PROBLEM TO BE SOLVED: To obtain a printed product capable of keeping the crimp characteristics originally possessed by a polypropylene terephthalate-based fiber, and excellent in color development and color fastness by printing a printing paste on a fiber structure including the fiber, and subjecting the printed fiber structure to a steaming treatment under a specific condition. SOLUTION: A prescribed pattern is printed on a fiber structure obtained by mixtng >=20 wt.% latently crimpable type polypropylene terephthalate-based fiber composed of a bimetal-type conjugate fiber, with a nylon and/or an elastic fiber, by an overprint method or a discharge printing method, and the printed product is subjected to a color-developing treatment in a superheated steam of 140-160 deg.C, preferably 150-160 deg.C for 5-10 min, or in a saturated steam at 110-120 deg.C for 5-45 min, preferably 15-30 min to provide the objective printed product.
