Abstract

A spunbonded material having improved tensile strength is made by (1) continuously extruding a propylene homopolymer or random propylene/ethylene copolymer having a melt flow rate of about 3 to about 30 g/10 min at a temperature above 500°F through a spinneret to form discrete filaments, (2) drawing the filaments to molecularly orient the polymer filaments, and (3) depositing the filaments in a substantially random manner onto a carrier belt to form a web. The propylene polymer contains an additives package that includes an organic phosphite, a hindered phenol compound, calcium stearate, and, optionally, a hydrotalcite compound.
