【発明の属する技術分野】
本発明は、濃色に染色されているにも拘わらず、水に対する堅牢度が良好で、洗濯等による色落ちのない濃色性ポリエステル布帛及びその製造方法に関するものである。
【０００２】
【従来の技術】
従来より、フォーマル衣料用布帛は主にブラックに染色されることが多く、色の深みをさらに向上させるために、染色後にその表面を樹脂で被覆する、いわゆる樹脂加工を施された後、高温で乾燥されるのが一般的であった。
【０００３】
しかしながら、上記のような樹脂加工を施された布帛を洗濯する場合、通常の洗濯では乾燥時の熱で昇華した余剰の染料が脱落し、色落ちの原因となるので、ドライクリーニングを行うことが必須であった。
【０００４】
ところが、近年、環境問題に対する配慮から、ドライクリーニングの際に使用する溶剤を規制する動きがあり、通常の洗濯や水洗いを行っても色落ちが発生しない、樹脂加工を施されたフォーマル衣料用布帛が切望されていた。
【０００５】
【発明が解決しようとする課題】
本発明の目的は、上記従来技術の有する問題点を解消し、通常の洗濯や水洗いを行っても色落ちが発生しない、樹脂加工を施された濃色性ポリエステル布帛、特にブラックなどの濃色に染色されたフォーマル衣料用布帛を提供することにある。
【０００６】
【課題を解決するための手段】
本発明者は上記目的を達成するために鋭意検討した結果、濃色に染色され、樹脂加工を施された布帛を拡布状態で水洗し、好ましくは低温で熱セットするとき、水に対する堅牢度が良好な布帛が得られることを究明した。
【０００７】
かくして、本発明によれば、（１）染色されたポリエステル繊維を８０重量％以上含み、フッ素系またはシリコン系またはウレタン系の樹脂でその表面が被覆され、布帛のＬ値が１０．５以下、水堅牢度の変退色、汚染がいずれも４級以上で、且つ洗濯堅牢度の変退色、汚染がいずれも４級以上である濃色性ポリエステル布帛の製造方法であって、ポリエステル繊維を８０重量％以上含む布帛を染色し、フッ素系またはシリコン系またはウレタン系の樹脂によりその表面を被覆した後、さらに拡布状態で水洗することを特徴とする濃色性ポリエステル布帛の製造方法が提供される。
【０００８】
【発明の実施の形態】
本発明の布帛は、８０重量％以上のポリエステル繊維を含む。ここで、ポリエステル繊維とは、テレフタル酸を主たる酸成分とし、炭素数２〜６のアルキレングリコール、即ちエチレングリコール、トリメチレングリコール、テトラメチレングリコール、ペンタメチレングリコール、ヘキサメチレングリコールからなる群から選ばれた少なくとも１種のグリコール、特に好ましくはエチレングリコールまたはテトラメチレングリコールを主たるグリコール成分とするポリエステルからなる繊維を対象とする。
【０００９】
また、上記ポリエステルは、テレフタル酸成分の一部を他の二官能性カルボン酸成分で置き換えたポリエステルであってもよく、グリコール成分の一部を上記グリコール以外のジオール成分で置き換えたポリエステルであってもよい。ここで使用されるテレフタル酸以外の二官能性カルボン酸としては、例えば、イソフタル酸、ナフタレンジカルボン酸、ジフェニルジカルボン酸、ジフェノキシジカルボン酸、β−アジピン酸、セバシン酸、１，４−シクロヘキサンジカルボン酸のような芳香族、脂肪族、脂環族の二官能性カルボン酸を上げることができる。
【００１０】
さらに、上記グリコール以外の化合物としては、例えば、シクロヘキサン−１，４−ジメタノール、ネオペンチルグリコール、ビスフェノールＡ、ビスフェノールＳのごとき 脂肪族、脂環族、芳香族のジオール化合物をあげることができる。
【００１１】
本発明においては、上記ポリエステル繊維を８０重量％以上含んだ状態で、常法により織物、編物、或いは不織布等の布帛を形成させる。この際、布帛の組織や密度等には特に制限はなく、従来公知の組織等が任意に採用できる。
【００１２】
また、該布帛には、上記ポリエステル繊維が８０重量％以上含まれていれば良く、２０重量％未満の他の合成繊維、天然繊維、或いは半合成繊維などを混繊、混紡、交織編或は混綿などの形で含んでいても構わない。
【００１３】
次いで、上記の布帛は染色されるが、この際、後述するＬ値が１０．５以下となるような濃色に染色すれば、本発明の効果が顕著に発現する。その理由は、ブラックなどの濃色に染色された場合は、元々染料の使用量が多いので、後述する乾燥時の熱で昇華する染料の量が多い上、染料が脱落した際の色落ちが一層目立つという問題があるのに対し、淡色に染色された場合は、昇華する染料の絶対量が少ない上、そもそも色落ちが目立ちにくいからである。
【００１４】
本発明においては、上記の染色ポリエステル布帛に、水系樹脂、例えばフッソ系、シリコン系、ウレタン系の樹脂を付与し、該水系樹脂によりその表面を被覆した後、さらに拡布状態で水洗することが肝要である。
【００１５】
上記のような水洗を行うことにより、乾燥時の熱で昇華した染料を洗い落とすことができ、フォーマル衣料等の製品となった後の色落ちを可及的に防止することが可能となる。
