1绪言纳米纤维作为超细纤维近年来引起了人们的关注。回顾纤维的发展历史,纤维的第二次产业革命是合成纤维的发现。世界上最早的合成纤维是1938年开发的聚酰胺纤维,其后开始了开发功能性合成纤维的竞争。合成纤维的开发是以天然纤维为样本,人为地创造丝和棉等的纤维风格,可以说 1 Introduction Nanofibers as microfibers have drawn people’s attention in recent years. Reviewing the history of fiber development, the second industrial revolution of fiber is the discovery of synthetic fibers. The first synthetic fiber in the world was the polyamide fiber developed in 1938, after which competition for the development of functional synthetic fibers began. The development of synthetic fibers is a natural fiber samples, artificially create silk and cotton fiber style, it can be said
