Description

【技術分野】
【0001】
本発明は、略すべての繊維からなる複合素材などを、一浴方式で、同色系に、堅牢かつ高品質で染色でき、更に経済性にも優れた染色システムおよび該システムに基づく染色法に関する。
【0002】
更に詳しくは、本発明は、繊維と共有結合する反応染料を、ポリアミド繊維の反応染料による染着性の難易や染色条件などに基づいて分類し、これら分類された反応染料により、又は該反応染料と酸性含金属染料、カチオン染料及び分散染料から適切に選択された染料との組合せにより、反応染料と共有結合し得る単独の繊維素材又は略すべての繊維からなる複合素材を、一浴方式で、同色系に、堅牢かつ高品質に染色することができ、かつ経済性に優れた新規な染色システムおよび該システムに基づく染色法に関する。
【背景技術】
【0003】
近年、健康衣料、機能性衣料や、吸水、速乾および冷感衣料などに、多繊維からなる複合素材が用いられている。そして、繊維染色加工業界は、多繊維からなる複合素材の、高品質、高性能の加工により、競争力の向上を計っている。中でも合成ポリアミド繊維とセルローズ繊維からなる機能性衣料の商品化が、大きな課題とされている。
多繊維からなる複合素材の加工は、複雑で困難を伴うものである。染色工場では、この複合素材を、反応染料と酸性染料、直接染料などを使用して、一浴又は一浴二段染色方式での染色する方法が検討されたが、安定した同色性と堅牢な染色物が得られず、家庭洗濯にも耐えないものしか得られなかった。
【0004】
このため染色工場では、まず綿側を、反応染料を用いて染色し、ソーピングなど後処理を行った後、ポリアミド側を酸性染料、酸性媒染染料を用いて酸性浴で染色するという完全な二浴二段方式で、この染色を実施せざるを得なかった。しかし、この方法は、長時間と多くの操作を要し経済性に乏しい。しかもこの二浴二段方式による染色によっても、染色物の湿潤堅牢度において不充分であり、商品化に限界があった。
本発明者らは、先に、反応染料によるポリアミド系材料の堅牢な染色方法を提案している(特開平7−97777号公報)。この方法は、硫酸ナトリウムを多量に含有する酸性浴又は中性浴で染色することを特徴し、この方法によりポリアミド系材料を、セルローズ繊維と共有結合することができる反応染料を用いて染色することを可能とした。
【0005】
本発明者らは、更に、合成ポリアミド、羊毛、絹及びセルローズ繊維の単独の素材並びに合成ポリアミド、羊毛、絹、セルローズ及び他繊維からなる複合素材を、反応染料を用いて吸尽染色する方法であって、6−ナイロンを染色する場合の染浴pHの影響に基づき、反応染料を酸性反応染料と中性反応染料とに分類し、両者を混合して使用し、同色性を得る均染色方法を提案している(特願2000−388497号)。
しかしながら、その後、難染色性の合成ポリアミドや、逆に吸汗性の合成ポリアミドなど綿よりも染まり易い合成ポリアミドを含有する複合素材の染色が強く要請されるようになり、このように分類された反応染料だけではすべての対応は困難であることが判った。
【0006】
更に、合成ポリアミドの比率が15%以下との非常に低い素材や、染色濃度が0.5o.w.f(被染物重量に対する重量%)以下との極淡色の場合には、合成ポリアミド側が濃く染色されて、同色系の色相が得られても、複合素材表面の均一性に欠けることも判った。更には、ポリエステル繊維、特にポリトリメチレンテレフタレート(PTT)との複合素材やポリアクリル繊維との複合素材など、多数の複合素材が試作され、現実に開発、検討されており、この分野での一浴二段方式での堅牢な染色方法も渇望されている。
そこで、どのような複雑な複合素材についても、堅牢で高品質な染色が達成され、かつ経済性のある合理的な染色方式が望まれていた。
【0007】
本発明者らは、上記事情に鑑み、染色の困難な多くの複合素材においてもすぐれた染色ができる方法を開発するべく、鋭意研究、検討した。その結果、反応染料を、セルローズ繊維へと合成ポリアミド繊維への染色性の差違により分類し、この分類に基づき、被染色素材に適合した一種又は二種以上の反応染料またはその組合せを選択することにより、または該反応染料と酸性含金属染料、カチオン染料もしくは分散染料などの他の染料とを組合せることにより、用いられるすべての染料を一浴に調整して染色する方式で、多くの複合素材について、同色で、堅牢で、かつ高品質の染色物を工業的に有利に得ることができる染色システムを見出し、本発明を完成した。
【発明の開示】
【0008】
本発明は、合成ポリアミド、天然ポリアミド繊維及びセルローズ繊維から選らばれる単独の素材、又は合成ポリアミド及び天然ポリアミド繊維から選らばれる素材及びセルローズ、ポリアクリル及びポリエステル繊維から選ばれる素材を含有する複合素材を染色する吸尽染色方法であって、
セルローズ繊維と合成ポリアミド繊維とを同浴で染色したときの、セルローズ繊維に対する合成ポリアミド繊維の染色物の濃度比及び補正色差による反応染料の分類に基づいて、反応染料の一種又は二種以上を選択し、
該反応染料により、または該反応染料と、酸性含金属染料、カチオン染料及び分散染料から選ばれる染料の組合せにより、かつ用いる染料のすべてを一浴に溶解して、
前記単独の素材又は複合素材を染色することを特徴とする反応染料を用いる染色法である(請求項1)。
【0009】
