Abstract
PURPOSE: The titled lightweight fibers, consisting of specific amounts of acrylic polymer and a polyvinyl alcohol derivative both present in the state of phase separation, and having a specific porosity and surface area and improved water absorbing and heat insulating properties.
CONSTITUTION: A spinning solution prepared by dissolving (A) 70W98wt% acrylic polymer and (B) 2W30wt% polyvinyl alcohol derivative, e.g. polyvinyl butyral, in dimethylformamide, etc. is extruded into a coagulation bath consisting of dimethylformamide, water, etc. to form fibers, which are then washed with water, dried and drawn to give the aimed fibers, consisting of the components (A) and (B) in the state of phase separation, and having a porosity (V) of 0.05W0.7cm3/g and a pore surface area (S)≤15m2/g. The component (A) preferably contains at least 80wt% acrylonitrile.
