Description

【発明の属する技術分野】
シャツ、スラックス、ブラウス等の衣料用及び帽子、ハンカチ等繊維雑貨品として、好適なセルロース系繊維含有繊維製品に関するものであり、さらに詳しくは、製品の強力低下をおさえ、しかも防縮性、W&W(ウォッシュアンドウェア)性、プリーツ性及びパッカリング性、保型性を向上させた木綿繊維含有繊維製品に関するものである。
【0002】
【従来の技術】
セルロース系繊維のしわになり易い、収縮し易い等の欠点の改善は、永久的課題であり、縫製品においては、特に従来よりセルロース系繊維含有繊維製品のくり返し洗濯による生地と縫い糸又は生地部位間の伸縮性の差により生ずるパッカリング現象(ひきつれ現象)や製品形状での保型性の改善が強く望まれている。この問題点を改善しようとして、製品状態でのホルマリンによる気相反応を利用する試みがあるが、セルロース繊維が著しい強力低下をきたすという、新たな問題がクローズアップされ、解決が望まれている。
【0003】
【発明が解決しようとする課題】
本発明は良好な風合いを有し、防しわ性に優れ、かつ繰り返し洗濯後のパッカリング性、W&W性、防縮性、保型性に優れ、同時に気相ホルマリン処理による強力低下を極力おさえた木綿繊維含有繊維製品及び工業生産性に優れた製造方法を提供しようとするものである。
【0004】
【課題を解決するための手段】
本発明者らは、木綿繊維を膨潤剤で膨潤させ、木綿繊維の歪みを緩和しておくことが、架橋改質後の木綿繊維製品の強力低下を抑えることに有効であることを見出した。
【0005】
即ち、本発明は、架橋長制御剤として、下記の化3又は化4の化合物が付与され、木綿繊維中の結合ホルマリン量が0.6重量%以上である木綿繊維を含有する木綿繊維含有繊維製品。
【0006】

0Hであり、R1 、R2 、R3 、R4 、R5 およびR6は同種または異なる基であり、それぞれH、OH、COOR、R、ORまたはCOORのいずれかの基であり、Rは炭素数1〜4のアルキル基または置換アルキル基のいずれかを表し、XはC、OまたはNで、XがOの場合、R3 とR4 は各々存在せず、XがNの場合、R3 あるいはR4 が存在しない。さらに木綿繊維の膨潤剤で前処理され、さらに前記の架橋長制御剤が付与された木綿繊維含有織編物又は不織布を縫製し、次いでセルロース分子間架橋可能な化合物を該縫製品に付与せしめた後、木綿繊維内部で架橋させることを特徴とする前記の木綿繊維含有繊維製品の製造方法である。
【0009】
ホルムアルデヒド単独によるセルロースの架橋の場合、架橋長が短く、架橋歪が残留し、結果として改質に伴なう強力低下が著しい欠点があったが、本発明における架橋長制御剤(以下、メチロール化可能な活性水素を有する化合物ということある)は、織編物等の布帛の架橋歪を低減させるためのものであり、この効果はホルムアルデヒドによるセルロース間の架橋に加え、該化合物がメチロール化された後セルロースと架橋する、いわゆる架橋長制御により発揮されるものである。このことにより、製品の洗濯後のパッカリング性、保型性等、製品の形態安定性が向上すると同時に引裂強力、抗張力が著しく改善される。さらに、前処理織編物の貯蔵安定性に加え、ホルマリン臭の低減にも有効である。
【0010】
上述の如く、予め膨潤前処理による木綿繊維の歪み緩和を計った上での架橋長制御剤に付与によるホルマリン架橋時の架橋歪みの軽減はW&W性と同時に木綿繊維の力学的特性改善に有効である。
【0011】
好適な実施態様としては、架橋改質する改質法が気相ホルマリン加工法であり、また、架橋改質した繊維製品においてその構成する木綿繊維の結合ホルマリン量が0.6重量%以上である。
【0012】

【0016】
液体アンモニア処理はドライプロセス(P.H.Greenwood;J.S.D.C.,103 342(1987)やウエットプロセス(K.Bredereck,A.Bluher; Mell. Textilber.,72,446(1991)いずれの方法でも利用できる。また、上述の液体アンモニア処理した後、熱水によるリラックス処理を施してもかまわない。液体アンモニアにより処理する場合、木綿繊維含有織物などの繊維構造物は液体アンモニアに2〜20秒間浸漬後、5〜90秒、望ましくは5〜20秒のタイミングを置いて乾熱、蒸気および水洗によって脱アンモニア処理される。
【0017】

