[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.
A garment production method characterized by using a heat treatment to decolorizing a garment which uses a dyed cloth containing an alkanolamine with a heat treatment.
A dyed cloth containing an alkanolamine.
A chemical agent containing an alkanolamine, wherein the chemical agent is used for decolorizing, by means of a heat treatment, a garment produced using a dyed cloth into which an alkanolamine has been incorporated using the chemical agent, or a garment resulting from incorporating, with the chemical reagent, an alkanolamine into a garment which uses a dyed cloth.
