  • Antimicrobial cut-resistant composite yarn and garments knitted or woven therefrom
    Patent number: 7121077
    Abstract: An antimicrobial, cut-resistant composite yarn has a core including at least one cut-resistant strand, and a cover including at least one strand wrapped around and enclosing the core. At least one strand in either the core or the cover is treated with and incorporates an antimicrobial compound. In addition, the yarn can include one or more channel fibers to facilitate movement of moisture within the composite yarn so that the moisture contacts the antimicrobial compound, thereby enhancing the efficacy of the antimicrobial compound. The yarn can be used to fabricate cut-resistant garments, such as gloves, worn by meat cutters and others who work with knives, saws and other sharp implements. The antimicrobial effect reduces bacteria, mold and fungi growth on the garments between washings.
