Abstract

PURPOSE: The titled fibers, consisting of plural protruding polyester parts in the symmetry of rotation and recesses of an easily hydrolyzable polyester filling the gaps therebetween, containing fine porous silicate particles, having improved feeling and dyeability, and capable of giving a deep color tone.
CONSTITUTION: Fine porous silicate particles are added to at least one of (A) a polyester, e.g. polyethylene terephethalate, and (B) a polyester having a higher hydrolysis rate with an aqueous solution of an alkali than the component (A), e.g. polyethylene terephthalate copolymer with 5-sodium sulfoisophthalate, and the resultant mixture is then melt spun to subjected to the composite melt spinning to give composite fibers (b). The resultant fibers (b) are then treated with an aqueous solution of an alkali to hydrolyze the component (B) partially and give the aimed fibers (a) having plural protruding parts consisting of the component (A) at the position of symmetry in rotation and recesses consisting of the component (B) filling the gaps between the protruding parts, and containing at least one of the components (A) and (B).
