1. A method for producing a denim-effect garment, the method comprising:
1) Printing a reactive dye ink onto a polyethylene terephthalate (PET) film to form a pattern thereby obtaining a transfer printed PET film;
2) transfer printing a base pulp-treated fabric by attaching the transfer printed PET film thereby obtaining a denim-effect fabric;
3) cutting, sewing, washing to soften, and drying the denim-effect fabric, thereby obtaining a denim-effect garment;
wherein a dye of the reactive dye ink comprises one or more of K-type dye, M-type dye, KN-type dye and P-type dye; and a mass fraction of the dye of the reactive dye ink is 5%;
wherein the base pulp-treated fabric is woven from at least one of cellulose fiber and regenerated cellulose fiber; a temperature of the transfer printing in step 2) is 10° C., a pressure of the transfer printing in step 2) is 0.1 MPa to 0.8 MPa, and a speed of the transfer printing in step 2) is 2 m/min to 25 m/min.
