Abstract: A process for providing antimicrobial properties to a composite item, such as a composite yarn, composite fabric or composite article, is provided involving the steps of immersing the composite item in a aqueous bath containing an organic antimicrobial agent, separating the immersed composite item from the bath and drying the separated composite item, and the antimicrobial composite items provided therefrom.

Abstract: A process for dyeing spandex. The process includes the steps of setting the dyebath with an organic acid; adding a pre-metallized acid dye to the dyebath; heating the dyebath until completion of dyeing; and cooling the dyebath. In the preferred embodiment the organic acid is selected from the group including formic and acetic acid. Also, in the preferred embodiment, the dyebath is heated at a rate of between about 0.5 F. and 3 F. per minute up to a temperature of between about 220 F. and 250 F. The resulting dyed spandex passes an AATCC IIA wash test.
