由于高科技纤维是支撑高科技产业发展的重要新材料,关系到传统产业特别是支柱产业的更新换代和产业升级以及国防建设,因此日本早在20世纪80年代初就把投资重点由传统化纤转向高科技纤维。 经过20多年的发展,日本的高科技纤维产业已经在总体上居世界领先地位,特别是功能纤维和高强模纤维;日本的PAN基碳纤维总产能已经占世界总产能的3/4,产量占70％,聚芳酯纤维、PBO纤维、酚醛纤维、聚乳酸纤维等,最早都起源与美国,但是最终产业化都在日本,超强PVA纤维也是日本独有的。有些日本没有的或属弱势的重要品种,日本化纤公司采取合资发展或者收购的方式来拥有,例如80年代三菱人造丝收购
As high-tech fibers are an important new material supporting the development of high-tech industries and related to the upgrading and upgrading of traditional industries, especially pillar industries, and national defense construction, Japan shifted its investment focus from traditional chemical fiber back to the early 1980s High-tech fiber. After more than 20 years of development, the high-tech fiber industry in Japan has been leading the world in terms of overall performance, especially for functional fibers and high-strength module fibers. Japan’s total production capacity of PAN-based carbon fibers has accounted for three-quarters of the world’s total production capacity and its output accounts for 70% %, Polyarylate fiber, PBO fiber, phenolic fiber, polylactic acid fiber, etc., originated in the United States with the earliest, but the final industrialization is in Japan. Super PVA fiber is also unique in Japan. Some important or not important varieties in Japan, Japan’s chemical fiber companies to take joint development or acquisition to own the way, such as the 80’s Mitsubishi Rayon acquisition
