Abstract
An antimicrobially active wet wiper and a method of making the wiper. The wet wiper has an antimicrobially active non-woven web that includes: (i) bonded fibers; (ii) a binder in an amount effective to bind the fibers; and (iii) a first antimicrobial agent that is substantive to the fibers and to the binder when the web is either wet or dry. The web is maintained in a wet condition in a liquid containing a second antimicrobial agent until use.

An antimicrobially active wet wiper comprising:
- (a) an antimicrobially active non-woven web comprising:
- (i) bonded fibers;
- (ii) a binder in an amount effective to bind the fibers;
- (iii) a first antimicrobial agent being substantive to the fibers and to the binder when the web is either wet or dry;
- and
- (b) a liquid containing a second antimicrobial agent, the web being maintained in a wet condition in the liquid until use.
An antimicrobially active wet wiper comprising:
- (a) an antimicrobially active non-woven web comprising:
- (i) bonded cellulosic fibers;
- (ii) a polymeric binder in an amount effective to bind the fibers;
- (iii) a antimicrobial agent being substantive to the fibers and to the binder when the web is either wet or dry;
- and
- (b) a liquid containing an antimicrobial organic acid, the web being maintained in a wet condition in the liquid until use.
A method for preparing an antimicrobially active wet wiper comprising the steps of:
- (a) forming an unbonded fibrous web;
- (b) applying throughout the unbonded fibrous web an uncured binder and a first antimicrobial agent, the first antimicrobial agent being substantive to the fibers of the web and to the binder when the web is either wet or dry;
- (c) curing the binder to bind the fibers together to form an antimicrobially active, non-woven web;
- and
- (d) storing the web in a liquid containing a second antimicrobial agent to maintain the web in a wet condition until use.
