Description

Изобретение относитс  к текстильной промьшшенности, а именно к спосо бам обработки оптическими отбеливател ми тканей из смеси целлюлозного и полиэтилентерефталатного волокон, напечатанных тиоиндигоидньми красител ми , с целью повьппени  белизны белого фона тканей.The invention relates to the textile industry, in particular, to the processing of optical bleach fabrics from a mixture of cellulose and polyethylene terephthalate fibers printed with thioindioid dyes in order to whiten the white background of the fabrics.

Цель изобретени  - уменьшение закрашивани  белого фона за счет снижени  миграции красител .The purpose of the invention is to reduce the white staining by reducing the dye migration.

Миграци  красител , вызывающа  закрашивание белого фона, возникает в услови х tepмooбpaбoтки ткани, например, после нанесени  на нее оптического отбеливател , в процессе термостабилизации таких тканей и других операций, св занных с термообработкой.Dye migration, which causes a white background to stain, occurs under the conditions of a thermal treatment of the fabric, for example, after applying an optical bleach on it, in the process of thermal stabilization of such fabrics and other heat-treating operations.

Примеры 1 и 2 (по известно му способу). Ткань из смеси хлопка и полиэтилентерефталатных волокон после печати тиоиндигоидными красител 130962Examples 1 and 2 (by the known method). Fabric from a mixture of cotton and polyethylene terephthalate fibers after printing with thioindigoid dyes 130962

Vm по ронгалитно-потащному способу пропитьгоают водным раствором, содержащим оптический отбеливатель 10 г/л, сушат при , термофик- 5 сируют при 200 С,According to the rongalite-sweeping method, Vm is passed through with an aqueous solution containing an optical brightener of 10 g / l, dried at, heat-fixed at 200 ° C,

Примеры 3-5. Обработку ведут как в примерах 1-2, но в раствор дл  пропитки ввод т препарат стеа- рокс 6 или стеарокс 920 на основе смеси оксиэтилированных жирных кислот фракции C|.j-C| со средней степенью оксизтилировани  6 или 20 соответственно .Examples 3-5. Treatment is carried out as in Examples 1-2, but a stearox 6 or stearox 920 preparation based on a mixture of ethoxylated fatty acids of fraction C | .j-C | with an average degree of oxidation of 6 or 20, respectively.

Во всех примерах в качестве опти- 5 ческого отбеливател  используют производные оксазола формулы:In all examples, oxazole derivatives of the formula are used as an optical bleach:
