Reaktionsschritte

An equivalent of zinc carbonate was added to acrylic acid in dilute solution to obtain a solution of zinc acrylate. From this solution and other ingredients, there was prepared an aqueous solution containing 1% acrylic acid, 0.9% zinc carbonate, 0.25% MBA, 8% DMDHEU, 2% polyethylene softener, 0.1% wetting agent, and 0.5% K2S2O8. Cotton printcloth was impregnated in this reagent solution to a wet pickup of approximately 105%. The wet fabric was placed on pin frames in heat-resistant plastic bags that were flushed with nitrogen. The samples of fabrics in the bags were subjected to heating in forced-draft ovens at 120° C for 10 minutes, immediately followed by 160° C for 5 minutes. The samples of fabric were washed extensively in hot running tap water and line dried. The weight gain due to add-on of reagent was 7.1%; the nitrogen incorporated into the fabric was 0.88% and the zinc incorporated was 0.39%. The DP appearance rating was 3.1. Textile properties are summarized in Table I and antibacterial properties are summarized in Table III.
