Description
(54) ПРЯДИЛЬНЫЙ РАСТВОР(54) SPINAL SOLUTION
CymnocTii изобретени заключаетс в том, что небольшое количество стабилизатора (1) ввод т непосредственно в пр дильный раст вор ацетата целлюлозы, используемый дл . формовани ацетатного волокна или пленки 5 по сухому или мокрому способу.The CymnocTii of the invention is that a small amount of the stabilizer (1) is introduced directly into the spinning solution used for cellulose acetate. forming an acetate fiber or film 5 using a dry or wet method.
Пример. В 4%-ном растворе ацетата целлюлозы в диметилформамиде раствор ют светостабилизатор в количестве О,11О% от веса ацетата целлюлозы. Смесь пе- № ремешивают до полного растворени обоих компонентов. Из полученного раствора отли вают пленки которые подвергают УФ-облучёнию . Полученные указанной обработкой пленки окрашиваютс в зависимости от со- 18 держани стабилизатора от слегка фиолетового до черного цвета.Example. In a 4% solution of cellulose acetate in dimethylformamide, the light stabilizer is dissolved in an amount of 0.11% by weight of cellulose acetate. The mixture of primer is stirred until both components are completely dissolved. Films that are subjected to UV irradiation are cast from the solution obtained. The films obtained by this treatment are colored according to the content of the stabilizer from slightly violet to black.
В таблице приведены соответствующие сравнительные данные изменени удельнойThe table shows the corresponding comparative data for changes in the specific
в зкости растворов из пленки исходной ацетил целлюлозы и ацетата целлюлозы содержащие 0,1-10% предложенного стабилизатора до и после облучени ртутно-кварцевой лампой ПРК-2 в течение 2 О час.viscosities of solutions from a film of cellulose acetate acetyl and cellulose acetate containing 0.1–10% of the proposed stabilizer before and after irradiating a PRK-2 mercury – quartz lamp for 2 hours.
Из таблицы видно, что предлагаемый ста билизатор значительно превосходит по зашитjHOMy действию к УФ-облучению известный i стабилизатортинувин.iIt can be seen from the table that the proposed stabilizer is significantly superior in protection to UV irradiation to the known i stabilizatorinuvin.i
Примера. В 15%-ном растворе ацетата целлюлозы в диметилформамиде раствор шэт «светостабилизатрр в количестве ОД-1О% от веса ацетата целлюлозы. Из полученного пр дильного раствора фор муют волокна, использу в качестве осайительной ванны раствор атиленл аккоп .Example. In a 15% solution of cellulose acetate in dimethylformamide, the solution was a “light stabilizer” in the amount of OD-1O% by weight of cellulose acetate. Fibers are formed from the obtained spinning solution, using the Atillen Ackop solution as a center bath.
