It has been proposed (see, for example, Patent Document 3).
　しかしながら、これらの布帛は、ストレッチ性の点で十分ではないという問題があった。 However, these fabrics have a problem that they are not sufficient in terms of stretchability.

　以下、本発明の実施の形態について詳細に説明する。本発明の撥水性布帛は、撥水加工を施してなる撥水性布帛であって、該布帛は複合糸を含み、該複合糸は、単繊維繊度１ｄｔｅｘ以下（より好ましくは０．００００２～０．８ｄｔｅｘ、特に好ましくは０．００１～０．５ｄｔｅｘ）の極細繊維と、伸縮性繊維とを含む。かかる構成により、前記極細繊維からなる微細繊維ループが布帛表面に形成されることにより布帛表面に蓮の葉状の微細な凹凸が形成され、優れた撥水性が得られる。また同時に、伸縮繊維の効果により布帛がストレッチ性にも優れる。ここで、前記極細繊維の単繊維繊度が１ｄｔｅｘよりも大きいと微細繊維ループが形成されず好ましくない。また、微細繊維ループを形成する上でかかる極細繊維は非捲縮繊維であることが好ましい。例えば、かかる極細繊維が仮撚捲縮加工糸であると、微細繊維ループが形成されないおそれがある。 Hereinafter, embodiments of the present invention will be described in detail. The water-repellent fabric of the present invention is a water-repellent fabric that has been subjected to a water-repellent treatment, and the fabric contains a composite yarn, and the composite yarn has a single fiber fineness of 1 dtex or less (more preferably 0.00002 to 0. It contains 8 dtex, particularly preferably 0.001 to 0.5 dtex) of ultrafine fibers and elastic fibers. With this configuration, the fine fiber loops made of the ultrafine fibers are formed on the surface of the cloth, so that fine irregularities like lotus leaves are formed on the surface of the cloth, and excellent water repellency can be obtained. At the same time, the fabric is also excellent in stretchability due to the effect of the elastic fibers. Here, if the single fiber fineness of the ultrafine fibers is larger than 1 dtex, fine fiber loops are not formed, which is not preferable. Further, the ultrafine fibers used to form the fine fiber loops are preferably non-crimped fibers. For example, if the ultrafine fibers are false twisted crimped yarns, fine fiber loops may not be formed.
　前記極細繊維としては、ポリエステル繊維、アクリル繊維、ナイロン繊維、レーヨン繊維、アセテート繊維、さらには、綿、ウール、絹などの天然繊維やこれらを複合したものが使用可能である。ポリエステル繊維は、少なくとも１成分としてポリエステル成分を含む複合繊維を含む。その際、複合繊維としては、サイドバイサイド型複合繊維、偏心芯鞘型複合繊維、芯鞘型複合繊維、海島型複合繊維などが例示される。また、ナイロン繊維は、ナイロン６繊維やナイロン６６繊維を含む。 As the ultrafine fibers, polyester fibers, acrylic fibers, nylon fibers, rayon fibers, acetate fibers, natural fibers such as cotton, wool and silk, and composites thereof can be used. The polyester fiber contains a composite fiber containing a polyester component as at least one component. At that time, examples of the composite fiber include a side-by-side type composite fiber, an eccentric core-sheath type composite fiber, a core-sheath type composite fiber, and a sea-island type composite fiber. The nylon fiber includes nylon 6 fiber and nylon 66 fiber.
　ポリエステル繊維を形成するポリエステルとしては、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、すなわ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より選ばれた少なくとも１種を主たるグリコール成分とするポリエステルが好ましい。なかでも、エ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（ポリエチレンテレフタレート）またはトリ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（ポリトリメチレンテレフタレート）が特に好ましい。 The polyester forming the polyester fiber is selected from the group consisting of terephthalic acid as a 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. A polyester containing at least one of these as a main glycol component is preferable. Of these, polyester containing ethylene glycol as a main glycol component (polyethylene terephthalate) or polyester containing trimethylene glycol as a main glycol component (polytrimethylene terephthalate) is particularly preferable.
　かかるポリエステルには、必要に応じて少量（通常３０モル％以下）の共重合成分を有していてもよい。その際、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、ナフタリンジカルボン酸、ジフェニルジカルボン酸、ジフェノキシエタンジカルボン酸、β－ヒドロキシエトキシ安息香酸、Ｐ－オキシ安息香酸、５－ナトリウムスルホイソフタル酸、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ごとき芳香族、脂肪族、脂環族の二官能性カルボン酸をあげることができる。また、上記グリコール以外のジオール化合物としては、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およびポリオキシアルキレングリコール等をあげることができる。 Such polyester may have a small amount (usually 30 mol% or less) of a copolymerization component, if necessary. At that time, examples of the bifunctional carboxylic acid other than the terephthalic acid used include isophthalic acid, naphthalindicarboxylic acid, diphenyldicarboxylic acid, diphenoxyetanedicarboxylic acid, β-hydroxyethoxybenzoic acid, P-oxybenzoic acid, and 5 -Aromatic, aliphatic and alicyclic bifunctional carboxylic acids such as sodium sulfoisophthalic acid, adipic acid, sebacic acid and 1,4-cyclohexanedicarboxylic acid can be mentioned.