ここで、セルローズ繊維に対する合成ポリアミド繊維の染色物の濃度比及び補正色差は、6−ナイロンジャージと綿ニット(未シルケット)を、それぞれ約50%づつの重量比率で、硫酸ナトリウム40〜80g/Lを加えたpH6.3〜7.0の染浴(酸無添加の染色)、又は硫酸ナトリウム40〜80g/Lを加え酢酸1%o.w.fを加えた染浴(酸添加の染色)で染色し、得られた染色物を側色したときの、綿染色物に対する6−ナイロンジャージ染色物の色の濃度比、補正色差から求めたものである。
本発明において、反応染料の分類は、この濃度比、補正色差に基づき行われる。本発明は又、上記の方法により濃度比、補正色差を求めることを特徴とする反応染料の分類法をも提供する(請求項15)。
【0010】
また、上記において、天然ポリアミド繊維としては、羊毛や絹が例示される。
含有するとは、列挙された素材以外を含んでいてもよいことを意味する。
染料の組合せとは、二種以上の染料を混合して染浴に加える場合と、二種以上の染料を別個染浴に加えて組合せる場合の両方を意味する。
また、本発明は、前記の反応染料を用いる染色法であって、前記の濃度比及び補正色差による反応染料の分類が、
セルローズ繊維と合成ポリアミド繊維を同浴で、硫酸ナトリウムを添加し、酢酸無添加で染色したときの、
セルローズ繊維に対する合成ポリアミド繊維の染色物の濃度比が150〜600%であり、かつ補正色差が、Black以外の場合は5.0以下、Blackの場合は8.0以下である染料をA類、
濃度比が85%以下であり、かつ補正色差が、Black以外の場合は5.0以下、Blackの場合は8.0以下である染料をC類、
濃度比が85〜135%、かつ補正色差が、Black以外の場合は5.0以下、Blackの場合は8.0以下である染料をSNC類、
濃度比が600%以上、かつ補正色差が3.0以下である染料をSN類、
及び濃度比30%以下、補正色差が3.0以下である染料をSC類とするものであり、
または
セルローズ繊維と合成ポリアミド繊維を同浴で、硫酸ナトリウムを添加し、酢酸添加で染色したときの、
セルローズ繊維に対する合成ポリアミド繊維の染色物の濃度比が100〜300%であり、補正色差が、Black以外の場合は5.0以下、Blackの場合は8.0以下である染料をHP類、及び
濃度比が50〜120%、補正色差が、Black以外の場合は5.0以下、Blackの場合は8.0以下である染料をHQ類とするものであり、
A類、C類、SNC類、HP類又はHQ類に属する染料を染色の主体に用い、SN類、SNC類、SC類に属する染料を調整用染料として用いることを特徴とする反応染料を用いる染色法である(請求項2)。
【0011】
ここで染色の主体とは、繊維の染色において、染色の主要部分を担う染料であり、また、調整用染料とは、染色の主体により染色された後、色相などの調整をするために用いられる染料である。
【0012】
本発明は更に、各種の被染色素材のそれぞれについて、反応染料の分類に基づき適切に選択された反応染料、またはこれと他の染料との組合せによる、以下の染色法を提供する。すなわち、本発明は、前記の反応染料を用いる染色法であって、吸水率10%未満の合成ポリアミド繊維とセルローズ繊維との複合素材を、前記A類に属する染料より選択された一種又は二種以上を使用して染色することを特徴とする反応染料を用いる染色法である。(請求項3)
ここで、吸水率とは、繊維を100%RHの環境におき、繊維内に水分を飽和させた場合の、繊維内の水分の重量%を表す。
【0013】
また、本発明は、前記の反応染料を用いる染色法であって、吸水率10%以上の合成ポリアミド繊維単独の素材、または吸水率10%以上の合成ポリアミド繊維とセルローズ繊維との複合素材を、前記A類に属する染料より選択された一種又は二種以上を使用して染色することを特徴とする反応染料を用いる染色法である。(請求項4)。
【0014】
請求項4の染色法は、染色温度(染浴の温度)40〜90℃の温度範囲で行うことが可能である。すなわち、本発明は、この染色法であって、染色を、40〜90℃の温度範囲で行うことを特徴とする反応染料を用いる染色法である。(請求項5)。
【0015】
従来、合成ポリアミド繊維の染色においては、90℃以上の高温での染色が行われており、又合成ポリアミド繊維とセルローズ繊維との複合素材の染色においては、90℃以上と90℃未満の染色が別浴で、行われていた。上記の染色法においては、染色温度が40〜90℃の範囲の1浴で行えるので、エネルギーコストの節約になるばかりでなく、複合素材の場合には、染色温度の管理が容易になり、しわの発生防止等にもなり、工業的に好ましい。上記の染色法では、ポリアミドを染めやすいA類の染料を用いて、易染色性のポリアミドを染めることになるが、染色温度をこのような低い温度とすることにより、優れた染色が得られることを本発明者が見出したものである。染色温度としては、60〜80℃がより好ましい。
【0016】
また、本発明は、前記の反応染料を用いる染色法であって、前記A類又はSNC類に属する染料より選択された一種又は二種以上の染料、及び、前記C類に属する染料より選択された一種又は二種以上の染料との組合せを使用して、合成ポリアミド繊維とセルローズ繊維との複合素材を染色することを特徴とする反応染料を用いる染色法である(請求項6)。組合せ中の、A類の比率は、10〜90重量%の範囲が好ましい。
【0017】
また、本発明は、前記の反応染料を用いる染色法であって、吸水率10%以上の合成ポリアミド繊維及び天然ポリアミド繊維から選ばれる繊維とセルローズ繊維との複合素材、又は、合成ポリアミド繊維を含有しその比率が約15重量%以下の複合素材を、前記C類に属する染料より選択された一種又は二種以上を使用して染色することを特徴とする反応染料を用いる染色法である。(請求項7)。