【００１６】
また、上記の水洗に際しては、単なる水洗処理を行うだけではシワが発生し、このシワを取るためのシワ伸ばし工程で熱を受けると再度染料の昇華が起こり、製品となった後の色落ちが発生するので、拡布状態で水洗処理を行なうことが必要である。
【００１７】
さらに、上記布帛の水洗後の乾燥や仕上げ工程においては、できるだけ低温で熱セットを行い、新たに発生する染料の昇華を抑制することが好ましい。
【００１８】
かくして得られたポリエステル布帛は、水系樹脂でその表面が被覆されているので、色の深みが増しており、該布帛のＬ値が１０．５以下であるにも拘わらず、水堅牢度の変退色、汚染がいずれも４級以上で、且つ洗濯堅牢度の変退色、汚染がいずれも４級以上という良好な堅牢度を有しており、通常の洗濯や水洗いを行っても色落ちが発生しない。
【００１９】

BACKGROUND OF THE INVENTION
The present invention relates to a dark-colored polyester fabric that has good fastness to water and has no color fading due to washing, etc., even though it is dyed dark, and a method for producing the same.
[0002]
[Prior art]
Conventionally, fabrics for formal garments are often dyed mainly in black, and in order to further improve the color depth, the surface is coated with a resin after dyeing, so-called resin processing, and then at a high temperature. It was common to be dried.
[0003]
However, when washing a fabric that has been subjected to the resin processing as described above, in ordinary washing, excess dye sublimated by heat at the time of drying may fall off and cause color fading, so dry cleaning can be performed. It was essential.
[0004]
However, in recent years, there has been a movement to regulate the solvent used in dry cleaning in consideration of environmental problems, and the fabric for formal clothing that has been subjected to resin processing that does not cause discoloration even after ordinary washing or washing with water. Was anxious.
[0005]
[Problems to be solved by the invention]
The object of the present invention is to eliminate the above-mentioned problems of the prior art and to prevent color fading even when ordinary washing or washing with water is performed. An object of the present invention is to provide a fabric for formal garments dyed.
[0006]
[Means for Solving the Problems]
As a result of diligent studies to achieve the above object, the present inventor has shown that when a fabric dyed in dark color and subjected to resin processing is washed with water in an expanded state, and preferably heat-set at a low temperature, the fastness to water is high. It has been determined that a good fabric can be obtained.
