| Abstract: | The properties of PET\|PBT copolyester fiber were studied. The results showed that PET\|PBT fiber subjected to 1 time or 10 times stretch had better stretch elastic recovery than PET fiber. One\|time\|stretch at 5% yielded stretch recovery of 100%, almost the same as that of PBT. Moreover, PET\|PBT fiber exhibits 180° flexural resilience higher than that of PET or PBT fiber and matching with that of PA6 fiber, and shows dyeing behavior far better than that of PET fiber. The dyeing behavior increases with PBT content. The dye uptake of copolyester fiber is up to 91.5% when PBT content is 25%. |
