The invention relates to the field of dyeing textile materials made of polyester fibers and can be implemented in the textile enterprises.

When the coloring of polyester fibers difficulties associated with the peculiarities of their structure: the presence of significant amounts of oligomers, the high order structure, the hydrophobic nature of the fiber material.

The most widely used periodic methods of dyeing polyester materials in the autoclave under pressure at a temperature of 120-140°C. These technologies are characterized by high energy intensity and structural complexity of the equipment, so more attention is paid to the technology of dyeing at lower temperatures.

Method of dyeing polyester yarn processing freshly formed filaments in an aqueous dyeing bath disperse dyes when heated and the tension of less than 0.3 g/Tex carried out in two stages at a temperature of 100.5-105°C: dyeing and dyeing with stretching. Amorphous polymer strands evenly saturated with dye and at the same time the thread is drawn 1.5-10 times [the Application for the invention of the Russian Federation 94031444, 1996, IPC D06P 3/54, D06P 5/00]. The disadvantage of this method is limited by its use in this way it is possible to dye polyester fibers and bundles in their production process.

Found wide application period is systematic and continuous methods of dyeing textile materials of polyester fibers with the use of stimulating agents. In continuous methods of dyeing of polyester yarn dye bath contains a complex composition of organic and inorganic compounds. For example, offer [RF Patent 2064026, 1996, IPC D06P 3/36] to use the following composition (g/l): disperse dye 5-40, urea 100-150, calcium chloride or lithium chloride, 5-10% of the amount of urea thickener 10-20, water up to 1000. The composition can improve the yield of the dyes on the fiber, the use of disperse dyes with low and medium resistance to sublimation. The disadvantages of continuous methods of dyeing are the release of toxic volatile substances by heat-setting, the inability to paint knitted fabric, and fabric from a blend of polyester fibers with the fibers undergoing structural changes during heat-setting temperature of 200-220°C.

Periodic methods of dyeing allow you to process any of textile materials (yarn, tow, fabric, knitted fabrics and products) and to eliminate the heat-setting stage. In the application for the invention 2006016711 JP IPC D06P 3/54, D06P 1/44, D06P 5/20, D06P 1/90, D06P 3/34, D06P 1/00 describes a method of dyeing polyester fibers periodic way composition comprising a polar organic solvent from the following range: methanol, ethanol, isopropyl alcohol, butanol, benzyl alcohol, acetone, acetophenone, N-methyl-2-pyrrolidone, matile Ilkeston, dimethyl sulfoxide, dimethylformamide, ethylene glycol and acetonitrile. Good indicators color finishing of polyester materials disperse dyes at temperatures not higher than 100°C. allow to obtain the following intensifiers: 1-chloro-2-naphthol, anilide salicylic acid, benzyl acetate [Patent 66047 And Ukraine 2004 IPC D06P 1/16].

The closest analogue to the claimed invention is "a Mixture of intensifiers for dyeing polyester materials: N-alkylphthalimide and aromatic ether or another" [patent 49994089 USA 1991 8/574]. As an intensifier, it is recommended to use a mixture of components (I) and (II) in a weight ratio of 0.5 to 12:1. Component (I) is an N-alkylphthalimide with a linear or branched radical with a chain length of C1-C6. Component (II) is an aromatic ether complex (for example, benzoic ether, methylpentynol, salicylic acid), or W (for example, ester of terephthalic and phthalic acid), or carbonate (e.g., diphenylcarbonate), or other ether (for example, diphenyl and ditallow). The alcohol components of the esters may be the remains of aliphatic alcohols with a chain length of C1-C6, phenol and benzyl alcohol.