【0018】
また、本発明は、前記の反応染料を用いる染色法であって、合成ポリアミド繊維及び天然ポリアミド繊維から選ばれる繊維とセルローズ繊維との複合素材を、
前記C類に属する染料より選択された一種又は二種以上を使用し染色濃度が約0.5%o.w.f程度以下で染色することを特徴とする反応染料を用いる染色法である。(請求項8)。
【0019】
また、本発明は、前記の反応染料を用いる染色法であって、セルローズ繊維及び/又はポリアミド繊維を、
三原色染料、Navy色の染料又はBlack色の染料であり、かつ前記C類に属する染料より選択された一種又は二種以上を使用して染色することを特徴とする反応染料を用いる染色法である。(請求項9)。
また、本発明は、前記の反応染料を用いる染色法であって、合成ポリアミド繊維単独の素材、吸水率10%未満の合成ポリアミド繊維とセルローズ繊維との複合素材、又は羊毛等の天然ポリアミド繊維からなる素材を、
前記A類、C類又はSNC類に属する染料より選択された一種又は二種以上の反応染料と25℃での溶解度が5g/L以上又は80℃での溶解度が50g/L以上であり、かつ合成ポリアミド繊維に染着させた後、無水硫酸ナトリウム30g/L、炭酸ナトリウム10g/L、温度70℃、浴比1:20の染浴条件で30分間処理しても該合成ポリアミド繊維より脱落しない酸性含金属染料より選択された一種又は二種以上との組合せを使用して染色することを特徴とする反応染料を用いる染色法である。(請求項10)。
ここで用いられる反応染料としては、A類に属する染料より選択された一種又は二種以上、又はこれと、C類又はSNC類に属する染料より選択された一種又は二種以上との組合せが好ましい。
【0020】
また、本発明は、前記の反応染料を用いる染色法であって、ポリアクリル繊維とセルローズ繊維の複合素材、又はポリアクリル繊維、合成ポリアミド繊維及びセルローズ繊維との複合素材を、
前記HP類又はHQ類に属する染料より選択された一種又は二種以上の反応染料と、
分散化されたカチオン染料または染浴中で分散化するカチオン染料より選択された一種又は二種以上との組合せを使用して染色することを特徴とする反応染料を用いる染色法である。(請求項11)。
【0021】
また、本発明は、前記の反応染料を用いる染色法であって、ポリエステル繊維とセルローズ繊維との複合素材、又はポリエステル繊維、合成ポリアミド繊維及びセルローズ繊維との複合素材を、
三原色染料、Navy色の染料又はBlack色の染料であって、前記HP類又はHQ類に属する染料より選択された一種又は二種以上の反応染料と、
移染性が良く、合成ポリアミド繊維と綿との複合素材の染色において、同色性がよく、綿汚染が少なく、かつ合成ポリアミド繊維に染着して耐光性の良い分散染料から選択された一種又は二種以上との組合せを使用して染色することを特徴とする請求項2に記載の反応染料を用いる染色法である。(請求項12)。
【0022】
上記の請求項10〜12の染色法において、組合せ中の反応染料の比率は10〜80重量%の範囲が好ましい。
前記の反応染料を用いる染色法の全てにおいて、染色工程の最後に、アルカリ処理を行うことが、堅牢度の向上のために好ましく、多くの場合、非常に重要である。すなわち、セルローズ繊維を含有する複合素材の場合は、セルローズ繊維側のアルカリを含有する染色、セルローズ繊維を含有しない場合であっても、アルカリ処理を染色工程の最後に行い、優れた堅牢度を得る。
【0023】
このように、本発明はまた、前記の染色法であって、セルローズ繊維側のアルカリを含有する染色、又は、アルカリ処理を、染色工程の最後に行うことを特徴とする反応染料を用いる染色法である(請求項13)。
【0024】
前記の反応染料を用いる染色法の全てにおいて、前記の分類に基づいて選択された適切な染料や染料の適切な組合せで染色しても、若干色相、濃度を調整することが好ましい場合がある。その場合は、前記の分類において、SN類、SNC類及びSC類に属する染料から選択された染料(調整用染料)を用いて、色相、濃度の調整や補正を行うことが好ましい。
【0025】
すなわち、本発明はまた、前記の染色法であって、合成ポリアミド繊維側、セルローズ繊維側又は合成ポリアミド繊維側及びセルローズ繊維側の両側の染色を、SN類、SNC類及びSC類の調整用染料を加えて行うことを特徴とする反応染料を用いる染色法である(請求項14)。

【発明を実施するための最良の形態】
【0038】
以下に、本発明について更に詳細に説明する。
本発明者は、複合素材における、合成ポリアミド繊維とセルローズ繊維についての、反応染料の染色性の差異により生じる問題は、両繊維の同浴における染色挙動の解析により反応染料を系統的に分類し、該分類に基づく染料の適切な選択により解決できると想定した。
そして、両繊維の同浴における染色挙動の解析、反応染料の系統的分類は、供せられた被染物のビーカースケールの試し染色によって迅速、適切に決定することができることを見出し、更にこの反応染料の系統的な分類として前記の分類を開発し、又前記の分類法を見出した。より具体的には、前記の反応染料の系統的分類、及び本発明の反応染料の分類法は、例えば、以下の方法により行うことができる。
【0039】
