Chemical, Structural and Thermal Changes in PET Caused by Solvent Induced Polymer Crystallisation

Abstract: The structural and thermal properties of solvent-induced poly(ethylene terephthalate) (PET) polyester have been investigated. Flat, high twist and spun yarns were treated with trichloroacetic acid-methylene chloride (TCAMC) mixed solvent for 5 min at about 25 °C. The treatment influenced the solvent- induced crystallisation in PET, and the high interacting power of TCAMC with PET was substantiated. An increase in X-ray crystallinity was observed in the treated flat yarn but the orientation was reduced. The var… Show more

“…The current study was conducted on 100% Polyester fabric. It is likely that the action of solvent on fabric would be different from that of flat polyester yarn published earlier [24]. There has been no noteworthy difference between control and TCAMC treated cotton, cotton/bamboo, cotton/polyester and polyester fabrics in terms of abrasion.…”

“…It can be observed from Table 4 that the abrasive wear resistance of polyester decreased as the treatment time and the concentration increased. It has been shown in previous study that, at extreme treatment condition (5% TCAMC), the abrasive wear resistance of flat polyester yarn increased four times than that of the control [24]. It is well known that PET fibres are partially crystalline in nature and are comprised of repeated ethylene segment units as well as aromatic rings, which influence the intrinsic stiffness of the chain [25].…”

“…The effect of azeotropic mixture of solvent pretreatments on the dyeing behavior of 80 : 20 PCF was studied by dyeing the pretreated and untreated fabrics for different dyeing time intervals (30,45, and 60 minutes) and at different temperatures (80, 95, and 110…”

“…In the case of intercrystalline interaction, the solvent penetrates inside the amorphous region only. The polymer chains within this region are under lower stress, and this generally results in the rearrangement of molecular chains [29,30]. In this case, crystallization takes place in the swollen state and crystalline areas of the sample increase.…”
