Definitions
- the present invention relates to a production method for a decolorized garment, and a dyed cloth and a chemical agent to be used in the production of such a garment.
- a dyed fiber product is a fiber product using a denim cloth, typified by jeans, etc.
- a denim cloth typified by jeans, etc.
- the feeling of a new product that has just been dyed is sometimes desired, but consumers widely prefer a fabric that has been nicely faded due to use, or a fabric that has a vintage feel that comes with age.
- it takes too much time to impart a fabric with a vintage feel by means of actual use, and with used clothing the fabric might actually be damaged, or there may be no demand from customers that do not like used clothing. Therefore, many methods for imparting a vintage feel by subjecting a new cloth, etc. to a decolorization treatment in advance have been widely researched.
- Some conventionally used decolorization methods include a method of blurring or scraping the dye in the fiber product to be decolorized through physical friction such as a stonewashing method, a sandpaper and grinding method, and a sandblasting method, as well as a method of chemically decolorizing the fiber product by submerging a pair of jeans, etc., in a prescribed chemical liquid of an electrolytic bath, and the like.
- Patent Document 1 As a means for solving the problems found in these physical and chemical methods, a method of irradiating a laser onto a location to be decolorized has been disclosed (for example, see Patent Document 1 below).
- a method achieved by laser irradiation imparts whiteness to a denim cloth by decomposing the indigo dye on the surface of the cloth with the laser.
- Patent Document 1 JP H10-102386 A
- 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 a laser or the like and which can be efficiently decolorized, a dyed cloth to be used in the production of decolorized garments, and a chemical agent to be used in the decolorization of dyed cloth.
- a dyed cloth can be decolorized from the depths thereof while preventing deterioration of the cloth by performing a heat treatment with a means such as a laser on the dyed cloth which comprises a specific chemical agent, and thereby the present invention was completed.
- the present invention is specified by the matters shown below.
- a garment production method characterized by decolorizing a garment which uses a dyed cloth containing an alkanolamine with a heat treatment.
- 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.
- 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 chemical reagent, an alkanolamine into a garment which uses a dyed cloth.
- FIG. 1( a ) illustrates a pair of jeans which have been subjected to decolorization processing as obtained in Example 1.
- FIG. 1( b ) illustrates a pair of jeans which have been subjected to decolorization processing as obtained in Comparative Example 1.
- FIG. 2( a ) illustrates a pair of jeans which have been subjected to decolorization processing as obtained in Example 2.
- FIG. 2( b ) illustrates a pair of jeans which have been subjected to decolorization processing as obtained in Comparative Example 2.
- FIG. 3( a ) illustrates a pair of jeans which have been subjected to decolorization processing as obtained in Example 3.
- FIG. 3( b ) illustrates a pair of jeans which have been subjected to decolorization processing as obtained in Comparative Example 3.
- the garment production method of the present invention is characterized by decolorizing a garment which uses a dyed cloth containing an alkanolamine with a heat treatment.

- a solution containing an alkanolamine i.e. a chemical agent containing an alkanolamine; the same meaning will apply hereinafter in the specification of the present application
- the former garment (the garment which uses a dyed cloth obtained by contacting with a solution containing an alkanolamine) indicates a garment obtained by incorporating an alkanolamine into a garment produced by cutting and sewing, etc. a dyed cloth that does not contain an alkanolamine.
- the latter garment (garment obtained from a dyed cloth obtained by contacting with a solution containing an alkanolamine) indicates a garment produced by cutting and sewing, etc. a dyed cloth that contains an alkanolamine.
- the dyed cloth which is a textile of a garment to be used in the production method of the present invention generally indicates a thick woven fabric of a cotton material obtained by twill weaving warp yarns of at least 10-count, which have been dyed by a natural or synthetic indigo dye or a sulfur dye, and non-dyed unbleached yarns as the weft yarns.
- fibers used for the above-mentioned yarns mention may be made of cellulose-based natural fibers such as cotton, cellulose-based semi-synthetic fibers such as acetate, cellulose-based regenerated fibers such as rayon and cupra, and mixtures of these fibers with synthetic fibers, etc.
- the type of the denim cloth is not particularly limited, and mention may be made of right-hand twill, left-hand twill, broken twill, dungaree, colored denim, coated denim, and stretch denim, etc.
