Description
本発明は、難燃性、耐光性、耐摩耗性だけでなく、火炎または熱によって暴露された際に優れた強度を兼ね備えた布帛および繊維製品に関する。 The present invention relates to fabrics and textile products that combine flame retardancy, light resistance, and abrasion resistance as well as excellent strength when exposed to flame or heat.
従来、消防服などの防護服に用いられる布帛として種々の布帛が提案されている。しかしながら、これらの布帛は消防活動中に火炎や熱に一度でも暴露されると、その暴露を受けた部位が硬化、炭化して脆化してしまい、防護機能を著しく損ねるといった問題を有している。 Traditionally, various fabrics have been proposed for use in protective clothing such as firefighting suits. However, these fabrics have the problem that if they are exposed to flames or heat even once during firefighting activities, the exposed areas harden, carbonize, and become brittle, significantly impairing their protective function.
かかる問題を解決するため、例えば特許文献１では、耐熱性、軽量性、耐候性、および火炎暴露炭化後の布帛柔軟性を兼ね備えた布帛が提案されているが、熱暴露後の強度についてまだ十分とはいえなかった。 To solve these problems, for example, Patent Document 1 proposes a fabric that combines heat resistance, light weight, weather resistance, and fabric flexibility after flame exposure and carbonization, but the strength after heat exposure is still insufficient.
本発明は上記の背景に鑑みなされたものであり、その目的は、難燃性、耐光性、耐摩耗性だけでなく、さらには火炎または熱によって暴露された際に優れた強度をも有する布帛および繊維製品を提供することにある。 The present invention has been made in view of the above background, and its object is to provide fabrics and textile products that are not only flame retardant, light resistant, and abrasion resistant, but also have excellent strength when exposed to flame or heat.
本発明者らは上記の課題を達成するため鋭意検討した結果、布帛を構成する繊維種類などを巧みに工夫することにより難燃性だけでなく、耐光性、耐摩耗性、さらには火炎または熱によって暴露された際に優れた強度をも有する布帛が得られることを見出し、さらに鋭意検討を重ねることにより本発明を完成するに至った。 As a result of extensive research into achieving the above object, the inventors discovered that by skillfully adjusting the type of fibers that make up the fabric, it is possible to obtain a fabric that is not only flame retardant, but also light-resistant, abrasion-resistant, and has excellent strength when exposed to flame or heat. Further extensive research led to the completion of the present invention.
かくして、本発明によれば「全芳香族ポリアミド繊維とポリベンズオキサゾール繊維とをこの順の混合率（重量比）で１００／０～８０／２０で含む糸１と、ポリベンズオキサゾール繊維を糸重量に対し３０重量％以上含む糸２を含むことを特徴とする布帛。」が提供される。 Thus, the present invention provides a fabric comprising yarn 1 containing wholly aromatic polyamide fiber and polybenzoxazole fiber in a mixing ratio (weight ratio) of 100/0 to 80/20 in that order, and yarn 2 containing 30% or more by weight of polybenzoxazole fiber relative to the weight of the yarn.
その際、前記糸１が、ポリベンズイミダゾール繊維、酸化ポリアクリロニトリル繊維、難燃アクリル繊維、難燃レーヨン繊維、および難燃ポリエステル繊維の群から選択されるいずれかの繊維をさらに含むことが好ましい。また、前記糸２が、メタ型全芳香族ポリアミド繊維、パラ型全芳香族ポリアミド繊維、ポリベンズイミダゾール繊維、酸化ポリアクリロニトリル繊維、難燃アクリル繊維、難燃レーヨン繊維、および難燃ポリエステル繊維の群から選択されるいずれかの繊維をさらに含むことが好ましい。また、前記糸２が多層構造紡績糸であって、芯成分が牽切紡績されたポリベンズオキサゾール繊維を含み、鞘成分が全芳香族ポリアミド繊維を含むことが好ましい。 In this case, it is preferable that the yarn 1 further contains any fiber selected from the group consisting of polybenzimidazole fiber, oxidized polyacrylonitrile fiber, flame-retardant acrylic fiber, flame-retardant rayon fiber, and flame-retardant polyester fiber. It is also preferable that the yarn 2 further contains any fiber selected from the group consisting of meta-type wholly aromatic polyamide fiber, para-type wholly aromatic polyamide fiber, polybenzimidazole fiber, oxidized polyacrylonitrile fiber, flame-retardant acrylic fiber, flame-retardant rayon fiber, and flame-retardant polyester fiber. It is also preferable that the yarn 2 is a multilayer spun yarn, the core component contains stretch-break spun polybenzoxazole fiber, and the sheath component contains wholly aromatic polyamide fiber.
