TECHOLOGY (1) YARN PACKAGES ARE HEATED 3-5 HOURS IN SLEACHING OVENS. (2) YARNS ARE HEATED ON-LINE WITH HOT ROLLS OR WITH RADIANT HEATING. RESULTS BOTH HEAT TREATHENTS REMOVED ALL DETECTABLE FC-143 ROH YARN. OVEN HEATING (190C) REQUIRED < 30 MINUTES WITH YARN, BUT 3-5 HOURS WITH PACKAGES (2-1/2 HOURS REQUIRED FOR CORE TO REACH OVEN TEMPERATURE). ON-LINE HEATING FASTER, AS EXPECTED: 99% REMOVAL IN 6 SECONDS ON 276C HOT ROLLS. ~ 94% REMOVAL IN 4 SECONDS USING 500C RADIANT OVEN. PROBLENS WITH OVEN HEATED YARNS: - STIFFNESS CAUSED BY OVERORYING WHICH HARDENS DISPERSION COATING. - DISCOLORATION VIA OXIDATICH OF TRITOND. ~ PACKING FAILED INTERNAL TEST.
