Description
замачивани и сушки извиток полностью восстанавливаетс .soaking and drying the curl is completely restored.
Пример 2. Вискозу, содержащую 7,4% а-целлюлозы и 6,4% гидроокиси натри и имеющую зрелость 6,0 по хлориду натри и в зкость 9,0 с, формуют в осадительную ванну, содержащую 60 г/л серной кислоты, 240 г/л сульфата натри и 70 г/л сульфата алюмини нри 38°С. Скорость формовани 40 м/мйн. Свежесформованное волокно выт гивают на 15% на воздухе нри 28°С и на 50% в нластификационной ванне нри 95°С. Готовое волокно имеет нрочность 25 гс/текс, удлинение 22% и 3,5 извитка на 1 см. После п тикратного замачивани и сушки извиток полностью восстанавливаетс .Example 2. Viscose, containing 7.4% a-cellulose and 6.4% sodium hydroxide and having a maturity of 6.0 sodium chloride and a viscosity of 9.0 s, is formed into a precipitation bath containing 60 g / l of sulfuric acid, 240 g / l sodium sulfate and 70 g / l aluminum sulfate at 38 ° C. Forming speed 40 m / min. The freshly formed fiber is drawn by 15% in air at 28 ° C and by 50% in a plasticizer at 95 ° C. The finished fiber has a normality of 25 gf / tex, an elongation of 22% and 3.5 curl per cm. After five soaking and drying, the curl is fully restored.
Пример 3. Вискозу, содержащую 7,2% а-целлюлозы и 6,4% гидроокиси натри и имеющую зрелость 6,5 но хлориду натри и в зкость 110 с, формуют в осадительную ванну, содержащую 40 г/л серной кислоты , 50 г/л сульфата натри и 100 г/л сульфата алюмини при температуре 35°С. Скорость формовани 40 м/мин. Свежесформованное волокно выт гивают на 10% на воздухе при 25°С и на 40% в пластификационной ванне при 94°С. Готовое волокно имеет прочность 26,5 гс/текс, удлинение 23% и 2,5 извитка на 1 см. После п тикратного замачивани и сушки извиток полностью восстанавливаетс .Example 3. Viscose containing 7.2% a-cellulose and 6.4% sodium hydroxide and having a maturity of 6.5 but sodium chloride and a viscosity of 110 s is molded into a precipitation bath containing 40 g / l of sulfuric acid, 50 g / l of sodium sulfate and 100 g / l of aluminum sulfate at a temperature of 35 ° C. Forming speed 40 m / min. The freshly formed fiber is drawn at 10% in air at 25 ° C and at 40% in a plasticizing bath at 94 ° C. The finished fiber has a strength of 26.5 gf / tex, an elongation of 23% and 2.5 twists per cm. After five times soaking and drying, the twists are fully restored.
Предлагаемый способ позвол ет получить структурно-извитое волокно с 2,5-4 извитками на 1 см. Причем после многократного (4-5 раз) замачивани в воде иThe proposed method allows to obtain a structurally crimped fiber with 2.5-4 curls per 1 cm. And after repeated (4-5 times) soaking in water and
последующей сушки извиток восстанавливаетс в первоначальном виде.the subsequent drying of the curls is restored in its original form.
Получение устойчивого к мокрым обработкам извитка улучшает потребительские свойства тканей и облегчает текстильную переработку волокна.Getting a wet-resistant curl improves consumer properties of fabrics and facilitates textile fiber processing.
