Resumen de la tesis doctoral Influencia e interacción de las variables de termofijado en la estructura fina del poli(etilentereftalato).

Fernando Bernal Sánchez


The main object of this thesis was the study of structural variations in polyester fibres when heat set, through the determination of its fine structural parameters. The materials employed were fabric samples in grey state and scoured which were further on heat set in an industrial stenter under twelve different industrial conditions of temperature, time and overfeed. Three types of techniques were employed: Exclusion Chromatography, Density Gradient Column, Differential Scanning Calorimetry, Critical Dissolution Time, Contraction Force, Thermomechanical Analysis and Iodine Sorption.
