【発明の詳細な説明】 布帛の処理 技術分野 本発明は、溶剤紡糸セルロース繊維であって、リヨセル繊維(lyocell fibre)で知られる繊維のフィブリル化の度合い及びフィブリル化の傾向 を低下させる方法に関する。 関係技術の説明 セルロース繊維がその適当な溶剤のセルロースの溶液を凝固浴中に押出すこと で得られることは知られている。押出と凝固とからなるこのプロセスは、溶剤紡 糸(solvent−spinning)といわれ、かくして得られるセルロー ス繊維は「溶剤紡糸されたた(solvent−spun)」セルロース繊維と いわれる。このような方法の一例は、米国特許第4,246,221号に記載さ れており、その記載内容をここに引用して本明細書の説明に含める。セルロース は、例えば第3アミン−N−オキシドのような溶剤に溶ける。この溶液は適当な ダイを通して押出されれてフィラメントになり、このフィラメントは凝固、水洗 されて溶剤が除去され、そして乾燥される。一般に、ある製造段階でこのフィラ メントは短い長さに切断されステープルファイバーになる。 セルロース繊維がセルロースの誘導体の溶液を再生浴及び凝固浴に押出すこと によって製造できることも知られている。このような方法の一例がビスコース法 である。ビスコース法では、セルロース誘導体がセルロースザンテートである。 かかる両方法のタイプは、湿式法の例である。溶剤紡糸法は、ビスコース法のよ うな公知のセ ルロース繊維の生産方法よりも、例えば環境放出が低減する等の幾多の利点をも っでいる。 ここで用いるターム、「リヨセル繊維(lyocell fibre)」とは 有機溶剤紡糸法により得られるセルロース繊維を意味し、有機溶剤紡糸法にあっ ては、溶剤が有機化学剤と水の混合物であるのが本質的で、溶剤紡糸はセルロー スの誘導体の形成なしに、セルロースを溶解すること及び紡糸するこよりなる。 ここで用いるターム「溶剤紡糸されたセルロース繊維」は、「リヨセル繊維(l yocell fibre)」)と同義語である。ここで用いるリヨセル布帛と は、少なくとも一部にリヨセル繊維を単独又はブレンドで含んでいる複数の糸か ら織られ又は編まれた布帛を意味する。 繊維は、特に湿潤状態で機械的なストレスを受けるときフィブリル化する傾向 を示す。フィブリル化は、繊維構造がその長手方向で壊れたときに細いフィブリ ルが繊維から部分的に離れて、繊維又はその繊維を含む例えば編織物を毛羽立っ た外観のものにする。フィブリル化した繊維を含んだ染色布帛は、白化(fro sted)外観を呈しがちで、美的観点上望ましくない。このようなフィブリル 化は、湿潤又は膨潤状態での加工処理の間に繊維の機械的な摩擦によって起るも のと考えられている。精錬、漂白、染色及び洗濯等の湿潤処理加工は、不可避的 に繊維に機械的摩擦を被らせる。高い温度での処理や長時間の処理程、より大き い程度のフィブリル化を発生させる一般的な傾向がある。リヨセル繊維布帛は、 このような摩擦に特に敏感にみえる。そして他の種類のセルロース繊維から造ら れる織物等の布帛よりもよりフィブリル化し易いことがしばしば指摘されている 。木綿繊維は、本来特に低いフィブリル化傾向をもつ繊維である。 EP−A−538,977は、フィブリル化したリヨセル繊維織 物から、セルラーゼの溶液で処理することによって、フィブリルが除去されるこ とを記載している。セルラーゼはセルロースの加水分解の触媒作用を有する酵素 である。しかし、このような処理はそれほど望ましい効果があるものではなく、 使用済の酵素の溶液の廃棄処理が環境問題を引き起こすこともあり得る。 セルロース布帛の耐皺性を改良するためにセルロース布帛を架橋処理剤で処理 することは、例えば、Wiley−InterscienceのKirk−Ot hmer’s Encyclopaedia of Chemical Tec hnology,third edition,volume 22(1983 )の769頁〜790頁の論文「繊維(仕上加工)」、及びH.Peterse nによるRev,Prog.Coloration,Vol.17(1987) 、7〜22頁の論文に記載されているように、多年にわたって知られてきたこと である。架橋剤は、ときには、例えば架橋性樹脂、化学仕上剤乃至樹脂仕上剤と いった別の呼び方をされることもある。架橋剤はセルロースの水酸基と反応して 架橋結合をつくることができる複数個の官能基を含む小分子物質である。常用タ イプの仕上加工では、セルロース布帛は、例えばパッド浴を適用するなどして先 づ架橋剤で処理され、乾燥され、そして加熱されて樹脂をキュアーして架橋化反 応がおこって加工される(パッド−ドライ−キュア法)。防皺加工はセルロース 布帛の摩擦抵抗性、引張り強度及び引き裂き強度を損なうことが知られている。 初期の架橋加工システムは、尿素−ホルムアルデヒド及びメラミン−ホルムア ルデヒド樹脂によるものであった。これら加工システムは多くの問題となる欠点 をもっていた。この処理方法は外部に付着する樹脂があるので布帛を一時的に硬 くさせていた。加工布帛は、貯蔵中に不快な臭気を発生しがちで、この異臭物質 は樹脂をキュ アするために用いられたアミン触媒と毒性の化学剤であるホルムアルデヒドを含 むことによるものであった。そこで、加工処理布帛を外部付着樹脂及び不快臭気 を発する樹脂形成副生成物を除去するために加工処理布帛を洗滌することが必要 であると考えられていた。処理布帛のこのような洗滌やその後の乾燥は、加工の コストにとって追加的な負担となる。 そこで、このような加工システムは、架橋剤として所謂「低−ホルムアルデヒ ド樹脂」及び「無−ホルムアルデヒド樹脂」を含むシステムでかなり置き換えら れてきている。このような処理剤の一つの既知例は、N−メチロール樹脂、つま り2個、又はそれ以上のN−ヒドロキシメチル又はN−アルコキシメチル、特に N−メトキシメチル基を含む小分子化合物からなる加工剤である。 N−メチロール樹脂は、一般に架橋化性能を改良するために選ばれた触媒と組 み合わせて用いられる。典型的な加工法では、N−メチロール樹脂架橋剤約5〜 9重量%及び酸触媒0.4〜3.5重量%を含む溶液を乾燥セルロース布帛にピ ック アップ60−100重量%でパッドし、その後この湿潤布帛を乾燥、次い で加熱してこの架橋剤をキュアーして固定する。低−ホルムアルデヒド樹脂又は 無−ホルムアルデヒド樹脂で加工処理された布帛は、一般に一時的な硬化現象を 起こさないし、又不快臭を放出しない。キュアーされた布帛生地及び加工衣類は 、消費者に販売する前にめったに洗滌されることはない。 発明の概要 本発明の第一の形態によるリヨセル布帛のフィブリル化傾向を低減する方法は 、次のステップ含む: (a)布帛を低ホルムアルデヒド又は無アルデヒド架橋性樹脂で 処理すること; (b)布帛を該樹脂とセルロースとの間で反応せしめるのに効果的な条件の下 で加熱すること; (c)該布帛を洗滌すること;及び (d)該布帛を乾燥すること。 本発明のこの形態及び他の形態では、布帛は平生地の形態で架橋性樹脂で処理 され、布帛生地の形態でセルロースと樹脂の間で反応させるべく加熱される。 本発明のこの形態及び他の形態の一つの具体的実施の形態で、好ましい形態で あるが、布帛は平生地の形態で洗滌されそして加熱され、その後衣類やその他の 繊維物品の生産のためのピースに裁断される。 