Benefits of technology
The present invention relates to a method and synthetic fiber for creating a halogen stable anti-microbial fiber. The method involves mixing a polymer, an anti-microbial agent, and a cationic pigment, and then extruding the mixture to form the anti-microbial synthetic fiber. The cationic pigment can attract halogens or have known anti-microbial properties. The synthetic fiber can be used to create various products such as fabrics or nonwoven fabrics. The technical effect of this invention is that it provides a way to create a halogen stable anti-microbial fiber with improved durability and effectiveness.
Problems solved by technology
Moreover, because fibers and fabrics produced with known methods lose their effectiveness during repeated launderings with chlorine bleach, the laundering process required in these industries causes issues with known anti-microbial fibers and fabrics.
But in many cases pigments have been shown to have destructive effects on anti-microbial performance.
These destructive effects are only increased due to bleach treatments that are commonly used on sanitary fabrics.
Although present fabrics and methods of making fabrics are functional, they are not sufficiently effective or otherwise satisfactory.

Embodiment Construction
[0016]Referring now to the drawings, where like or similar elements are designated with identical reference numerals throughout the several views, and referring in particular to FIG. 1, it illustrates a method for manufacturing colored fibers with improved anti-microbial performance. At Step 100 a mixture is created, the mixture including a polymer, an anti-microbial alloy powder, and a cationic pigment. As used herein, a polymer refers to a compound suitable for fiber and fabric generation including, but not limited to, a thermoplastic polymer, polyester, nylon, rayon, polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyethylene terephthalate glycol (PETG), co-PET, polylactic acid (PLA), and polytrimethylene terephthalate (PTT). In a preferred embodiment, the polymer may be polyester for durability, wrinkle resistance and color retention or nylon for its anti-drip, slow burn properties.
[0017]An anti-microbial agent may be any suitable anti-microbial, such a...

Abstract
A method for producing fibers with improved color and anti-microbial properties is described. One embodiment includes a method for generating a halogen stable anti-microbial synthetic fiber, the method comprising creating a mixture that includes a polymer, an anti-microbial agent, and a non-halogen pigment, and extruding the mixture to form an anti-microbial synthetic fiber.
Description
PRIORITY[0001]This application is a divisional of U.S. application Ser. No. 13 / 276,069, filed Oct. 18, 2011, which claims the benefit of U.S. Provisional Application No. 61 / 394,242, filed Oct. 18, 2010, both of which are incorporated herein by reference in their entirety for all purposes.FIELD OF THE INVENTION[0002]The present invention relates to fibers and fabrics designed for the effective destruction of pathogens such as bacteria, mold, mildew, fungus, spores and viruses.BACKGROUND OF THE INVENTION[0003]Anti-microbial additives containing copper, silver, gold, and zinc, either individually or combined, have been effective against pathogens such as bacteria, mold, mildew, virus, spores, and fungus. Accordingly, fibers and fabrics have been produced with anti-microbial alloys in various synthetic polymers such as polyester, polypropylene, nylon, rayon, and polylactic acid (PLA). There are many uses and applications for these types of anti-microbial fibers and fabrics, including th...
