DESCRIPTION OF THE INVENTION
[0013]
　It will be described in detail embodiments of the present invention. Fabric of the present invention is a fabric comprising a spun yarn comprising meta-type aromatic polyamide fibers, luminosity index L value of the fabric is 25 or less (preferably 10 to 25).
[0014]
　Here, the meta-type wholly aromatic polyamide fibers are preferably optical absorptance of 1000 ~ 1500 nm contains an infrared-absorbing inorganic substance is 70% or more. Such infrared absorbing inorganic fine particles, carbon black is preferred, may be dark-colored pigment.
[0015]
　Such infrared absorbing inorganic substance is preferably contained in the polymer to form a meta-type wholly aromatic polyamide fibers in terms of durability, it may be attached to the fiber surface.
[0016]
　At that time, the content of the infrared absorbing inorganic substance is preferably a fiber weight versus 1% by weight or more (more preferably 2-9% by weight). The amount is less than 1 wt%, not lightness index L value is small, protective performance against electrical arcing may be reduced.
[0017]
　The polymer forming the meta-type wholly aromatic polyamide fibers, but in which the aromatic ring constituting the main skeleton is coupled to the meta by an amide bond, more than 85 mol% of all repeating units of the polymer is metaphenylene targeting what is isophthalamide units, in particular poly-m-phenylene isophthalamide homopolymer is preferred. 15 mol% of all the repeating units or less, as preferably the third component copolymerizable with 5 mol% or less, as the diamine component, such as para-phenylenediamine, 3,4'-diaminodiphenyl ether, 4,4'-diaminodiphenyl ether , p-xylylenediamine, biphenylene diamine, 3,3'-dichlorobenzidine, 3,3'-dimethyl benzidine, 3,4'-diaminodiphenylmethane, 4,4'-diaminodiphenylmethane, etc. 1,5-naphthalene diamine aromatic diamines, but also as an acid component, such as terephthalic acid, naphthalene-2,6-dicarboxylic acid, aromatic dicarboxylic acids such as naphthalene-2,7-dicarboxylic acid. These aromatic diamines and aromatic dicarboxylic acids, some of the hydrogen atoms of the aromatic ring may be substituted by an alkyl group such as a halogen atom or a methyl group. 20% or more of all the terminal of the polymer, if it is blocked with a monovalent diamine or the carboxylic acid component of the monovalent aniline or the like, lowering of strength of the fiber becomes smaller to hold particularly long time in a high-temperature since preferred. According to the meta-type wholly aromatic polyamide fibers, the functional properties may include flame retardants, ultraviolet absorbers and other functional agents to hold.
