Definitions
- This application discloses a blurring or decoloring agent and a method for manufacturing cloth products.
- Patent Documents 1 to 8 techniques for discharging dyes from printed or dyed cloth are known.
- a discharge paste containing a reducing agent such as stannous chloride or an alkali compound is printed on a fabric that has been undercoated, and after applying heat with steaming to decompose the dye only on the applied part, the decomposed dye is soaped. and remove the glue.
- a printing method in this case an inkjet device may be used in addition to textile printing.
- an aromatic solvent called a carrier agent may be used as an auxiliary agent.
- the present application provides At least one compound selected from the group consisting of a compound represented by the following general formula (1) and a compound represented by the following general formula (2), Used for blurring or decolorizing fabrics printed or dyed with disperse dyes, A blurring or bleaching agent is disclosed.
- X is an alkylene or alkenylene group having 2 to 4 carbon atoms

本開示の暈しもしくは脱色加工剤は、分散染料によって印刷又は染色された布の暈しもしくは脱色加工に用いられる。印刷や染色の手段は問わない。分散染料によって印刷された布の具体例としては、捺染布、インクジェット印刷布、昇華転写布等が挙げられる。布は分散染料によって模様や文字等が形成されたものであってもよいし、分散染料によって印刷又は染色された無地の布であってもよい。

本開示の技術は、分散染料によって印刷又は染色された布に対して、上記の暈しもしくは脱色加工剤を用いて暈しもしくは脱色加工を施すことで、新たな布製品を製造する方法としての側面も有する。
布に暈しもしくは脱色加工剤を接触させる方法は特に限定されるものではない。例えば、布を暈しもしくは脱色加工剤に浸漬した後に布を取り出して絞ってもよいし、布に暈しもしくは脱色加工剤を印刷、塗布又は噴霧してもよい。より具体的には、暈しもしくは脱色加工剤を布に滴下(インクジェットを含む)してもよいし、刷毛塗りしてもよいし、パディングしてもよい。或いは、暈しもしくは脱色加工を施す布に対して、暈しもしくは脱色加工剤を含浸した素材(紙や布等)を当ててもよい。
加熱は公知の加熱手段により実施すればよい。加熱手段としては、例えば、アイロン、ホットプレート、スチーミング、乾熱処理等が挙げられる。加熱温度は、暈しもしくは脱色加工剤とともに分散染料の移動が生じる温度であればよい。加熱温度は、120℃~220℃であってもよい。前記加熱温度の下限は120℃以上又は150℃以上であってもよく、上限は220℃以下又は200℃以下であってもよい。前記加熱温度での加熱時間は、目的とする暈しもしくは脱色加工の程度に応じて適宜決定されればよい。前記加熱温度での加熱時間は、30秒~10分であってもよい。前記加熱温度での加熱時間の下限は、30秒以上又は1分以上であってもよく、上限は10分以下又は3分以下であってもよい。
本開示の方法は、上記の接触及び加熱に係る工程を含むものであればよく、これらに加えてその他の工程を含んでいてもよい。
本開示の方法においては、布と暈しもしくは脱色加工剤とを接触させる前に、当該布を水で予め湿らせておいてもよい。これは、布に対する暈しもしくは脱色加工剤の濡れ広がり性の制御の一助となり、また、加工後の生地の硬さの制御に寄与する。布に対する水の量は特に限定されるものではない。
