Production method for garment, dyed cloth, and chemical agent

Abstract

[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.

1 . 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. 
     
     
         2 . The garment production method according to  claim 1 , wherein the temperature of the heat treatment is from 150° C. to 200° C. 
     
     
         3 . The garment production method according to  claim 1 , wherein the temperature of the heat treatment is from 160° C. to 180° C. 
     
     
         4 . The garment production method according to  claim 1 , wherein the heat treatment is a laser machining treatment. 
     
     
         5 . The garment production method according to  claim 1 , wherein the garment which uses a dyed cloth containing an alkanolamine is a garment which uses a dyed cloth obtained by contacting with a solution containing an alkanolamine, or a garment obtained from a dyed cloth obtained by contacting with a solution containing an alkanolamine. 
     
     
         6 . The garment production method according to  claim 5 , wherein the solution containing an alkanolamine further comprises a pH adjusting agent. 
     
     
         7 . The garment production method according to  claim 5 , wherein the solution containing an alkanolamine further comprises an organic acid. 
     
     
         8 . A dyed cloth containing an alkanolamine. 
     
     
         9 . The dyed cloth according to  claim 8  for performing decolorization by means of a heat treatment. 
     
     
         10 . The dyed cloth according to  claim 9 , wherein the heat treatment is a laser machining treatment. 
     
     
         11 . The dyed cloth according to  claim 8 , further comprising a pH adjusting agent. 
     
     
         12 . The dyed cloth according to  claim 8 , further comprising an organic acid. 
     
     
         13 . 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. 
     
     
         14 . The chemical agent according to  claim 13 , wherein the chemical agent containing an alkanolamine further comprises a pH adjusting agent. 
     
     
         15 . The chemical agent according to  claim 13 , wherein the chemical agent containing an alkanolamine further comprises an organic acid. 
     
     
         16 . The chemical agent according to  claim 13 , wherein the heat treatment is a laser machining treatment.
