【摘要】 以聚丙烯切片为原料,制备熔喷超细纤维非织造布保暖材料,采用电子扫描显微镜分析了该熔喷非织造保暖材料的纤网形态结构,并对其在不同熔喷加工工艺参数下的蓬松度、透气性能和保暖性能进行了测试。结果表明,熔喷超细纤维及三维网状结构使得其具有极好的保暖性;空压机转速和接收距离的增加提高了纤网的孔隙率和蓬松度,从而使熔喷保暖絮片的保暖性增加。更多还原

【Abstract】 Superfine fiber nonwoven heat insulation waddings were prepared by meltblown technology with polypropylene in this paper.The web microstructure of melt-blown nonwovens was analyzed using SEM,and the properties of air permeability,compressive and heat insulation under different melt-blown process were dicussed. The conclusion shows that meltblown microfiber and three-dimensional network structure make it have excellent heat retention;the increase of the air compressor speed and DCD can promote porosity and bulkiness, so that the heat insulation properties are improved.更多还原
