Description
промывка в трихлорэтилене при 20°С и сушка при 100-lloc. Результаты отбелки приведены в ,табл.1. Пример 3. Хлопчатобумажную ткань с исходной белизной 63% обраба тывают водным раствором ОП-10, отжимают до влажности 125% и отбеливают .раствором диметилсиленового эфира в перхлорэтилене с концентрацией актив ного хлора 3 г/л. Модуль ванны 30, т пература , продолжительность обработки б мин. После белени следует промывка в перхлорэтилене при 20°С сушка при 110-120С. Белизна после отбелки 87%. Ткань, отбеленна известнымспособом , имеет белизну 81%. Были проведены сравнительные испытани по удалению лигнина из отбеливаемых образцов. Как известно, лигнин содержитс в луб ных волокнах и в галочке , котора засор ет хлопчатобумажные издели . Данные испытаний приведены в табл. 2. Таким образом, изобретение обеспечивает высокую степень белизны целлюлозных текстильных материалов при минимальном потреблении воды . Таблица 1rinse in trichlorethylene at 20 ° C and drying at 100-lloc. The results of the bleaching are shown in Table 1. Example 3. 63% of the cotton fabric with the initial whiteness is treated with an OP-10 aqueous solution, pressed to a moisture content of 125% and bleached with dimethyl ether ether in perchlorethylene with a concentration of active chlorine of 3 g / l. Bath module 30, tons of temperature, processing time b min. After whitening, wash with perchlorethylene at 20 ° С and drying at 110-120С. Whiteness after bleaching 87%. The fabric, bleached by a known method, has a whiteness of 81%. Comparative tests were conducted to remove lignin from bleached samples. As is known, lignin is contained in bast fibers and in a tick, which clogs cotton products. Test data are given in table. 2. Thus, the invention provides a high degree of whiteness of cellulosic textile materials with minimal water consumption. Table 1