上記の接触及び加熱を行う際、暈しもしくは脱色加工対象である布における液相や気相の流動を制御してもよい。例えば、布に対して何らかの物体を接触させることで、布における液相や気相の流動を制御してもよい。当該物体は、上記の暈しもしくは脱色加工剤に対して耐性を有し、且つ、上記の加熱に耐えられるものであればよい。当該物体の材質は、特に限定されるものではなく、布や紙であってもよいし、これ以外の材質(金属、セラミック、プラスチック等)であってもよい。また、当該物体の形状は特に限定されるものではなく、例えば、シート状であってもよいし、これ以外の形状であってもよい。布に対する物体の接触位置についても特に限定されるものではなく、例えば、布の一面側、他面側、又は、一面側及び他面側の両方に、物体を接触させることで、布における液相や気相の流動を制御してもよい。また、布に物体を接触させる場合において加熱手段は当該物体と同じ側に配置されていてもよいし、当該物体とは反対側に配置されていてもよい。
本発明者の知見によると、本開示の暈しもしくは脱色加工剤を用いて布の脱色加工を行う場合、脱色加工中の布に対して、あて布等を接触させつつ加圧することで、脱色効率が一層高まる。具体的には、分散染料によって印刷又は染色された布に対して、本開示の暈しもしくは脱色加工剤を接触させた状態で加熱する際、あて布や紙等の分散染料が付着し得る物体を前記布に接触させ、且つ、前記布を加圧することで、前記布から前記物体へと分散染料を容易に移動させることができる。その結果、布から分散染料を効率的に除去することができ、脱色加工後に布に残存する分散染料の量を一層低減することができる。さらに、分散染料によって印刷又は染色された布に対して、本開示の暈しもしくは脱色加工剤を接触させた状態で加熱する際、(1)当該布をあて布や紙等の分散染料が付着し得る物体に接触させること、及び、(2)当該布を加圧することに加えて、(3)布に対する暈しもしくは脱色加工剤の付着量が、例えば、10%o.w.f.以上200%o.w.f.以下、好ましくは、50%o.w.f.以上150%o.w.f.以下であることで、脱色効率が一層高まり易い。布に加えられる圧力の値は、特に限定されるものではないが、例えば、20gf/cm2以上1000gf/cm2以下である場合に脱色効率が一層高まり易い。好ましくは50gf/cm2以上500gf/cm2以下であり、より好ましくは50gf/cm2以上450gf/cm2以下である。布を加圧するための手段は特に限定されるものではなく、公知の熱プレス機等が採用されればよい。
上記の接触及び加熱等を行った後は、任意の冷却工程を経た後で、布を洗浄して、当該布から暈しもしくは脱色加工剤を除去したうえで、乾燥させてもよい。例えば、上記の接触及び加熱等を経た布を水洗したり、溶剤に浸漬することで、布に付着した暈しもしくは脱色加工剤を容易に除去可能である。尚、本開示の方法において、布に対して暈し加工を施した場合、当該布の洗浄時、分散染料は当該布に定着した状態にあり、暈しもしくは脱色加工剤を優先的に除去することができる。
以上の通り、本開示の技術によれば、従来の抜染とは異なるメカニズムによって、布に付着した分散染料を移動させたうえで布に再定着させることができ、布に付着した分散染料を移動させたうえで別の素材に再定着させることもできる。例えば、本開示の技術によれば、布に付着した分散染料を布の面方向に移動させたうえで布に再定着させることもできるし、また、布の片面側に偏在している分散染料を他面側に移動させたうえで(すなわち、布の面方向と交差する方向(布の厚み方向を含む)に分散染料を移動させたうえで)当該布に再定着させることもできるし、布に付着した分散染料を移動させて布を脱色することもできる。そのため、分散染料によって布に形成された模様等を暈しもしくは脱色したり、変化させたりすることが容易である。また、本開示の技術によれば、当初布地の表側の面にしか染色されていなかった場合でも、裏側に模様を見せるように分散染料を移動させること(布の厚み方向への暈し)もできる。また、本開示の技術によって暈しもしくは脱色加工が施された後の布に対しては、さらに別の絵柄を容易に印捺することもできる。
分散染料によって印刷されたポリエステルプリント布に、所定の化合物を滴下して接触させうえで、当該布をアルミニウム箔で挟み込み、アイロンを当てて180℃で2分間加熱した後、布を水洗して乾燥させた。滴下した化合物の種類、及び、布に対する当該化合物の滴下量(%o.w.f.)については下記表1の通りである。
5級:もとの模様が暈されて判別できない。
4級:もとの模様の一部が残るが大部分が暈されてほとんど判別できない。
3級:もとの模様の部分的な移動や消滅があり、もとの模様を判別し難い。
2級:もとの模様に微小な滲みが生じたものの、もとの模様を判別できる。
1級:色調変化が生じたのみで、模様に実質的な変化がなく、もとの模様を容易に判別できる。
ポリエステルニットの昇華転写布に、ニューソルブ RPDEを100%o.w.f.滴下し、布の大きさに合わせた紙(定性濾紙No.2)を上に置いて、熱プレス機(Pony50 ジャパンポリマーク社製)で、400gf/cm2の圧力下、180℃で1分の加熱処理を行った。その後濾紙を外した後、ニューソルブ RPDEを再度滴下し、新たな濾紙を置いて同様の処理をさらに2回繰り返すことで、布に対して脱色加工を施した。脱色加工後の布をアセトンで洗浄し乾燥して、布に残存する分散染料の状態を観察した。図2に、脱色加工前後の布の状態を示す。図2に示されるように、脱色加工後において布に分散染料はほとんど残っておらず、脱色加工により白色のポリエステルニットが得られた。
実施例1~5に示される結果から、下記一般式(1)で表される化合物を用いた場合に、高い暈しもしくは脱色効果が期待できることが分かる。