[0007]
Thus, according to the present invention, (1) the dyed polyester fiber is contained in an amount of 80% by weight or more, the surface thereof is coated with a fluorine-based, silicon-based or urethane-based resin, and the L value of the fabric is 10.5 or less. A method for producing a dark-colored polyester fabric having both water fastness discoloration and contamination of grade 4 or higher and washing fastness discoloration and contamination of grade 4 or higher, comprising 80 weight of polyester fiber A method for producing a dark-colored polyester fabric, characterized in that a fabric containing at least% is dyed and coated with a fluorine-based, silicon-based or urethane-based resin, and then washed with water in an expanded state .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The fabric of the present invention contains 80% by weight or more of polyester fiber. Here, the polyester fiber is selected from the group consisting of terephthalic acid as the main acid component, and alkylene glycol having 2 to 6 carbon atoms, that is, ethylene glycol, trimethylene glycol, tetramethylene glycol, pentamethylene glycol, and hexamethylene glycol. Further, a fiber made of polyester having at least one glycol, particularly preferably ethylene glycol or tetramethylene glycol as a main glycol component, is an object.
[0009]
The polyester may be a polyester in which a part of the terephthalic acid component is replaced with another difunctional carboxylic acid component, and a polyester in which a part of the glycol component is replaced with a diol component other than the glycol. Also good. Examples of the bifunctional carboxylic acid other than terephthalic acid used here include isophthalic acid, naphthalenedicarboxylic acid, diphenyldicarboxylic acid, diphenoxydicarboxylic acid, β-adipic acid, sebacic acid, and 1,4-cyclohexanedicarboxylic acid. Aromatic, aliphatic and alicyclic bifunctional carboxylic acids such as can be raised.
[0010]
Furthermore, examples of the compounds other than the glycol include aliphatic, alicyclic, and aromatic diol compounds such as cyclohexane-1,4-dimethanol, neopentyl glycol, bisphenol A, and bisphenol S.
[0011]
In the present invention, a fabric such as a woven fabric, a knitted fabric, or a non-woven fabric is formed by a conventional method in a state containing 80% by weight or more of the polyester fiber. At this time, the structure and density of the fabric are not particularly limited, and a conventionally known structure or the like can be arbitrarily employed.
[0012]
Further, the fabric may contain 80% by weight or more of the polyester fiber, and other synthetic fiber, natural fiber, semi-synthetic fiber, etc. less than 20% by weight may be mixed, blended, knitted or knitted. It may be included in the form of blended cotton.
[0013]
Next, the fabric is dyed. At this time, the effect of the present invention is remarkably exhibited if the fabric is dyed in a dark color having an L value described below of 10.5 or less. The reason for this is that when dyed in a dark color such as black, the amount of dye used is originally large, so there is a large amount of dye that sublimes with the heat of drying described later, and the color fading when the dye falls off. This is because the problem of being more noticeable is that when dyed in a light color, the absolute amount of dye that sublimates is small, and the color fading is hardly noticeable in the first place.
[0014]
In the present invention, it is important to add a water-based resin, for example, a fluorine-based resin, a silicon-based resin, or a urethane-based resin to the above-mentioned dyed polyester fabric, coat the surface with the water-based resin, and then wash with water in an expanded state. It is.
[0015]
By washing with water as described above, the dye sublimated by the heat at the time of drying can be washed away, and it becomes possible to prevent as much as possible the color fading after becoming a product such as formal clothing.
[0016]
In addition, in the above water washing, wrinkles are generated only by performing a water washing treatment, and when heat is received in the wrinkle stretching process for removing the wrinkles, the dye sublimation occurs again, and the color loss after becoming a product is lost. Since it occurs, it is necessary to carry out a water washing process in the expanded state.
[0017]
Furthermore, in the drying or finishing step after washing the fabric with water, it is preferable to perform heat setting at as low a temperature as possible to suppress newly generated dye sublimation.
[0018]
Since the surface of the polyester fabric thus obtained is coated with a water-based resin, the color depth is increased, and the water fastness changes even though the L value of the fabric is 10.5 or less. Both fading and contamination are grades 4 and above, and the fastness to washing fastness and discoloration are both grade 4 and above, and color fading occurs even after normal washing and washing. do not do.
[0019]