本発明のこの形態及び他の形態の更に他の一つの具体的実施の形態では、布帛 を先づ衣装品に仕立てるか他の繊維物品に仕立てるかして、それから洗滌、乾燥 して本発明を完結させる。 本発明の第二の形態したがうリヨセル布帛のフィブリル化程度を低減する方法 は、次のステップを含む: (a)布帛を低ホルムアルデヒド又は無アルデヒド架橋性樹脂で処理すること ; (b)布帛を該樹脂とセルロースとの間で反応せしめるのに効果的な条件の下 で加熱すること; (c)該布帛を洗滌すること;及び (d)該布帛を乾燥すること。 本発明の第三の形態したがうリヨセル布帛のフィブリル化程度を低減する方法 は、次のステップを含む: (a)布帛を精錬そして染色して、それによって布帛にフィブリル化を誘発し : (b)該布帛を低ホルムアルデヒド又は無アルデヒド架橋性樹脂で処理するこ と; (c)該布帛を該樹脂とセルロースとの間で反応せしめるのに効果的な条件の 下で加熱すること; (d)該布帛を洗滌すること;及び (e)該布帛を乾燥すること。 本発明のこの第三の形態では、ステップ(a)の精錬と染色処理の間で任意的 に漂白してもよく又ステップ(a)とステップ(b)の間で乾燥することも任意 的である。ステップ(c)の後で、布帛はそれから造られた繊維物品が商業的に は到底受け入れられない程の高度のフィブリル化傾向を呈することがある。ステ ップ(e)の後、平生地状又は繊維物品状の布帛は、非常に低い商業的に望まれ る程度のフィブリル化度を呈する。 好ましい架橋性樹脂類は、N−メチロール樹脂である。適当なN−メチロール 樹脂の例は、前述したKirk−Othmerの論文及びPetersenによ る論文に記載されている。そのような樹脂は、例として1,3−ジメチロールエ チレン尿素(DEMU)、1,3−ジメチロールプロピレン尿素(DMPU)及 び4,5−ジヒドロキシ−1,3−ジメチロールエチレン尿素(DHDMEU) を含んでいる。他にウロン類、トリアジノン類及びカーバメート類系の化合物を 含む例がある。好ましい架橋剤の他の例は、1,3−ジアルキル−4,5−ジヒ ドロキシ(アルコキシ)エチレン尿素及びその誘導体の類をベースとする化合物 からなる。適当な架橋剤の更なる例にメラミンがある。適当な架橋剤の更なる例 にブタンテトラカルボン酸(BTCA)がある。一種以上のタイプの架橋化剤を 用いてもよい。 セルロース布帛の耐皺加工用の架橋剤は、一般に触媒が併用して 使用される。触媒は架橋化反応と樹脂キュアリング及び固定を促進する働きがあ る。本発明の方法は、好ましくは、使用のため選択された架橋剤と併用すること が勧められているときにはそのような触媒を利用するのが好ましい。例えば、N −メチロール樹脂は、好ましくは例えば酢酸のような有機酸又は硝酸亜鉛若しく は塩化マグネシウムのような金属の酸の触媒と組み合わせて用いられる。アンモ ニウム塩、アミン塩若しくは金属塩類のような潜在性の酸も用いることができる 。混合触媒システムも用いることができる。 架橋剤及び如何なる触媒は、好ましくは水の溶液から布帛に適用される。この 溶液は既知の方法、例えば溶液を布帛にパッドするとか、溶液の処理浴に布帛を 潜らせるなどして布帛に適用できる。布帛は、織物、編物の何れでもあることが できる。溶液は少なくとも重量で約2%、好ましくは約6%の架橋剤を含むこと ができる。触媒を使用する際には、溶液は触媒を少なくとも重量で約1%、好ま しくは約1%から約2%を含むことができる。 本発明による架橋性樹脂処理の後、布帛は加熱され架橋剤を固定しそしてキュ アーする。布帛は乾燥してもよい。加熱工程は、一部が乾燥ステップに先立って も又乾燥ステップに続けてもよい。加熱ステップて必要な時間と温度は、架橋化 剤の性質と適宜採用される触媒に依存する。加熱と適宜に乾燥を行った後、布帛 はセルロースの重量について計算して固定樹脂重量の少なくとも約0.5%、好 ましくは少なくとも1.0%、更に好ましくは少なくとも約2%含む。一般に、 布帛はセルロース重量について計算した架橋剤重量が約4%を超えない。一般に 、湿潤布帛中の架橋剤の約70%から90%がセルロースに固定されていること が判明した。 浴中の樹脂の濃度は樹脂の活性とキュアリングの効率によって、布帛に求めら れている固定樹脂付着量を与えるように選ばれる。 加熱と固定の後、布帛はセルロース布帛のに常用の加工プロセスに準じて洗滌 、乾燥される。 本発明により処理された布帛は、非常に低減したフィブリル化の程度を呈する 。これは、架橋処理が一般にセルロース布帛の摩擦抵抗性を減少させると考えら れていたので驚きである。本発明の方法は追加的な湿潤加工ステップが要り、そ して前記したような湿潤加工ステップは、リヨセル布帛のフィブリル化を起すこ とが知られている。本発明のより処理された布帛は、非処理布帛に比べて素晴ら しいフィブリル化抵抗性をもつものであり、衣類のような繊維製品の生産に適合 する。このような繊維製品は、洗濯でフィブリル化傾向の低減を殆ど失わないか 又はゆっくりと損なう程度である。 本発明の方法は、機械的な摩擦を起こすことが知られているロープ染色のよう な方法によって染色された布帛を含む染色済の布帛にも適用できる。これは本発 明の利点である。というのは布帛のロープ状加工は優れた風合いにつながる布帛 の嵩高化やリラックス処理を高めるからである。本発明の方法は、すでにフィブ リル化した、例えば酷くフィブリル化している布帛に適用することができる。高 度にフィブリル化している布帛を本発明の方法を適用して処理すると、意外なこ とに、処理した布帛は著しく低レベルのフィブリル化を呈することが判明した。 大抵の場合、高度のフィブリル化を呈する布帛は、費用のかかる付加的な加工を 必要としないと判断される並の製品と見做される。並の製品となる布帛が一級品 位の布帛及び繊維製品に変えられることは、本発明の特に優れた利点である。 試験方法1として以下に説明する方法を用いて、材料のフィブリル化の程度が 評価される。試験方法1(フィブリル化の評価) 普遍的に認められている標準的なフィブリル化評価方法はない。 そこで、以下の方法を用いてフィブリル化インデックス(F.I.)を評価した 。繊維のサンプルをフィブリル化度が増加する系列に並べた。各々のサンプルの 繊維の基準長を測り、基準長に沿ってフィブリル数(繊維の本体から延びる細い 毛状突起)を数えた。各フィブリルの長さを測り、フィブリル数に各フィブリル の平均長さを掛た積である数を各繊維について求めた。この積について最高値を 示す繊維を最もフィブリル化している繊維であるものとして、フィブリル化イン デックス(Fibrilation Index)10を割り付けた。全くフィ ビリルのない繊維をフィブリル化インデックス0を割り付け、残りの繊維を顕微 鏡観測で測った数に基づいて0から10の範囲で等しく割り付けた。 測定した繊維を用いて標準評価尺を作成した。他の任意の繊維試料のフィブリ ル化指数を測定するために、5又は10の繊維をこの標準評価尺と顕微鏡下で視 覚的に比較した。次いで、各々の繊維に対して視覚的に求めた数値を平均して、 試験対象試料に対応するフィブリル化指数とした。視覚測定と平均をとる方法は 、多くの場合実測法よりも迅速であことが理解できよう。熟練した繊維技術者達 は彼ら自身の繊維の評価について、一致することが明らかになっている。 布帛のフィブリル化指数は、布帛表面から引き抜いた繊維について評価できる 。約2.0から2.5以上ののフィブリル化指数を有する織物及び編物は、外観 の見栄えが良くない。 好ましい実施形態の説明 本発明を次の実施例により説明する。各々の例で使用された未だ一度も乾燥さ れたことのない(never−dried)繊維は、N−メチルモルホリン−N −オキシド(NMMO)のセルロース溶 液を水性浴に吐出し、形成された繊維を水でNMMOが無くなるまで洗滌するこ とによって調製されたものである。 実施例 F.I.が0のリヨセル100%の紡績糸織物を糊抜き、精錬次いでジェット 染色機で染色した。糊抜きは、1.5g/lの市販アミラーゼの水溶液を用いて 、pH6.5〜7.5、70°Cで、45分間で行なった。精錬は、炭酸ソーダ 2g/l及びアニオン洗滌剤2g/lを含む水溶液を用いて、95°Cで60分 間行なった。染色は4%owfの染料、Procion Navy HE−R1 50(Procionは、Zeneca plcの商標)、80g/lの硫酸ソ ーダ、及び20g/lの炭酸ソーダを含む水溶液を用いて、85°Cで、120 分間実施した。この布帛を先づは70°Cの水で、次いで雰囲気温度で濯ぎ、2 g/lのSandopur SR(SandpurはSandoz AGの商標 )を含む水溶液で95°C、20分ソーピング、水切りし、乾燥した。この方法 はセルロース布帛の典型的なロープ状処理プロセスである。処理された布帛は、 酷くフィブリル化され、F.I.は4.5を示した。 染色布帛サンプルを低ホルムアルデヒド樹脂DHDMEU(ヘキストAGから 商標Arkofix NG concで供給されている)の種々の量含む水溶液 でパッドした。この溶液は樹脂供給者の推奨にしたがいArkofix NG concの25重量%で酸放出触媒を含んでいた。布帛サンプルは、次いで11 0°Cで乾燥、次いで樹脂を180°Cでフラッシュキュアーした。サンプル布 帛は、次いでジェット染色機に再び仕掛けられ以前と同様に2回精錬した。次い で、サンプル布帛は脱水され、シリコーン系柔軟剤( Rudolf Chemical Ltd.から商標Rucofin A073 6入手可)50g/lを含む水分散液を湿潤したままの布帛にパッドし、110 °Cで乾燥した。結果を第1表に示す。 布帛上に固定された樹脂量の数値は、Arkofix NG concの70 %活性固形分、80%表示液及び80%キュアー効率に基づいて見積った値であ る。 これらの付加的な湿潤処理の間に、予想されたように非処理布のF.I.は4 .5から増加し、一方対照的に樹脂加工で布帛のF.I.は4.5から商業的に 許容可能なレベルの1.9又はそれ以下に実際上減少したことが判る。Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for reducing the degree of fibrillation and the tendency of fibrillation of solvent-spun cellulosic fibers, known as lyocell fibres. 2. Description of Related Art It is known that cellulose fibers can be obtained by extruding a solution of cellulose in its appropriate solvent into a coagulation bath. This process of extrusion and coagulation is referred to as solvent-spinning, and the cellulose fibers thus obtained are referred to as "solvent-spun" cellulose fibers. One example of such a method is described in US Pat. No. 4,246,221, the contents of which are incorporated herein by reference. Cellulose is soluble in solvents such as tertiary amine-N-oxides. The solution is extruded through a suitable die into filaments which are coagulated, washed with water to remove the solvent and dried. Generally, at some manufacturing stage, the filaments are cut into short lengths into staple fibers. It is also known that cellulose fibers can be produced by extruding a solution of a derivative of cellulose into a regeneration bath and a coagulation bath. An example of such a method is the viscose method. In the viscose method, the cellulose derivative is cellulose xanthate. Both such method types are examples of wet methods. The solvent spinning method has a number of advantages over known cellulosic fiber production methods such as the viscose method, such as reduced environmental emissions. The term "lyocell fiber" used herein means a cellulose fiber obtained by an organic solvent spinning method, and in the organic solvent spinning method, the solvent is a mixture of an organic chemical agent and water. In essence, solvent spinning consists of dissolving and spinning cellulose without the formation of cellulose derivatives. The term "solvent spun cellulose fiber" as used herein is synonymous with "lyocell fiber"). As used