Description
Примен емые в насто щее врем серые окраски мехов (козлик, овчина ) отличаютс невысокой светоирочностью . Это же, хот и в несколько меньшей степени, относитс и к окраске их в коричневый цвет.The currently used gray colors of the furs (goat, sheepskin) are characterized by a low luminosity of light. The same, although to a somewhat lesser extent, also applies to their coloration in brown.
Уже известно крашение мехов анилином по следуюшей схеме: обработка кислым раствором бихромата - анилинова ванна.The dyeing of furs with aniline is already known according to the following scheme: treatment with an acidic solution of bichromate — aniline bath.
Авторами установлено, что при добавлении в анилиновую ванну диметиланилина можно получить светопрочные окраски в серый и коричневый цвета мерлушки и овчины. При этом в первом случаенеобходима восстановительна (гипосульфитна ) обработка после анилиновой ванны.The authors found that when dimethylaniline is added to the aniline bath, it is possible to obtain lightfast colors in gray and brown colors of the merlushka and sheepskin. In this case, in the first case, reductive (hyposulphite) treatment is required after the aniline bath.

Пример 2. Методика крашени в серый цвет.Example 2. The method of dyeing in gray.
В отличие от методики крашени в коричневый цвет после отжима (операции 4) вводитс операци восстановлени , а концентраци диметиланилина снижаетс до 0,5i-1,0 г/л Восстановление проводитс следующим образом: отжатые шкуры обрабатываютс в течение 4-8 час. при 25° в ванне, содержащей б г/л гипосульфита,- 1,5-4,0 г/л серной кислоты и 60 г/л поваренной соли.In contrast to the dyeing brown technique, after extraction (step 4), a reduction operation is introduced, and the concentration of dimethylaniline is reduced to 0.5i-1.0 g / l. Recovery is carried out as follows: pressed skins are treated for 4-8 hours. at 25 ° in a bath containing b g / l of hyposulfite, 1.5-4.0 g / l of sulfuric acid and 60 g / l of sodium chloride.

Способ крашени мехов анилином с предварительной обработкой шкур минерально кислым раствором бихромата н последующей обработкой раствором анилиновой соли, отличаюш;ийс тем, что дл получени светопрочной окраски в коричневый и серые цвета в анилиновую ванну ввод т диметиланилии, например, в виде сульфата, 2. Прием выполнени способа пэ п. 1, о т л и ч а юш; и и с тем, что при крашении в серый цвет шкуры после анилиновой ванны подвергают восстановительной обработке кнслым раствором гипосульфита.77 No. 60326 .- 2 Subject of the invention 1. The method of dyeing fur with aniline with pretreatment of hides with an acidic mineral solution of bichromate and subsequent treatment with an aniline salt solution; , for example, in the form of sulphate, 2. Acceptance of the implementation of the method of PE of clause 1, about tl and h; yush; and with the fact that when dyeing in gray the color of the skin after the aniline bath is subjected to a reducing treatment with hypersulfite solution.
