PTT [Poly(trimethylene terephthalate)] 織物의 物理的特性및 主觀的評價에 關한 硏究

Abstract

A new textile material, poly(trimethylene terephthalate) polymer, has been introduced to the textileindustry. The structure of PTT is similar to the PET, while the tensile deformation and subsequent recoveryproperty is better than that of PET. In this study, the physical and mechanical properties of textile wovenfabrics made of PTT, PET, and nylon 6 yarns as the filling yarn were determined using the KawabataEvaluation System (KES), including tensile, bending, shearing, compression, and surface related parameters.On top of these measurements, the subjective ratings by evaluators were performed on the fabric samples.From the examination of the stress-strain behavior of the yarn specimens focused on the recovery mode, itwas evident that the PTT specimen developed lower stress at 3% elongation. The subsequent recoverycurve showed that the PTT has less stress-decay rate than the other specimens, implying that the recoverybehavior of the PTT is recommendable for the end-uses including stretchable textile materials, sports wears,etc. The KES bending rigidity(B) value of the PTT sample fabric was lower than that of the PET samplefabric. Subjective evaluation of the fabric samples by the evaluators on the descriptive word pair soft - notsoft showed similar tendency with the KES B determination of the fabric samples.
