Abstract
An arc resistant acrylic fiber includes an acrylic polymer. The arc resistant acrylic fiber also includes an infrared absorber in an amount of 1 wt % to 30 wt % with respect to a total weight of the acrylic polymer.
Claims14
An arc resistant acrylic fiber comprising:
- an acrylic polymer comprising acrylonitrile in an amount of 40 to 70 wt %, a halogen-containing vinyl-based monomer in an amount of 30 to 57 wt %, and a sulfonic group-containing monomer in an amount of 0 to 3 wt %, with respect to a total weight of the acrylic polymer, and
- an infrared absorber in an amount of 1 wt % to 30 wt % with respect to a total weight of the acrylic polymer,
- wherein the infrared absorber is a tin oxide based compound, and
- wherein the infrared absorber is dispersed throughout the interior of the fiber.

A fabric for arc-protective clothing, comprising:
- a cellulosic fiber,
- an infrared absorber, and
- a flame retardant,
- wherein an average total reflectivity of any of the front surface and the back surface of the fabric is 60% or less with respect to incident light with a wavelength of 750 to 2500 nm and the difference in the average total reflectivity with respect to incident light with a wavelength of 750 to 2500 nm between the front surface and the back surface is 5% or less, and
- the infrared absorber is a tin oxide based compound.