市販の精練された6−ナイロンジャージ(*70d、24F、双糸)5g及び市販の精練された未シルケット加工の綿ニット(*40d、単糸)5gを一緒に、93〜97℃の熱湯100ml中に5分間浸漬し、更にイオン変換水500mlを加えて、十分に浸潤する。これを家庭用遠心脱水機で5分間脱水した後、両者の重量を秤量する。
その重量は、6−ナイロンジャージ6.93±0.14g、綿ニット8.9±0.31g程度となる。
【0040】
この脱水された両者を、200mlの染浴で、常圧回転式の染色機で染色する。染色濃度を、各染料2.0%o.w.f、(生地重量に対する染料の重量%)(ただし、Navy染料の場合は5.0%o.w.f、Black染料の場合は10.0%o.w.f)とし、無水硫酸ナトリウム40g/l、(Navy染料の場合は60g/l、Black染料の場合は80g/l)、温度100℃で40分間染色した後、70℃に冷却し、炭酸ナトリウム20g/lを加えて、更に40分間染色する。そして、排液し、水洗し、80℃で3分間湯洗し、ポリカルボン酸系のソーピング剤2g/l、浴比1:40、95〜100℃で5分間ソーピングし、水洗したのち、乾燥して仕上げる。得られ両者の染色物を、SlCOMUC−20システム(住化分析センター社製)で測色し、綿染色物に対する6−ナイロンジャージの染色物の色の濃度比、補正色差を得る。そして、この濃度比、補正色差により、反応染料を、前記のように分類する。
【0041】
この反応染料の分類で、A類に属する反応染料は合成ポリアミド繊維が明らかに濃く染まる染料で、難染色性の合成ポリアミド繊維とセルローズ繊維との複合素材又は易染色性の合成ポリアミド繊維の堅牢な染色に有利に適用される。ここで、難染色性の合成ポリアミド繊維とは、吸水率が約10%未満の合成ポリアミド繊維を言い、特に吸水率が約8%以下のものを言い、吸水率が約7%の6,6−ナイロン、緻密な組織の6−ナイロンなどが例示される。
【0042】
C類に属する反応染料は綿側が濃く染まる染料で、
易染色性の合成又は天然ポリアミド繊維とセルローズ繊維の複合素材、
0.5%o.w.f以下の淡色分野や合成ポリアミド繊維の含有比率が15%以下の複合素材などに有利に適用できる。
ここで易染色性の合成ポリアミドとは、吸水率が約10%以上の合成ポリアミド繊維を言い、吸汗性の合成ポリアミドが例示され、易染色性の合成ポリアミド繊維とセルローズ繊維の複合素材としては、該合成ポリアミドと綿からなるリバーシブル素材が例示される。
【0043】
また、市販の三原色染料、Navy染料又はBlack染料による、綿単独の染色で、塩素と耐光堅牢度が共に良好な染料が得られていないが、C類に属する染料により、耐光を同等に維持して塩素堅牢度(有効塩素20ppm)を少なくとも1級以上の大きく向上させることができる。また、汗耐光も向上させることができる。前記のポリアミド繊維の場合(優れた堅牢度が得られる)も同様であるが、本発明は、ポリアミド繊維やセルローズ繊維などの単独の素材においても、上記のような優れた効果を発揮する。
【0044】
SNC類に属する染料は、合成ポリアミド繊維とセルローズ繊維の両方が略同等に染まる染料で、両側を同色に均等に染色するのに適しており、染色の主体とともに、合成ポリアミド繊維とセルローズ繊維の両者の色相調整用染料としても用いることができる。
SN類に属する染料は、合成ポリアミドに特に濃く染まり、セルローズ繊維側は僅かしか染色されないので、合成ポリアミド側のみの色相、濃度を調整するのに必要である。
SC類に属する染料は、セルローズ繊維側が著しく濃く染まり、合成ポリアミドは殆んど染まらない染料で、セルローズ繊維側の色相、濃度を調整するのに貴重な染料である。
【0045】
多品種の複合素材を同色に染め得るか否かにとって、どのような染料の組合せを用いるのかの設計が極めて重要であるが、試し染めにより得ることができる前記の分類と用途に従って、適切な種属の染料を選択し、適切な染色処方を容易に決定することができる。
これまではこの様な染料選択方法が無かったために、同色を得る確かな染色処方が組めず、トラブルが多く、二浴二段法で実施せざるを得なかったと思われる。
【0046】
本発明において、前記のように選択される反応染料は、酸性含金属染料等の他の染料と組合せても、用いることができ、以下に述べるような有利な効果が得られる。
【0047】
例えば、A類に属する染料及び適切に選択された酸性含金属染料、必要に応じてC類、SN類、SC類に属する染料との組合せで、ポリアミド繊維、ポリアミド繊維とセルロース繊維の複合素材などの、60〜90℃程度の低温での一浴染色が可能となる。例えば、非常に困難な染色物の例として、反応染料では殆んど染着しない合成ポリアミドからの複合素材、例えばシェープアップパンツ等があるが、これらをこの組合せにより、好適に染色することができる。
【0048】
選択される酸性含金属染料は、相当量の硫酸ナトリウムを含有する染浴で染色するので溶解性が良いこと、綿汚染が少ないこと、そして重要な性能として綿側の染色条件である炭酸ナトリウム10g/L、70℃、30分の処理でポリアミド繊維に染着している酸性含金属染料が脱着しないものであり、10%程度以下しか脱落しないものが好ましい。溶解性については、25℃で5g/L以上、又は、80℃で50g/L以上の溶解度が必要である。
選択された酸性含金属染料と反応染料との混合又は組合せは、繊維素材の染色性によって任意に決定できるが、酸性含金属染料で染色速度の近似した三原色染料を組めないので、単独染料又は色相の近似する二原色染料と、前記反応染料の三原色による組合せが有利である。
