Abstract
A textile material exhibiting enhanced energy absorption (e.g., enhanced near-infrared energy absorption) and, optionally, flame resistance. The textile material comprises a textile substrate and a finish disposed on at least one surface of the textile substrate. The finish comprises a binder and an energy-absorbing agent. A method for protecting an individual from infrared radiation that can be generated during an arc flash comprises the step of positioning a textile material between an individual and an apparatus capable of producing an arc flash.
Claims25
A textile material comprising:
- (a) a textile substrate having a first surface and a second surface opposite the first surface, the textile substrate comprising a plurality of yarns, the plurality of yarns comprising a plurality of first yarns disposed in a first direction in the textile substrate and a plurality of second yarns disposed in a second direction perpendicular to the first direction, the first yarns and the second yarns being provided in a woven pattern selected from the group consisting of basket weaves, sateen weaves, satin weaves, rip-stop weaves, and twill weaves, the textile substrate comprising about 30% or more by weight inherent flame resistant fibers;
- and
- (b) a finish disposed on at least one surface of the textile substrate, the finish comprising a binder and at least one energy-absorbing agent, the energy-absorbing agent being selected from the group consisting of pigments, vat dyes, and combinations thereof, wherein the energy-absorbing agent exhibits an absorbance of electromagnetic radiation at a wavelength of 1,000 nm (A1000), an absorbance of electromagnetic radiation at a wavelength of 800 nm (A800), an absorbance of electromagnetic radiation within the range of wavelengths from 400 nm to 700 nm, and a maximum of the absorbance of electromagnetic radiation within the range of wavelengths from 400 nm to 700 nm (Avis max), wherein the result of A800/Avis max is about 0.3 or more, and wherein the result of A1000/Avis max is about 0.1 or more.
A method for protecting an individual from infrared radiation that can be generated during an arc flash, the method comprising the step of positioning a textile material between an individual and an apparatus capable of producing an arc flash, the textile material comprising:
- (a) a textile substrate having a first surface and a second surface opposite the first surface, the textile substrate comprising a plurality of yarns, the plurality of yarns comprising a plurality of first yarns disposed in a first direction in the textile substrate and a plurality of second yarns disposed in a second direction perpendicular to the first direction, the first yarns and the second yarns being provided in a woven pattern selected from the group consisting of basket weaves, sateen weaves, satin weaves, rip-stop weaves, and twill weaves, the textile substrate comprising about 30% or more by weight inherent flame resistant fibers, and
- (b) a finish disposed on at least one surface of the textile substrate, the finish comprising a binder and at least one energy-absorbing agent, the energy-absorbing agent being selected from the group consisting of pigments, vat dyes, and combinations thereof, wherein the energy-absorbing agent exhibits an absorbance of electromagnetic radiation at a wavelength of 1,000 nm (A1000), an absorbance of electromagnetic radiation at a wavelength of 800 nm (A800), an absorbance of electromagnetic radiation within the range of wavelengths from 400 nm to 700 nm, and a maximum of the absorbance of electromagnetic radiation within the range of wavelengths from 400 nm to 700 nm (Avis max), wherein the result of A800/Avis max is about 0.3 or more, and wherein the result of A1000/Avis max is about 0.1 or more.
