Abstract:

Aiming at problems of periodical excess capacity and constringent profit margin of large varieties of genera fibers, and in lrder 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 functionally 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 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 enhance in multifunctionality of general functional synthetic fibers in China, intelligent technological innovation level and international competition of synthetic fibers.
