    Abstract: PURPOSE:To reduce the fluctuation in spinning and fiber-making properties, and to obtain the title fibers with high productivity, by spinning a streaky dispersion of a mixture of a high polymer electrolyte and an antistatic polymer solutions in an acrylonitrile polymer solution. CONSTITUTION:A solution of a high polymer electrolyte, e.g. a copolymer of a sulfonic acid group-containing vinyl monomer and a hydrophobic vinyl monomer, is mixed with a solution of an antistatic polymer, e.g. a polyalkylene glycol. The resulting mixed polymer solution is divided and joined to an acrylonitrile polymer solution in a static in-line mixer comprising the two helical blades 1 which are set in the pipe 2 and shifted 90 deg. in the intermediate chamber 3 under such conditions at to satisfy the following equations: 0.4logmH+0.66

    Abstract: PURPOSE:The titled composite fiber having improved fiber properties, hand, bulkiness and whiteness, by melt blend spinning of a polymer comprising a copolymer containing carbon black and polyalkylene glycol units and a polymer containing a white pigment under specific conditions. CONSTITUTION:(A) A mixed polymer comprising (a) 30-90wt% a fiber-forming acrylonitrile polymer and (b) 10-70wt% a copolymer containing carbon black and polyalkylene glycol units and (B) a fiber-forming acrylonitrile polymer containing a white pigment at a weight ratio between (A) and (B) of 1:99-10:90 are mixed and spun into the objective composite fiber wherein part of the component (A) is opened and exposed to the surface of the fiber and the opened and exposed area is smaller than the contact area between the components (A) and (B). A polyether-polyester block copolymer may be preferred as the component (b).