A mixture of intensifiers contains, wt.%:

1) 40-90 component (I), namely 50-75 N-alkylphthalimide with linear or branched radicals is scrap with chain length With 3-C5,

2) 8-58 component (II), namely 10-40 alkylphenolate or benzyl ester of benzoic, methylpentynol, terephthalic, phthalic and salicylic acids, or diphenylcarbonate, or diphenyl, or detailpage ether;

3) 2-30 emulsifier; namely 5-20 mixture 15-30 of ethylene oxide to castor or legumes, soy oil, 5-50 mol of ethylene oxide and/or propylenoxide in a fatty alcohol with a chain length of C16-C22, op or Nonylphenol or phenylphenol, salts of alkali metal, salts of alkaline-earth metal, ammonium salts or salts of diethanolamine in dodecylbenzensulfonate.

4) 0-10 solvent.

The disadvantage of this composition is an unpleasant odor and toxicity of the used organic substances that worsen the working conditions of staff in production and reduces the comfort of the use of textiles. In addition, the waste water containing an organic solvent, have a detrimental effect on aquatic and generally not suitable for reuse. Technology of dyeing of polyester materials with disperse dyes using a mixture of intensifiers (N-alkylphthalimide and aromatic ether) comprises regulating the pH of dye bath using acetic acid treatment at 98°C are within 60 minutes

The technical result saleemul the solution is to eliminate these disadvantages, namely the use of non-lethal and environmentally safe compounds in the composition in the dyeing of polyester materials with disperse dyes at a temperature of 98-100°C while maintaining performance colour finish (intensity, rowmote and strength of color to washing, friction, sitopaladi) and the simplification of dyeing reduced processing time and exceptions pH control.

This object is achieved due to the fact that the composition for dyeing textile materials of polyester staple fibers, comprising a disperse dye lightfastness, an intensifier, water, characterized in that as an intensifier is used Quaternary ammonium salt of General formula:

where R1- CH3With2H5;

R2- CH2With6H5C12H25C13H27C14H29With15H31With16H33;

X Is Cl, Br.

in the following ratio of ingredients (g/l):

disperse dye lightfastness0,5-1
an intensifier1,0-5,0
waterthe rest of it.

Significant difference is is use as an intensifier Quaternary ammonium salt, having amphiphilic properties, in combination with a disperse dye lightfastness.

The claimed composition does not require the use of additional substances to obtain rawsonrenowned colors as Quaternary ammonium salt having one of the radicals-CH2C6H5or-C12H25or-C13H27or14H29or15H31or-C16H33play the role of both the equalizer and the intensifier when dyeing textile materials of polyester fibers dispersed fade resistant dyes. Declare intensifiers for dyeing textile materials of polyester fibers are environmentally safe substances. It is known that such Quaternary ammonium salts are added to cosmetic compositions for hair care as degreasing component [RF Patent 2350312 2009 IPC AC 8/04, A61Q 5/06, RF Patent 2212224 2003 IPC AC 7/06], chloride of triethylenediamine is interphase catalyst in wastewater from organochlorine compounds [RF Patent 2187464, 2002, IPC C02F 1/70, C02F 103:36]. Samples dyed using featured Quaternary ammonium salts, are characterized by intense, smooth and solid colors. Pre-treatment of the textile material before dyeing is not required, even ertinya ammonium salt such structures play the role of catalyst in the hydrolysis of cyclic oligomers [Chemical fiber. No. 6, 2006. P.17-20]. Residual bath after dyeing reusable after recharge concentrated dye solutions and the intensifier to the required level.

The essence of the technical solutions disclosed in the table.

Sample No. 1-10, 13, 16, 19, 22, 25, 30, 32, 33, 34 processed within 40 min, the samples№№11, 15, 21, 29, 31 - within 35 minutes, rest for 45 minutes

The painted samples were subjected to tests according to GOST R ISO 105-E03-99, 105-E02-99, GOST 28692-90, 9733-83, GOST 28692-90. The intensity and roveto coloring the dyed samples were evaluated on spectrocolorimeter "Color 15" firm "Gretag Macbeth".

The resulting test parameters correspond to the required level. The table below shows the indicators color finish, illustrating the most stimulating effect of Quaternary ammonium salts: intensity, rowdata dyeing and color fastness to washing, to friction, to sitopaladi.
