针刺加工对橘瓣双组分纺粘水刺布过滤性能的影响
Effect of needle processing on filtration performance of segmented pie bicomponent spunbond-spunlace nonwovens
摘要
Abstract
In order to make more segmented pie fibrils cleaved into superfine fibers, thereby improving the filtration performance of segmented pie bicomponent spunbond-spunlace nonwovens, multi-layer low-weight (40 g/m2) PET-PA6 segmented pie bicomponent spunbond-spunlace nonwovens were processed by needle-punching, and four kinds of different weight segmented pie bicomponent spunbond-spunlace nonwovens with needle-punched were prepared. The filtration efficiency and resistance of segmented pie bicomponent spunbond-spunlace nonwovens before and after acupuncture were tested. Filtration performances of acupuncture nonwovens and laminated spunbond-spunlace nonwovens with the 40 g/m2, segmented pie bicomponent spunbond-spunlace nonwovens in different gram weight were compared. The results showed that the splitting rate of segmented pie fibril was high after acupuncture, the filtration efficiency of the nonwovens was improved, and the resistance of the filter decreased significantly; the filtration resistance of superfine fiber nonwovens with acupuncture decreased by about 2/3 compared with spunbond-spunlace nonwovens with 160 g/m2. It illustrates needle processing is a method to improve filtration performance of segmented pie bicomponent spunbond-spunlace nonwovens.关键词
