Abstract

Meltblown process is one of the major processes for nonwoven filters. In this study, the collection efficiency of meltblown nonwoven filters made of isotatic- polypropylene(i-PP) was examined for the various processing conditions such as die and air temperatures, die-to-collector distance(DCD) and attenuation air flow rate at the die. The collection efficiency for non-woven filter was found to increase with decreasing DCD, with increasing die temperature, or with increasing air flow rate. In addition, the quality factor of non-woven filter was excellent with increasing DCD in meltblown process like this.
