terephthalate (PET) were investigated with several techniques. The spinning conditions of
the copolyester fibers were discussed in detail. The results revealed that the glass transition
temperature and melt index of the copolyesters were increased with an increasing CHDM
content. The weight loss of the copolyesters was lower than that of regular PET (semi dull,
SD). The copolyester fibers had lower tenacity, modulus, and weight loss than SD. The …
