能な状況にあった。2. Description of the Related Art Polypropylene has no dyeability, and a stock solution coloring method using a pigment is used to obtain colored fibers, and colored polypropylene fibers produced by other methods have not been produced on an industrial scale. By coloring with a pigment, it is possible to produce fibers with high durability such as weather resistance, rub resistance, and washing resistance, but lacks sharpness on the hue side, and is used for dyeing fibers such as nylon, acrylic, and polyester. In comparison, it was impossible to produce beautiful colored fibers.

ることができる。According to the present invention described above, polypropylene fibers which could not be dyed by a dye but could be colored only by undiluted coloring with a pigment can be sharpened by using a undiluted coloring method using a water-soluble dye. Provided is a polypropylene colored composition capable of producing a colored polypropylene fiber having a hue and high washing fastness. Unlike raw dyed polypropylene fibers, which have poor clarity, creating crisp and beautiful polypropylene fiber products similar to other dyed fibers such as polyamides will allow us to enter the garment field by taking full advantage of the lightweight properties of these fibers. That is enough to make it possible. The polypropylene colored composition of the present invention can be used not only for producing fibers but also for producing colored articles such as colored molded articles having excellent clarity.
