Description
本発明は、繊維製品に耐ドライクリーニング性に優れた撥水加工を施すに適した繊維用撥水剤組成物及び繊維製品の撥水加工処理方法並びに撥水加工処理を施した絹繊維製品に関する。 TECHNICAL FIELD The present invention relates to a water repellent composition for fibers suitable for performing a water repellent process excellent in dry cleaning resistance on a fiber product, a water repellent process method for a fiber product, and a silk fiber product subjected to a water repellent process. .
従来から、繊維用撥水剤としてはポリフッ素化アルキルアクリレートを主体とするフッ素樹脂系撥水剤が主として用いられ、この樹脂組成物を水に分散させた水系撥水剤、溶剤に溶解した溶剤系撥水剤を繊維製品に含浸させた後、乾燥、熱処理を行う方法がよく知られていた。ポリエステル等の合成繊維製品にこの方法を適用した場合、１６０℃前後の熱処理を施すので初期の撥水性は十分でドライクリーニング時の耐久性もかなりあるが、風合いがやや硬くなる傾向にある。しかし、絹繊維製品など高温熱処理が出来ない繊維製品の場合には通常１２０℃前後の熱処理を施すので、得られる初期の撥水性もやや低く、洗濯耐久性、特に耐ドライクリーニング性が著しく悪いという欠点があった。 Conventionally, as a water repellent for fibers, a fluororesin-based water repellent mainly composed of polyfluorinated alkyl acrylate is mainly used. A water-based water repellent in which this resin composition is dispersed in water, a solvent dissolved in a solvent. A method of drying and heat treatment after impregnating a fiber product with a water repellent is well known. When this method is applied to a synthetic fiber product such as polyester, a heat treatment at about 160 ° C. is performed, so that the initial water repellency is sufficient and the durability during dry cleaning is considerable, but the texture tends to be slightly hard. However, in the case of fiber products that cannot be heat-treated at high temperature, such as silk fiber products, heat treatment is usually performed at around 120 ° C., so that the initial water repellency obtained is somewhat low, and washing durability, particularly dry cleaning resistance, is extremely poor. There were drawbacks.
この欠点に対し、各種樹脂組成物との併用によって耐洗濯性とりわけ耐ドライクリーニング性を改善しようとする試みがなされているが、未だに満足できる方法は確立されていない。 In order to cope with this drawback, attempts have been made to improve washing resistance, particularly dry cleaning resistance, in combination with various resin compositions, but a satisfactory method has not yet been established.
一方、フッ素樹脂系撥水剤を揮発性溶剤に溶解したいわゆるスプレー式撥水剤も各種市販されている。この場合は室温で処理できるため、素材の制限もなく風合い、変色等の問題もないが、洗濯耐久性が悪く、特に耐ドライクリーニング性が悪い。 On the other hand, various so-called spray-type water repellents in which a fluororesin water repellent is dissolved in a volatile solvent are also commercially available. In this case, since the treatment can be performed at room temperature, there is no limitation on the material and there are no problems such as texture and discoloration, but the washing durability is poor, and particularly the dry cleaning resistance is bad.
そこで、特許文献１においては、かかる問題を解決するために、水酸基含有シリコーンオイル、アミノ変性シリコーンオイル及び石油系ドライクリーニング溶剤を含有するドライクリーニング用撥水剤組成物についての発明を開示している。かかるドライクリーニング用撥水剤組成物を用いることによって、従来のドライクリーニング設備を用いて繊維製品に簡単に撥水加工できるとともに、泡立ちが少なくかつ撥水性能に優れたドライクリーニング用撥水剤組成物を提供できるとしている。
しかしながら、上記特許文献１に記載のドライクリーニング用撥水剤組成物は、撥水性能及び耐ドライクリーニング性においては優れた効果が得られるが、繊維製品の風合いが損なわれたり、ぬめり感を生じる場合がある。即ち、この組成物を用いる方法によれば、洗濯耐久性ある撥水加工が可能であるが、撥水樹脂の付着量がかなりあるためややぬめり感のある風合いとなり、ドライクリーニングをさらに繰り返せばやはり撥水性の低下をきたすようになるという問題点があった。 However, the water-repellent composition for dry cleaning described in Patent Document 1 has an excellent effect in water repellency and dry cleaning resistance, but the texture of the fiber product is impaired or a slimy feeling is generated. There is a case. That is, according to the method using this composition, washing-resistant water-repellent processing is possible, but since the amount of water-repellent resin attached is considerable, it becomes a slightly slimy texture, and if dry cleaning is further repeated, There was a problem that water repellency was lowered.
そこで、本発明は、繊維製品の風合いを損なうことなく、ぬめり感を生じることもなく、処理対象とする繊維製品を極めて撥水性に優れかつ洗濯耐久性とりわけ耐ドライクリーニング性に優れた撥水繊維製品とすることができる繊維用撥水剤組成物及び繊維製品の撥水加工処理方法並びに耐ドライクリーニング性に優れた絹繊維製品を提供することを課題とするものである。 Accordingly, the present invention provides a water-repellent fiber that is excellent in water repellency and excellent in washing durability, particularly in dry cleaning resistance, without affecting the texture of the fiber product and without causing a feeling of sliminess. It is an object of the present invention to provide a water repellent composition for fibers that can be made into a product, a water repellent processing method for fiber products, and a silk fiber product excellent in dry cleaning resistance.

