CLOTH HAVING CONFIGURATIONAL STABILITY AND/OR WATER RESISTANCE, AND CORE/SHEATH TYPE COMPOSITE THREAD USED THEREFOR

摘要

A core-sheath composite yarn characterized in that a softening point of a core component as measured by thermomechanical analysis of JIS K 7196 is at least 20 DEG C lower than a softening point of a sheath component, and the core component is formed of a substantially amorphous polymer that does not provide a melting point peak as measured by differential thermal analysis of conducting heating in a nitrogen atmosphere at a rate of temperature rise of 10 DEG C/min, and a fabric obtained by using such a composite yarn. This fabric has an excellent shape stability and an excellent water resistance by heat-setting.
