COMBINED POLYESTER FILAMENT YARN, HAVING DIFFERENT YARN LENGTH AND GOOD IN COLOR DEVELOPING PROPERTY

摘要

PURPOSE: To obtain polyester yarn capable of simultaneously satisfying high color developing properties and excellent hand. ;CONSTITUTION: The objective yarn is characterized in that it is combined filament yarn composed of two kinds of fibers having different lengths and yarns having ≥3% to ≤25% difference in yarn length; at least one kind of the fiber groups has ≥3 wedgy grooves 3 continuous in the fiber axial direction and the shape of the grooves is specified. This yarn is good in color developing properties. Since the yarn is the combined filament yarn composed of the two or more kinds of fiber groups having the difference in yarn length and at least the one kind of the fiber groups has a specific cross-sectional shape, the knitted and woven fabric prepared therefrom has rich fullness, softness and drapeability and color of the dyed product has the depth. Furthermore, color developing properties excellent in brightness are exhibited even in the case of a chromatic color.;COPYRIGHT: (C)1994,JPO&Japio
