摘要:

阐述了熔喷过程中纤维直径的细化机理,详细综述了熔喷工艺参数对超细纤维制备的影响效果,主要包括熔喷气流、温度、熔体挤出量和接收距离,总结了工艺方法对纤维直径衰减作用的一般规律及原理。最后介绍了模具类型对纤维直径的作用方式。进一步地,对传统模具进行创新设计或者在熔喷技术的基础上结合静电技术,是实现熔喷纤维向纳米尺度细化的有效途径。

Abstract:

This paper expounded the refinement mechanism of fiber diameter in the melt⁃blown process and discussed the influence of melt⁃blown process parameters on the preparation of ultrafine fibers, mainly including melt⁃blown air flow, temperature, melt extrusion capacity, and receiving distance. The general rules and principles of the effect of process methods on the attenuation of fiber diameter were summarized. Finally, the action modes of the mold type on the fiber diameter were introduced. Furthermore, the innovative design of traditional molds or their combination with the electrostatic technology based on the melt⁃blown technology will become an effective way to realize the refinement of melt⁃blown fibers to the nanoscale.

Key words: melt?blown technology, microfiber, polymer processing, electrostatic melt?blowing
