[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.

衣類の製造方法、染色生地及び薬剤Clothing manufacturing methods, dyed fabrics and chemicals
　本発明は、脱色された衣類の製造方法、その衣類の製造に用いる染色生地及び薬剤に関する。 The present invention relates to a method for producing decolorized clothing, a dyed fabric and a chemical used for producing the clothing.
　染色された繊維製品の一つに、ジーンズ等に代表されるデニム生地を使用した繊維製品がある。ジーンズ等は、染色されたばかりの新品の風合いが好まれることもあるが、着用による程よい色落ちが入ったものや年代物等のビンテージ感が表れた生地が消費者に広く好まれている。しかし、現実の着用により生地にビンテージ感を出すのには時間がかかり過ぎ、また古着は生地が実際に傷んでいることや、古着を好まない需要者の需要が得られないことから、新品の生地等に予め脱色処理を施しビンテージ感を出す様々な方法が広く研究されている。 One of the dyed textile products is a textile product using denim fabric such as jeans. Jeans and the like may be preferred to have a new texture that has just been dyed, but consumers are widely fond of fabrics that have a moderate discoloration due to wearing or that have a vintage feel such as vintage jeans. However, it takes too much time to give the fabric a vintage look by actually wearing it, and since the fabric is actually damaged and the demand of consumers who do not like used clothing cannot be obtained, new clothing is new. Various methods have been widely studied to give a vintage feel to fabrics and the like by pre-bleaching them.
　従来から用いられている脱色方法としては、ストーンウォッシュ法、サンドペーパ及びグラインド法、サンドブラスト法等と称される、脱色させたい繊維製品の染色を生地への物理的な摩擦で染色をぼかしたり削り取ったりする手法、電解槽の所定の薬液にジーンズ等を浸漬して、繊維製品を化学的に脱色する手法などがある。 Conventionally used decolorization methods include the stone wash method, sandpaper and grind method, sandblasting method, etc., in which the dyeing of textile products to be decolorized is blurred or scraped off by physical friction on the fabric. There is a method of immersing jeans or the like in a predetermined chemical solution in an electrolytic cell to chemically decolorize the textile product.
　ところが、物理的に繊維製品を脱色する手法では、脱色後に繊維に入り込んだ石等を除去するのに手間を要するという問題があった。また、化学的に脱色する手法では、使用した薬液の処理に手間を要するという問題があった。また、従来のいずれの方法についても、生地の所望の位置に正確にかつより自然な風合いでビンテージ感を出すのが難しいという問題があった。 However, the method of physically decolorizing textile products has a problem that it takes time and effort to remove stones and the like that have entered the fibers after decolorization. In addition, the method of chemically decolorizing has a problem that it takes time and effort to process the chemical solution used. In addition, any of the conventional methods has a problem that it is difficult to give a vintage feeling to a desired position of the fabric accurately and with a more natural texture.
　これらの物理的方法、化学的方法が有する問題を解決する手段として、脱色させたい箇所にレーザーを照射する方法（例えば、下記特許文献１）が開示されている。
　レーザー照射による方法は、デニム生地の表面のインディゴ染料をレーザーで分解させることにより生地に白度を持たせている。 As a means for solving the problems of these physical methods and chemical methods, a method of irradiating a portion to be decolorized with a laser (for example, Patent Document 1 below) is disclosed.
In the laser irradiation method, the indigo dye on the surface of the denim fabric is decomposed by a laser to give the fabric whiteness.
特開平１０－１０２３８６号公報Japanese Unexamined Patent Publication No. 10-102386
　しかし、特許文献１等に記載の従来のレーザー照射による方法では、デニム生地の表面にしかレーザーが照射されないため、生地の表面しか脱色することができなかった。したがって、レーザー照射による脱色後に洗浄した場合、レーザー照射された層が剥がれて下方で脱色しきれなかった層が表れてしまうため、白度が出にくいという課題があった。
　そこで、本発明は、レーザーの照射等の加熱により白度が出やすくかつ効率的に脱色可能とする染色生地を用いた衣類の製造方法、脱色される衣類の製造に用いられる染色生地、及び染色生地の脱色に用いられる薬剤を提供することを課題とする。 However, in the conventional laser irradiation method described in Patent Document 1 and the like, since the laser is irradiated only on the surface of the denim fabric, only the surface of the fabric can be decolorized. Therefore, when cleaning is performed after decolorization by laser irradiation, the laser-irradiated layer is peeled off and a layer that cannot be completely decolorized appears below, so that there is a problem that whiteness is difficult to appear.
Therefore, the present invention relates to a method for producing garments using a dyed fabric that easily produces whiteness and can be efficiently decolorized by heating such as laser irradiation, a dyed fabric used for producing garments to be decolorized, and dyeing. An object of the present invention is to provide a chemical used for decoloring a fabric.
　本発明者らは、上記課題を解決すべく鋭意検討した結果、ある特定の薬剤を含有する染色生地をレーザー等の手段で加熱処理することにより、生地を劣化させることを防止しつつ染色生地の奥から脱色できることを見いだし、本発明を完成するに至った。 As a result of diligent studies to solve the above problems, the present inventors have obtained a dyed fabric containing a specific chemical by heat-treating the dyed fabric by means such as a laser to prevent the fabric from being deteriorated. We found that it was possible to decolorize from the back, and completed the present invention.
