Description
Известен способ модификации ацетата целлюлозы путем введени в пр дильный раствор бифункциональных Л-метилольных гетероциклических азотистых соединений и последующей термообработки волокон.A known method for modifying cellulose acetate is by introducing into the spinning solution bifunctional L-methylol heterocyclic nitrogen compounds and subsequent heat treatment of the fibers.
Дл улучшени физико-механических свойств ацетатных волокон водорастворимый модификатор ввод т в пр дильный раствор, содержащий 3-6% воды. В качестве водорастворимого модификатора используют диметилолэтиленмочевину или диметлолоксиэтилтриазон .To improve the physicomechanical properties of acetate fibers, a water-soluble modifier is introduced into a spinning solution containing 3-6% water. Dimethyl ethylene urea or dimethyl looxy ethyl triazone is used as a water soluble modifier.
Пример I. Водный раствор диметилолэтиленмочевины с катализатором MgCb добавл ют в пр дильный раствор вторичной ацетилцеллюлозы в смеси вода: ацетон (95:5), так что количество модификатора составл ет 5-8% от веса ацетата. Из полученного раствора формуют волокно по сухому способу и подвергают термообработке при 180°С 15 мин. Полученные модифицированные волокна обладают повышенной устойчивостью к двойным изгибам, термостойкостью и светостойкостью .Example I. An aqueous solution of dimethylol ethylene urea with MgCb catalyst is added to a spinning solution of secondary cellulose acetate in water: acetone (95: 5) so that the amount of modifier is 5-8% by weight of acetate. From the resulting solution, the fiber is molded by the dry method and heat treated at 180 ° C for 15 minutes. The obtained modified fibers have an increased resistance to double bending, heat resistance and light resistance.
Пример 2. Модифицированные волокна получают в услови х, описанных в примере 1, но в качестве модификатора используют диметилолоксиэтилтриазон . Example 2. Modified fibers are prepared under the conditions described in Example 1, but using dimethyloloxyethyl triazone as a modifier.
