纤维的结构控制技术正在从直径数十微米至十数微米级的超细纤维开始向应用复合纺丝技术的数微米级纤维以及最近应用特殊复合纺丝技术的纳米级纤维的截面结构设计发展。控制纳米级纤维结构有两方面的意义:一是为提高如力学强度和耐热性等宏观性能而提出纤维微结构的新概念和模型;二是纳米级结构可赋予纤维高性能或原功能的突破性提升。本文介绍帝人纤维公司开发的
Fiber structure control technology is starting from microfibers in the tens of micrometers to tens of micrometers in diameter, toward the cross-sectional structural design of several-micron fibers using composite spinning technology and nanofibers recently using special composite spinning technology. Controlling the structure of nanofibers has two meanings: one is to propose new concepts and models of the microstructure of the fibers for improving macroscopic properties such as mechanical strength and heat resistance; the other is that nanoscale structures can give high-performance or original functions Breakthrough upgrade. This article describes the Teijin Fiber Company developed
