【発明の詳細な説明】 ウール及び／又は他の天然繊維の光漂白防止法 技術分野 本発明は、ウール及び／又は天然繊維がガラス越し等に最初に太陽光に曝され たとき、ウール及び他の同様の天然繊維の漂白を減少させるか又は防止するため の方法に関するものである。 技術背景 光漂白(photobleaching)（時々“初期退色(first fade)”又は“赤やけ(red f ade)”といわれる）は、ウール本来のクリーム色の迅速ではあるが限定されたオ ントーン退色としてあらわれる。 例えば、乾熱、熱水又はアルカリ黄変といった処理から誘発される黄色度はま た光漂白性である。 光漂白の大部分は、ウールがガラス越しに真夏の太陽光に曝されると５〜１０ 時間で起こり、さらに４０〜５０時間でよりゆっくりした速度で続く。 光漂白により引き起こされる色の変化は、特にカーペットの場合、非常に多く の消費者の苦情の原因となる。家具を動かしたときにあらわれる、太陽光に曝さ れていた部分のカーペットと曝されていなかった部分のカーペットとの色が違っ てくることに注目されたい。 本発明の主な目的は、太陽光に曝されたときに起こるウール又はウールを混合 する調度品の最初の色の変化を減少させるか又は防止し、この原因による消費者 の苦情を除くことである。 発明の概要 本発明の観点の一つにより、天然繊維を化合物により処理する方法を提供し、 ここで、該化合物は、天然繊維が光漂白するのと同様の速度で光黄変し、天然繊 維上の該化合物の光黄変が天然繊維の光漂白を相殺する程度の量で該化合物を施 す。 好ましいクラスの化合物は、シンタン(syntans)として工業的に公知であり、 芳香族スルホネート類及び／又はスルホン酸類の縮合物からなることができる。 しかしながら、ウール等の繊維が光漂白するのと同様の速度で、光黄変する他 の化合物もまた適している。これらは、蛍光増白剤、タンニン、芳香族スルホン 酸等を含むことができる。図面の簡単な説明 本発明のさらなる観点が、添付の図面を参照することにより、以下の記載から 明らかになるであろう。 図１は、芳香族スルホン酸縮合物で処理したウールフェルトを、４０時間にわ たって太陽光に曝したときの黄色度の変化のグラフを示す。 図２は、芳香族スルホン酸縮合物で処理した一層白いウールフェルトを、４０ 時間にわたって太陽光に曝したときの黄色度の変化のグラフを示す。 図３は、処理した及び処理していないヤーンを、４０時間にわたって太陽光に 曝したときの黄色への変化のグラフを示す。 図４は、処理した及び処理していないヤーンを、４０時間にわたって太陽光に 曝したときの黄色への変化のグラフを示す。好ましい実施例の説明 本発明の具体的な実施例を以下に記載する。 実施例１ 黄色度の異なる精錬した目の荒いウールサンプルをアリールスルホン酸の縮合 物で以下のように処理した： ウールサンプル（２０ｇ）を実験室用染色装置中で、７５℃において、ウール の重量を基準として（ｏｗｗ）、０、0.5％又は１％の縮合物で処理した。 これらのサンプルを濯いで、６０℃において乾燥し、手で梳き、充填密度0.10 ｇ／ｃｃで、ガラス縁の容器に詰めた。 黄色度値（Ｙ−Ｚ三刺激値）を、２°オブザーバー及び光源Ｃを用いるハンタ ーラボ(Hunterlab)分光色彩計を用いて、真夏の太陽光に４０時間曝す前後で測 定した（クライストチャーチ、ニュージーランド）。 結果を以下に示す。 従って、太陽光に４０時間曝露後のウールサンプルの黄色味の変化は、それぞ れ７３％及び８８％減少した。 実施例２ 黄色度の異なる２種のウールフェルトを、０、0.25、0.5、0.75及び１％の芳 香族スルホン酸で処理した。つぎに、サンプルをガラス越しに真夏の太陽光に曝 し、実施例１のようにハンターラボ分光色彩計を用いて、１、２、５、１０、２ ０及び４０時間後の黄色度を測定した。 結果を図１及び２に示す。 図１及び２から、元々の黄色度が異なるウールは、変色を防ぐのに必要な化学 物質の量が異なることが分かる。図１により、芳香族スルホン酸縮合物の量を増 加すると、光漂白の程度が減少することが分かる。１％ｏｗｗにおいて、変色が 最小であることが認められる。一層白いウールについての結果（図２）より、処 理割合が0.5％ｏｗｗのとき最高の結果が得られることがわかる。 実施例３ 商品であるヤーンのバッチ２トンを染色中に、処理を施した。サンドラン(San dolan)ＭＦダイ(サンドーズ(Sandoz))を用い、0.8％において、ロングク ローズシングルスティックかせ染色機中で染色を行った。標準助剤並びに１％ヒ ドロキシルアンモニウムスルフェート（ＨＡＳ）及び0.5％芳香族スルホン酸を 染色開始時に添加した。ウール混合物のＹ−Ｚ値は4.6であった。この処理した バッチからのサンプル並びに先に染色したバッチからの処理していないサンプル 及び処理も染色もしていないウールを、２ｍｍのピクチャーガラス越しに真夏の 太陽光に曝した（クライストチャーチ、ニュージーランド）。曝露前及び曝露後 １、２、５、１０、２０及び４０時間の色の測定を、ハンターラボ分光色彩計を 用いて行った。黄色度の変化をΔ（Ｙ−Ｚ）として記録し、図３に示した。図３ において、太陽光に４０時間曝した後は、処理したヤーンは0.3Ｙ−Ｚユニット 変化した（即ち、識別不可能である）が、処理していないヤーンは、2.3Ｙ−Ｚ ユニット変化した（１より大きいΔ（Ｙ−Ｚ）の変化は、目視により識別可能で あると言われている）。 実施例４ 商業用の目の荒い素材を染色している間に、最初のＹ−Ｚの値が3.0のウール のバッチ2.8トンに処理を施した。各々が２３５ｋｇの１２本のロットからなる 染色物を、２：１の含金属染料で染色し、ライトベージュシェード（0.013％染 料）とした。１％ＨＡＳを含む他の染料助剤を用いて処理を行った。芳香族スル ホン酸の濃度は0.4％である。１２本の染色物を混合し、５ロールテープスカウ ア(bowl tape scour)中で精錬されるヤーンに加工処理した。その後、メタビス ルフィットナトリウム１０ｇ／Ｌを用いて、さらに５ロール化学定着処理を行っ た。そのヤーンを、同様に、２ｍｍのピクチャーガラス越しに真夏の太陽光に４ ０時間曝した。処理していないコントロールサンプル及び染色／処理ともにして いないウールサンプルもまた曝露した。ハンターラボ分光色彩計を用いて、０、 １、２、５、１０、２０及び４０時間曝露において色測定を行った。Δ（Ｙ−Ｚ ）値（黄色度の変化）を図４に示す。図４により、４０時間曝露後の、処理した ヤーンが0.2Ｙ−Ｚユニット変化しており、処理していないヤーンが1.5Ｙ−Ｚユ ニット変化していることが分かる。 この実施例から、染色中に施されたとき、テープスカウア及び化学定着に対す る処理が速いことが分かる。 ウールは、精錬中、染色段階又は連続的なカーペット加工ラインにおいて処理 することができる。処理は、目の荒いウール、ウールヤーン、ウール織物又はカ ーペットに施すことができる。 施される化合物の濃度は、ウールの最初の黄色度及び使用する染料に依存する が、ガラス越しの光漂白による変色がほとんどないか全くないように調節するこ とができる。 １〜２％のヒドロキシルアンモニウムスルフェート（ＨＡＳ）を染色助剤に添 加することにより、染浴黄変を有意に減少し、必要とされるシンタン化合物の量 を少なくすることができる。このため、１〜２％のＨＡＳをシンタン化合物と混 合して使用することが好ましい。 従って、本発明により、ガラス越し等で、太陽光に曝されている間にウール及 び他の同様の天然繊維の漂白を減少させるか又は防止する方法を提供する。 本発明の具体的な実施例が記載されているが、本発明の範囲及び添付の請求の 範囲からはずれずに改良や変更を行うことができると思われる。