Abstract:

Aiming at the problems of low fiber splitting rate and poor drapability of hollow pie-segmented microfiber nonwoven, high shrinkage polyester/polyamide 6 microfiber nonwovens with different areal densities were prepared by bicomponent spunbond spunlace technology with high shrinkage polyester (HSPET) and polyamide (PA6) as raw materials. The effect of heat shrinkage treatment on fiber splitting rate, drapability, softness, air permeability, filtration efficiency and mechanical properties of the nonwovens were analyzed. The results show that when the spunlace pressure was constant, the fiber splitting rate of the HSPET/PA6 nonwoven fabric is increased by 48.1% compared with that of PET/PA6 nonwoven. After heat shrinkage treatment, the shrinkage rate of HSPET/PA6 nonwoven reaches 20.31%. Heat shrinkage promotes the fiber splitting, resulting in a relatively fluffy internal structure of the nonwoven, offering drapability improvement. The filtration efficiency of HSPET/PA6 nonwovens was increased as the increased fiber splitting rate. The filtration efficiency of HSPET/PA6 nonwovens was close to 100% for particles with size greater than or equal to 1.5 μm when the areal density of the nonwoven was 140 g/m2, but the filtration efficiency of HSPET/PA6 nonwovens was reduced after heat shrinkage treatment.
