摘要： 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.

摘要： A method of preparing an acid reactive functionalized polyamide includes preparing a first reaction product by contacting and reacting virgin polyamide fabric material with tert-butoxide in a first aliquot of a polar aprotic solvent and preparing a second reaction product by adding an amine to a second aliquot of the polar aprotic solvent. A third reaction product is prepared by mixing the first reaction product and the second reaction product where the third reaction product is the acid reactive functionalized polyamide. The preparation of each respective reaction product is for a period of time and at a temperature sufficient to produce the respective reaction product.

摘要： 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.