herein, a lyocell fabric means a fabric woven or knitted from a plurality of yarns containing lyocell fibers alone or in a blend at least in part. Fibers tend to fibrillate when subjected to mechanical stress, especially in the wet state. Fibrillation causes the fine fibrils to partly separate from the fibers when the fiber structure breaks in its longitudinal direction, giving the fibers or, for example, knitted fabrics containing them, a fluffy appearance. Dyed fabrics containing fibrillated fibers tend to have a frosted appearance, which is aesthetically undesirable. Such fibrillation is believed to occur due to mechanical rubbing of the fibers during processing in the wet or swollen state. Wetting processes such as refining, bleaching, dyeing and washing inevitably subject the fibers to mechanical abrasion. Higher temperature treatments and longer treatments tend to cause a greater degree of fibrillation. Lyocell fiber fabrics appear to be particularly sensitive to such friction. And it is often pointed out that it is easier to fibrillate than fabrics such as woven fabrics made from other types of cellulosic fibers. Cotton fibers are fibers which by nature have a particularly low tendency to fibrillate. EP-A-538,977 describes that fibrils are removed from fibrillated lyocell fiber fabrics by treatment with a solution of cellulase. Cellulase is an enzyme that has a catalytic action on the hydrolysis of cellulose. However, such treatment is not so desirable, and disposal of the used enzyme solution may cause environmental problems. Treating a cellulose fabric with a crosslinking agent to improve the wrinkle resistance of the cellulose fabric is described, for example, in Kirk-Othmer's Encyclopaedia of Chemical Technology, 22 (3), ed. Pp. 769-790, "Fiber (Finishing)", and H. Peter, Rev, Prog. Coloration, Vol. 17 (1987), pages 7-22, which has been known for many years. Cross-linking agents are sometimes referred to differently as, for example, cross-linkable resins, chemical finishes or resin finishes. The cross-linking agent is a small molecule substance containing a plurality of functional groups capable of reacting with the hydroxyl groups of cellulose to form cross-links. In a conventional type finish, the cellulosic fabric is first treated with a cross-linking agent, such as by applying a pad bath, dried, and heated to cure the resin and cause a cross-linking reaction to be processed ( Pad-dry-cure method). Wrinkle-proofing is known to impair the friction resistance, tensile strength and tear strength of cellulosic fabrics. Early cross-linking processing systems were with urea-formaldehyde and melamine-formaldehyde resins. These processing systems had many problematic drawbacks. This treatment method temporarily hardens the cloth because there is a resin adhering to the outside. The processed fabrics tended to produce an unpleasant odor during storage, which was due to the amine catalyst used to cure the resin and the toxic chemical agent formaldehyde. Therefore, it has been considered necessary to wash the processed fabric in order to remove the externally attached resin and the resin-forming