本発明の布帛において、布帛が部分二重織物であり、前記糸２が経および緯に格子状に織り込まれており、かつ織物の経糸および／または緯糸において糸１と糸２が１：１～１５：１の割合で配されていることが好ましい。また、布帛の表面または裏面において、糸１の露出割合が７０％以上であることが好ましい。また、ＩＳＯ１７４９２で規定される試験装置を用いて熱流束８４ｋＷ／ｍ２の火炎で１０秒間暴露した後の引張強度保持率が１０％以上であることが好ましい。また、スーパーキセノンウエザーメーターを用いて、その紫外線照射面を変更することなく、ＵＶ照射強度：１８０Ｗ／ｍ２、ブラックパネル温度：６３℃、降雨なしの条件で３５０時間照射処理した後の引張強度保持率が２０％以上であることが好ましい。また、ＩＳＯ１２９４７－２（マーチンデール）に規定される摩耗試験において、生地が破れるまでの回数が２００００回以上であることが好ましい。 In the fabric of the present invention, it is preferable that the fabric is a partially double woven fabric, the yarn 2 is woven in a lattice pattern in the warp and weft, and the yarn 1 and the yarn 2 are arranged in a ratio of 1:1 to 15:1 in the warp and/or weft of the fabric. It is also preferable that the exposed ratio of the yarn 1 is 70% or more on the front or back of the fabric. It is also preferable that the tensile strength retention rate after exposure to a flame with a heat flux of 84 kW/m 2 for 10 seconds using a test device specified in ISO17492 is 10% or more. It is also preferable that the tensile strength retention rate after irradiation treatment for 350 hours using a super xenon weather meter under conditions of UV irradiation intensity: 180 W/m 2 , black panel temperature: 63°C, and no rainfall without changing the ultraviolet irradiation surface is 20% or more. It is also preferable that the number of times until the fabric breaks is 20,000 or more in the abrasion test specified in ISO12947-2 (Martindale).
また、本発明によれば、前記の布帛を用いてなる、防護服、消防防火服、消防活動服、救助服、ワークウェア、警察制服、自衛隊衣服、および軍服からなる群より選択されるいずれかの繊維製品が提供される。 The present invention also provides a textile product made from the above-mentioned fabric, selected from the group consisting of protective clothing, fire-retardant clothing, firefighting clothing, rescue clothing, workwear, police uniforms, Self-Defense Force clothing, and military uniforms.
本発明によれば、難燃性、耐光性、耐摩耗性だけでなく、火炎または熱によって暴露された際に優れた強度をも有する布帛および繊維製品が得られる。 The present invention provides fabrics and textile products that are not only flame retardant, light resistant, and abrasion resistant, but also have excellent strength when exposed to flame or heat.
以下、本発明の実施の形態について詳細に説明する。まず、本発明の布帛は、糸１として、全芳香族ポリアミド繊維とポリベンズオキサゾール繊維とをこの順の混合率（重量比）で１００／０～８０／２０で含む。ポリベンズオキサゾール繊維の混合率の重量比が該範囲を超えると、耐摩耗性と初期の熱暴露後強度が向上するものの、耐光性が低下するため、布帛が日光に晒された後の熱・火炎に対する防護性能を失うおそれがあり好ましくない。 The following is a detailed description of an embodiment of the present invention. First, the fabric of the present invention contains, as yarn 1, a wholly aromatic polyamide fiber and a polybenzoxazole fiber in a mixing ratio (weight ratio) of 100/0 to 80/20 in that order. If the weight ratio of the polybenzoxazole fiber mixing ratio exceeds this range, although the abrasion resistance and strength after initial heat exposure are improved, the light resistance is reduced, and there is a risk that the fabric will lose its protective performance against heat and flames after exposure to sunlight, which is not preferable.
