我国涤纶行业的差别化率在过去几年有了很大提高,已经达36%。国外现有的大部分差别化涤纶产品我国已经能够生产,目前已有27大类新产品转入批量生产,超细旦、高收缩、阳离子染料可染聚酯、多功能复合混纤复合长丝等发展迅猛。我国在超细纤维纺丝技术、各种截面纤维纺丝技术、微小粒子混合纺丝技术、聚合物改性技术、复合纤维技术等新合纤开发的关键技术攻关方面都取得了较大的突破。
The differentiation rate of China’s polyester industry has greatly increased in the past few years, reaching 36%. Most of the existing foreign differentiated polyester products in China have been able to produce, there are already 27 categories of new products into mass production, ultrafine denier, high shrinkage, cationic dyeable polyester, multi-functional composite fiber composite filament Rapid development. China has made great breakthroughs in key technologies such as ultra-fine fiber spinning technology, various cross-section fiber spinning technology, micro-particle hybrid spinning technology, polymer modification technology, and composite fiber technology .
