【発明の属する技術分野】
本発明は、耐久性のある繊細なシワやプリーツを有する布帛や縫製繊維製品の製造法に関するものであり、さらに詳しくは、風合に優れ、吸水性等のセルロース系繊維の特性を低下させることが少なく、耐久性で意匠性に富んだシワを有するセルロース系繊維含有繊維製品の製造方法に関するものである。
【０００２】
【従来の技術】
綿、レーヨン、麻などのセルロース系繊維単独あるいはこれらのセルロース系繊維を含有する布帛に、耐久性のあるシワを付与する試みがなされているが、合成繊維の場合のような熱セット性が少ないため、洗濯や着用後のシワ形状の保持性が極めて悪く、問題となっている。
【０００３】
また、布帛にセルロース架橋能のあるグリオキザール系の樹脂と触媒を付与後、布帛状態でシワを付与後、縫製し、次いでベーキングしてグリオキザール系樹脂の樹脂化を起こさせてシワ形状を固定化する方法や前記の樹脂と触媒を付与した布帛を縫製後、該縫製品にシワを付与し、次いでベーキングして樹脂化を起こさせてシワ形状を固定化する方法もとられてきた。しかしながら、前記方法によりシワの耐久性は向上するものの、繊細でシャープなシワ形状の再現が難しく、又風合が硬い、吸水性が劣る等の致命的な欠点があった。
【０００４】
【発明が解決しようとする課題】
本発明は、繊細でシャープなシワやプリーツを有し、かつ風合がソフトで吸水性にも優れた耐久性のあるシワまたはプリーツを有するセルロース系繊維含有布帛及び縫製品を提供しようとするものである。
【０００５】
【課題を解決するための手段】
即ち、本発明は、液体アンモニアでセルロース系繊維を前処理後、シワまたはプリーツ付け処理をした後、さらに高圧処理又は減圧処理をすることを特徴とする耐久性のシワまたはプリーツ加工方法である。
【０００６】
【発明の実施の形態】
本発明で言うセルロース系繊維とは、木綿、麻等の天然繊維、ビスコースレーヨン、ポリノジック等の再生セルロース系繊維を意味する。
これらセルロース系繊維は単独での使用のみならず、ポリエステル繊維、ポリアミド繊維、ポリアクリロニトリル繊維等の合成繊維と混用することができる。合成繊維の含有率が５０重量％以下の時に本発明の特徴が効果的に発揮される。
【０００７】
本発明で言う布帛とは、織物、編織物、不織布等を意味する。
本発明で言うセルロース系繊維の膨潤剤とは、セルロース系繊維を膨潤させたり、溶解する能力を有するものであり、硫酸、燐酸、塩化亜鉛、水酸化ナトリウムや水酸化カリウム等の金属水酸化物、ロダン塩等の無機塩、銅エチレンジアミン等のアミン、液体アンモニア等を挙げることができる。これらの中で水酸化ナトリウム、液体アンモニアが簡便で好ましく、特に液体アンモニアは繊維でシャープなシワやプリーツを付けることが容易であり、好ましい。
【０００８】
前記膨潤剤によるセルロース系繊維含有布帛の前処理方法は、特に限定されないが、膨潤剤を含有する水溶液中に布帛を適度の膨潤が発生するように浸漬あるいは通過させる方法がとられる。
膨潤させられたセルロース系繊維の断面は、短軸、長軸の比が１に近く、円形に近いものが好ましい。例えば木綿繊維の場合、木綿単繊維の平均の短軸／長軸比が０．６以上、好ましくは０．７以上に膨潤させることが好ましい。
【０００９】
本発明におけるシワとは、布帛に起状、凹凸、ふくらみ感等を与える布帛の折れジワ、縮み等を意味し、微細で繊細なものが好ましい。
本発明におけるプリーツとは意匠性を高めることを目的に付与されるプリーツであり、規則性のあるもの、幾何学的な模様など、特に限定されない。
【００１０】
本発明におけるシワやプリーツ付け処理方法としては、シワやプリーツを付けることが可能なものであればどんな装置でもよいが、ミリング機、リラクサー、液流染色機、タンブルドライヤーロープ洗浄機、ロープ走行風合加工機や袋つめ法や周期的に連続線状プリーツを施す方法等、特に限定されないが、繊細なシワを付与することができるミリング機によるシワ付け処理が好ましい。処理の条件も目的とするシワの形状にもよるが、通常、常温で３０分間程度の処理が行なわれる。プリーツ付け処理方法としては、加熱圧縮プレス法など公知の方法を採用することができる。
