Abstract
Compositions and methods are described that provide cellulosic and non-cellulosic fabrics with durable antimicrobial properties. Application of a coating that includes polyhexamethylene biguanide, polyethylene glycol, and a binder to a fabric followed by drying and curing was found to provide antimicrobial properties that are retained through over 100 washings under aggressive hospital washing conditions. In addition, tactile properties and tear resistance of the treated fabrics are maintained or improved.
Claims9
A wash-durable antimicrobial textile, comprising:
- a textile substrate;
- and
- an antimicrobial composition comprising 5% to 15% v/v polyhexamethylene biguanide, 5% to 10% v/v polyethylene glycol having a molecular weight of 300 Daltons to 1,000 Daltons, and 3% to 8% v/v of a binder,
- wherein at least a portion of the antimicrobial composition is chemically bonded to the to the textile substrate, and wherein the wash-durable antimicrobial textile exhibits antibacterial, antiviral, and antifungal properties.
The wash-durable antimicrobial textile, wherein at least one of tearing strength, resilience, softness, and smoothness of the wash-durable antimicrobial textile is increased relative to the textile substrate alone.
An article of clothing having anti-microbial properties, comprising:
- a textile comprising a cellulosic or synthetic polymer fiber coated with an antimicrobial composition, wherein the antimicrobial composition comprises comprising 5% to 15% v/v polyhexamethylene biguanide, 5% to 10% v/v polyethylene glycol having a molecular weight of 300 Daltons to 1.000 Daltons, and 3% to 8% v/v of a binder,
- wherein at least a portion of the antimicrobial composition is chemically bonded to the to the textile, and wherein the article of clothing exhibits antibacterial, antiviral, and antifungal properties.
