Abstract
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.
