摘要： The present invention provides a method for manufacturing para-aramid fibers, which includes: spinning a polymeric solution containing aramid polymer in an organic solvent through a spinneret into an inert gas to partially remove the organic solvent contained in the spun fiber; contacting the spun fiber with conditioning solution, so as to maintain residual water in fiber in a range of 10 to 15%; and subjecting the treated fiber to drawing, washing and heating in a dry-spinning manner. The present invention may greatly reduce energy consumption and costs for recovery of the solvent, as compared to a conventional manufacturing method of aramid fiber in a wet-spinning manner. Further, the present invention may solve conventional problems such as corrosion of apparatus, deterioration of working environments, or the like, since a concentrated sulfuric acid solvent is not used in a spinning process. Still further, the present invention may conduct drawing and heating after maintaining the residual water in fiber in a range of 10 to 15% before drawing, thereby remarkably improving the strength and elastic modulus of the fiber.
摘要翻译：本发明提供对位芳族聚酰胺纤维的制造方法，其包括：将含有芳族聚酰胺聚合物的有机溶剂中的聚合物溶液通过喷丝头纺丝成惰性气体，以部分除去纺丝纤维中所含的有机溶剂; 使纺丝纤维与调理溶液接触，以保持纤维中的残留水在10〜15％的范围内。对经处理的纤维进行拉伸，洗涤和干纺加热。与传统的芳族聚酰胺纤维的湿法纺丝方法相比，本发明可以大大降低能量消耗和回收溶剂的成本。此外，由于在纺丝工序中不使用浓硫酸溶剂，本发明可以解决设备腐蚀，工作环境劣化等常规问题。此外，本发明可以在拉伸前将纤维中的残留水保持在10〜15％的范围内进行拉伸加热，从而显着提高纤维的强度和弹性模量。

摘要： Described is a method for dissolving PPTA or copolymers thereof in sulfuric acid using a twin screw extruder having transporting, mixing, and kneading elements with an entering zone, an intermediate zone, a mixing zone, a negative transport zone, a degassing zone, and a pressure build-up zone. The method includes transporting PPTA or copolymer thereof into the entering zone at a transport capacity low enough as to prevent sulfuric acid entering the entering zone; introducing sulfuric acid in the entering or intermediate zone; essentially fully filling the mixing zone to allow sufficient time to mix and dissolve PPTA or copolymer thereof in the sulfuric acid to obtain a PPTA or copolymer-sulfuric acid solution; creating after the mixing zone a negative transport zone to obtain a product lock between the mixing zone and the degassing zone; creating a thin film of the PPTA or copolymer-sulfuric acid solution in the degassing zone to degas the solution; and entering the solution into the output pressure build-up zone to partially fill this zone and to leave the twin screw extruder.