by-product that emits an unpleasant odor. Such washing and subsequent drying of the treated fabric adds an additional burden to the cost of processing. Therefore, such processing systems have been largely replaced by systems containing so-called "low-formaldehyde resins" and "free-formaldehyde resins" as crosslinkers. One known example of such a treating agent is an N-methylol resin, ie a treating agent consisting of a small molecule compound containing two or more N-hydroxymethyl or N-alkoxymethyl, especially N-methoxymethyl groups. Is. The N-methylol resin is generally used in combination with a catalyst selected to improve the crosslinking performance. In a typical process, a solution containing about 5-9% by weight N-methylol resin crosslinker and 0.4-3.5% by weight acid catalyst is padded onto dry cellulosic fabric at 60-100% by weight pickup. The wet cloth is then dried and then heated to cure and fix the crosslinker. Fabrics treated with low-formaldehyde resins or non-formaldehyde resins generally do not undergo a temporary curing phenomenon and do not give off an unpleasant odor. Cured textile fabrics and processed garments are rarely washed before being sold to consumers. SUMMARY OF THE INVENTION A method of reducing the fibrillation tendency of a lyocell fabric according to the first aspect of the invention comprises the following steps: (a) treating the fabric with a low formaldehyde or aldehyde-free crosslinkable resin; (b) the fabric. Heating under conditions effective to cause the resin to react with the cellulose; (c) washing the fabric; and (d) drying the fabric. In this and other aspects of the invention, the fabric is treated with the crosslinkable resin in the form of a flat fabric and heated to cause a reaction between the cellulose and the resin in the form of the fabric fabric. In one particular embodiment of this and other aspects of the invention, the fabric being washed in the form of a flat fabric and heated, which is the preferred form, is then used for the production of garments and other textile articles. Cut into pieces. In yet another specific embodiment of this and other aspects of the invention, the fabric is first dressed into a garment or other fiber article, then washed and dried to form the invention. Complete. A method of reducing the degree of fibrillation of a lyocell fabric according to the second aspect of the present invention comprises the steps of: (a) treating the fabric with a low formaldehyde or aldehyde-free crosslinkable resin; Heating under conditions effective to cause a reaction between the resin and cellulose; (c) washing the fabric; and (d) drying the fabric. A method of reducing the degree of fibrillation of a lyocell fabric according to the third aspect of the present invention comprises the steps of: (a) refining and dyeing the fabric, thereby inducing fibrillation in the fabric: (b) Treating the fabric with a low formaldehyde or aldehyde-free crosslinkable resin; (c) heating the fabric under conditions effective to cause a reaction between the resin and cellulose; (d) the fabric. And (e) drying the fabric. In this third aspect of the invention, bleaching