【0049】
特に酸性含金属染料の、鮮明なYellow染料、Blue染料及び比較的鮮明なRed染料と、A類に属する反応染料のYellow染料、Blue染料及びRed染料との混合は、6−ナイロンの染色で濃度と鮮明度を向上する効果が得られる。また、羊毛の染色においても均染、湿潤堅牢度の向上に効果的である。
【0050】
本発明はまた、ポリアクリル繊維又はポリエステル繊維を含有する複合素材、特に合成ポリアミド繊維、セルローズ繊維との三者の複合素材の一浴での染色加工に適用することができる。このポリエステル繊維には、最近開発されたポリトリメチレンテレフタレート繊維等も含まれる。
これらポリアクリル繊維やポリエステル繊維の、カチオン染料又は分散染料による染色は、酸性浴で行う必要がある。従って、反応染料との組合せで、一浴で染色する場合においても酸性浴が必要である。
そこで、適切な反応染料の選択も、酸添加での染色性による分類に基づくが必要である。前記の反応染料の分類における、HP類、HQ類はこの分類に該当する。
すなわち、前記の反応染料の分類方法に従って6−ナイロンジャージ(東レ社製)50%、綿ニット(未シルケット)50%の重量比率で両者を酢酸1%o.w.fを加えた染浴で染色し、得られた染色物をSICOMUC−20システム(住化分析センター社製)で側色し、綿染色物に対する6−ナイロンジャージ染色物の色の濃度差、補正色差に基づいて分類されたものである。
【0051】
HP類、HQ類に属する染料は、染浴で分散化されたカチオン染料又は分散染料との組合せでポリアクリル繊維及びポリエステル繊維とセルローズ繊維などの複合素材を一浴で同色に染色する方法に特に適する。HQ類として好ましい染料は、前記の濃度比が55〜95%の範囲にあるものである。
ここで、ポリアミド繊維を、HP類は濃く、HQ類は淡く染める染料である。
酸を加えるとナイロン側が濃く染まる反応染料が多いことと、分散染料との組合せでは分散染料がポリアミド側にも一部染まることから、実際の染色では、ポリアミド側を淡く染める染料を用いることが好ましい場合が多い。
ここで用いられるカチオン染料としては、染料の凝集を起こさない分散化されたカチオン染料が望ましい。また、必要に応じて、前記A類、C類から選択された反応染料なども併用できる。
【0052】
また、ポリエステル繊維を染める分散染料としては、移染性が大きく、セルロース繊維に残らない分散染料、合成ポリアミド繊維に一部染着してもその耐光堅牢度が良い分散染料が特に好ましい。本発明の一浴に調整される染料は単独の染料又は混合染料で用いられるが、所定の混合比は、染色浴で調整することも出来る。
【0053】
染色物の堅牢度は、その商品化において、重要であり、少なくとも家庭洗濯に耐える湿潤堅牢度を必要としている。特に新商品では30回の洗濯に耐えることが重視されている。
前記のように、湿潤堅牢度には、染色工程の順序が重要な影響を与え、先ず合成ポリアミド繊維の染色をし、最後に綿等のセルローズ繊維の染色をすることが効果的である。
すなわち、綿の染色は炭酸ナトリウムなどアルカリ浴で処理されるが、これによって綿が膨潤されて綿を汚染している染料や合成繊維表面の未染着染料を除去される効果がある。引き続いて水洗、湯洗、そしてソーピング工程により、堅牢度が向上する。つまり、この工程は、綿と染料の化学結合による固着と不用な汚染染料除去という二つの役割をなしている。これが逆に綿の染色から始めると、この効果が得られないので、やむを得ずこの順序が採れない場合であっても、炭酸ナトリウム2〜10g/L、無水硫酸ナトリウム20〜100g/Lからなる浴で60〜70℃で5〜30分程度のアルカリ処理を行うことが好ましい。
【産業上の利用可能性】
【0054】
本発明の染色システム、染色法により、ほぼすべての繊維からなる複合素材の染色、特に従来は2回(二浴方式)、3回(三浴方式)の染色を順に行っても十分な染色が得られない複雑で困難な染色においても、1回(一浴方式)で高品質、高堅牢度の染色が可能となる。
一浴方式での染色が可能であるので、これまでの二浴二段の染色方式より染色廃水の削減、省エネルギー、省力化となり、工場スケールの標準的な染色で比較して、少なくとも約30%のコスト削減と約40%の時間短縮が可能となり、その経済的効果は計りしれないものがある。
しかも一浴方式の本発明による染色物の諸堅牢度は極めて優秀である。すなわち、二浴方式では、ポリアミド繊維と酸性染料がイオン結合しているのに対し、本発明の一浴方式では、反応染料は、ポリアミド繊維のアミノ其と化学結合(共有結合)しており、諸堅牢度の向上に寄与している。特に、染色工程の最後に、アルカリ処理を行い不用な汚染染料を除去した場合、洗濯堅牢度が大きく向上する。従って、本発明は、画期的で、実用的価値が大きいものである。

[0001]
  The present invention relates to a dyeing system and a dyeing method based on the system that can dye a composite material or the like composed of almost all fibers in a single-bath system in the same color system, with robustness and high quality, and excellent in economic efficiency.
