本発明によれば、難燃性、耐薬品性、布帛強度、および軽量性に優れた布帛および繊維製品が得られる。 According to the present invention, a fabric and a textile product excellent in flame retardancy, chemical resistance, fabric strength, and light weight can be obtained.
以下、本発明の実施の形態について詳細に説明する。
本発明の布帛は、ポリベンゾイミダゾール繊維と共重合型芳香族ポリアミド繊維とを含む糸条を含む。
ここで、ポリベンゾイミダゾール繊維としてはＰＢＩアドバンストマテリアルズ社などから市販されている市販品でよい。
一方、共重合型芳香族ポリアミド繊維としては、ポリマー繰返し単位の８０モル％以上が下記式からなる芳香族コポリアミド（コポリパラフェニレン・３．４’オキシジフェニレンテレフタルアミド）で構成されることが好ましい。
Hereinafter, embodiments of the present invention will be described in detail.
The fabric of the present invention includes a yarn containing polybenzimidazole fiber and copolymerized aromatic polyamide fiber.
Here, the polybenzimidazole fiber may be a commercial product commercially available from PBI Advanced Materials.
On the other hand, as the copolymer type aromatic polyamide fiber, 80 mol% or more of the polymer repeating units may be composed of an aromatic copolyamide (copolyparaphenylene 3.4′oxydiphenylene terephthalamide) having the following formula. preferable.
かかるポリアミドには各種添加剤が含まれていてもよい。また、最大で１０重量％の量の他の高分子材料をポリアミドと混合すること、またはポリアミドを構成するジアミン成分の１０％を他のジアミン成分で置き換えるかもしくはポリアミドを構成するジ酸クロリド成分の１０％を他のジ酸クロリド成分で置き換えたコポリマーを使用することができる。 Such polyamide may contain various additives. Also, other polymer materials in an amount of up to 10% by weight are mixed with the polyamide, or 10% of the diamine component constituting the polyamide is replaced with another diamine component or the diacid chloride component constituting the polyamide. Copolymers with 10% replaced with other diacid chloride components can be used.
また、前記糸条を構成する繊維がポリベンゾイミダゾール繊維と共重合型芳香族ポリアミド繊維のみであることが好ましい。また、ポリベンゾイミダゾール繊維と共重合型芳香族ポリアミド繊維の重量比が（前者／後者）２０／８０〜８０／２０（より好ましくは３５／６５〜６５／３５）の範囲内であることが好ましい。ポリベンゾイミダゾール繊維の含有量が該範囲よりも小さいと、難燃性が低下するおそれがある。逆に、共重合型芳香族ポリアミド繊維の含有量が該範囲よりも小さいと、耐薬品性が低下するおそれがある。 Moreover, it is preferable that the fiber which comprises the said thread | yarn is only a polybenzimidazole fiber and a copolymerization type aromatic polyamide fiber. The weight ratio of the polybenzimidazole fiber and the copolymerized aromatic polyamide fiber is preferably in the range of (the former / the latter) 20/80 to 80/20 (more preferably 35/65 to 65/35). . If the content of the polybenzimidazole fiber is smaller than the above range, the flame retardancy may be lowered. On the contrary, when the content of the copolymer type aromatic polyamide fiber is smaller than the above range, the chemical resistance may be lowered.
前記糸条はマルチフィラメント（長繊維）でもよいが、難燃性と耐薬品性を両立させる上で紡績糸が好ましい。ポリベンゾイミダゾール繊維と共重合型芳香族ポリアミド繊維とを混紡して紡績糸とすることにより両繊維が混ざり合い難燃性と耐薬品性の両立が可能となる。なかでも、単繊維繊度１〜５ｄｔｅｘ、繊維長２５〜２００ｍｍのポリベンゾイミダゾール繊維からなる短繊維と、単繊維繊度１〜５ｄｔｅｘ、繊維長２５〜２００ｍｍの共重合型芳香族ポリアミド繊維からなる短繊維を用いた紡績糸が好ましい。
かかる紡績糸において、英式綿番手で１０〜３０の範囲内であることが好ましい。１０番よりも小さい（繊度が太い）場合、生地重量が増加し軽量性が損なわれるおそれがある。逆に３０番より大きい（繊度が細い）場合、布帛の引裂強さが低下するおそれがある。
The yarn may be a multifilament (long fiber), but a spun yarn is preferable for achieving both flame retardancy and chemical resistance. By blending a polybenzimidazole fiber and a copolymerized aromatic polyamide fiber into a spun yarn, both fibers can be mixed to achieve both flame retardancy and chemical resistance. Among them, a short fiber made of polybenzimidazole fiber having a single fiber fineness of 1 to 5 dtex and a fiber length of 25 to 200 mm, and a short fiber made of copolymerized aromatic polyamide fiber having a single fiber fineness of 1 to 5 dtex and a fiber length of 25 to 200 mm. A spun yarn using is preferably used.
