Abstract:Polietilentereftalatna (PET) vlakna so med procesom njihovega oblikovanja in preoblikovanja, med barvanjem, plemenitenjem in med drugimi procesi izpostavljena visokim temperaturam. Toplotna obdelava pri temperaturah nad temperaturo steklastega prehoda vpliva na kristaliničnost, dimenzije kristalitov, strukturno periodičnost, kristalino in amorfno orientacijo, itd. Strukturne spremembe PET vlaken, ki jih povzroči toplotna obdelava v vodnem mediju ali vročem zraku, smo proučili z ramansko spektroskopijo, ki postaja zelo pomembna tehnika za karakterizacijo kemijskih in fizikalnih lastnosti polimerov v tekstilni kemiji. Osredotočili smo se na določitev strukturnih sprememb, ki izvirajo iz konformacijskih prehodov etilenglikolnega dela PET. Rezultati kažejo, da toplotna obdelava povzroči spremembe v trans/gauche konformacijskem razmerju. Ugotovili smo, da ima temperatura močnejši vpliv kot uporabljeni medij.

Title:Raman spectroscopic studies of structural changes in polyethylene terephthalate fibres
Abstract:Poly(ethylenterephthalate) PET fibres are exposed to high temperatures during the fibre formation process, dyeing, finishing and other processes. The thermal treatment of PET fibres above the glass transition temperature changes the crystallinity, crystals' dimensions, structure periodicity, crystal and amorphous orientation, etc. We have studied the structural changes of PET fibres depending on different treatment media (water, air) using Raman spectroscopy. Raman spectroscopy is becoming one of the most significant techniques for characterization of the chemical and physical properties of polymers in textile chemistry. We focused on structural changes due to conformational transitions of ethylene glycol in PET fibres. The results show that thermal treatment causes an increase of trans/gauche conformational ratio with annealing temperature. The presented results show that the annealing temperature has greater influence on structural changes in PET samples than the used treatment medium.
