The Preparation of Spunbonded PA6/PET Segment Bicomponent Fiber

摘要

According to the property study of the polyamide 6 and polyester chips, the process parameters have been confirmed to prepare the spunbonded PA6/PET segmentation bicomponent fiber. Through the cross section study, it was found that the cross section structure was deeply affected by the spinning pressure and temperature of the melt mass. Meanwhile the drawing parameters had important influence on the fineness and strength of the fiber.
