Abstract

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.

Abstract

A modified acid neutralizing polymer material includes a substrate having a surface including an acid neutralizing polymer material and a modified layer formed on the acid neutralizing polymer material surface. The modified layer includes a reaction product between a basic salt solution and the acid neutralizing polymer material surface. A method for preparing the modified acid neutralizing polymer material includes receiving a substrate comprising an acid neutralizing polymer material, applying a basic salt solution to the substrate to create a modified substrate through a reaction product between the basic salt solution and the acid neutralizing polymer material to form the modified acid neutralizing polymer material, allowing the basic salt solution to evaporate from the modified substrate, and optionally, removing unreacted basic salt material from the modified acid neutralizing polymer material.

Abstract

A method of making an acid neutralizing polymer material includes preparing a first reaction mixture including a buffering agent and an amine salt of either a halogenated tertiary amine or a haloalkyl heterocyclic aromatic amine. The first reaction mixture is added to a first compounding machine and reacted for a time and at a temperature sufficient to produce a neutralized amine. A second reaction mixture including a polyamide material and a strong base is prepared, added to the first reaction product and reacted for a time and at a temperature sufficient to produce the acid neutralizing polymer material. Alternatively, the buffering agent, amine salt of either a halogenated tertiary amine or a haloalkyl heterocyclic aromatic amine, and the polyamide material may be added and reacted for a time and at a temperature sufficient to produce the acid neutralizing polymer material.
