[Problem] The present invention addresses the problem of providing: a method for producing garments that use dyed cloth on which whiteness easily emerges due to heating by irradiation with laser or the like and which can be efficiently decolorized; dyed cloth used in production of decolorized garments; and a chemical agent used in decolorization of dyed cloth. [Solution] This production method for garments is characterized by using a heat treatment to decolorize garments which use dyed cloth containing an alkanolamine. The temperature of the heat treatment is preferably 160-180° C., and the heat treatment is more preferably a laser machining treatment.

Polyester-free cotton is obtained from a fabric and/or fibers containing polyester and cotton by reacting the fabric and/or fibers with an amine organocatalyst and/or carboxylic acid salt of same and an alcohol solvent. The reaction, which may be run in batches or as a continuous flow process, recovers (i) polyester-free cotton as a solid inert by-product of the reaction, (ii) the amine organocatalyst and/or carboxylic acid salt of same for reuse, (iii) a polyester monomer product, and (iv) unreacted alcohol. The reaction works on any polyester-cotton fabric and/or fibers, including those that have at least one additional material, such as polyethers polyolefins, polyurethanes, nylon, rayon, acetate, viscose, modal, acrylic, wool, and combinations thereof.
