Abstract
A flame resistant textile material comprises a textile substrate, a flame retardant finish applied to the textile substrate, and an infrared-absorbing finish applied to the textile substrate.
Claims20
A treated 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 fibers, at least a portion of the fibers being cellulosic fibers,
- (b) a first finish applied to at least the first surface of the textile substrate, the first finish comprising a phosphorous-containing compound, the phosphorous-containing compound comprising a plurality of pentavalent phosphine oxide groups having amide linking groups covalently bonded thereto, at least a portion of the pentavalent phosphine oxide groups having three amide linking groups covalently bonded thereto;
- and
- (c) a second finish applied to the second surface of the textile substrate, the second finish comprising an infrared-absorbing material and a binder;
- wherein the first surface of the textile substrate exhibits an average reflectance of about 40% or greater in the wavelengths from 800 nm to 1,200 nm, and the second surface of the textile substrate exhibits a reflectance of about 30% or less at 800 nm and about 50% or less at 1,200 nm.

A treated 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 fibers, at least a portion of the fibers being cellulosic fibers,
- (b) a first finish applied to at least the first surface of the textile substrate, the first finish comprising a phosphorous-containing compound polymerized within at least a portion of the cellulosic fibers, and the phosphorous-containing compound being a product produced by heat-curing and oxidizing a reaction mixture comprising:
- (i) a first chemical selected from the group consisting of tetrahydroxymethyl phosphonium salts, condensates of tetrahydroxymethyl phosphonium salts, and mixtures thereof;
- and
- (ii) a cross-linking agent selected from the group consisting of urea, guanidines, guanyl urea, glycoluril, ammonia, ammonia-formaldehyde adducts, ammonia-acetaldehyde adducts, ammonia-butyraldehyde adducts, ammonia-chloral adducts, glucosamine, polyamines, glycidyl ethers, isocyanates, blocked isocyanates, and mixtures thereof;
- and
- (c) a second finish applied to the second surface of the textile substrate, the second finish comprising an infrared-absorbing material and a binder;
- wherein the first surface of the textile substrate exhibits an average reflectance of about 40% or greater in the wavelengths from 800 nm to 1,200 nm, and the second surface of the textile substrate exhibits a reflectance of about 30% or less at 800 nm and about 50% or less at 1,200 nm.
