Изобретение относится к области производства химических волокон, а также к отраслям промышленности, где требуется тщательная очистка расплавов полимеров от гетерогенных включений, а именно к процессу фильтрации высоковязких расплавов полимеров. Для повышения стабильности технологического процесса и увеличения срока службы фильерных комплектов в качестве фильтрующего материала для высоковязких расплавов полимеров предлагается применить нетканый материал из углеродных волокон, имеющий диаметр элементарных волокон 8 oC 12 мкм, с поверхностной плотностью 0,1 oC 0,5 кг.м- 2, толщиной слоя 5 oC 7 мм, воздухопроницаемостью 200 oC 250 дм3 (м3.с)- 1.The invention relates to the production of chemical fibers, as well as to industries that require thorough cleaning of polymer melts from heterogeneous inclusions, namely, the process of filtering highly viscous polymer melts. To increase the stability of the technological process and increase the service life of the die sets, it is proposed to use carbon fiber nonwoven material having a diameter of 8 o C 12 microns with a surface density of 0.1 o C 0.5 kg as a filtering material for highly viscous polymer melts. m - 2 , layer thickness 5 o C 7 mm, air permeability 200 o C 250 dm 3 (m 3. s ) - 1 .
