Description
Известные способы крашени вискозных волокон лед ными красител ми не обеспечивают ровную окраску волокна.Known methods of dyeing viscose fibers with ice dyes do not provide an even color of the fiber.
В описываемом способе этот недостаток устранен благодар тому, что в вискозу добавл ют щелочной раствор азотола, полученное волокпо обрабатывают парами аммиака или слабым раствором щелочи, после чего волокно обрабатывают раствором .1,иазосоставл юн,ей.In the described method, this disadvantage is eliminated due to the fact that an alkaline solution of nitrogen is added to the viscose, the obtained fiber is treated with ammonia vapors or a weak alkali solution, after which the fiber is treated with solution.
П р и м е 1 1. 2 г азотола А раствор ют при 5о - 65° в 100 6%-пого раствора едкого натра. Полученный щелочной раствор азотола А ввод т в вискозу обычного состава в количестве 3 - от содержащейс в вискозе альфацеллюлозы .EXAMPLE 1 1. 2 g of Nitol A is dissolved at 5 ° -65 ° in 100% 6% sodium hydroxide solution. The resulting alkaline solution of azotaol A is injected into a viscose of the usual composition in an amount of 3 from the alphacellulose contained in the viscose.
Сформированное в обычной кис .тоткой ванне вискозное волокно промывают, отжимают и обрабатывают парами аммиака, после чего волокно обрабатывают раствором диазосоставл ющей.Viscose fiber formed in an ordinary acidic bath is washed, drained and treated with ammonia vapors, after which the fiber is treated with a diazo-component solution.
В зависимости от примен емого алгина получают вискозное волокно различной окраски.Depending on the algin used, viscose fiber of various colors is obtained.
И р н мер 2, Процесс крашени ведут, как указано в примере 1, но вместо обработки парами аммиака примен ют обработку 0,25 Al-ным раствором едкого натра в течение 1 - 5 минут, затем волокно отжимают , высушивают и далее обрабатывают j acTBopoN диазосоставл юnieii .And pn 2, The process of dyeing is carried out as indicated in example 1, but instead of treatment with ammonia vapors, treatment with a 0.25 Al solution of sodium hydroxide is used for 1–5 minutes, then the fiber is drained, dried and then treated diazosomes youth.
