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
