Abstract
An antimicrobially active, non-woven web, a wet wiper containing the web, and a method of making the web. The method includes the steps of forming an unbonded fibrous web; applying throughout the unbonded fibrous web an uncured binder and an antimicrobial agent, the antimicrobial active agent being substantive to the fibers of the web and to the binder; and curing the binder material to bind the fibers together to form an antimicrobially active, non-woven web. A preferred antimicrobial agent is an organo-silicon quaternary ammonium salt, especially a 3-(trimethoxylsilyl) propyldidecylmethyl ammonium chloride or a 3-(trimethoxysilyl) propyloctadecyldimethyl ammonium chloride.
Claims12
An antimicrobially active, non-woven web comprising:
- (a) bonded fibers;
- (b) a binder substantially uniformly distributed on the fibers, the binder being present in an amount effective to bind the fibers;
- and
- (c) an antimicrobial agent substantially uniformly distributed on the fibers, the antimicrobial agent being substantive to the fibers and to the binder when the web is either wet or dry to prevent the antimicrobial agent from substantially diffusing from the fibers or the binder.
