多重焦點畵像技法을 適用한 綿纖維光澤分析및 綿織物의 光澤에 關한 硏究

Abstract

Surface properties, including the texture and the luster, of cotton fibers and yarns thereof play animportant role in textile technology. The convolutions and the cross-sectional shape of the cotton fiberaffect the fabric texture and the luster accordingly. Mercerization of the cotton fabric affects the luster,strength, and other properties of the fabric. In this study, the effect of mercerization was examined on theluster of the cotton fabric, together with the effect of polishing treatment. One of the traditional methodsdetermining the fabric luster is the use of glossmeter or goniometric glossmeter. The use of glossmetergives successful results in determining the gloss of rather flat and continuous surface such as plasticsheet, painted surface, or paper products. Since the textile fabrics have diverse surface structures andtextures, these could be regarded as having three-dimensional surface. Such complexity imposes somedifficulties for differentiating subtle surface luster properties of diverse textile fabrics. The advancement inthe area of imaging technologies has enabled the micro-scale analysis of the surface textures and thefabric luster recently. Using a CCD camera, the surface luster images were taken at various incidentillumination conditions. Microscale analysis, including the blob analysis, of the images coulddifferentiate the subtle luster properties present in a group of cotton fabric samples comprisingmercerized cotton fabric, non-mercerized cotton fabric, polished cotton fabric, and a standard cottonfabric. The glossmeter measurement gave satisfactory but limited differentiation among the samples,whose luster differences are easily recognizable with visual observation, except for the mercerizedcotton fabric sample and the non-mercerized cotton fabric. The microscale analysis of the fabric lustercould, therefore, help understand the nature of diverse textile fabric luster.
