Abrasive scrubber

Abstract

Articles and methods regarding abrasive articles that include antimicrobial properties and improved abrasive performance and comprise a first fiber element comprising a woven or non-woven material; and a second fiber element comprising metal, wherein the second fiber element comprises at least one self-interlocking arrangement.

What is claimed is: 
     
         1 . A scrubbing article comprising:
 a first layer comprising:   a first fiber element comprising a woven or non-woven material; and   a second fiber element comprising metal, wherein the second fiber element comprises at least one self-interlocking arrangement; and   a binder overlying at least a portion of the first layer, wherein the binder comprises an antimicrobial agent.   
     
     
         2 . The abrasive article of  claim 1 , wherein the antimicrobial agent comprises ZPT. 
     
     
         3 . The abrasive article of  claim 1 , wherein the abrasive article comprises a bacterial reduction against  Staphylococcus aureus  of at least 95% according to ASTM 2149-13a of at least 96% or at least 97% or at least 98% or at least 99% or at least 99.5%. 
     
     
         4 . The abrasive article of  claim 1 , wherein the abrasive article comprises a bacterial reduction against  Escherichia coli  of at least 95% according to ASTM 2149-13a of at least 96% or at least 97% or at least 98% or at least 99% or at least 99.5%. 
     
     
         5 . The abrasive article of  claim 1 , wherein the abrasive article comprises a bacterial reduction against  Klebsiella pneumonia  of at least 95% according to ASTM 2149-13a of at least 96% or at least 97% or at least 98% or at least 99% or at least 99.5%. 
     
     
         6 . The abrasive article of  claim 1 , wherein the stiffness of the abrasive article is at least 1800 mg. 
     
     
         7 . The abrasive article of  claim 1 , wherein the binder comprises a first glass transition temperature Tg1 and a second glass transition temperature Tg2, wherein Tg2>Tg1. 
     
     
         8 . The abrasive article of  claim 7 , wherein Tg1 is at least 200 K and not greater than 300K. 
     
     
         9 . The abrasive article of  claim 7 , wherein Tg1 is at least 250 K and not greater than 350K. 
     
     
         10 . The abrasive article of  claim 7 , wherein Tg1/Tg2 is at least 1.01 and not greater than 1.5. 
     
     
         11 . The abrasive article of  claim 7 , wherein Tg1-Tg2 is at least 1 K and not greater than 100 K. 
     
     
         12 . The abrasive article of  claim 1 , wherein the binder comprises a self-crosslinkable resin and a non-self-crosslinkable resin. 
     
     
         13 . The abrasive article of  claim 1 , wherein the concentration of antimicrobial agent in the binder is at least 2 wt %. 
     
     
         14 . The abrasive article of  claim 1 , further comprising a substrate layer. 
     
     
         15 . A scrubbing article comprising:
 a first layer comprising:
 a first fiber element comprising a woven or non-woven material; and 
   
       a second fiber element comprising a metal ribbon, the second fiber element extending along a tortuous pathway within the first layer, and a binder overlying at least a portion of the first layer, wherein the first layer comprises a stiffness of at least 1800 mg and not greater than 4000 mg. 
     
     
         16 . The abrasive article of  claim 1 , wherein the binder comprises a first glass transition temperature Tg1 and a second glass transition temperature Tg2, wherein Tg2>Tg1. 
     
     
         17 . The abrasive article of  claim 15 , wherein Tg1 is at least 200 K and not greater than 300K. 
     
     
         18 . The abrasive article of  claim 15 , wherein Tg1 is at least 250 K and not greater than 350K. 
     
     
         19 . The abrasive article of  claim 15 , wherein Tg1/Tg2 is at least 1.01 and not greater than 1.5. 
     
     
         20 . The abrasive article of  claim 15 , wherein the binder comprises a self-crosslinkable resin and a non-self-crosslinkable resin.
