Abstract
Diverse new wool-like fabrics, where a touch with crispness and stiffness characteristic of wool fabrics are attempted, are being manufactured by the technology elements comprising false-twisting after air-jet entanglement of yarns having different characteristics, for example, different denier, different cross-sectional shapes, and/or different thermal shrinkage properties. Polyester filament yarn fabrics, prepared on an experimental scale based on a similar technology, were compared with wool containing fabrics. Subjected evaluation of the fabrics were carried out based on the questionnaire with twenty-one descriptive word paris including 'smooth-not smooth', 'light-heavy', 'lustrous-not lustrous', and so on. For the luster characterization, a glossmeter was employed as a preliminary step. Statistical analyses including factor analysis of the subjective evaluation results by the evaluators were carried out. Factor analysis of the results has revealed that the twenty descriptors could be grouped into five. The factor 1 comprises 'smooth, rough, and soft', the factor 2 'wrinkle-prone, clinging, dangling, and lustrous', and the factor 3 'springy, extensible, and stretchable'. The factor 4 comprises 'hard, stiff, and strong', and the factor 5 'light, warm. compressible'.