[0002]
  More specifically, the present invention classifies reactive dyes that are covalently bonded to fibers based on the difficulty of dyeing with polyamide fiber reactive dyes, dyeing conditions, and the like. In combination with a dye appropriately selected from acid-containing metal dyes, cationic dyes and disperse dyes, a single fiber material that can be covalently bonded to a reactive dye or a composite material consisting of almost all fibers, in a one-bath system, The present invention relates to a novel dyeing system capable of dyeing the same color system firmly and with high quality and excellent in economic efficiency, and a dyeing method based on the system.
[Background]
[0003]
  In recent years, composite materials composed of multiple fibers have been used for health clothing, functional clothing, water absorption, quick-drying, and cool clothing. The textile dyeing industry is seeking to improve competitiveness through high-quality, high-performance processing of multi-fiber composite materials. In particular, commercialization of functional clothing made of synthetic polyamide fibers and cellulose fibers is a major issue.
  Processing of composite materials composed of multiple fibers is complicated and difficult. In dyeing factories, a method of dyeing this composite material with a one-bath or one-bath two-stage dyeing method using reactive dyes, acid dyes, direct dyes, etc. was studied. Dyeings could not be obtained and only those that could not withstand household washing were obtained.
[0004]
  For this reason, the dyeing factory first dyes the cotton side with reactive dyes, performs post-treatment such as soaping, and then dyes the polyamide side with acid dyes and acid mordant dyes in an acid bath. This dyeing had to be carried out in a two-stage manner. However, this method requires a long time and many operations and is not economical. Moreover, even by dyeing by this two-bath two-stage method, the wet fastness of the dyed product is insufficient, and there is a limit to commercialization.
  The present inventors have previously proposed a robust method for dyeing polyamide-based materials with reactive dyes (Japanese Patent Laid-Open No. 7-97777). This method is characterized by dyeing in an acidic bath or a neutral bath containing a large amount of sodium sulfate, and by this method, a polyamide-based material is dyed with a reactive dye capable of covalently bonding to cellulose fibers. Made possible.
[0005]
  Further, the present inventors have carried out exhaust dyeing of a single material of synthetic polyamide, wool, silk and cellulose fibers and a composite material of synthetic polyamide, wool, silk, cellulose and other fibers using reactive dyes. Based on the effect of dye bath pH when dyeing 6-nylon, reactive dyes are classified into acidic reactive dyes and neutral reactive dyes, and both are used in combination to obtain the same color. (Japanese Patent Application No. 2000-388497).
However, since then, there has been a strong demand for dyeing composite materials containing synthetic polyamides that are difficult to dye, and synthetic polyamides that are more easily dyed than cotton, such as sweat-absorbing synthetic polyamides. It turns out that it is difficult to deal with everything with dye alone.
[0006]
  Furthermore, a very low material with a synthetic polyamide ratio of 15% or less, and a dyeing concentration of 0.5 o.m. w. In the case of an extremely light color of f (% by weight with respect to the weight of the object to be dyed) or less, even when the synthetic polyamide side is dyed deeply and a hue of the same color system is obtained, it has been found that the surface of the composite material is not uniform. In addition, a number of composite materials such as polyester fibers, especially composite materials with polytrimethylene terephthalate (PTT) and composite materials with polyacrylic fibers, have been experimentally developed and studied. There is also a craving for a robust dyeing method using a two-stage bath.
  Therefore, there has been a demand for a rational dyeing method that achieves robust and high-quality dyeing for any complex composite material and is economical.
[0007]
  In view of the above circumstances, the present inventors have intensively studied and studied in order to develop a method capable of excellent dyeing even for many composite materials that are difficult to dye. As a result, reactive dyes are classified according to the difference in dyeability between cellulose fibers and synthetic polyamide fibers, and based on this classification, one or more reactive dyes or combinations thereof that are suitable for the material to be dyed are selected. By combining the reactive dye with other dyes such as acid metal-containing dyes, cationic dyes or disperse dyes, all the dyes used can be dyed by adjusting them in one bath. As a result, the inventors have found a dyeing system capable of industrially advantageously obtaining a dyeing product having the same color, robustness and high quality, and completed the present invention.
DISCLOSURE OF THE INVENTION
[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
[0038]
  Hereinafter, the present invention will be described in more detail.
  The present inventor systematically classifies reactive dyes by analyzing the dyeing behavior in the same bath of both fibers, the problem caused by the difference in dyeing properties of reactive dyes for synthetic polyamide fibers and cellulose fibers in composite materials, It was assumed that this could be solved by appropriate selection of dyes based on the classification.
  Then, it was found that the analysis of the dyeing behavior of both fibers in the same bath and the systematic classification of reactive dyes can be determined promptly and appropriately by the beaker scale test dyeing of the supplied dyestuffs. The above classification was developed as a systematic classification, and the above classification method was found. More specifically, the above systematic classification of reactive dyes and the reactive dye classification method of the present invention can be performed, for example, by the following method.