ここで、前記全芳香族ポリアミド繊維としては、メタ型全芳香族ポリアミド繊維やパラ型全芳香族ポリアミド繊維を挙げることができる。その際、メタ型全芳香族ポリアミド繊維は、その繰返し単位の８５モル％以上がｍ－フェニレンイソフタルアミドであるポリマーからなる繊維である。市販品では「コーネックス」（商標名）などが例示される。パラ型全芳香族ポリアミド繊維は、パラフェニレンテレフタラミド繊維またはコパラフェニレン・３、４’オキシジフェニレンテレフタルアミド繊維が好ましく、市販品では「トワロン」（商標名）、「テクノーラ」（商標名）などが例示される。また、ポリベンズオキサゾール繊維は、市販品では「ザイロン」（商標名）などが例示される。 The fully aromatic polyamide fibers may be meta-type fully aromatic polyamide fibers or para-type fully aromatic polyamide fibers. In this case, meta-type fully aromatic polyamide fibers are fibers made of a polymer in which 85 mol% or more of the repeating units are m-phenylene isophthalamide. Commercially available products include "Conex" (trade name). Para-type fully aromatic polyamide fibers are preferably paraphenylene terephthalamide fibers or coparaphenylene-3,4'-oxydiphenylene terephthalamide fibers, and commercially available products include "Twaron" (trade name) and "Technora" (trade name). Commercially available polybenzoxazole fibers include "Zylon" (trade name).
前記糸１は、全芳香族ポリアミド繊維とポリベンザゾール繊維のみで構成されていてもよいし他の繊維を含んでいてもよい。その際、他の繊維としては、ポリベンズイミダゾール繊維、酸化ポリアクリロニトリル繊維、難燃アクリル繊維、難燃レーヨン繊維、難燃ポリエステル繊維などがあげられる。 The yarn 1 may be composed of only fully aromatic polyamide fibers and polybenzazole fibers, or may contain other fibers. In this case, the other fibers may include polybenzimidazole fibers, oxidized polyacrylonitrile fibers, flame-retardant acrylic fibers, flame-retardant rayon fibers, flame-retardant polyester fibers, etc.
また、本発明の布帛は、前記糸１だけでなく、ポリベンズオキサゾール繊維を糸重量に対し３０重量％以上含む糸２をも含む。ここで、糸２において、ポリベンズオキサゾール繊維の含有量が３０重量％未満の場合は、布帛が日光に晒された後の熱暴露後強度を保持できないおそれがある。 The fabric of the present invention includes not only the yarn 1, but also yarn 2 containing 30% or more by weight of polybenzoxazole fiber relative to the weight of the yarn. Here, if the content of polybenzoxazole fiber in yarn 2 is less than 30% by weight, the fabric may not be able to retain its strength after exposure to heat after exposure to sunlight.
前記糸２はポリベンズオキサゾール繊維のみで構成されていてもよいし他の繊維を含んでいてもよい。その際、他の繊維としては、メタ型全芳香族ポリアミド繊維、パラ型全芳香族ポリアミド繊維、ポリベンズイミダゾール繊維、酸化ポリアクリロニトリル繊維、難燃アクリル繊維、難燃レーヨン繊維、難燃ポリエステル繊維などがあげられる。
また、前記糸２が多層構造紡績糸であって、芯成分が牽切紡績されたポリベンズオキサゾール繊維を含み、鞘成分が全芳香族ポリアミド繊維を含むことが好ましい。
The yarn 2 may be composed of only polybenzoxazole fibers or may contain other fibers such as meta-type wholly aromatic polyamide fibers, para-type wholly aromatic polyamide fibers, polybenzimidazole fibers, oxidized polyacrylonitrile fibers, flame-retardant acrylic fibers, flame-retardant rayon fibers, and flame-retardant polyester fibers.
It is also preferable that the yarn 2 is a multi-layered spun yarn, the core component of which contains stretch-break spun polybenzoxazole fiber, and the sheath component of which contains wholly aromatic polyamide fiber.