【0022】
前記の化5および化6の化合物の内、好ましいメチロール化可能な活性水素を有する化合物としては、ジヒドロキシエチレン尿素などのジヒドロキシエチレン尿素類が挙げられる。染色物の耐光性などからジヒドロキシエチレン尿素類が好ましい。これら架橋長制御剤の使用量はセルロースおよび木綿含有繊維構造物に対して、0.5〜20重量%である。風合いなどを考慮すると更に好ましくは、1〜5重量%である。
【0023】
本発明で使用できる柔軟剤類としては次のようなものが挙げられる。即ち、ジメチルポリシロキサン、エポキシ変性シリコーン、アミノ変性シリコーン、水溶性シリコーンなどのシリコーン類、ポリエチレンエマルジョン類、脂肪族酸アミド類、ポリウレタン樹脂類、ポリエステル樹脂類、アクリル酸エステル類、ワックス類、ノニオン、アニオン、カチオン、両性の界面活性剤類などが挙げられる。特に、ポリエチレンエマルジョン類、シリコーン類などが風合い向上、引裂強力向上に有効である。
【0024】
本発明で使用できる潜在性酸性触媒としては、AlCl 、Al (SO 、MgCl 、Mg(H PO 、Zn(BF 、Zn(NO、ZnCl 、Mg(BF 、Mg(ClO 、Al (OH) Cl などの各種金属塩(結晶水含有も含む)類、2−アミノ−2−メチル−1−プロパノールの塩酸塩などの各種アルカノールアミンの酸性塩、硝酸、塩酸、硫酸、りん酸など強酸のアンモニウム塩、蓚酸、クエン酸などの有機カルボン酸などがある。これら潜在性酸性触媒の使用量は0.1〜5重量%である。ホルムアルデヒド蒸気の処理後のキュア条件は、触媒の共存下、通常、20〜160℃で1〜60分間である。
【0025】
本発明において架橋反応の程度は、結合ホルマリン量で示されるが、必要であれば結合窒素含有量も合せて示すことができる。本発明の目的を達成するための木綿中の結合ホルマリン量は0.6重量%以上必要である。好ましくは0.8重量%以上である。結合ホルマリン量が0.6重量%未満の場合、十分な改質効果が得られない。即ちパッカリング性、W&W性、保型性、プリーツ性が不十分である。
【0026】
上記ホルマリン加工により、防しわ性に優れ、かつ繰り返し洗濯後のパッカリング性、W&W性、防縮性、保型性に優れ、同時に加工による強力低下、特に引裂強力低下を極力抑えた木綿繊維含有繊維製品が製造可能となる。
【0027】
本発明の木綿繊維含有繊維製品は、織物の場合、JIS L−1059B法(モンサント法)における乾防しわ度が270度以上であり、湿防しわ度との合計値は550度以上が好ましく、570度以上がより好ましい。特に乾防しわ度と湿防しわ度との合計値が高い程、W&W性が高くなり、パッカリング性及び保型性にも優れる。これらの防しわ性を達成できるように改質された木綿繊維が含まれる縫製品は、AATCC124−1984法におけるW&W性が3級以上かJIS L−0217の103法による洗濯5回後のAATCC法におけるパッカリング性が4級以上の保型性を示す。
【0028】
本発明におけるセルロースを架橋させることができる薬剤とは、気体、液体、固体、水溶液のいずれでもよいが、加熱等で容易に蒸気となって、木綿繊維内部へ浸透できるものであり、ホルムアルデヒドが好ましい。
【0029】
セルロースとホルマリンの架橋反応を円滑に進めるためには、木綿繊維中へいかにホルマリンを吸着させるかにつきる。これにはホルマリン気相加工前の縫製品を予め調湿処理することが望ましい。この際の生地水分率は5〜15重量%が好ましく、より好ましくは6〜10重量%である。ホルムアルデヒド蒸気の処理条件は、触媒の共存下、通常、80〜160℃で1〜60分間である。
【0030】
気相ホルムアルデヒド処理は、布帛の状態及び縫製品の状態のいずれでも処理できるが、縫製品にした後に処理する方が、縫製上の問題発生がなく、縫製品の形状をも効果的に固定するので、パッカリング性、保型性が著しく高くなり、好ましい実施態様である。

In sewn products, especially between fabrics and sewing threads or fabric parts by repeated washing of cellulosic fiber-containing fiber products. There is a strong demand for improvement in the puckering phenomenon (strain phenomenon) caused by the difference in stretchability and the shape retention in the product shape. In order to improve this problem, there is an attempt to use a gas phase reaction with formalin in a product state. However, a new problem that cellulose fiber is significantly reduced in strength is highlighted and a solution is desired.

