生物基聚酯与聚酰胺纤维的研发进展

为促进我国化纤行业转型升级与持续发展,对以生物基聚对苯二甲酸乙二醇酯纤维、聚对苯二甲酸-1,3-丙二醇酯纤维、聚乳酸纤维、聚呋喃二甲酸乙二醇酯纤维、聚呋喃二甲酸丙二醇酯纤维,以及生物基聚酰胺56纤维为代表的生物基聚酯、聚酰胺纤维的国内外生产现状,市场需求、技术发展及趋势进行了综述,对全球生物基纤维专利的分布、各主要开发机构的专利战略及技术情况进行了梳理及剖析。在此基础上结合国内高分子材料产业实际,对我国生物基聚酯、聚酰胺纤维的发展建言应重点攻关生物基乙二醇、对苯二甲酸、己二胺等战略性生物基单体制备的核心技术,同时就重点任务和发展路径提出了建议。

Research and development progress of bio-based polyester and polyamide fibers

To promote the transformation,upgrading and sustainable development of China′s chemical fiber industry,this paper reviewed the global market,technology development and trend of bio-based polyester and polyamide fibers with bio-based polyethylene terephthalate,polytrimethylene terephthalate,polylactic acid,poly(ethylene furandicarboxylate),poly(propylene furandicaboxylate),polyamide 56 fibers as representatives,summarized and analyzed the global patent distribution of bio-based fibers,the patent strategy and technology of the major organizations in the world.Based on this and the actual situation of domestic industry of polymer materials,the key item was suggested to break through the core technology in preparation of strategic bio-based monomers such as ethylene glycol,terephthalic acid and 1,6-hexanediamine.At the same time,some advices were put forward on the major tasks and development path for research and development of bio-based polyester and polyamide fibers in China.
