Abstract:
A PROCESS FOR INCREASING THE WHITENESS OF A FILAMENT EXTRUDED FROM A POLYMER BLEND COMPRISED OF POLYESTER AND POLYAMIDE WHICH COMPRISES INCORPORATING IN THE POLYMER BLEND, PRIOR TO EXTRUSION THEREOF, ABOUT 0.1 TO 5 WEIGHT PERCENT, BASED UPON THE WEIGHT OF THE POLYAMIDE AND POLYESTER, OF A STERICALLY HINDERED PHENOLIC COMPOUND AND MELT EXTRUDING THE POLYMER BLEND TO FORM A FILAMENT HAVING INCREASED WHITENESS.
