Title:
ANTIMICROBIAL TREATMENT OF SYNTHETIC NONWOVEN TEXTILES
Document Type and Number:
WIPO Patent Application WO/2011/130101
Kind Code:
A3
Abstract:
Highly active, leach-resistant, antimicrobial nonwoven textiles are prepared by treating at least one surface of the nonwoven material with an anionic polyelectrolyte, such as carboxymethyl cellulose, alginic acid, poly(acrylic acid) etc and at least one select quaternary ammonium antimicrobial agent. The textiles of the invention, and products produced from them, exhibit a highly effective quick kill rate, for example a log 4 CFU reduction within a 5 minute contact time, against microbes such as fungi and gram (-) and gram (+) bacteria.
