Abstract
In order to provide a fabric and a fiber product, which have hygroscopicity and durability as well as flame retardancy, a hydrophilizing agent is added to a fabric containing aramid fibers.
Claims
exact text as granted — not AI-modified1 . A fabric comprising aramid fibers, wherein the fabric is imparted with a hydrophilizing agent.
2 . The fabric according to claim 1 , wherein the aramid fibers comprise 30% by weight to 97% by weight of meta-aramid fibers and 3% by weight to 70% by weight of para-aramid fibers.
3 . The fabric according to claim 2 , wherein the degree of crystallization of the meta-type wholly aromatic polyamide fibers is within the range of 15% to 25%.
4 . The fabric according to claim 2 , wherein the meta-type wholly aromatic polyamide that forms the meta-type wholly aromatic polyamide fibers is a meta-type wholly aromatic polyamide obtained by copolymerizing an aromatic diamine component or an aromatic dicarboxylic acid halide component in an aromatic polyamide backbone containing a repeating structural unit represented by the following formula (1), the aromatic diamine component or the aromatic dicarboxylic acid halide component having different primary constituent units in the repeating structures thereof, such that it is copolymerized as a third component at 1 mol % to 10 mol % based on the total amount of repeating structural units of the aromatic polyamide:
—(NH—Ar1-NH—CO—Ar1-CO)— (1)
wherein, Ar1 represents a divalent aromatic group having a linking group in the meta coordination or in a coordination other than the parallel axis.
5 . The fabric according to claim 4 , wherein the aromatic diamine serving as a third component is represented by formula (2) or formula (3) and the aromatic dicarboxylic acid halide is represented by formula (4) or formula (5):
H 2 N—Ar2-NH 2 (2)
H 2 N—Ar2-Y—Ar2-NH 2 (3)
XOC—Ar3-COX (4)
XOC—Ar3-Y—Ar3-COX (5)
(wherein, Ar2 represents a divalent aromatic group different from Ar1, Ar3 represents a divalent aromatic group different from Ar1, Y represents at least one type of atom or functional group selected from the group consisting of an oxygen atom, sulfur atom and alkylene group, and X represents a halogen atom).
6 . The fabric according to claim 2 , wherein the residual amount of solvent in the meta-type aromatic polyamide fibers is 0.1% by weight or less.
7 . The fabric according to claim 1 , further containing electrically conductive fibers.
8 . The fabric according to claim 1 , further containing polyester fibers.
9 . The fabric according to claim 8 , wherein the polyester fibers are polyester fibers that contain a flame retardant.
10 . The fabric according to claim 8 , wherein the polyester fibers have an irregularly shaped cross-section.
11 . The fabric according to claim 8 , wherein the cross-sectional shape of monofilaments in the polyester fibers is flat, W-shaped, cross-shaped, hollow or triangular.
12 . The fabric according to claim 8 , wherein the aramid fibers and/or the electrically conductive fibers and/or the polyester fibers are contained in the fabric as spun yarn.
13 . The fabric according to claim 8 , wherein the aramid fibers and the polyester fibers are contained in the fabric as blended yarn.
14 . The fabric according to claim 1 , wherein the fabric has a double weave structure.
15 . The fabric according to claim 1 , wherein the hydrophilizing agent is polyethylene glycol diacrylate, a derivative of polyethylene glycol diacrylate, polyethylene terephthalate-polyethylene glycol copolymer, water-soluble polyurethane, or polyethylene glycol-aminosilicone copolymer.
16 . The fabric according to claim 1 , wherein the basis weight of the fabric is within the range of 130 g/m 2 to 260 g/m 2 .
17 . The fabric according to claim 1 , wherein the fabric is subjected to dyeing processing.
18 . The fabric according to claim 1 , wherein afterflame obtained by measuring flammability as defined in Method A-4 of JIS L1091-1992 is 2.0 seconds or less.
19 . The fabric according to claim 1 , wherein moisture absorption performance as defined in AATCC79 is 10 seconds or less.
20 . The fabric according to claim 1 , wherein water absorption performance as defined in AATCC79 after 20 cycles of laundering as defined in ISO6339-2012 (6N-F) is 30 seconds or less.
21 . A textile product that uses the fabric according to claim 1 and is selected from the group consisting of protective clothing, fire-protective clothing, fire-fighting clothing, rescue clothing, workwear, police uniforms, self defense forces uniforms and military clothing.Join the waitlist — get patent alerts
