ЙзЁестнен способ крашени  №Дрофобны)( Химических, например ацетатных, волокон в красильной вание, содержащей Дисперсный бензимидазоловой краситель.The Joestnen method of dyeing is Drophobic) (Chemical, for example acetate, fibers in dye containing Dispersed Benzimidazole dye.

Получаемые окраски обладают ловыШейНой светостойкостью, но из-за .присутстви  азогруппы в молекуле не термостойки.The resulting colors have a fishing light resistance, but because of the presence of the azo group in the molecule is not heat resistant.

С целью получени  росных и высокопрочных окрасок предлагаетс  в качестве красител  использовать динитропроизводное ариламинобензимидазола общей формулыIn order to obtain dewy and high-strength colors, it is proposed to use dinitro derivative arylaminobenzimidazole of the general formula as a dye

Пример 2. При крашении TIC термозольному способу .краситель (50 г/л) затирают с пропиленкарболатом (100 г/л), разбавл ют гор  чей водой (60-70°С) и лри перемешивании добавл ют загуститель - альгинат natpn (1г/л).Example 2. When dyeing the TIC with the thermosol method, the dye (50 g / l) is rubbed with propylenecarbolate (100 g / l), diluted with hot water (60-70 ° C) and the thickener - alginate natpn (1g / l).

Пропитку красильвым раствором при 90°С гфовод т в течение 1 мин, отжимают, сушат гор чим воздухом при 80-100°С, термофиксируют при 160-190°С в течение 1-2 мин, охлаждают на воздухе, промывают холодной водой, обрабатывают раствором ОП-10 (1 г/л) при 70°С, промывают теплой водой и сушат.The impregnation with the dye solution at 90 ° C is guided for 1 min, wrung out, dried with hot air at 80-100 ° C, thermofixed at 160-190 ° C for 1-2 min, cooled in air, washed with cold water, treated solution OP-10 (1 g / l) at 70 ° C, washed with warm water and dried.

Пример 3. Образец ацетатной ткани окрашивают в ванне, содержащей 5% красител , например 4,6-динитро-5-фениламинобензимидазола , растворенного в трихлорэтилеие, 1при 80°С в течение 30 мин. Затем образец отжимают , промывают в трихлорэтилене и сушат.Example 3. A sample of acetate fabric is stained in a bath containing 5% of a dye, for example 4,6-dinitro-5-phenylaminobenzimidazole, dissolved in trichloro-ethylene, 1 at 80 ° C for 30 minutes. Then the sample is drained, washed in trichlorethylene and dried.

Предлагаемыми красител ми можно окрашивать и другие гидрофобные химические волокна , например полиакрилонитрильные, получа  высокопрочные окраски.Other hydrophobic chemical fibers, for example polyacrylonitrile, can be dyed with dyes to obtain high strength colors.
