Abstract
Description
本発明は深色性、吸水性に優れ、かつ洗濯耐久性、抗フロスティング性を有し、家庭でのウオッシャブル対応が可能な衣料用途の織物または編物（織編物）に関し、さらに好ましくはブラックフォーマル用途の織編物に関する。 The present invention relates to a woven fabric or knitted fabric (woven / knitted fabric) that is excellent in deep color and water absorbability, has washing durability and anti-frosting properties and can be washed at home, and more preferably black formal It relates to woven and knitted fabrics.
ブラックフォーマル用途の織編物として、従来よりポリエステル系繊維などの合成繊維は優れた物理的特性および化学的特性を有しているため広く使用されている。しかし、ウール、絹などの天然繊維、レーヨン、アセテートなどの半合成繊維に比べ、鮮明性、濃色の深み、発色性が劣るという欠点があり、このため、従来から繊維表面にフッ素系樹脂、シリコン系樹脂などの低屈折率樹脂を繊維表面に付着させ深色性を高める提案がなされている。しかしながら、これらの提案は、深色性の向上は得られるもののこれらの処理剤は撥水性を有するため、汗ばむ季節の着用においては、肌へのベタツキ等により着用快適性が不十分であった。 Synthetic fibers such as polyester fibers have been widely used as woven and knitted fabrics for black formal applications because they have excellent physical and chemical properties. However, compared to natural fibers such as wool and silk, and semi-synthetic fibers such as rayon and acetate, there are disadvantages of being inferior in sharpness, deep color, and color development. Proposals have been made to improve the deep color by attaching a low refractive index resin such as a silicone resin to the fiber surface. However, although these proposals can improve the deep color, these treatment agents have water repellency. Therefore, the wearing comfort is insufficient due to the stickiness on the skin and the like in the sweaty season.
また、着用後のクリーニング性は一般家庭での洗濯対応の要望が高く、家庭洗濯後においても耐久性のある優れた深色性、吸水性のある素材が求められている。 Further, the cleaning property after wearing is highly demanded for washing in general households, and there is a demand for a material with excellent deep color and water absorption that is durable even after home washing.
耐久性に優れた深色特性を有するものとして、例えば、特許文献１には、アクリル酸エステル共重合体を介して、フッ素系化合物およびシリコン系化合物を主体とする屈折率１．５以下の重合皮膜を有する方法が提案されている。しかし、家庭洗濯での耐久性のある深色性は得られるもののフッ素系樹脂、シリコン系化合物を使用するため、撥水性を有してはいるものの、吸水性は得られていない。 For example, Patent Document 1 discloses a polymer having a refractive index of 1.5 or less mainly composed of a fluorine-based compound and a silicon-based compound via an acrylic ester copolymer as one having deep color characteristics excellent in durability. A method having a coating has been proposed. However, although a durable deep color property can be obtained in home laundry, a fluororesin and a silicon compound are used, so that although it has water repellency, water absorption is not obtained.
また、深色性、吸水性を有するものとして、例えば、特許文献２には、繊維より屈折率の低い低屈折率樹脂、親水性樹脂、セラミック微粒子を含む樹脂加工液で繊維表面に付着する方法が提案されている。また、特許文献３には、シランカップリング剤で処理したシリカ微粒子とポリエーテル変性ポリシキロキサンを含有する吸水性を有する深色剤、処理方法が提案されている。しかしながら、深色性を得るためにシリカ系微粒子が樹脂液中に使用されるため、抗フロスティング性が不十分となり、縫製時、着用時の生地の擦れ等に白化問題が抑えきれない可能性があった。また、初期、ドライクリーニング後に対する深色性、吸水性の耐久性は得られているが、家庭洗濯後の深色性、吸水性については不十分の可能性があった。 Moreover, as what has deep color property and water absorption, for example, Patent Document 2 discloses a method of adhering to a fiber surface with a resin processing liquid containing a low refractive index resin having a lower refractive index than that of a fiber, a hydrophilic resin, and ceramic fine particles. Has been proposed. Patent Document 3 proposes a deep colorant having a water absorption and a treatment method containing silica fine particles treated with a silane coupling agent and a polyether-modified polysiloxane. However, since silica-based fine particles are used in the resin solution to obtain deep color, anti-frosting properties may be insufficient, and whitening problems may not be suppressed due to rubbing of the fabric during sewing and wearing. was there. In addition, the durability of the deep color and water absorption after the initial and dry cleaning have been obtained, but the deep color after home washing and the water absorption may be insufficient.
本発明の課題は、かかる従来技術の背景に鑑み、深色性、吸水性に優れ、かつ洗濯耐久性、抗フロスティング性に有し、家庭でのウオッシャブル対応が可能な衣料用途の織編物およびその製造方法を提供することにある。 In view of the background of the prior art, the object of the present invention is to provide a woven or knitted fabric for apparel that is excellent in deep color and water absorption, has washing durability and anti-frosting properties, and is capable of being washed at home.
