Abstract

PURPOSE: To keep high dust collective property inside as well as enhance dust separability by using a practically bonding contact-free entangled fine fiber unwoven fabric layer as a dust filtering face.
CONSTITUTION: The practically bonding contact-free entangled fine fiber unwoven fabric layer 1 is used as a dust filtering face in order to keep the high internal dust separablity better. And, the large fiber unwoven fabric layer 2 is used as a non-dust collecting face which serves to adhere partially between the aforesaid fine fiber unwoven fabric layer 1 and the large fiber unwoven fabic layer 3 with the aid of the bonding agent 2 to form a dust collection filter.
