Abstract

The invention discloses a method for spinning poly-p-phenylenebenzobisthiazole (PBO) fibres. The method comprises the steps of pre-treatment, cotton opening and picking, cotton teasing, drawing, rough spinning and fine spinning. The method solves the difficult problem of spinning the poly-p-phenylenebenzobisthiazole fibres, and establishes a technical foundation of pure spinning of the PBO fibres, which is performed on cotton spinning equipment; yarns obtained via spinning have the advantages of glabrous surface, smoothness, less neps, uniform evenness and the like, can be widely applied to high-grade protective textiles and industrial textiles.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a spinning method of poly-p-phenylene benzobisoxazole fibers. Background technique [0002] Poly-p-phenylene benzobisoxazole fiber is the fiber with the highest strength, modulus and high temperature resistance among organic high-performance fibers. It has been widely used in special protection fields abroad. [0003] Due to its high modulus and high strength, poly(p-phenylenebenzobisoxazole) fiber has a typical sheath-core structure. During processing, the fiber is not easy to be cut, and the fiber is easily fibrillated by pulling and rubbing, and it is easy to produce A large number of neps, especially in the carding process, makes spinning difficult, with extremely uneven evenness and many neps. Japan Toyobo Co., Ltd. is currently the only manufacturer of poly-p-phenylene benzobisoxazole fibers. Judging from the purely spun yarn samples of poly-p-phenylene benzob...