本発明において、布帛の組織は限定されず、織物、編物いずれでもよく、前記糸１および糸２を用いて、常法により製織または製編することにより得られる。その際、糸１および糸２を交織または交編することが好ましい。 In the present invention, the structure of the fabric is not limited, and it may be either woven or knitted, and is obtained by weaving or knitting the yarn 1 and yarn 2 in a conventional manner. In this case, it is preferable to interweave or interknit yarn 1 and yarn 2.
特に、火炎または熱によって暴露された際の強度を高める上で、また日光に晒された時の耐光性を高める上で、布帛の表面（使用の際に外気側に位置する面）または裏面において、糸１の露出割合が７０％以上であることが好ましい。特に表面において、糸１の露出割合が７０％以上であることが好ましい。また、布帛が織物であり、前記糸２が経および緯に格子状に織り込まれており、かつ織物の経糸および／または緯糸において糸１と糸２とがこの順に１：１～１５：１（より好ましくは２：１～１０：１）の割合で配されていることが好ましい。 In particular, in order to increase the strength when exposed to flame or heat, and to increase the light resistance when exposed to sunlight, it is preferable that the exposed ratio of thread 1 is 70% or more on the front surface (the surface facing the outside air when in use) or back surface of the fabric. In particular, it is preferable that the exposed ratio of thread 1 is 70% or more on the front surface. It is also preferable that the fabric is a woven fabric, that thread 2 is woven in a lattice pattern in the warp and weft, and that thread 1 and thread 2 are arranged in this order in a ratio of 1:1 to 15:1 (more preferably 2:1 to 10:1) in the warp and/or weft of the fabric.
かくして得られた布帛は、難燃性だけでなく、耐光性、耐摩耗性、火炎または熱によって暴露された際に優れた強度をも有する。かかる強度保持率としては、ＩＳＯ１７４９２で規定される試験装置を用いて熱流束８４ｋＷ／ｍ２の火炎で１０秒間暴露した後、ＩＳＯ１３９３４－１に規定される引張試験を行って、経方向および／または緯方向において１０％以上であることが好ましい。また、スーパーキセノンウエザーメーターを用いて、その紫外線照射面を変更することなく、ＵＶ照射強度：１８０Ｗ／ｍ２、ブラックパネル温度：６３℃、降雨なしの条件で３５０時間照射処理した後の引張強度保持率が２０％以上であることが好ましい。また、ＩＳＯ１２９４７－２（マーチンデール）に規定される摩耗試験において、生地が破れるまでの回数が２００００回以上であることが好ましい。 The thus obtained fabric has not only flame retardancy, but also light resistance, abrasion resistance, and excellent strength when exposed to flame or heat. The strength retention is preferably 10% or more in the warp and/or weft directions when exposed to a flame with a heat flux of 84 kW/m 2 for 10 seconds using a test device specified in ISO 17492, and then a tensile test specified in ISO 13934-1 is performed. In addition, the tensile strength retention is preferably 20% or more after 350 hours of irradiation treatment using a super xenon weather meter under conditions of UV irradiation intensity: 180 W/m 2 , black panel temperature: 63°C, and no rainfall without changing the ultraviolet irradiation surface. In addition, in the abrasion test specified in ISO 12947-2 (Martindale), it is preferable that the number of times until the fabric breaks is 20,000 or more.
次に、本発明の繊維製品は、前記の布帛を用いてなる、防護服、消防防火服、消防活動服、救助服、ワークウェア、警察制服、自衛隊衣服、および軍服からなる群より選択されるいずれかの繊維製品である。かかる繊維製品は前記の布帛を用いているので、難燃性だけでなく、耐光性、耐摩耗性、火炎または熱によって暴露された際に優れた強度をも有する。 Next, the textile product of the present invention is any textile product selected from the group consisting of protective clothing, firefighting clothing, firefighting clothing, rescue clothing, workwear, police uniforms, Self-Defense Force clothing, and military uniforms, which uses the above-mentioned fabric. Since such textile products use the above-mentioned fabric, they are not only flame-retardant, but also have excellent light resistance, abrasion resistance, and strength when exposed to flame or heat.
次に本発明の実施例および比較例を詳述するが、本発明はこれらによって限定されるものではない。 Next, examples and comparative examples of the present invention will be described in detail, but the present invention is not limited to these.
