| description | FIELD: production of synthetic fibers. SUBSTANCE: invention relates to drawing threads and braids after formation from polyester melt in order to obtain filaments, fibers, and monothreads applicable in chemical industry. To achieve this, formed amorphous undirected polyester thread (braid) is subjected to undirected drawing in several steps, for example, in 2-6 steps. In every step, undirected drawing factor is within the range from 1.5 to undirected drawing factor in the first step. EFFECT: improved procedure.
Использование: получение химических волокон, а именно вытягивание нитей и жгутов после формования из расплава полиэфира с целью получения комплексных нитей, волокон, мононитей в химической промышленности. Сущность изобретения: сформованную аморфную неориентированную полиэфирную нить(жгут)подвергают неориентационному вытягиванию в несколько стадий, например в 2 - 6, при этом на каждой стадии кратность неориентационного вытягивания находится в пределах: λ= 1,5...λ, где λи λкратность неориентационного вытягивания, соответственно на 1 и последующих стадиях. |
