Embodiment 1

[0071] Embodiment 1. A fabric formed from a first yarn and a second yarn, wherein the fabric has a first side and a second side opposite the first side, and wherein: the first yarn comprises a second side A fiber blend, the first fiber blend comprising aramid fiber, modacrylic fiber and cellulose fiber; the aramid fiber and modacrylic fiber of the first fiber blend acrylonitrile fibers comprise at least 50% of said first fiber blend; said first fiber blend comprises more modacrylic fibers than aramid fibers; said second yarn comprises Two fiber blends, the second fiber blend being different from the first fiber blend and comprising aramid fibers, modacrylic fibers, and cellulose fibers; the second fiber blend The fabric comprises at least 60% cellulose fibers; the second fiber blend comprises more modacrylic fibers than aramid fibers; the first yarns are primarily exposed on the first side of the fabric above; the second yarn is primarily exposed on the second side of the fab...

Embodiment 2

[0072] Embodiment 2. The fabric of any preceding or subsequent embodiment or combination of embodiments, wherein the aramid fibers and modacrylic fibers of the first fiber blend comprise the first fibers At least 60% of the blend.

Embodiment 3

[0073] Embodiment 3. The fabric of any preceding or following embodiment or combination of embodiments, wherein the first fiber blend comprises modacrylic fibers up to twice as many polyaramid fibers.

Abstract

Embodiments of the present invention relate to flame resistant fabrics formed with inherently flame resistant fibres that provide the requisite thermal and arc protection, that have improved comfort, and that, in some embodiments, are less expensive than other fabrics formed with inherently flame resistant fibres. Improved comfort and lower cost can be achieved by predominantly locating the inherently flame resistant fibres such as modacrylic and a ram id on the front face of the fabric to impart the requisite thermal and arc protection and predominantly locating the more comfortable (and less expensive) fibres such as cellulose on the back face of the fabric positioned next to the wearer. In this way, overall protection of the fabric is maintained while improving comfort. Some embodiments of such fabrics may also achieve NFPA 70E PPE Category 2 protection.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 825,350, entitled "Low Cost Flame Resistant Fabrics with Inherently Flame Resistant Fibers," filed March 28, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments of the present invention relate to low cost and low weight flame resistant protective fabrics and garments made therefrom that impart improved protection to the wearer. Background technique [0004] Many occupations can potentially expose individuals to arc flashes and / or flames. Workers who may be exposed to accidental arc flashes and / or flames risk severe burns unless they are properly protected. To avoid injury while working in such conditions, these individuals typically wear protective clothing constructed of flame retardant materials designed to protect them from arc flashes and / or flames. Such protective clothing may incl...
