ABSTRACT:
A viscose rayon fiber provided with a superior appearance such as a silk-like appearance by arranging a number of microfine stripes over all of the surface of the fiber, and a manufacturing method thereof. This fiber can be used as a fiber constituting a filament, and as a staple fiber.
A viscose rayon filament provided with a superior appearance such as a uniform appearance without nonuniformity by forming each fiber of the filament with a cross sectional shape which is independently different from an irregular state in an axial direction of the filament, and a manufacturing method thereof. This application includes a viscose rayon filament including the features of the two above inventions and a manufacturing method. The viscose rayon fiber and the viscose rayon filament in accordance with the present invention can be broadly used for various applications as products having a superior appearance and quality.