In such a spun yarn, it is preferable that it is in the range of 10 to 30 in English cotton count. If it is smaller than 10 (thickness is thick), the weight of the fabric may increase and the lightness may be impaired. Conversely, if it is larger than 30 (fineness is thin), the tear strength of the fabric may be reduced.
特に、前記糸条に撚り係数５〜１１の範囲内で撚りがかけられていると、難燃性と耐薬品性と布帛強度が向上し好ましい。
撚り係数＝Ｔ／√ｎ
ただし、Ｔは２．５４ｃｍあたりの総撚数であり、ｎは英式綿番手である。総撚数とは、例えば下撚数＋上撚数を意味する。
撚り係数が５よりも小さいと布帛において十分な引裂強さを得られないおそれがある。逆に、撚り係数が１１よりも大きいと、解撚トルクのため製織工程が困難になるおそれがある。
In particular, it is preferable that the yarn is twisted within a range of a twist coefficient of 5 to 11 because flame retardancy, chemical resistance, and fabric strength are improved.
Twist factor = T / √n
However, T is the total number of twists per 2.54 cm, and n is an English cotton count. The total number of twists means, for example, the number of lower twists + the number of upper twists.
When the twist coefficient is less than 5, there is a possibility that sufficient tear strength cannot be obtained in the fabric. On the contrary, if the twist coefficient is larger than 11, the weaving process may be difficult due to the untwisting torque.
前記紡績糸の製造方法は公知の方法でよく、例えば、リング精紡、コア精紡およびエアジェット精紡、空気を用いてステープル繊維を撚糸する村田エアジェット精紡のような高次エア精紡技術等、公知の精紡技術により製造してよい。
本発明の布帛において、布帛の組織は限定されず織物、編物、不織布いずれでもよいが、優れた布帛強度を得る上で織物が好ましい。その際、織物が平織組織または綾織組織または朱子織組織を有することが好ましい。
The spun yarn may be produced by a known method, such as ring spinning, core spinning, air jet spinning, and higher air spinning such as Murata Air Jet spinning, in which staple fibers are twisted using air. You may manufacture by well-known spinning techniques, such as a technique.
In the cloth of the present invention, the structure of the cloth is not limited, and any of a woven fabric, a knitted fabric, and a non-woven fabric may be used, but a woven fabric is preferable in order to obtain excellent fabric strength. In that case, it is preferable that the woven fabric has a plain weave texture, a twill texture or a satin texture.
また、織物に前記糸条とは異なる糸条（「第２の糸条」と称す。）が含まれ、かかる第２の糸条が経糸および緯糸に格子状に織り込まれていることが好ましい。かかる組織はリップストップ組織とも称される。
その際、経方向および／または緯方向に互いに隣り合う第２の糸条同士の間隔は、２〜１５ｍｍ（より好ましくは３〜８ｍｍ）の範囲内であることが好ましい。
Further, it is preferable that the woven fabric includes a yarn different from the yarn (referred to as a “second yarn”), and the second yarn is woven into a warp and a weft in a lattice shape. Such a structure is also called a ripstop structure.
At that time, the interval between the second yarns adjacent to each other in the warp direction and / or the weft direction is preferably in the range of 2 to 15 mm (more preferably 3 to 8 mm).
前記第２の糸条を構成する繊維としては、メタ系芳香族ポリアミド繊維、パラ型芳香族ポリアミド繊維、導電性繊維、ポリエステル繊維、ナイロン繊維、アクリル繊維、アクリレート系繊維、難燃レーヨン繊維、難燃ビニロン繊維などが例示される。
前記第２の糸条はマルチフィラメント（長繊維）でもよいし紡績糸でもよい。
本発明の布帛において、布帛の製造方法は特に限定されず、レピア織機やグリッパー織機など公知の織編機を用いることができる。

The second yarn may be a multifilament (long fiber) or a spun yarn.
In the fabric of the present invention, the method for producing the fabric is not particularly limited, and a known knitting machine such as a rapier loom or a gripper loom can be used.
本発明の布帛において、目付けが１５０〜３００ｇ／ｃｍ２（より好ましくは１７０〜２５０ｇ／ｃｍ２）の範囲内であることが好ましい。目付けが該範囲よりも小さい場合は、難燃性、引裂強さが低下するおそれがある。逆に、目付けが該範囲よりも大きい場合は、重量が重くなり軽量性が損なわれるおそれがある。 In the fabric of the present invention, the basis weight is preferably in the range of 150 to 300 g / cm 2 (more preferably 170 to 250 g / cm 2 ). If the basis weight is smaller than this range, the flame retardancy and tear strength may be reduced. On the other hand, when the basis weight is larger than the above range, the weight becomes heavy and the lightness may be impaired.
本発明の布帛において、染色加工だけでなく、吸汗剤、撥水剤、蓄熱剤、紫外線遮蔽あるいは制電剤、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤等の機能を付与する他の各種加工を付加適用してもよい。