Description: FIELD OF THE INVENTION The present invention relates to a method for preventing wool and / or other natural fibers from light bleaching when the wool and / or natural fibers are first exposed to sunlight, such as through glass. And methods for reducing or preventing bleaching of natural fibers. TECHNICAL BACKGROUND Photobleaching (sometimes referred to as "first fade" or "red fade") manifests as a rapid but limited on-tone fade of wool's natural cream color. For example, yellowness induced from treatments such as dry heat, hot water or alkaline yellowing is also photobleachable. The majority of light bleaching occurs in 5-10 hours when the wool is exposed to midsummer sunlight through the glass, and continues at a slower rate in an additional 40-50 hours. The color change caused by light bleaching, especially in the case of carpets, causes a great deal of consumer complaints. Note that the color of the carpet that appeared when the furniture was moved was different from the carpet that was exposed to sunlight and the carpet that was not exposed. A primary object of the present invention is to reduce or prevent the initial color change of wool or wool-mixing furnishings that occurs when exposed to sunlight, and to eliminate consumer complaints due to this cause. is there. SUMMARY OF THE INVENTION According to one aspect of the present invention, there is provided a method of treating natural fiber with a compound, wherein the compound light yellows at a rate similar to that of natural fiber photobleaching. The compound is applied in an amount such that the photoyellowing of the compound above offsets the photobleaching of the natural fiber. A preferred class of compounds is known industrially as syntans and can consist of condensates of aromatic sulfonates and / or sulfonic acids. However, other compounds that light yellow, at a rate similar to that of fibers such as wool that light bleach, are also suitable. These can include optical brighteners, tannins, aromatic sulfonic acids, and the like. BRIEF DESCRIPTION OF THE DRAWINGS Further aspects of the present invention will become apparent from the following description, taken in conjunction with the accompanying drawings. FIG. 1 shows a graph of the change in yellowness when wool felt treated with an aromatic sulfonic acid condensate is exposed to sunlight for 40 hours. FIG. 2 shows a graph of the change in yellowness of a whiter wool felt treated with an aromatic sulfonic acid condensate when exposed to sunlight for 40 hours. FIG. 3 shows a graph of the change in yellow color of treated and untreated yarns when exposed to sunlight for 40 hours. FIG. 4 shows a graph of the change in yellow color of treated and untreated yarns when exposed to sunlight for 40 hours. DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention are described below. Example 1 A refined open wool sample of different yellowness was treated with a condensate of an aryl sulfonic acid as follows: A wool sample (20 g) was weighed at 75 ° C in a laboratory dyeing apparatus. Treated with 0, 0.5% or 1% condensate based on (ow). The samples were rinsed, dried at 60 ° C., carded by hand and packed in glass-rimmed containers at a packing density of 0.10 g / cc. Yellowness values (YZ tristimulus values) were measured before and after 40 hours of exposure to midsummer sunlight using a Hunterlab spectrocolorimeter using a 2 ° observer and light source C (Christchurch, New Zealand). ). The results are shown below. Thus, the change in yellowness of the wool sample after 40 hours of exposure to sunlight was reduced by 73% and 88%, respectively. Example 2 Two wool felts of different yellowness were treated with 0, 0.25, 0.5, 0.75 and 1% aromatic sulfonic acids. Next, the sample was exposed to midsummer sunlight through glass, and the yellowness after 1, 2, 5, 10, 20, and 40 hours was measured using a Hunter Lab spectral colorimeter as in Example 1. . The results are shown in FIGS. It can be seen from FIGS. 