Description

Как известно полиакрилнитрильнос волокно ннтрои не окрашиваетс  большинством кислотных красителей.As is known, polyacrylonitrile fiber is not dyed with most acid dyes.

Известные способы крашени  полиакрилнитрильных волокон осундествл ютс  в присутствии солей меди. Наиболее распространенным способом крашени   вл етс  медноионный, при котором крашение производитс  в присутствии ионов одновалентной меди.Known methods for dyeing polyacrylonitrile fibers are ozonized in the presence of copper salts. The most common dyeing method is copper-ion, in which dyeing is carried out in the presence of monovalent copper ions.

Ионы одновалентной меди образуютс  в красильной ванне различными способами: либо воздействием различных восстановителей на двухвалентную медь, либо введением органических комплексных соединений одновалентной меди, например комплекс тетрасалицилонитрила с хлористой медью. Однако эти способы весьма громоздки и дороги.Monovalent copper ions are formed in the dye bath in various ways: either by exposure of bivalent copper to various reducing agents, or by introducing organic complex compounds of monovalent copper, for example, a complex of tetrasalicylonitrile with copper chloride. However, these methods are very cumbersome and expensive.

Иредлагаемый способ крашени  полиакрилнитрильного волокна отличаетс  те.м, что в качестве солей меди примен ют соли двухвалентной меди, например медный купорос.The proposed method for dyeing polyacrylonitrile fiber is different in that the salts of bivalent copper, such as copper sulfate, are used as copper salts.

И р и м е р. Дл  крашени  и.итрона берут (от веса волокна) 4-10% медного купороса (CuSO4. 5И2О), 4% красител , модуль ванны 1:50, 1:75, процесс крашени  производ т по следующей технологии: волокно погружают в раствор, содержанцтй краситель и медный купорос, раствор постепенно нагревают до 95° и провод т крашение в течение 1 час, после чего волокно выдерживают в остываюш,ем растворе в течение 15-30 мин.And p and meer. For dyeing and nitron, 4-10% of copper sulfate (CuSO4. 5И2О), 4% dye, bath module 1:50, 1:75 are taken (by weight of fiber), the dyeing process is performed according to the following technology: the fiber is immersed in a solution, containing dye and blue vitriol, the solution is gradually heated to 95 ° and dyeing is carried out for 1 hour, after which the fiber is kept in a cooling solution for 15-30 minutes.

Иосле выстаивани  при температуре 40-60° окрашенное волокно вынимают из красильного раствора и промывают .холодной, а затем теплой водой.After standing at a temperature of 40-60 °, the dyed fiber is removed from the dye solution and washed with cold and then warm water.

Предмет изобретени Subject invention

Способ крашени  полиакрилнитрильного волокна в присутствии солей меди, отличающийс  тем, что, с целью удешевлени  и упрощени  процесса, в качестве солей меди .примен ют соли двухвалентной меди, например медный купорос.The method of dyeing polyacrylonitrile fiber in the presence of copper salts, characterized in that, to reduce the cost and simplify the process, salts of copper are used as copper salts, such as copper sulfate.
