1纺织用聚酯的内部回收——驱动力目前,主要的现代化纺织用聚酯生产厂中,高产能生产线直接纺长丝或短纤维的日产量大约在400~800 t。尤其在中国,在单个生产地点,公司拥有多条这样的生产线。随着现代化纺丝设备的高度自动化及聚合工
1 Internal recycling of textile polyester - the driving force At present, the major modern textile polyester production plant, high-capacity production line direct spinning of short fibers or filament yarn in about 400 ~ 800 t. Especially in China, the company has several such production lines at a single production location. With the high degree of automation and polymerization of modern spinning equipment
