Description

Вискозный шелк, окрашенный в массе кубовыми красител ми, получают в насто ш;ее врем  путем введени  в вискозу суспензий этих красителей, полученных размолом в коллоидной мельнице в присутствии воды и диспергируюш,их веществ .Viscose silk, dyed in bulk by vat dyes, is currently produced, its time by introducing into viscose suspensions of these dyes, obtained by grinding in a colloid mill in the presence of water and dispersing, their substances.

Недостатком этого способа  вл етс  то, что он не позвол ет получать  рких и сочных окрасок и полиостью использовать крас щую способность указанных красителей.The disadvantage of this method is that it does not allow to obtain bright and rich colors and to completely use the dyeing power of these dyes.

Установлено, что вышеуказанные недостатки можно устранить, если кубовые красители вводить в вискозу в форме золей, получаемых осаждением щелочных растворов лейкосоединепий указанных красителей кислотой в присутствии диспергаторов , иаиример, сульфитцеллюлозного экстракта, и окислителей, например, перекиси водорода. При формовании волокна высокодисперсный золь кубового красител  быстро восстанавливаетс  в осадительной ванне в лейкосоединение (под действием образующихс  в этой ванне восстановительных веществ ), которое снова окисл етс It has been established that the above disadvantages can be eliminated if vat dyes are introduced into viscose in the form of sols obtained by precipitating alkaline solutions of leuco-compounds of these dyes with acid in the presence of dispersants, iarymer, cellulose sulfite extract, and oxidizers, for example, hydrogen peroxide. During fiber spinning, the highly dispersed vat dye sol is rapidly reduced in a precipitation bath to a leuco compound (under the influence of reducing substances formed in this bath), which is again oxidized.

при последующей промывке волокна.during the subsequent washing of the fiber.

Пример. I кг кубового  ркозеленого Ж, 0,5 кг гидросульфита и 0,5 кг едкого натра в пересчете на 100 % раствор ют в воде, восстанавливают при нагревании до образовани  лейкосоединени , затем добавл ют 1,5 кг сульфитцеллюлозного экстракта, 0,8-1,0 кг уксусной кислоты в пересчете на 100 % и 1,0-1,5 кг перекиси водорода 30%.Example. I kg vodka green g, 0.5 kg hydrosulfite and 0.5 kg sodium hydroxide, calculated as 100%, are dissolved in water, reduced by heating to form a leuco compound, then 1.5 kg sulphitecellulose extract is added, 0.8-1 , 0 kg of acetic acid in terms of 100% and 1.0-1.5 kg of hydrogen peroxide 30%.

Полученный таким образом золь смещивают с вискозой в соотношении I : 1 и ввод т в основную массу вискозы до пр дени .The sol thus obtained is displaced with viscose in the ratio of I: 1 and introduced into the bulk of the viscose before the spinning.

Предмет изобретени Subject invention

Способ получени  вискозного щелка, окращенного в массе кубовыми красител ми, вводимыми в вискозу до пр дени , отличающийс  тем, что, с целью иовыщени   ркости окрасок, указанные красители ввод т в вискозу в форме золей, полученных осаждением щелочных растворов их лейкосоединений кислотой в присутствии диспергаторов , например, сульфитцеллюлозного экстракта, и окислителей , например, перекиси водорода.The method of obtaining viscose lye, shredded in bulk by vat dyes introduced into viscose before spinning, characterized in that, in order to increase the brightness of the dyes, these dyes are introduced into viscose in the form of sols obtained by precipitating alkaline solutions of their leuco-compounds with acid in the presence of dispersants , for example, sulfitellulose extract, and oxidizing agents, for example, hydrogen peroxide.
