초록

This study investigated mechanical properties, drape coefficients and node indices of stretch fabrics. We applied mechanical properties to exhibited tailorability control in HESC and evaluated making-up. The mechanical properties such as tensile, bending, shearing, compression, surface characteristic values, thickness and weight were measured by the KES-F system and drape coefficient by drape tester. The summarized results of this study were as follows; First, stretch fabrics, almost, shown high stretch in weft inserted polyurethane yarn fabric and had a ${\pm}2{\sigma}$(sigma) range of shearing, compression, surface and thickness, except bending and weight, as compared with Japanese women's thin dress fabrics. Second, bending had a positive correlation in stiffness, anti-drape and flexibility & softness. Shearing had a negative correlation in crispness and scroop. Surface properties had a high contribution in fullness & softness. Third, The drape coefficient was found by measuring the mechanical properties according to the obtained regression equation. Forth, many problems are expected in overfeed and cutting operations in sewing process. In the decision of the good external appearance using TVA, only 26 of 55 samples are included in the range of the good external appearance. Fifth, in the regard of the result for sewing control, warp values are not necessary to control in the all kind of items. But weft value in the RT and EM are out of non-control zone. So we need a special management during sewing process.
