Abstract
The invention addresses the problem of providing a cloth that is excellent not only in flame retardancy and antistatic properties but also in appearance quality and preferably also has protection performance against electric arcs, a method for producing the same, and a textile product. A means for resolution is a cloth including a meta-type wholly aromatic polyamide fiber and an electrically conductive fiber, wherein both the meta-type wholly aromatic polyamide fiber and the electrically conductive fiber are colored.
Claims20
A flame-retardant and antistatic cloth, comprising:
- a meta-type wholly aromatic polyamide fiber, an electrically conductive acrylic fiber, and an additional fiber being at least one selected from the group consisting of para-type wholly aromatic polyamide fibers, polyphenylene sulfide fibers, polyimide fibers, polybenzimidazole fibers, polybenzoxazole fibers, polyamideimide fibers, polyetherimide fibers, and carbon fibers;
- wherein the meta-type wholly polyamide fiber and the electrically conductive fiber are contained in the form of a blend-spun yarn, wherein the meta-type wholly aromatic polyamide fiber is within the range from 80 to less than 99 mass % relative to the cloth mass;
- wherein the electrically conductive acrylic fiber is a sheath-core conjugate fiber including a core part containing electrically conductive carbon microparticles and a sheath part not containing any electrically conductive microparticles, wherein the electrically conductive acrylic fiber is within the range of greater than 1 to less than 20 mass % relative to the cloth mass;
- wherein both the meta-type wholly aromatic polyamide fiber and the electrically conductive acrylic fiber are colored using the same cationic dye, such that a hue difference between the meta-type wholly aromatic polyamide fiber and the electrically conductive acrylic fiber is ΔE 3 or less,
- wherein the cloth comprises an ATPV value in Arc Resistance Test ASTM F1959-1999 of 8.0 cal/cm2 or more, a frictional charge quantity of 7.0 μC/m2 as measured by a JS L1094-2014, C method, and an afterflame time of 1.0 second or less in a flammability measurement according to JIS L1091-1992,A-4 Method (12-second flame application).
