Abstract
PURPOSE: To obtain a fiber having improved water absorbing and mechanical properties, by the wet composite spinning of two types of polymers with different acrylonitrile contents under specific conditions to impart a microporous structure to one component and a dense structure to the other component.
CONSTITUTION: A solution of polymer A containing 90% or more acrylonitrile and a solution of polymer B containing 88% or less acrylonitrile are subjected to the composite spinning of the side-by-side or sheath-core type. The extruded fiber is then coagulated at 3W15°C in the case of an inorganic salt solvent, e.g.sodium rhodanate, washed with water, hot-drawn, heat-treated in the wet state, and dried at 80W130°C. According to the method, a water absorbing acrylic fiber in which one component polymer A is microporous and the other component polymer B is of dense structure can be obtained.
