ABSTRACT:
The present invention provides conjugate fibers having an ethylene polymer component and a propylene polymer component, which are highly crimpable even at fine deniers. Also provided are nonwoven fabrics made from the fibers. The propylene polymer component of the conjugate fiber contains a propylene polymer having a melt flow rate between about 50 g/10 min. and 200 g/10 min. as measured in accordance with ASTM D1238, Testing Condition 230/2.16.
