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.

1 . A method of making a dual performance nonwoven laminate having an abrasive side and an opposing absorbent side comprising steps of: 
 a. providing an absorbent precursor web;    b. providing a polymeric resin that is usable in a spunbond process;    c. providing a three-dimensional image transfer device;    d. extruding said polymeric resin into meltblown filaments;    e. collecting said filaments onto said absorbent precursor web to form a laminate;    f. advancing said laminate onto said three-dimensional image transfer device wherein said filaments are facing 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 having an abrasive side and an opposing absorbent side comprising steps of: 
 a. providing an absorbent precursor web;    b. providing a three-dimensional image transfer device;    c. providing a meltblown precursor web solely made from resin usable in a spunbond process;    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 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 having an abrasive side and an opposing absorbent side comprising steps of: 
 a. providing an absorbent precursor web;    b. providing a three-dimensional image transfer device;    c. providing a meltblown precursor web solely made from resin usable in a spunbond process;    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 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.
