This study was carried out to investigate the silhouette and total hand value(THV) of cotton/PET mixture fabric, and to study the dyeing on these properties. Specimen was union-dyed with reactive dyes for the portion of cotton and disperse dyes for the portion of polyester under two bath system. Mechanical properties of specimens were measured by KES-FB system. The silhouette types were derived from the standardized canonical discriminant function proposed by Niwa. THV of the specimens which belong to Drape and Hari type was calculated by Niwa's new equations, KN-305-DLDY and KN-305-HLDY respectively.
The results were as follows:
1. In terms of mechanical properties EM and tensile energy in tensile properties and bending properties of PET yarns were higher than those of cotton yarn before and after dyeing. After dyeing. cotton/PET fabrics showed lower values of tensile, bending, and surface properties. As the result the specimen became to be more elastic, more flexible, and smoother.
2. Silhouette type of cotton/PET fabric was Hari before and after dyeing. But the standardized values of bending rigidity and shear stiffness were inclined to move to the ranges of those of Drape type fabrics after dyeing.
3. THV of cotton/PET after dyeing increased a little but was about the same to that before dyeing
