聚乙烯超细纤维非织造工艺研究进展
Research progress in nonwoven technology of polyethylene ultrafine fibers
摘要
Abstract
To understand the development status of polyethylene(PE)ultrafine fibers as a chemical product,the nonwoven technology of ultrafine fibers at home and abroad was introduced and analyzed from the aspect of fiber fineness,and the spin-ning mechanisms,refining methods,and existing problems of wet spinning,flash phase separation,electrospinning,and melt blowing methods were reviewed.The key factors of wet spinning were high-quality gel solution and super drawing.The morphology of the prepared fibers was directly influenced by the degree of entanglement of polymer molecular chains,phase changes,and degree of synergistic curing and stretching of multiphase flow in flash evaporation phase separation.Due to the non-polar nature,high molecular weight,and high viscosity,PE is mostly electrospun through using solvents and con-ductive particles in solutions.However,greener melt electrospinning has attracted attention,because it can refine the fibers through blending small molecular substances,improving degradation temperature,lowering viscosity,and setting environ-mental temperature to extend whip time.The effect of process parameter on the separation of multi-component fibers after blending and melt spraying was analyzed.Finally,the hot research directions in future were pointed out,including the sus-tainable development technologies for supercritical green fluids and halogen-free environmentally friendly solvents.关键词
