Embodiment 1

[0154] Embodiment 1 is a wipe that includes (a) a substrate, the substrate includes a sponge, a woven fabric, or a non-woven fabric, and (b) a cationic coating that is disposed on the On the surface of the substrate, it is distributed through at least a part of the substrate, or both. The cationic coating includes a guanidine group-containing polymer that is cross-linked, covalently bonded to the substrate, or both. When the wipe comes into contact with an area of ​​a microbial-contaminated surface in the presence of a liquid, at least 99% of the microorganisms present on the microbial-contaminated surface are removed from the area by the wipe, and when the wipe When the substance contacts the area of ​​the surface contaminated by the microorganisms in the presence of the liquid and then contacts the second surface, no more than 0.2% of the microorganisms are transferred from the wipe to the second surface.

Embodiment 2

[0155] Embodiment 2 is the wipe according to embodiment 1, wherein the guanidine group-containing polymer is (a) a guanylating agent and (b) a carbonyl group-containing polymer precursor or an amino group-containing polymer precursor The reaction product.

Embodiment 3

[0156] Embodiment 3 is the wipe according to any one of embodiments 1 or 2, wherein the guanidine group-containing polymer is represented by formula (I):

[0157]

[0158] Where R 1 Is hydrogen, C 1 -C 12 (Hetero)alkyl, C 5 -C 12 (Hetero)aryl, or residue of the polymer chain; R 2 Is a covalent bond, C 2 To C 12 (Hetero) alkylene, or C 5 -C 12 (Hetero)arylene; R 3 Is hydrogen, C 1 -C 12 (Hetero)alkyl, C 5 -C 12 (Hetero)aryl, or when n is 0, it is a residue of the polymer chain; each R 4 Independently hydrogen, C 1 -C 12 (Hetero)alkyl, C 5 -C 12 (Hetero)aryl; R 5 Is hydrogen, C 1 -C 12 (Hetero)alkyl, or C 5 -C 12 (Hetero)aryl, or --N(R 4 ) 2 ; N is 0 or 1; m is 1 or 2; and x is an integer equal to at least 1.

Abstract

A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.

Description

Technical field [0001] The present disclosure relates to wipes with a cationic coating comprising a guanidine group-containing polymer. Also disclosed are methods of using wipes and methods of preparing wipes. Background technique [0002] Microbial contamination can be a problem in many fields of activity. Harmful microbial populations can harm health, can cause problems in the production of drugs and food, and can cause waste due to the harmful effects of such biologically active microbial contamination on sensitive compositions and materials. Many surfaces can contain microbial residues in quantities high enough to contaminate sensitive products or processes. Elimination or removal of such microbial residues is the desired goal. [0003] In the medical industry, it is customary to clean and / or disinfect environmental surfaces, medical equipment and devices to improve hygiene and patient safety. Effective disinfection must be against a broad spectrum of microorganisms, includ...
