Description
Известен способ крашени шерст ных волокон кислотными красител ми , содержащими хромовый колгилекс, в котором на один атом хрома приходитс 2 молекулы красител или одна молекула красител и одна молекула комплексообразующего стабилизатора.The known method of dyeing wool fibers with acid dyes containing chromium colgilex, in which there are 2 dye molecules or one dye molecule and one complexing stabilizer molecule per chromium atom.
Использование, с целью равномерных окрасок шерст ных волокон в смешанных ткан х, добавок - смеси полигликолевых эфиров жирных кислот и полиосновных аминокарбоновых кислот или их замещенныч известно.The use, for the purpose of uniform dyeing of wool fibers in mixed fabrics, of additives is a mixture of polyglycolic esters of fatty acids and polybasic aminocarboxylic acids, or their substitutes are known.
Также известен способ обработки шерст ных и полиамидных волокои , с целью повышени прочности окраски, кислотными красител ми, до или после крашени растворами триэтиленимида фосфорной и тисфосфорной кислот.A method of treating wool and polyamide fibers is also known, with the aim of increasing the color strength with acid dyes, before or after dyeing with solutions of phosphoric triethylimide and histophosphoric acid.
При применении органических растворителей по непрерывному л периодическому способу не всегда удаетс достичь равномерного крашени особенно красител ми, содержащими хромовый комплекс 1:2, так как при крашении на поверхности волокна сорбируютс капли эмульсии растворител с большой концентрацией красител , отчего происходит быстра местна сорбци красител , привод ща к неравномерной окраске.When using organic solvents in a continuous mode, it is not always possible to achieve uniform dyeing with especially dyes containing a 1: 2 chromium complex, because when dyeing, emulsion droplets of a solvent emulsion with a high dye concentration are sorbed on the fiber surface, which causes fast local sorption of the dye drive conductive to uneven color.
Предложенный способ отличаетс от известных тем, что предварительную обработку ткани ведут эмульсией растворител , состо щего из смеси моноэфиров жирных кислот, ксилитана и полигликолевых эфиров этих соединений.The proposed method differs from the known ones in that the pretreatment of the fabric is carried out with an emulsion of a solvent consisting of a mixture of monoesters of fatty acids, xylitane and polyglycol ethers of these compounds.
По предлагаемому способу окрашиваемый материал предварительно плюсуетс в эмульсии растворител и затем без высущивани пер водитс в красильную ванну. При применении этого способа эмульси растворител сорбируетс и равномерно распредел етс на волокне . При перенесении ткани в красильную ванну происходит постепенное растворение красител , наход щегос в водном растворе в растворителе , нанесенном на волокно. При этом, как по непрерывному, так и поAccording to the proposed method, the material to be painted is preliminarily plus in the emulsion of the solvent and then, without drying, the feather is led into the dyebath. When using this method, the solvent emulsion is sorbed and evenly distributed on the fiber. When the fabric is transferred to the dye bath, the dye, which is in an aqueous solution in a solvent applied to the fiber, gradually dissolves. In this case, both in continuous and in
