Description

лед ной уксусной кислотой пр:и МО-дуле 50 з течение 2-3 ч и темп е,.ре 20-25° С, затем удал ют избыток уксусной до содержани  100-150% от веса шелка, после чего .раствор ют шелк в 60-63%-ном водлом растворе |родан11стого  ат-ри  при 50° С. Колцентращи  полученного раствора дл-  формовали  14-15%.glacial acetic acid sp. and MO-dule 50 for 2-3 hours and temp, e, 20-25 ° C, then excess acetic acid to a content of 100-150% by weight of silk is removed, after which the silk is dissolved in 60-63% aqueous solution of | athena at 50 ° C. The centers of the resulting solution were molded 14-15%.

Предложенный спо-соб дает в озчможиость увеличить выход полимера .в 5-6 раз по оравнвн .ию 1C известным опособом, повыкпть стабильность пр дильнОГО раствора и его волокноо .бразующие свойства при моюром способе формованИ , а также качество сфоргмоваиного иокуаственного волокна.The proposed method makes it possible to increase the polymer yield by a factor of 5–6 by 1C using a known method, in order to ensure the stability of the spinning solution and its fiber-forming properties in the form of a mold, as well as the quality of the fiber formed.
