The instant disclosure relates to textile materials having an acid reactive functionalized polymer layer and a non-acid reactive functionalized layer coupled thereto. The acid reactive functionalized polymer layer may include: a polyamide polymer that captures and neutralizes acidic molecules; a hydrophilic polyether block amide copolymer; a maleic anhydride-grafted ethylene copolymer; and a non-halogenated flame retardant. The acid reactive functionalized polymer layer is fire resistant, acid neutralizing, and allows water vapor to transfer therethrough. The non-acid reactive functionalized layer and acid reactive functionalized polymer layer are free of per- and polyfluoroalkyl substances. The polyamide may include Nylon 12, Nylon 6, or Nylon 6,6 functionalized with an amine (e.g., a pyridine derivative and/or a halogenated-dimethylalkylamine) having a nitrogen that captures and neutralizes acidic molecules. The halogenated-dimethylalkylamine may include a general chemical formula of (CH3)2N—R—X, where R is an alkyl containing 1-12 carbon atoms, and X is chlorine or bromine.