In the case of cross-linking of cellulose with formaldehyde alone, the cross-linking length is short and the cross-linking strain remains, resulting in a significant disadvantage that the strength decrease accompanying modification is significant, but the cross-linking length control agent in the present invention (hereinafter referred to as methylolization). This compound is sometimes used to reduce the cross-linking distortion of fabrics such as woven and knitted fabrics. This effect is not only in the cross-linking between cellulose by formaldehyde but also after the compound is methylolated. It is exhibited by so-called crosslink length control that crosslinks with cellulose. This improves the form stability of the product such as puckering and shape retention after washing the product, and at the same time significantly improves the tear strength and tensile strength. Furthermore, in addition to the storage stability of the pretreated woven or knitted fabric, it is also effective in reducing the formalin odor.

As the latent acidic catalyst that can be used in the present invention, AlCl 3 , Al 2 (SO 4 ) 3 , MgCl 2 , Mg (H 2 PO 4 ) 2 , Zn (BF 4 ) 2 , Zn (NO 3 ) 2 , ZnCl 2 , Mg (BF 4 ) 2 , Mg (ClO 4 ) 2 , Al 2 (OH) 4 Cl 2 and other metal salts (including crystal water), 2-amino-2-methyl-1-propanol There are acid salts of various alkanolamines such as hydrochlorides, ammonium salts of strong acids such as nitric acid, hydrochloric acid, sulfuric acid and phosphoric acid, and organic carboxylic acids such as oxalic acid and citric acid. The amount of these latent acidic catalysts used is 0.1 to 5% by weight. Cure conditions after the treatment with formaldehyde vapor are usually 20 to 160 ° C. for 1 to 60 minutes in the presence of the catalyst.
[0025]
In the present invention, the degree of the crosslinking reaction is indicated by the amount of bound formalin, but if necessary, the bound nitrogen content can also be indicated. In order to achieve the object of the present invention, the amount of bound formalin in cotton needs to be 0.6% by weight or more. Preferably it is 0.8 weight% or more. When the amount of bound formalin is less than 0.6% by weight, a sufficient reforming effect cannot be obtained. That is, puckering property, W & W property, shape retention property, and pleat property are insufficient.
[0026]
The above-mentioned formalin processing is excellent in wrinkle resistance, and has excellent puckering after repeated washing, W & W properties, shrinkage resistance, and shape retention, and at the same time, a fiber containing cotton fibers that suppresses the decrease in strength due to processing, especially tear strength. The product can be manufactured.
[0027]
In the case of textile, the cotton fiber-containing fiber product of the present invention has a dry wrinkle degree of 270 degrees or more in the JIS L-1059B method (Monsanto method), and the total value of the moisture prevention wrinkle degree is preferably 550 degrees or more, 570 degree | times or more are more preferable. In particular, the higher the total value of the dry proof wrinkle degree and the wet proof wrinkle degree, the higher the W & W property and the better the puckering property and the shape retention property. Sewing products containing cotton fibers modified so as to achieve these wrinkle-proofing properties have a W & W property of grade 3 or higher in the AATCC 124-1984 method or the AATCC method after 5 washes according to the 103 method of JIS L-0217 The puckering property at 4 indicates a shape retention property of grade 4 or higher.
[0028]
The agent capable of cross-linking cellulose in the present invention may be any of gas, liquid, solid, and aqueous solution, but is easily vaporized by heating or the like and can penetrate into cotton fibers, and formaldehyde is preferable. .
[0029]
In order to facilitate the cross-linking reaction between cellulose and formalin, it depends on how formalin is adsorbed into cotton fibers. For this purpose, it is desirable to preliminarily humidity-treat the sewing product before formalin gas phase processing. In this case, the moisture content of the dough is preferably 5 to 15% by weight, more preferably 6 to 10% by weight. The processing conditions for formaldehyde vapor are usually 80 to 160 ° C. for 1 to 60 minutes in the presence of the catalyst.
[0030]
Vapor-phase formaldehyde treatment can be performed in either fabric state or sewing product state, but processing after making it into a sewing product will not cause any problems in sewing and will effectively fix the shape of the sewing product. Therefore, the puckering property and the shape retaining property are remarkably enhanced, which is a preferred embodiment.
