Abstract
Methods and treatment compositions for imparting durable antimicrobial properties to carpet are provided. The method includes applying a composition comprising a first antimicrobial compound and a fluoropolymer to the carpet substrate. The carpet substrate may be steamed thereafter. The treatment composition may comprise a fluoropolymer, an antimicrobial compound selected from a group consisting of zinc pyrithione, a silver-containing antimicrobial compound and combinations thereof, and a foamer. Carpet products treated with the treatment composition or treated in accordance with the methods are also provided.
Claims16
A method of treating a carpet substrate comprising:
- preparing a composition comprising zinc pyrithione, a silver-containing antimicrobial compound, a magnesium sulfate liquid, and a fluoropolymer;
- adjusting the pH of the composition to a pH of about 2.0 to about 12.0;
- applying the composition to the carpet substrate in the form of a foam;
- steaming the carpet substrate immediately after application of the composition to the carpet substrate;
- rinsing and extracting the carpet substrate;
- and
- drying the carpet substrate in a dryer.
A method of treating a carpet substrate comprising:
- preparing a composition comprising a fluoropolymer, a magnesium sulfate liquid, zinc pyrithione, a zirconium phosphate-based ceramic ion-exchange resin containing silver, and a pH adjusting additive;
- applying the composition to the carpet substrate in the form of a foam;
- and thereafter
