Abstract

PURPOSE: The titled fiber for spring and summer in which the cross section has a plurality of symmetric projections and depressions and the depressed surface draws a circular arc from the center, further the radius, the distance from the center to the projection and the filament thickness are made in a specific range, thus giving appearance and dry touch like ramie.
CONSTITUTION: An acrylic polymer such as acrylonitrile-methyl acrylate-sodium methallylsulfonate terpolymer is dissolved in 67% nitric acid aqueous solution to prepare a spinning dope. The dope is extruded through a cross-type nozzle of slit length (a) and slit width (b) into a coagulation bath of 34% nitric acid solution at 0°C to produce the objective modified-cross section fiber that is composed of simmetric four projected and depressed surfaces where the depressed surface draws a circular arc of radium (r) from the center of the cross section, the relation between the radius (r) and the distance from the center to the projection part R satisfied the equation and the filament thickness is less than 10 denier.