may optionally be carried out between the refining and dyeing process of step (a) and drying between steps (a) and (b) is also optional. is there. After step (c), the fabric may exhibit a high degree of fibrillation tendency to which the fibrous articles made therefrom are commercially unacceptable. After step (e), the flat or fibrous article-like fabric exhibits a very low commercially desirable degree of fibrillation. Preferred crosslinkable resins are N-methylol resins. Examples of suitable N-methylol resins are described in Kirk-Othmer and Petersen, supra. Such resins are, for example, 1,3-dimethylol ethylene urea (DEMU), 1,3-dimethylol propylene urea (DMPU) and 4,5-dihydroxy-1,3-dimethylol ethylene urea (DHDMEU). Contains. Other examples include urones, triazinones and carbamate compounds. Other examples of preferred crosslinkers consist of compounds based on 1,3-dialkyl-4,5-dihydroxy (alkoxy) ethyleneureas and their derivatives. A further example of a suitable crosslinking agent is melamine. A further example of a suitable crosslinker is butane tetracarboxylic acid (BTCA). One or more types of cross-linking agents may be used. A cross-linking agent for wrinkle-proofing of cellulose cloth is generally used in combination with a catalyst. The catalyst has a function of promoting a crosslinking reaction and resin curing and fixing. The method of the present invention preferably utilizes such catalysts when it is recommended to use them in combination with the crosslinker selected for use. For example, N-methylol resins are preferably used in combination with organic acid catalysts such as acetic acid or metal acid catalysts such as zinc nitrate or magnesium chloride. Latent acids such as ammonium salts, amine salts or metal salts can also be used. Mixed catalyst systems can also be used. The crosslinker and any catalyst are preferably applied to the fabric from a solution in water. This solution can be applied to the fabric in a known manner, for example by padding the fabric with the solution or by dipping the fabric in a treatment bath of the solution. The fabric can be either woven or knitted. The solution may contain at least about 2%, preferably about 6%, crosslinker by weight. When a catalyst is used, the solution may contain at least about 1% by weight catalyst, preferably about 1% to about 2%. After treatment with the crosslinkable resin according to the present invention, the fabric is heated to fix and cure the crosslinker. The fabric may be dried. The heating process may partly precede or follow the drying step. The time and temperature required for the heating step depends on the nature of the cross-linking agent and the catalyst employed as appropriate. After heating and optional drying, the fabric comprises at least about 0.5%, preferably at least 1.0%, more preferably at least about 2% by weight of the fixed resin, calculated on the weight of cellulose. Generally, the fabric has a crosslinker weight, calculated on cellulose weight, of no more than about 4%. It was generally found that about 70% to 90% of the crosslinker in the wet fabric was fixed to the cellulose. The concentration