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.
An antitoxic fiber, the antitoxic fiber comprising a fiber formed of a polymeric or nonpolymeric material, and impregnated material impregnated into the fiber, the antitoxic fiber being characterized by a humidity measure of less than about 10%, wherein the impregnated material is at least 1.0% by weight of the antitoxic fiber based on dried fiber weight and includes at least one active antitoxin, wherein one of the at least one active antitoxin is triiodide, and additional chemical components, and
An antitoxic fabric formed of antitoxic fibers comprising fibers formed of a polymeric or nonpolymeric material and impregnated material impregnated into the fibers, wherein the impregnated material is at least 1.0% by weight of the antitoxic fibers based on dried fiber weight and includes at least one active antitoxin, wherein one of the at least one active antitoxin is triiodide, and additional chemical components, and wherein the additional chemical components include coconut fatty acids ethoxylated with ethylene oxide, phosphate ester formed from an ethoxylated fatty alcohol, and triethanolamine in sufficient proportion to stabilize the at least one active antitoxin, including the triiodide, in the antitoxic fibers and fabric, the antitoxic fabric being efficacious on contact and maintaining efficacy with negligible toxicity in use, and wherein a humidity measure of the antitoxic fabric is smaller than about 10%.
