Abstract:

In view of insufficient crimp elasticity and poor wearing comfort of polybutylene terephthalate/polyethylene terephthalate (PBT/PET) parallel composite fibers, tetrahydrofuran homopolyether (PTMG) was selected to modify PBT and conventional PET were used as raw materials to prepare PTMG-PBT/PET parallel composite fibers by composite spinning. The effect of PTMG mass fraction on the properties of polyether ester and composite fibers, and the crimp properties of composite fibers by heat treatment process were studied. The results show that with the increase of the mass fraction of PTMG, the water absorption and moisture absorption rate of polyether ester can reach 4.10% and 1.62% respectively, the contact angle can reach 63.81°, and the crimping performance of the composite fiber is also significantly improved, reaching a crimp ratio of 48%. Heat treatment can further improve the crimp properties of composite fibers and the effect of wet heat treatment is shown to be better than that of dry heat treatment. After wet heat treatment, the crimp ratio and crimp recovery of the composite fibers reach 70% and 55%, respectively. PTMG can also improve the normal pressure dye uptake rate of composite fibers, which reaches as high as 93.25%, and is 12% higher than that of PBT/PET parallel composite fibers.

Key words: tetrahydrofuran homopolyether, parallel composite fiber, moisture absorption property, heat treatment, crimp property, dye uptake rate
