Abstract
Antitoxic fibers and fibrous media contain impregnated material including an antitoxin. A method for producing antitoxic fibers and fibrous media includes impregnating a fibrous media by dipping in a dipping solution containing a concentrate of an antitoxin to form a fiber with impregnated material including an antitoxin. The impregnated material is at least about 1.0% to about 2.5% by weight of the fibers and includes additive chemical components including at least one of an anionic, cationic or nonionic component, an oil and/or an organic solvent, and an alcohol. The additives include those found in a spin finish. The antitoxin is in an amount of at least 0.1% by weight of the fiber. The manufacturing process can be applied to any woven or nonwoven media. Products with antitoxic properties formed therefrom include wound dressings, gowns, articles of clothing, surgical drapes, protective clothing, shoe covers, gloves, hair covers, air filters, including facemasks, privacy, hygienic products, curtains, medical tape, and wipes.