1 and 2 that wools with different yellowness originally require different amounts of chemicals to prevent discoloration. FIG. 1 shows that increasing the amount of the aromatic sulfonic acid condensate reduces the degree of photobleaching. At 1% www, it is observed that discoloration is minimal. The results for the whiter wool (FIG. 2) show that the best results are obtained when the treatment ratio is 0.5% ow. Example 3 A 2 ton batch of commercial yarn was treated during dyeing. Staining was performed in a long-closed single-stick skein dyeing machine at 0.8% using a San dolan MF die (Sandoz). Standard auxiliaries and 1% hydroxylammonium sulfate (HAS) and 0.5% aromatic sulfonic acid were added at the start of the dyeing. The YZ value of the wool mixture was 4.6. Samples from this treated batch as well as untreated samples from previously dyed batches and untreated and unstained wool were exposed to midsummer sunlight through 2 mm picture glass (Christchurch, New Zealand). Color measurements were made before and at 1, 2, 5, 10, 20 and 40 hours post-exposure using a Hunter Lab spectrocolorimeter. The change in yellowness was recorded as Δ (YZ) and is shown in FIG. In FIG. 3, after 40 hours of exposure to sunlight, the treated yarn changed 0.3 YZ units (i.e., was indistinguishable), while the untreated yarn changed 2.3 YZ units. (Changes in Δ (YZ) greater than 1 are said to be visually identifiable). Example 4 An initial 2.8 ton batch of 2.8 tons of wool having a YZ value was treated while dyeing a commercial open material. Each dyed product consisting of 12 lots of 235 kg was dyed with a metal-containing dye of 2: 1 to obtain a light beige shade (0.013% dye). The treatment was carried out with other dye auxiliaries containing 1% HAS. The concentration of aromatic sulfonic acid is 0.4%. The twelve dyeings were mixed and processed into yarns that were refined in a five roll tape scour. Thereafter, 5 roll chemical fixing treatment was further performed using 10 g / L of sodium metabisulfite. The yarn was similarly exposed to midsummer sunlight through a 2 mm picture glass for 40 hours. Untreated control samples and wool samples with no staining / treatment were also exposed. Color measurements were made using a HunterLab spectrocolorimeter at 0, 1, 2, 5, 10, 20, and 40 hours exposure. FIG. 4 shows the Δ (YZ) value (change in yellowness). FIG. 4 shows that the treated yarn has changed by 0.2 YZ units and the untreated yarn has changed by 1.5 YZ units after 40 hours of exposure. This example shows that the treatment for tape scour and chemical fixation is fast when applied during dyeing. Wool can be processed during refining, in the dyeing stage, or in a continuous carpet processing line. The treatment can be applied to open wool, wool yarn, wool fabric or carpet. The concentration of the compound applied depends on the initial yellowness of the wool and the dye used, but can be adjusted so that there is little or no discoloration due to photobleaching through the glass. By adding 1-2% hydroxylammonium sulfate (HAS) to the dyeing aid, dyeing bath yellowing can be significantly reduced and the amount of syntan compound required can be reduced. For this reason, it is preferable to use 1-2% of HAS in a mixture with the syntan compound. Thus, the present invention provides a method for reducing or preventing bleaching of wool and other similar natural fibers during exposure to sunlight, such as through glass. While specific embodiments of the present invention have been described, it is contemplated that modifications and changes may be made without departing from the scope of the present invention and the appended claims.
