Abstract

Описан способ получения подвергнутых вытяжке комплексных полиэфирных нитей, пригодных для использования в технических целях как шины, корд, конвейерные ленты и т.п. При этом крошка полимера или гранулят так называемой «текстильной степени» сначала подвергают дополнительной конденсации в специальном реакторе до собственной вязкости >0,9 дл/г и концентрации концевых карбоксильных групп менее 15 ммоль/кг. Нити прядут в прядильной установке, имеющей три зоны, а именно зону термостатирования, зону охлаждения и зону кондиционирования. Нити прядут со скоростью прядения от 2500 до 3400, затем подвергают двукратной вытяжке и наматывают со скоростью намотки по крайней мере 5500 м.Международная заявка была опубликована вместе с отчетом о международном поиске.Describes a method for producing stretched polyester yarns suitable for technical use such as tires, cords, conveyor belts, and the like. At the same time, a polymer crumb or a so-called “textile degree” granulate is first subjected to additional condensation in a special reactor to an intrinsic viscosity of> 0.9 dL / g and a concentration of terminal carboxyl groups of less than 15 mmol / kg. The threads are spun in a spinning machine having three zones, namely a temperature control zone, a cooling zone and an air conditioning zone. The threads are spun with a spinning speed from 2500 to 3400, then subjected to a double stretch and wound with a winding speed of at least 5500 m. The international application was published along with an international search report.
