Abstract

DSC curves of polyster/cotton blends indicate that the glass transition temperature,T g, of cotton varies with the blend composition. Standard curves for quality control purposes are presented and are based on either the cotton or PET transition peak areas. Factors that contribute to the size of the peak areas were determined: a composition coefficient factor and a thermal coefficient factor.

Résumé

Les courbes DSC des combinaisons polyester/coton indiquent que la température de transition vitreuseT g du coton varie avec la composition. On présente des courbes types pour le contrôle de la qualité d'après les surfaces des pics de transition du coton ou du PET. On a déterminé les facteurs qui influencent la dimension des surfaces des pics: l'un est en rapport avec la composition et l'autre avec le coefficient thermique.

Zusammenfassung

Die DSC-Kurven von Polyster/Baumwoll-Gemischen zeigen, dass die Glas-Übergangstemperatur (T g der Baumwolle sich mit der Zusammensetzung des Gemisches ändert. Standardkurven für Qualitätskontrollen werden gezeigt, welche auf den Übergangspeakflächen der Baumwolle oder des PETs beruhen. Die zur Grösse der Peakfläche beitragenden Faktoren wurden bestimmt: ein Zusammensetzungskoeffizient und ein thermischer Koeffizient.

Резюме

ДСК-кривые смесей пол иэфира и хлопка показ али, что температура пере хода Tg хлопка в стеклообраз ное состояние изменя ется с изменением состава с меси. Для качественно го контроля представле ны стандартные кривы е, которые определены на основе площади пиков хлопка или поли зфира. Установлены фа ктор состава и термически й фактор, определяющи е величину площади пик ов.
