通用合成纤维功能化基础问题与发展趋势

Basic issues and development trends on general synthetic fibers with high functionalization

针对国内大品种通用纤维面临的阶段性产能过剩和利润压缩问题,同时为克服产品同质化竞争严重,新型功能纤维稳定性不足,产品技术创新能力弱等缺点,急需实现功能性合成纤维产品的创新与技术支撑,提高产品附加值。首先从聚合物可控原位合成、合成纤维加工成型与调控以及纤维表面修饰与功能化3个主要方面阐述了通用合成纤维功能化过程中存在的基本科学问题;其次介绍了国际市场中功能纤维由被动适应向主动创新设计的发展趋势,为全面提升我国通用合成纤维的多功能化、智能化的科技创新水平和提高合成纤维产品的国际竞争力提供了思路与理论支持。

Aiming at problems of periodical excess capacity and constringent profit margin of large varieties of general fibers, and in order to overcome shortcomings such as serious competition of homogeneous products in China,insufficient stability of newly functional fibers and weak innovation in product technology,innovative and technical supports for functional synthetic fibers are urgent to be realized to add more value in products. Basic scientific problems of general functional fibers during functionalization were firstly expressed in three main aspects of controllable in situ synthesis of polymers,machine shaping and regulating of synthetic fibers and modification and functionalization on the surface of fibers. Then the development trends of functional fibers in international market from passive adaptation to active innovation design was introduced,providing a direction and theoretical support for comprehensive enhancement in multifunctionality of general functional synthetic fibers in China,intelligent technological innovation level and international competition of synthetic fibers.