請求項７の発明にかかる繊維用撥水剤組成物は、水酸基含有シリコーンオイルが水酸基含有ポリアルキルシロキサンであり、フッ素樹脂系撥水剤がポリフッ素化アルキルアクリレートであるものである。本発明者らはフッソ樹脂系撥水剤の活用を図るため適切なバインダー樹脂としての水酸基含有シリコーンオイルについて鋭意実験研究を重ねた結果、水酸基含有ポリアルキルシロキサンとポリフッ素化アルキルアクリレートとを組み合わせると相溶性が極めて良好でかつ繊維に対し極めて良好な密着性を示すことを見出し、この知見に基いて本発明を完成したものである。 The water repellent composition for fibers according to the invention of claim 7 is such that the hydroxyl group-containing silicone oil is a hydroxyl group-containing polyalkylsiloxane and the fluororesin-based water repellent agent is a polyfluorinated alkyl acrylate. The inventors of the present invention have conducted extensive experimental research on a hydroxyl group-containing silicone oil as an appropriate binder resin in order to utilize a fluororesin-based water repellent, and as a result, when a hydroxyl group-containing polyalkylsiloxane and a polyfluorinated alkyl acrylate are combined. The present inventors have found that the compatibility is very good and that the fiber exhibits extremely good adhesion, and the present invention has been completed based on this finding.
ポリフッ素化アルキルアクリレートとしては、より具体的には、例えば（メタ）アクリル酸とアルキル基、アルキレン基の水素がフッ素原子で置換されたフッ素置換アルコールとのエステル、或いはエーテル結合を含むフッ素置換アルコールとのエステルの単独重合体または共重合体等を用いることができる。水酸基含有ポリアルキルシロキサンとポリフッ素化アルキルアクリレートとの混合物を加熱すると脱水反応が生じ、繊維製品上に柔軟な被膜が密着して形成され、かつ両樹脂の相溶性が良いので洗濯等の物理的な揉みに対しても充分に耐え得る耐久性良好な撥水性被膜を形成させることができる。 More specifically, examples of the polyfluorinated alkyl acrylate include, for example, (meth) acrylic acid and an alkyl group, an ester of a fluorine-substituted alcohol in which hydrogen of an alkylene group is substituted with a fluorine atom, or a fluorine-substituted alcohol containing an ether bond. Homopolymers or copolymers of esters with can be used. When a mixture of a hydroxyl group-containing polyalkylsiloxane and a polyfluorinated alkyl acrylate is heated, a dehydration reaction occurs, a flexible film is formed in close contact with the fiber product, and the compatibility of both resins is good, so that physical properties such as washing are performed. It is possible to form a water-repellent coating with good durability that can sufficiently withstand stagnation.

請求項８の発明にかかる繊維製品の撥水加工処理方法は、請求項５乃至請求項７のいずれか１つに記載した繊維用撥水剤組成物を繊維製品に対し通常の方法で含浸させ、乾燥後約１００℃〜約１３０℃で熱処理するものである。ここで、「繊維製品」としては、ポリエステル、ポリアミド、ポリウレタン、レーヨン、アセテート、木綿、絹、羊毛等の各種繊維（これらの混用繊維を含む）からなる織物、編物、不織布や和紙、洋紙、天然または人工皮革からなるシート状物、及び洋服や和服、レインコート、帽子、各種グッズ等がある。 The water repellent treatment method for a textile product according to the invention of claim 8 is characterized by impregnating the fiber product with the water repellent composition for fibers according to any one of claims 5 to 7 by a normal method.

It is possible to form a water-repellent coating with good durability that can sufficiently withstand physical stagnation such as washing.

Then, it is heat-treated at about 100 ° C. to about 130 ° C. after air drying. When a mixture of a hydroxyl group-containing polyalkylsiloxane and a polyfluorinated alkyl acrylate is heated, a dehydration reaction occurs, a flexible film is formed in close contact with the fiber product, and the compatibility of both resins is good, so that physical properties such as washing are performed.
