Abstract:
An acrylic fiber tow is disclosed which comprises 1) monocomponent filaments of each of two acrylonitrile polymers differing in hydrophilic properties, 2) bicomponent filaments of both of said polymers having one interface between polymers components and 3) bicomponent filaments of both of said polymers having more than one interface between polymer components. This fiber, however, in spite of its composition of numerous filaments of differing structure provides a tow bundle having a desirable level of reversible crimp measured in a manner specific to the type of crimp designated. Also disclosed is a method for wet-spinning the novel fiber using a static mixing unit in conjunction with a spinnerette normally used for wet-spinning monocomponent filaments.
