Description
Известен способ получени окрашенных изделий из полиакрилонитрила и его сополимеров Путем введени в форМОвочный раствор растворимого в .нем окрашенного полимера (акрилонитрил-оксиэтилцеллюлозу, окрашенную кубовыми красител ми).A known method for the preparation of colored articles from polyacrylonitrile and its copolymers. By introducing into the formulation solution a soluble in the colored polymer (acrylonitrile hydroxyethylcellulose, painted by bottom dyes).
С целью получени высокопрочных окрасок предложено в качестве окрашиваюн1,его агента , примен ть красители, содержащне алифатическую альдегидную группу.In order to obtain high-strength colors, it has been proposed to use dyes containing an aliphatic aldehyde group as a dyeing agent, his agent.
Крашение осуш.ествл ют в течение 50- 60 мин .при температуре 80-90° С и значении рН 6-7 (добавка орга-нической кислоты). Из окрашенного таким образом полиакрилонитрила (ПАН) отливают пленкн и формуют волокна . Получают волокна с интенсивной окраской , весьма прочной к действию мокрых обработок, свету и трению.Dyeing dried over 50–60 minutes at a temperature of 80–90 ° C and a pH of 6–7 (addition of organic acid). From the polyacrylonitrile (PAN) so dyed, films are cast and the fibers are molded. Fibers are obtained with an intense color that is very durable to the action of wet treatments, light and friction.
Пример 1. В 2 об. ч. диметилформамида (ДМФА) раствор ют альдегидный краситель при комнатной температуре. К полученному раствору добавл ют 0,5 вес. ч. ПАН и 5 об. ч. ДМФА. Сосуд с раствором нагревают на кип щей водной бане в течение 1 час, после чего из окрашенного раствора ПАН отливают нленки -или формуют волокно но сухому способу.Example 1. In 2 vol. including dimethylformamide (DMF) dissolve the aldehyde dye at room temperature. To the resulting solution was added 0.5 weight. h. PAN and 5 about. h of DMF. The vessel with the solution is heated in a boiling water bath for 1 hour, after which from the colored solution of PAN the films are molded or the fiber is molded using a dry method.
Окрашенное изделие из ПАН мылуют при 100°С в течение 15 мин в растворе, содержащем 2 г/л нрепарате ТМС дл удалени не вступившего в реакцию с ПАН красител , промывают теплой и холодной водой и сушат.The painted product from PAN is soaked at 100 ° C for 15 minutes in a solution containing 2 g / l of TMS preparation to remove uncolored from PAN dye, washed with warm and cold water and dried.
Пример 2. В услови х примера 1 получают окрашенный раствор ПАН, использу вместо ДМФА этиленкарбонат. Из полученного раствора обычным способом формуют волокно .Example 2. Under the conditions of Example 1, a colored solution of PAN is obtained using ethylene carbonate instead of DMF. From the resulting solution in the usual way molded fiber.
Пример 3. В услови х примера 1 получают окрашенный раствор сополимера ПАН с метилметакрилато.м, использу в качестве растворител диметилсульфоксид. Из нолученного раствора обыч-ным способом формуют волокно .Example 3. Under the conditions of Example 1, a colored solution of a PAN copolymer with methyl methacrylate m is prepared using dimethyl sulfoxide as the solvent. A fiber is molded from the solution obtained in the usual way.
Предмет изобретени Subject invention
Способ получени окрашенных изделий из полнакрилонитрила и его саполимеров путем введени в формовочный раствор растворимого в нем окрашивающего агента, отличающийс тем, что, с целью получени высокопрочных окрасок, в качестве окрашивающего агента примен ют антрахиноновые красители, содержащие алифатическую альдегидную группу.The method of obtaining colored products from polnacrylonitrile and its sapolymers by introducing a coloring agent soluble in it into the molding solution, characterized in that, in order to obtain high-strength colors, anthraquinone dyes containing an aliphatic aldehyde group are used as a coloring agent.
