However, under the present circumstances, the fibers are easily yellowed by light or heat, and are subject to various practical restrictions. In particular, modacrylic fibers containing chlorine as a copolymerization component have a problem that they are easily yellowed by light or heat.

のが現状である。In order to improve such a problem, for example, Japanese Patent Publication No. 2-15642 discloses a modacrylic fiber containing an ultraviolet absorber which is a benzotriazole compound,
Japanese Unexamined Patent Publication No. 2-33315 proposes modacrylic fiber to which organic tin is added, but in the case of wet spinning, the yield is poor due to the elution of the ultraviolet absorber and organic tin into the coagulation bath. There is a problem that the dyeability is adversely affected. Further, the use of rutile-type titanium dioxide to improve light resistance is performed in the paint field, but when applied to fibers, there is a problem in hardness and spinning operability, and in the fiber field, rutile-type dioxide is used. The current situation is that titanium is not used.

超えると紡糸が困難となる。The rutile type titanium dioxide used in the present invention is required to have a particle size of 0.45 μm or less. If the particle size exceeds 0.45 μm, the operability is remarkably deteriorated and the light resistance is not improved. In addition, silicon (S
It is necessary for i) to be contained in an amount of 2.0% by weight or more as SiO 2 with respect to the amount of titanium dioxide, which improves the dispersibility in the dispersion medium and makes the dispersion of titanium dioxide in the fiber uniform. Good light resistance is obtained, and hardness is hardly affected. When silicon is less than 2.0% by weight as SiO 2 , dispersibility in the dispersion medium is poor and dispersion in the fiber becomes non-uniform, which causes a problem in operation.
Furthermore, it is necessary that the rutile titanium dioxide is contained in an amount of 0.1 to 5.0% by weight based on the acrylonitrile polymer. If the amount of rutile titanium dioxide is less than 0.1% by weight, good light resistance cannot be obtained, and if it exceeds 5.0% by weight, spinning becomes difficult.