[0039]
  Commercially refined 6-nylon jersey (* 70d, 24F, twin yarn) 5g and commercially refined unsilted cotton knit (* 40d, single yarn) 5g together, 100ml hot water at 93-97 ° C Immerse it for 5 minutes and add 500 ml of ion-converted water. This is dehydrated with a household centrifugal dehydrator for 5 minutes, and then the weight of both is weighed.
  The weight is about 6.93 ± 0.14 g of 6-nylon jersey and 8.9 ± 0.31 g of cotton knit.
[0040]
  The dehydrated both are dyed in a 200 ml dye bath with a normal pressure rotating dyeing machine. The dyeing concentration was adjusted to 2.0% o. w. f, (% by weight of the dye based on the weight of the fabric) (however, in the case of the Navy dye, 5.0% owf, in the case of the Black dye, 10.0% owf), and 40 g of anhydrous sodium sulfate / L, (60 g / l for Navy dye, 80 g / l for Black dye), dyed for 40 minutes at 100 ° C., cooled to 70 ° C., added 20 g / l sodium carbonate, and added 40 Stain for minutes. Then drained, washed with water, washed with hot water at 80 ° C. for 3 minutes, soaped with polycarboxylic acid based soap 2 g / l, bath ratio 1:40, at 95-100 ° C. for 5 minutes, washed with water and dried. And finish. The obtained both dyeings are measured with the SICOMUC-20 system (manufactured by Sumika Chemical Analysis Center) to obtain the color density ratio of the 6-nylon jersey dyeing to the cotton dyeing and the corrected color difference. The reactive dyes are classified as described above based on the density ratio and the corrected color difference.
[0041]
  In this reactive dye class, reactive dyes belonging to Class A are dyes that are clearly dyed with synthetic polyamide fibers, which are solid materials of hard-dyeing synthetic polyamide fibers and cellulose fibers or easy-dyeing synthetic polyamide fibers. It is advantageously applied to dyeing. Here, the hardly dyeable synthetic polyamide fiber refers to a synthetic polyamide fiber having a water absorption of less than about 10%, particularly a fiber having a water absorption of about 8% or less, and a water absorption of 6,6. -Nylon, dense 6-nylon, etc. are exemplified.
[0042]
  Reactive dyes belonging to class C are dyes that are dyed deeply on the cotton side.
A composite material of easily dyeable synthetic or natural polyamide fiber and cellulose fiber,
0.5% o. w. The present invention can be advantageously applied to a light-colored field of f or less or a composite material having a synthetic polyamide fiber content of 15% or less.
Here, the easily dyeable synthetic polyamide refers to a synthetic polyamide fiber having a water absorption of about 10% or more, and examples include a sweat-absorbing synthetic polyamide. As a composite material of an easily dyeable synthetic polyamide fiber and cellulose fiber, The reversible material which consists of this synthetic polyamide and cotton is illustrated.
[0043]
  In addition, dyeing of cotton alone with commercially available three primary color dyes, Navy dyes or Black dyes has not yielded dyes that have both good chlorine and light fastness. Thus, the fastness of chlorine (effective chlorine 20 ppm) can be greatly improved by at least the first grade or more. Moreover, sweat light resistance can also be improved. The same applies to the case of the above-mentioned polyamide fiber (excellent fastness is obtained), but the present invention exhibits the above-described excellent effects even in a single material such as polyamide fiber or cellulose fiber.
[0044]
  Dyes belonging to SNCs are dyes in which both synthetic polyamide fibers and cellulose fibers are dyed approximately equally, and are suitable for dyeing both sides equally with the same color. It can also be used as a hue adjusting dye.
  The dyes belonging to SNs are dyed particularly deeply in the synthetic polyamide, and the cellulose fiber side is only slightly dyed, so that it is necessary to adjust the hue and density only on the synthetic polyamide side.
  The dyes belonging to the SCs are dyed extremely deep on the cellulose fiber side, and the synthetic polyamide is hardly dyed, and is a valuable dye for adjusting the hue and density on the cellulose fiber side.
[0045]
  The design of what kind of dye combination is used is very important for whether or not a wide variety of composite materials can be dyed in the same color, but according to the above classification and use that can be obtained by trial dyeing, the appropriate species A genus dye can be selected and an appropriate dyeing recipe can be readily determined.
  Until now, since there was no such dye selection method, it was impossible to make a reliable dyeing prescription for obtaining the same color, and there were many troubles, and it was thought that the two-bath two-stage method had to be carried out.
[0046]
  In the present invention, the reactive dye selected as described above can be used in combination with other dyes such as acidic metal-containing dyes, and the advantageous effects described below can be obtained.
[0047]
  For example, polyamide fiber, composite material of polyamide fiber and cellulose fiber, etc. in combination with dye belonging to class A and appropriately selected acidic metal-containing dye, dyes belonging to class C, SN, SC The one-bath dyeing at a low temperature of about 60 to 90 ° C. becomes possible. For example, examples of very difficult dyeings include composite materials made of synthetic polyamide, which are hardly dyed with reactive dyes, such as shape-up pants, and these can be suitably dyed by this combination. .
