of textile materials pigments is carried out by applying printing ink and fixing it at a temperature of 170-180C for 3 minutes. The composition of the printing ink includes a pigment, a thickener, drugs, contributing to the consolidation of the pigment to the textile material, namely setco - and film-forming polymers, and various additives such as softeners, clamps, catalysts and other

As sethaputra polymers used methylol derivatives of urea and triazine. They are in the presence of a catalyst to form covalent bonds between the macromolecules of cellulose, but with pigment and film-forming polymer.

As film-forming polymers are used derivatives of acrylic acid, such as latexes and emulsion polymers. Film-forming polymers are introduced in order to give improved properties to textile materials such as fullness, quality, softness, etc. In some cases, film-forming polymers contribute to improving the strength characteristics of color to various physico-chemical and mechanical treatments.

Since the viscosity of aqueous solutions of setco and incobrasa polymers insufficient to obtain a printing ink with the necessary technological properties, in the printing ink is injected thickener. However, the thickener in the places of drawing ink makes the fabric stiff neck due to fixing it on the textile material with a binder. When printing pigments most commonly used emulsion Segundo type oil-in-water, which is obtained by mechanical mixing of white spirit in an aqueous solution of emulsifier (Benbelkacem, Tudzharov, Mencarelli. "Physico-chemical basis of the finishing processes of production". M: "Light and food industry", 1982, 280; Benbelkacem, Ibelieve, Heinegard and other Progress of engineering and technology printing of fabrics. M: "Light industry", 1980, 264).

Known composition for printing textile materials pigments, containing, g/kg:

Pigment50-60
Latex SCS-HP130
Metasin100
Ammonium chloride4
Emulsion sagasti based on white spiritUp to 1 kg

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

Metasin used as a crosslinking agent for fixing the pigment particles on the textile material by forming a spatial grid of the polymer and covalent bonds between the drug and cellulose.

Ammonium chloride catalyzes the formation of spatial grid (Benbelkacem, Tudzharov, Mencarelli. "Physico-chemical basis of the finishing processes of production". M: "Light and food industry", 1982, 280; B.N. Melnikov, Ibelieve, Heinegard and other Progress of engineering and technology printing of fabrics. M: "Light industry", 1980, 264).

However, the composition is a fire hazard, with poor sanitary conditions.

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

Pigment80
HEMUCRYL M200
Emugel P20
Glycitin20
Softner12
Ethylene glycol15
Stearic 6 (1:3 with water)20
Ammonium sulfate (1:3 with water)10
Sagasti based on acrylic polymersUp to 1 kg

In this part of HEMUCRYL M and HEMUCRYL P play the role of setco - and film-forming polymers; ammonium sulfate catalyst; Glikin, ethylene glycol, stearic 6, softner perform the role of additives that contribute to the formation of the textile material is more transparent soft polymer films and more durable fastening it to the textile material (Benbelkacem, Ibelieve, Heinegard and other Progress of engineering and technology printing of fabrics. M: "Light industry", 1980, 264).

However, the composition is difficult to prepare because of the multi-component nature, does not provide sufficient strength of dyed printed fabrics to the dry and wet friction and net scores templates or sticks to the rollers in the dryer section of the machine, which leads to the shutdown.

The closest to the invention by the combination of essential features is the composition for printing textile materials [a Collection of papers //Herr Perkuhn "archival Pigment print, April 1996]: containing, g/kg:

Pigment20
Luprinol RE5
Lutensol HEF25
Helizarin binder UDR120
WaterUp to 1000

Helizarin binder is a flowable aqueous dispersion of film-forming, samoszhimayuschihsya copolymers based on acrylate, which have very good storage stability.

Lutensol HEF - synthetic thickener based on esters of (meth)acrylic acid.

Luprinol RE acts as the emulsifier, which contributes to a stable and thin distribution of solids (binder, pigments, softeners) in the printing ink.

However, the composition has the following disadvantages:

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

- low soft prints on textile materials;

- composition for printing on the Jersey gives marriage: neronet print ("cloudy", "restless print");

- possible clogging of the mesh templates and build-up on the ramparts of technological equipment.

The essence of the invention.

Object of the invention is search composition for printing pigments textile mother of the crystals, comprising a pigment, a thickener, a binder and water, which would improve the sustainability of colors to all kinds of physico-chemical and physico-mechanical treatments and soft prints, to ensure roveto imprint on a knitted cloth, and also to eliminate clogging of the mesh templates and build-up on the ramparts of technological equipment.

The problem is solved by a composition for printing pigments textile materials, comprising a pigment, a thickener, a binder and water, in which the binder contains a drug Ruzin-14, which represents a multicomponent copolymer of butyl methacrylate with glycidylmethacrylate, isobutylacetate, taconova acid and styrene, obtained by the method of emulsion polymerization, as a binder - drug Gramos-402 representing a copolymer of (meth)acrylic monomers, obtained by the method of emulsion polymerization, with the following content of components, g/kg:

Pigment20-30
Ruzin-1460-80
Gramos-40280-100
Waterup to 1000

Distinctive features of izaberete the Oia are using as a binder of the drug Ruzin-14, representing a multi-component copolymer of butyl methacrylate with glycidylmethacrylate, isobutylacetate, taconova acid and styrene, obtained by the method of emulsion polymerization, and use as a thickener - drug Gramos-402 representing a copolymer of (meth)acrylic monomers, obtained by the method of emulsion polymerization. These features in conjunction with the known characteristics provide the following significant advantages:

- increase the resistance of paints to all kinds of physico-chemical and physico-mechanical treatments on 15-20%;

- increase the smoothness of the prints on textile materials 20%;

- ensuring roveto prints on knitted cloth;

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

Moreover, the proposed structure provides the following advantages:

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 products;

- composition cheaper due to the smaller amount of the binder component, and a lower cost and a binder, and a thickener.

Information confirming the prob is the possibility playback of the invention.

The composition contains the following components.

As pigments can be used pigments traditionally used in pigment printing, for example, in the form of a water soluble paste thin-dispersed organic pigment content of the basic dye in the paste from 35 to 45% and a particle size of from 0.5 to 20 microns;