of resin in the bath is selected to give the required amount of fixed resin deposit on the fabric, depending on the activity of the resin and the efficiency of curing. After heating and fixing, the fabric is washed and dried according to the conventional processing processes for cellulosic fabrics. Fabrics treated according to the present invention exhibit a greatly reduced degree of fibrillation. This is surprising because the cross-linking treatment was generally thought to reduce the friction resistance of cellulosic fabrics. It is known that the method of the present invention requires an additional wet processing step, and that the wet processing step as described above causes fibrillation of the lyocell fabric. The more treated fabrics of the present invention have excellent resistance to fibrillation as compared to untreated fabrics and are compatible with the production of textiles such as garments. Such textiles have little or no slow loss of reduced fibrillation tendency upon washing. The method of the present invention is also applicable to dyed fabrics, including fabrics dyed by methods such as rope dyeing which are known to cause mechanical abrasion. This is an advantage of the present invention. This is because the rope-like processing of the fabric enhances the bulkiness and relaxation of the fabric, which leads to an excellent texture. The method of the present invention can be applied to fabrics that have already been fibrillated, for example heavily fibrillated. When highly fibrillated fabrics were treated by applying the method of the present invention, it was surprisingly found that the treated fabrics exhibit significantly lower levels of fibrillation. In most cases, fabrics exhibiting a high degree of fibrillation are considered mediocre products that are determined to require no costly additional processing. It is a particular advantage of the present invention that the fabrics that are mediocre products can be converted to first grade fabrics and textiles. The degree of fibrillation of the material is evaluated using the method described below as Test Method 1. Test Method 1 (Evaluation of fibrillation) There is no universally accepted standard fibrillation evaluation method. Therefore, the fibrillation index (FI) was evaluated using the following method. Fiber samples were arranged in series with increasing degrees of fibrillation. The reference length of the fiber of each sample was measured, and the number of fibrils (thin fibrils extending from the main body of the fiber) was counted along the reference length. The length of each fibril was measured, and a number, which was the product of the number of fibrils times the average length of each fibril, was determined for each fiber. A fibrillation index of 10 was assigned as the fiber having the highest fibrillation value for this product as the most fibrillated fiber. Fibers without any fibrillation were assigned a fibrillation index of 0, and the remaining fibers were evenly assigned in the range 0 to 10 based on the numbers measured by microscopy. A standard evaluation scale was prepared using the measured fibers. Fibers of 