Abstract
Изобретение относитс к области технологии химической обработки текстильных изделий, а именно к составам дл отбеливани хлопчатобумажных текстильных материалов . Изобретение обеспечивает упрощение процесса белени и снижение расхода реагентов за счет того, что водный состав дл отбеливани хлозпчатобумаж- ных тканей содержит 4-8 г/л пероксида водорода , 4-6 г/л гидроксида натри , 0,5-1 г/л неионогенного смачивател и 2-5 г/л смеси глиоксал с карбоновыми неорганическими кислотами и нитратом лити 1 таблThis invention relates to the field of chemical processing technology for textiles, in particular, compositions for bleaching cotton textiles. The invention provides a simplified whitening process and a reduction in reagent consumption due to the fact that the aqueous composition for bleaching cotton fabrics contains 4-8 g / l of hydrogen peroxide, 4-6 g / l of sodium hydroxide, 0.5-1 g / l of non-ionic wetting agent and 2-5 g / l of a mixture of glyoxal with carboxylic inorganic acids and lithium nitrate 1 tab.

Изобретение относитс к технологии химической обработки текстильных изделий , а именно к составам дл отбеливани хлопчатобумажных текстильных материалов .This invention relates to a technology for the chemical treatment of textiles, namely, compositions for bleaching cotton textiles.
Цель изобретени - упрощение процесса и снижение расхода реагентов.The purpose of the invention is to simplify the process and reduce reagent consumption.
Пример 1 (сравнительный). Хлопчатобумажную б зь обрабатывают при 98- 100°С 60 мин раствором, содержащим, г/л:Example 1 (comparative). Cotton bast is treated at 98-100 ° C for 60 minutes with a solution containing, g / l:
Перекись водорода Гидроокись натри Неионогенный смачиватель ОП-10 на основе оксиэтилирован- ного алкилфенола Несиликатный стабилизатор перекиси водорода - полиэтилен- оксид с мол.М. 20000Hydrogen peroxide Sodium hydroxide OP-10 non-ionic wetting agent based on ethoxylated alkylphenol Non-silicate hydrogen peroxide stabilizer - polyethylene oxide with mol.M. 20,000

Примеры 2-5. Обработку ткани провод т по примеру 1, но в качестве несиликатного стабилизатора используют смесь глиоксал с карбоновыми, неорганическими кислотами и нитратом лити , представл ющего собой отходы глиоксанового производства по ТУ 6-09-3530-79 отбираемые на конечной стадии очистки глиоксал , содержащую , мас.%:Examples 2-5. Fabric treatment is carried out according to Example 1, but as a non-silicate stabilizer a mixture of glyoxal with carboxylic, inorganic acids and lithium nitrate is used, which is a waste of glyoxane production according to TU 6-09-3530-79, glyoxal containing .%:
