Abstract: A process for effectively dyeing 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 a dyeing auxiliary agent that provides a charged surface to the composite item, contacting the charged surface with a composition comprising a dye that interacts with the charged surface, reacts with the charged surface, or both, and drying the dyed composite item, and the dyed composite items obtained therefrom, as well as the use of the dyeing auxiliary agent on heretofore difficult to dye fibers, yarns, fabrics or articles such as mineral or metal fibers and products obtained therefrom.

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.
