Abstract
A disposable anti-microbial paper towel and dispensing method includes disposing paper towel in an automatic touchless dispenser which is adapted to generate a touchless proximity signal upon nearness of a consumer, and dispensing the paper towel in response to the proximity signal. A typical invention towel has: (i) a cellulosic web characterized in that the web is substantially without crepe bars and has an unlotioned MD bending length of at least 3.5 cm; and (ii) a transferable lotion composition comprising an emollient and anti-microbial agent, the lotion composition being immobilized on the cellulosic web in a semi-solid or solid form. The transferable lotion composition is selected from lotion compositions which are transferable upon contact with water or lotion compositions which are transferable upon application of body heat.

63. A method of making a fabric-creped absorbent anti-microbial paper towel with improved dispensing characteristics comprising:
-
a) compactively dewatering a papermaking furnish to form a nascent web;
b) applying the dewatered web to a translating transfer surface moving at a first speed;
c) fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping fabric, the creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the transfer surface and transferred to the creping fabric;
d) adhering the web to a drying cylinder with a resinous adhesive coating composition;
e) drying the web on the drying cylinder; and
f) peeling the web from the drying cylinder;
wherein the furnish, creping fabric and creping adhesive are selected and the velocity delta, nip parameters and web consistency, caliper and basis weight are controlled such that the MD bending length of the dried web is at least about 3.5 cm, and g) applying a transferable lotion composition to the web, the lotioned composition comprising an emollient and anti-microbial agent, the lotion composition being immobilized on the cellulosic web in a semi-solid or solid form, wherein the transferable lotion composition is selected from lotion compositions which are transferable upon contact with water or lotion compositions which are transferable upon application of body heat. - View Dependent Claims (64)