[0048]
  The selected acid metal-containing dye is dyed in a dye bath containing a considerable amount of sodium sulfate, so that it has good solubility, less cotton contamination, and important performance is 10 g of sodium carbonate, which is a dyeing condition on the cotton side. / L, 70 ° C., 30 minutes at 30 minutes, the acidic metal-containing dyes dyed on the polyamide fibers are not desorbed, and those that are not more than about 10% are preferred. For solubility, a solubility of 5 g / L or more at 25 ° C. or 50 g / L or more at 80 ° C. is required.
  The mixing or combination of the selected acidic metal-containing dye and reactive dye can be arbitrarily determined depending on the dyeability of the fiber material.However, since the three primary color dyes with similar dyeing speeds cannot be combined with the acidic metal-containing dye, a single dye or hue The combination of the two primary color dyes of the above and the three primary colors of the reactive dye is advantageous.
[0049]
  In particular, a mixture of the acid metal-containing dyes, such as clear yellow dye, blue dye and relatively bright red dye, and reactive dyes yellow dye, blue dye and red dye belonging to class A, has a concentration of 6-nylon dyeing. And the effect of improving the sharpness. It is also effective in improving leveling and wet fastness in wool dyeing.
[0050]
  The present invention can also be applied to a dyeing process in one bath of a three-component composite material including a polyacrylic fiber or a polyester fiber, particularly a synthetic polyamide fiber and cellulose fiber. The polyester fiber includes polytrimethylene terephthalate fiber that has been recently developed.
  It is necessary to dye these polyacrylic fibers and polyester fibers with a cationic dye or a disperse dye in an acidic bath. Therefore, an acidic bath is necessary even when dyeing in one bath in combination with a reactive dye.
  Therefore, it is necessary to select an appropriate reactive dye based on the classification based on the dyeability with acid addition. The HPs and HQs in the reactive dye classification correspond to this classification.
  That is, according to the classification method of reactive dyes, the weight ratio of 6-nylon jersey (manufactured by Toray Industries Inc.) 50% and cotton knit (non-silquette) 50% is 1% o. w. Dyeing in a dye bath with f added, and the resulting dyed product is side-colored with a SICOMUC-20 system (manufactured by Sumika Chemical Analysis Center Co., Ltd.). They are classified based on the color difference.
[0051]
  The dyes belonging to HPs and HQs are particularly suitable for the method of dyeing composite materials such as polyacrylic fibers and polyester fibers and cellulose fibers in the same color in a single bath in combination with cationic dyes or disperse dyes dispersed in a dye bath. Suitable. Preferred dyes as HQs are those having the concentration ratio in the range of 55 to 95%.
  Here, the polyamide fiber is a dye that dyes HPs darkly and HQs lightly.
  It is preferable to use a dye that dyes the polyamide side lightly in actual dyeing because there are many reactive dyes that dye the nylon side darkly when acid is added, and in combination with disperse dyes, the disperse dye also partially dyes on the polyamide side. There are many cases.
The cationic dye used here is preferably a dispersed cationic dye that does not cause aggregation of the dye. Moreover, the reactive dye selected from the said A class and C class etc. can be used together as needed.
[0052]
  Disperse dyes for dyeing polyester fibers are particularly preferably disperse dyes that have high dye transfer properties and do not remain on cellulose fibers, and disperse dyes that have good light fastness even when partially dyed on synthetic polyamide fibers. Although the dye adjusted to one bath of the present invention is used as a single dye or a mixed dye, the predetermined mixing ratio can also be adjusted with a dye bath.
[0053]
  The fastness of dyeings is important in commercialization and requires at least wet fastness that can withstand household washing. In particular, it is important for new products to withstand 30 washings.
  As described above, the order of the dyeing process has an important influence on the wet fastness, and it is effective to dye the synthetic polyamide fiber first and finally the cellulose fiber such as cotton.
  That is, the dyeing of cotton is treated with an alkali bath such as sodium carbonate, which has the effect of removing the dye that swells cotton and contaminates the cotton or the undyed dye on the surface of the synthetic fiber. Subsequent water washing, hot water washing, and soaping processes improve fastness. In other words, this process has two roles of fixing by cotton-dye chemical bond and removing unwanted dye. On the contrary, since this effect cannot be obtained if cotton dyeing is started, even in the case where this order is unavoidable, a bath composed of sodium carbonate 2 to 10 g / L and anhydrous sodium sulfate 20 to 100 g / L. It is preferable to perform alkali treatment at 60 to 70 ° C. for about 5 to 30 minutes.
[Industrial applicability]
[0054]
  With the dyeing system and dyeing method of the present invention, it is possible to dye a composite material composed of almost all the fibers, and in particular, sufficient dyeing can be achieved even in the case of two times (two bath method) and three times (three bath method). Even complex and difficult dyeing that cannot be obtained can be dyed with high quality and high fastness by one time (one bath system).
  Because it is possible to dye in one bath, dyeing wastewater is reduced, energy saving, and labor saving compared to the conventional two-bath two-stage dyeing method, and at least about 30% compared to standard dyeing at the factory scale. Cost reduction and about 40% of time reduction are possible, and the economic effect is not measurable.
  Moreover, the fastnesses of the dyed product according to the present invention of the one-bath system are extremely excellent. That is, in the two-bath system, the polyamide fiber and the acid dye are ion-bonded, whereas in the one-bath system of the present invention, the reactive dye is chemically bonded (covalently bonded) to the amino fiber of the polyamide fiber. Contributes to improved fastness. In particular, when an alkali treatment is performed at the end of the dyeing process to remove unnecessary staining dyes, the fastness to washing is greatly improved. Therefore, the present invention is innovative and has great practical value.
