Effect of mechanical properties of fabrics on change of bloused line during cyclic wear

This study focuses on the objective evaluation of the silhouette of the front bloused line of women’s blouses, in which fusible interlinings are used in the construction of the open part. The wearing test was carried out over three seasons and the bloused lines before and after the fatigue were observed and examined in relation to the mechanical properties of fused composites and their constituent fabrics. Since bending properties and KOSHI were found to play an important role in the change of the silhouette formation of bloused lines, those of fused fabrics were studied by applying the simple model. Finally, in the sensory test, applying the blouses fatigued and not fatigued, their open parts made up of fused composite are evaluated by 71 consumers for their preference. The essential concepts involved in the consumer preference were clarified.

Application of Size Distribution Analysis to Wrinkle Evaluation of Textile Materials

An evaluation method of wrinkle shapes on fabrics using simple morphological operations is proposed. It calculates the size density function of the object indicating the region surrounded by a folded fabric in the experimental condition of the standard wrinkle/crease angle test. The characteristics of the size density function and the parameters of the linear and cubic function fitted to the size density function indicate the fabric shape characteristics, which correspond to visual edge sharpness and roundedness of pleat lines, as well as their mechanical properties.
