Reaction Steps

This material is then spun to a 14-filament yarn at a block temperature of 249°C. at a windup speed of 119 yards (108.8 meters) per minute. The yarn has a relative viscosity of 14.4 and contains 0.057% nitrogen and 6 mole % adipate units. The yarn is drawn 5.6X with a feed roll temperature of 68°C. and a draw roll temperature of 90°C. After relaxing at 180°C. for 5 minutes, the yarn has a tenacity of 2.5 grams per denier and an elongation of 51%. The relaxed yarn dyes to a medium shade when dyed 90 minutes at 100°C. at pH 4.5 with 3% owy Acid Blue 40 (C.I. 62125), using a bath-to-yarn weight ratio of about 100.1.