5 or 10 were visually compared under microscope to this standard scale to determine the fibrillation index of any other fiber sample. Then, the numerical values visually obtained for each fiber were averaged to obtain a fibrillation index corresponding to the test sample. It can be seen that the visual measurement and averaging method is often faster than the actual measurement method. Skilled textile engineers have been shown to agree on their own assessment of the fibers. The fibrillation index of a fabric can be evaluated for fibers drawn from the surface of the fabric. Woven and knitted fabrics having a fibrillation index of about 2.0 to 2.5 and above have a poor appearance. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is illustrated by the following examples. The never-dried fiber used in each example was prepared by discharging a cellulose solution of N-methylmorpholine-N-oxide (NMMO) into an aqueous bath to form the formed fiber. It was prepared by washing with water until the NMMO was gone. Example F. I. A lyocell 100% spun yarn fabric of No. 0 was desizing, refined and then dyed with a jet dyeing machine. Desizing was carried out at a pH of 6.5 to 7.5 at 70 ° C. for 45 minutes using an aqueous solution of 1.5 g / l of commercial amylase. The refining was carried out at 95 ° C. for 60 minutes using an aqueous solution containing 2 g / l of sodium carbonate and 2 g / l of anionic detergent. The dyeing was carried out at 85 ° C. using an aqueous solution containing 4% owf dye, Procion Navy HE-R1 50 (Procion is a trademark of Zeneca plc), 80 g / l sodium sulfate, and 20 g / l sodium carbonate. It was carried out for 120 minutes. The fabric is first rinsed with water at 70 ° C., then at ambient temperature, soaped at 95 ° C. for 20 minutes in an aqueous solution containing 2 g / l Sandopur SR (Sandpur is a trademark of Sandoz AG), drained and dried. did. This method is a typical rope-like treatment process for cellulosic fabrics. The treated fabric was severely fibrillated, I. Showed 4.5. The dyed fabric samples were padded with an aqueous solution of various amounts of the low formaldehyde resin DHDMEU (supplied by Hoechst AG under the trademark Arkofix NG conc). The solution contained the acid releasing catalyst at 25% by weight of Arkofix NG conc according to the resin supplier's recommendations. The fabric sample was then dried at 110 ° C and then the resin was flash cured at 180 ° C. The sample fabric was then remounted on the jet dyer and scoured twice as before. The sample fabric was then dewatered, padded on the as-wet fabric with an aqueous dispersion containing 50 g / l of a silicone-based softener (available from Rudolf Chemical Ltd. under the trademark Rucofin A0736) and dried at 110 ° C. The results are shown in Table 1. The numerical value of the amount of resin fixed on the fabric is an estimated value based on 70% active solids of Arkofix NG conc, 80% indicator liquid and 80% cure efficiency. During these additional wet treatments, as expected, the F. I. Is 4. 5 while the F. I. It can be seen that is actually reduced from 4.5 to a commercially acceptable level of 1.9 or less.
