A series of tests established the heat resistance of nonwoven fabrics manufactured from bicomponent polypropylene/polyethylene terephthalate (PP/PET) and polypropylene/polybutylene terephthalate (PP/PBT) microfibers on a 24-inch Reicofil bicomponent melt blown line with a side-by-side configuration that imparted higher crimp, lower average fiber diameter, higher web quality, and better bonding properties. PET melt blown nonwoven webs shrank to 23 percent after exposure to 120 degrees centigrade for 3 minutes. All bicomponent samples exhibited excellent dimensional stability when exposed to heat at 90-155 degrees centigrade for 3 minutes. The introduction of small amounts of PP stabilized the heat shrinkage of PP/PET melt blown webs. Both 100 percent PBT and PP/PBT webs exhibited excellent thermal dimensional stability. Abstract.
