Claims (1)
- Элементарные волокна на основе растворимого в ацетоне ацетата целлюлозы, причем степень полимеризации (СП) ацетата целлюлозы лежит между 110 и 210 и степень замещения (СЗ) предпочтительно между 2,2 и 2,7. Это позволяет получить оптически изотропные прядильные растворы, концентрация которых по ацетату целлюлозы составляет примерно от 35 до 47 мас.%. Выпрядение из такого оптически изотропного прядильного раствора, особенно способом сухого прядения, в таком случае обеспечивает получение элементарных волокон, т.к. связанные с рекуперацией ацетона расходы могут быть значительно уменьшены без ухудшения свойств элементарных волокон, которые особенно пригодны для получения материала фильтров сигарет.
