Method of making a dual performance nonwoven and the products therefrom

Abstract

The present invention is directed to a cleaning laminate, which comprises an abrasive side that facilitates loosening of particulates, such as dust and dirt, and an opposing, soft absorbent side. The laminate is formed by hydroentanglement on a three-dimensional image transfer device.

What is claimed is:  
     
         1 . A method of making a dual performance nonwoven laminate comprising dual performance nonwoven laminate comprising an abrasive side and an opposing absorbent side comprising the steps of: 
 a. providing an absorbent precursor web;    b. providing a polymeric resin;    c. extruding said polymeric resin into filaments in the range of 5-50 microns;    d. collecting said filaments onto said absorbent precursor web to form a laminate;    e. advancing said laminate onto said three-dimensional image transfer device wherein said filaments are facing the hydraulic jets and said absorbent web is facing the three-dimensional image transfer device; and    hydroentangling said laminate so as to provide for a dual performance nonwoven laminate comprising an abrasive side and an opposing absorbent side.    
     
     
         2 . A method of making a dual performance nonwoven laminate comprising an abrasive side and an opposing absorbent side comprising the steps of: 
 a. providing an absorbent precursor web;    b. providing a three-dimensional image transfer device;    c. providing a meltblown precursor web comprising filaments in the range of 5-50 microns;    d. juxtaposing said absorbent precursor web with said precursor meltblown web;    e. advancing said precursor webs onto said three-dimensional transfer device wherein said meltblown web is facing the hydraulic jets and said absorbent web is facing said three-dimensional transfer device; and    hydroentangling said precursor webs so as to provide for a dual performance nonwoven laminate comprising an abrasive side and an opposing absorbent side.    
     
     
         3 . A method of making a dual performance nonwoven laminate comprising an abrasive side and an opposing absorbent side comprising the steps of: 
 a. providing an absorbent precursor web;    b. providing a three-dimensional image transfer device;    c. providing a meltblown precursor web comprising filaments in the range of 5-50 microns;    d. juxtaposing said absorbent precursor web with said precursor meltblown web;    e. advancing said precursor webs onto said three-dimensional transfer device wherein said absorbent web is facing the hydraulic jets and said meltblown web is facing said three-dimensional transfer device; and    hydroentangling said precursor webs so as to provide for a dual performance nonwoven laminate comprising an abrasive side and an opposing absorbent side.    
     
     
         4 . A dual performance nonwoven laminate formed in accordance with the method of  claim 1 .  
     
     
         5 . A dual performance wipe wherein said wipe is formed in accordance with the method of  claim 2 .  
     
     
         6 . A dual performance wipe wherein said wipe is formed in accordance with the method of  claim 3 , and comprises a cleaning agent.
