【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、難燃性繊維構造物に関するものである。[Detailed description of the invention] [Industrial application field] FIELD OF THE INVENTION The present invention relates to flame-retardant fibrous structures.
従来、高温、高熱作業者、ガソリン等の揮発性物質取扱
者、ドライバー等に有用な火炎防護服や、航空機、電車
等の内装材は、難燃性繊維構造物が使用されている。こ
れらの難燃性繊維構造物が単に耐炎性であるだけでは十
分でなく、激しい熱流に対しても破れて穴があき、人体
もしくは、内部の可燃物体に炎が直接接触しないよう十
分な強度も保持しなければならない。Conventionally, flame-retardant fiber structures have been used in flame protective clothing useful for high-temperature workers, people who handle volatile substances such as gasoline, drivers, etc., and interior materials for aircraft, trains, etc. It is not enough for these flame-retardant fiber structures to simply be flame-resistant; they also have sufficient strength to prevent the flames from tearing and puncturing against intense heat flow, preventing direct contact with the human body or combustible objects inside. Must be retained.
又、−船釣に市場に受は入れやすい条件として、難燃性
繊維構造物は、耐炎性、可染性、耐久性であり、かつ軽
量なことが必要である。In order to be easily accepted in the boat fishing market, the flame-retardant fiber structure must be flame resistant, dyeable, durable, and lightweight.
この様な状況において、最近有機耐熱繊維か開発され、
たとえば芳香族ポリアミド繊維が用いられており耐熱性
、耐溶剤性、防炎性など数多くの利点を有しているため
高く評価されている。しかし、メタ系芳香族ポリアミド
繊維は、実際高温(例えば500°C又はそれ以上)の
物体に直接接触すると15%以上の収縮を起し、場合に
よっては、穴がおいてしまうこともある。一方パラ配向
芳香族ポリアミド繊維は、高温物体の直接接触によって
炭化し強力低下を起し、編織構造物の厚さにもよるが穴
あき現象がある。Under these circumstances, organic heat-resistant fibers have recently been developed.
For example, aromatic polyamide fibers are used and are highly evaluated because they have many advantages such as heat resistance, solvent resistance, and flame resistance. However, meta-aromatic polyamide fibers actually shrink by 15% or more when they come into direct contact with objects at high temperatures (for example, 500° C. or higher), and in some cases, may even form holes. On the other hand, para-oriented aromatic polyamide fibers are carbonized by direct contact with a high-temperature object, resulting in a decrease in strength, and depending on the thickness of the textile structure, there is a hole formation phenomenon.

木綿、レーヨンなどのような通常燃焼性のある繊維を各

。Also, although it has self-extinguishing properties when the burning object is removed,
Commonly combustible fibers such as cotton, rayon, etc. are treated with various flame resistant compositions.
更に、難燃性付与剤と共に紡糸した通常では易燃性繊維

。Additionally, normally flammable fibers spun with flame retardant agents, recycled or synthetic fibers such as rayon, polyester, acrylic, etc., or synthetics spun from inherently flame resistant polymeric materials such as vinyl chloride. Flame-resistant structures woven or woven from any of the fibers are commonly applied and evaluated in curtains, carpets, upholstery, etc., and bedding where the propagation of flame is to be avoided.
しかし、高温物体が火炎熱流にさらされるときに高度の
収縮と破損によって穴あきを示し満足なものとは言えな
い。However, when the hot object is exposed to the flame heat flow, it is unsatisfactory as it exhibits a high degree of shrinkage and puncture due to breakage.
従来の技術は、無機繊維素材、たとえばアスベスト、ガ

による繊維切断のため糸および布帛への加工が極めて困
難である。更に折れた繊維の突きささりにより着用者の
不快感や社会生態学的な理由による受は入れ難さが挙げ
られる。Conventional technology provides heat-resistant structures made of inorganic fiber materials such as asbestos, glass fiber, and ceramic fiber. Although they are useful in their respective functions, they are extremely difficult to process into threads and fabrics due to the non-dyeability and brittleness of the fibers, which cause the fibers to break due to bending. Furthermore, the sticking of the broken fibers causes discomfort to the wearer and is difficult to accept due to socio-ecological reasons.
一方、耐炎化繊維は、PAN (ポリアクリロニトリル
)系、ピッチ系、フェノール系繊維を原料とする炭素繊
維製造工程の中間体として得られることは公知である。On the other hand, it is known that flame-resistant fibers can be obtained as intermediates in the carbon fiber manufacturing process using PAN (polyacrylonitrile), pitch, and phenol fibers as raw materials.
耐炎化繊維は火炎熱流に対し耐炎性、自己消火性、耐溶
剤性など有用である。しかしながら強度、伸度共に低い
値を示し脆弱な繊維であるために耐摩耗性が劣り耐久性
に問題があった。Flame-resistant fibers are useful in terms of flame resistance, self-extinguishing properties, and solvent resistance against flame heat flow. However, since it is a brittle fiber with low values for both strength and elongation, it has poor abrasion resistance and has problems in durability.
本発明者らは、かかる技術的現状に鑑みこれらの素材を

しかも自己消火性のある難燃繊維が好のましい。The multilayer structure of the present invention is a structure composed of two or more layers of knitted fabrics, nonwoven fabrics, or nonwoven fabrics and knitted fabrics combined by needle punching or the like, and is preferably made of a composite material with high density and thickness. A thin woven fabric is preferred, and the surface layer is a flame-retardant fibrous structure made of flame-retardant and dyeable fibers. The flame-retardant fibers and dyeable fibers used for the surface mentioned here refer to LOI (lowest oxygen index JIS-7201, 1).
972) is 23 or more, preferably 25 or more. Examples include aromatic polyamide fibers, vinyl chloride, and those made of a copolymer mainly composed of a vinyl compound and acrylonitrile, but are not particularly limited ( , L
Any fiber that has an OI of 23 or more and is dyeable may be used. In particular, it does not burn up due to flame, has low heat conduction and chars,
Furthermore, flame-retardant fibers with self-extinguishing properties are preferred.

Flammability tests were conducted using LP gas. The evaluation method was to bring the flame into direct contact with the surface layer of the sample, and then measure the time during which burner flame was observed on the opposite side (the lining layer) of the sample. In addition, a flame was brought into contact with the surface layer of the sample for 2 minutes, and the breaking strength at the center of the sample was measured. The method is to fix the sample after combustion horizontally, place a 3.6g piece of stainless steel round rod with diameter 8φ x length 10mm in the center part where the flame touched, add a weight, and when the stainless steel piece falls. Evaluation was made using the weight of the weight. The results are shown in Table 1.