【００１１】
前記のシワまたはプリーツ付け処理した布帛は、そのままでも使用できるが、さらにシワまたはプリーツの耐久性を向上させるために、種々の処理機械により、種々の処理を施すことができる。
例えばプレス処理、高圧処理、減圧処理、樹脂加工処理、ホルマリンガス等による気相処理、水蒸気処理などが挙げられる。
これらの処理の中で風合を損なわない点で減圧処理、水蒸気処理が好ましく、より耐久性で、かつ風合の変化が少ない点で減圧処理、さらにはホルマリンガスによる気相処理が好ましい。
【００１２】
減圧処理は、減圧釜等、減圧状態にできる装置を用い、−５００〜−２０００ｍｍＨｇ（その系における最大蒸気圧に対して）、１０〜１３０℃、２〜１２０分程度の条件で処理することが好ましい。
【００１３】
本発明におけるセルロースの架橋剤とは、気体、液体、固体、水溶液のいづれでもよいが加熱で容易に蒸気となって、セルロース繊維内部へ浸透できるものであり、パラホルムアルデヒド、ホルマリン水溶液等でホルムアルデヒド蒸気を発生するものが好ましい。
【００１４】
ホルムアルデヒド蒸気の場合、潜在性酸性触媒を予め、セルロース繊維含有織編物に均一に付与することにより、二酸化硫黄ガスを使用することなくホルムアルデヒドがセルロース中に存在するＯＨ基と反応し、セルロース分子鎖間の架橋が生成する。
【００１５】
本発明で使用できる潜在性酸性触媒には、その代表例を例示すると、ＮＨ４ Ｃ１、ＮＨ４ Ｂｒ、（ＮＨ４ ）２ ＨＰＯ４ 、ＮＨ４ Ｈ２ ＰＯ４ （ＮＨ４ ）２ ＳＯ４ 、ＮＨ４ ＮＯ３ などの無機強酸のアンモニウム塩類、ギ類アンモン、酢酸アンモン、シュウ酸アンモンなどの有機酸のアンモニウム塩類、ＺｎＣｌ２ 、Ｚｎ（ＮＯ３ ）２ 、Ｚｎ（ＢＦ４ ）２ 、ＭｇＨＰＯ４ 、ＡｌＣｌ３ 、Ａｌ（ＮＯ３ ）３ 、Ａｌ２ （ＳＯ４ ）３ 、ＣａＣｌ２ などの金属の強酸塩類、２−アミノ−２−メチル・プロパノール塩酸塩などのアルカノールアミンの塩酸塩類、及びこれらの混合触媒系などが挙げられる。
【００１６】
これら触媒系にＨ２ ＳＯ４ 、ＨＮＯ３ 、ＨＣｌ、ギ酸、シュウ酸などの強酸を使用してもさしつかえない。
好ましくは、無機強酸のアンモニウム塩類、金属の強酸塩類、アルカノールアミン塩類が挙げられる。
【００１７】
本発明において、セルロース系繊維は、ホルムアルデヒド等の蒸気に接触させる前に、前記のセルロースの膨潤剤が少なくとも１度、セルロース繊維内部に、しかもできるだけ均一に浸透させられると、ホルムアルデヒド等の蒸気は容易にセルロース繊維内部にまで、しかも均一に浸透させることができる。
また、より効率的に浸透させるために、−５００ｍｍＨｇ以下の減圧系で減圧処理することが有効である。
したがって、セルロース繊維中に、局部的な架橋を形成せしめたり、歪をもたらすような架橋を避けることができ、セルロース繊維の強力低下を防止することができる。
【００１８】
本発明において、セルロース系繊維が前記の膨潤剤で繊維の断面の短軸／長軸比が０．６以上に膨潤され、次いで布帛状態で前記のシワ付け処理され、該シワ付け処理された布帛を用いて縫製品とし、該縫製品を前記のセルロース架橋剤で気相で処理することにより、縫製品が持っているシワを変形させたり、消失させることなく、安定に固定することができる。
【００１９】
したがって、本発明の方法によって得られた縫製品は、シワ付け処理工程で付与された繊細な意匠性に富んだシワをそのまま保有し、ソフトな風合で吸水性があり、かつ繰返し洗濯によってもそのシワを保持する特徴を有するのみならず、特性の変化が少なく生地の強力低下が少ないことも特徴である。
【００２０】
なお、本発明で言う縫製品とはミシン糸あるいは接着剤等で縫製されるものであり、シャツ、ブラウス等の衣服やスカーフ、ハンカチ等の人が身に付けるもの、シーツ、カバー等を挙げることができる。
