Imaged nonwoven fabrics in dusting applications

Abstract

The present invention is directed a nonwoven fabric which is imparted with a three-dimensional image or pattern during the fabrication stage. The three-dimensional image or pattern imparted into the structure of the nonwoven fabric results in a lofty material with particulate capturing recesses or “pockets” which act to entrap and entrain dust. The three-dimensional image or pattern also results in a number of fibrous ends and loops which extend beyond the surface of the recesses or “pockets”, which in turn, improve the nonwoven fabrics ability to effectively collect particulates from the surface of the article to be cleaned or dusted. In conjunction, the recesses and the extended fibrous surface act to effectively remove fine particulates such as dust from articles such as furniture and flooring.

         5 . A method for dusting, comprising the steps of: 
 providing a nonwoven fabric comprising a prebond fibrous matrix of staple length fibers, said fabric being formed by hydroentangling the prebond fibrous matrix on a three-dimensional transfer device so as to impart a three-dimensional pattern into the resultant nonwoven fabric,    said fabric exhibiting an array of pockets having the ability to entrap and entrain particulate matter from a soiled surface, and a basis weight on the order of 55 to 75 grams per square meter; and    employing said nonwoven fabric for removing particulate matter from said soiled surface.    
     
     
         6 . A method in accordance with  claim 5 , wherein: 
 said array of pockets has a grid pattern.    
     
     
         7 . A method in accordance with  claim 5 , wherein: 
 said fibrous matrix comprises a polyester and rayon blend.
