Dyeable polypropylene (PP) fibers for clothes having improved processing properties such as spinning properties, knitting or weaving properties, dyeability are provided, which fibers are obtained by having (a) a 5-20C alkyl phosphate salt or (b) a mixture thereof with an adduct of ethylene oxide to a 6-20C fatty acid in a proportion of the adduct of 1-90% by weight, attached onto dyeable PP fibers obtained by blending a copolymer of an aminoalkyl acrylate with ethylene with a PP and carrying out melt-spinning using the blend as at least one component of the resulting dyeable PP fibers, the amount of (a) or (b) attached onto the fibers in terms of % by weight of the fibers being adjusted so as to satisfy the following expression: [Figure] wherein d represents the denier of single fiber.

Dyeable polypropylene fibers for clothes comprising: a fiber-finishing agent including a mixture of an adduct obtained by adding ethylene oxide to a saturated or unsaturated fatty acid of 6-20 carbon atoms in a proportion of ethylene oxide of 2 to 25% by mol with an alkyl phosphate salt in a proport

Dyeable polypropylene fibers for clothes comprising: a fiber-finishing agent including a mixture of an adduct obtained by adding ethylene oxide to a saturated or unsaturated fatty acid of 6-20 carbon atoms in a proportion of ethylene oxide of 2 to 25% by mol with an alkyl phosphate salt in a proportion of said adduct of 1-90% by weight, the fiber finishing agent attached onto dyeable polypropylene fibers obtained by blending a copolymer of an amino alkyl acrylate with ethylene with a polypropylene and carrying out melt-spinning using the resulting blend as at least one component of the resulting dyeable polypropylene fibers, the amount of said fiber-finishing agent mixture attached onto said dyeable polypropylene fibers in terms of percent by weight based on the weight of said dyeable polypropylene fibers being adjusted so as to satisfy the following express: [Figure] wherein d represents the denier of the single fiber.
