据报道,我国已开发出具有自主知识产权的PTT(聚对苯二甲酸-丙二醇酯)纤维及改性PTT纤维关键装备及成套工艺技术,打通了生物基PTT纤维生产的技术链条,生物基PTT纤维有望实现规模化生产。PTT纤维被看做是未来聚酯纤维重要的替代产品,具有广泛的发展空间。它的重要原材料是PDO(1,3-丙二醇), It has been reported that China has developed PTT (poly (trimethylene terephthalate)) fiber and PTT fiber modified key equipment and complete set of technology with independent intellectual property rights, opened up the technical chain of bio-based PTT fiber production, bio-based PTT Fiber is expected to achieve large-scale production. PTT fiber is seen as an important alternative to polyester fiber in the future, with a wide range of development. Its important raw materials are PDO (1,3-propanediol),
