Disposable Cleaning Cloths and Associated Methods

Abstract

A disposable cleaning cloth includes a low weight substrate having a first face and an opposed second face. The disposable cleaning cloth further includes microfiber yarn sewn to the low weight substrate in a plurality of parallel rows of straight stiches. The straight stitches are substantially flush with the first and second faces of the substrate. A method of making a disposable cleaning cloth includes providing a low weight substrate having a first face and an opposed second face. The method further includes sewing a microfiber yarn to the low weight substrate in a plurality of parallel rows of straight stiches, such that the straight stitches are substantially flush with the first and second faces of the substrate.

What is claimed is: 
     
         1 . A disposable cleaning cloth, comprising:
 a low weight substrate having a first face and an opposed second face; and   microfiber yarn sewn to the low weight substrate in a plurality of parallel rows of straight stiches, such that the straight stitches are substantially flush with the first and second faces of the substrate.   
     
     
         2 . The disposable cleaning cloth of  claim 1 , wherein the low weight substrate has a weight of 70 g/m 2  or less. 
     
     
         3 . The disposable cleaning cloth of  claim 1 , wherein the low weight substrate comprises a nonwoven fabric. 
     
     
         4 . The disposable cleaning cloth of  claim 3 , wherein the nonwoven fabric comprises nonwoven polyester, polypropylene, nylon, acrylic, cotton, rayon, or blend of any of these materials. 
     
     
         5 . The disposable cleaning cloth of  claim 1 , wherein the microfiber yarn comprises microfibers of polyester, polypropylene, nylon, or a blend of any of these materials. 
     
     
         6 . The disposable cleaning cloth of  claim 5 , wherein the microfibers each have a denier of from about 0.36 to about 1. 
     
     
         7 . The disposable claim cloth of  claim 1 , wherein the microfiber yarn has a denier of from about 100 to about 200. 
     
     
         8 . The disposable cleaning cloth of  claim 1 , wherein the microfiber yarn is formed of from about 250 to about 350 microfiber filaments. 
     
     
         9 . The disposable cleaning cloth of  claim 1 , wherein the straight stitches of the microfiber yarn are present in about 150 to about 250 stiches per square inch. 
     
     
         10 . The disposable cleaning cloth of  claim 1 , further comprising a fiber yarn sewn to the low weight substrate in a plurality of parallel rows of straight stiches, such that the straight stitches are substantially flush with the first and second faces of the substrate, the fiber yarn stiches being substantially parallel to the microfiber yarn stiches. 
     
     
         11 . A method of making a disposable cleaning cloth, comprising:
 providing a low weight substrate having a first face and an opposed second face; and   sewing a microfiber yarn to the low weight substrate in a plurality of parallel rows of straight stiches, such that the straight stitches are substantially flush with the first and second faces of the substrate.   
     
     
         12 . The method of  claim 11 , wherein the low weight substrate has a weight of 70 g/m 2  or less. 
     
     
         13 . The method of  claim 11 , wherein the low weight substrate comprises a nonwoven fabric. 
     
     
         14 . The method of  claim 13 , wherein the nonwoven fabric is a nonwoven polyester, polypropylene, nylon, acrylic, cotton, rayon, or blend of any of these materials. 
     
     
         15 . The method of  claim 11 , wherein the microfiber yarn comprises microfibers of polyester, polypropylene, nylon, or a blend of any of these materials. 
     
     
         16 . The method of  claim 15 , wherein the microfibers each have a denier of from about 0.36 to about 1. 
     
     
         17 . The method of  claim 11 , wherein the microfiber yarn has a denier of from about 100 to about 200. 
     
     
         18 . The method of  claim 11 , wherein the microfiber yarn is formed of from about 250 to about 350 microfiber filaments. 
     
     
         19 . The method of  claim 11 , wherein the straight stitches of the microfiber yarn are sewn in about 150 to about 250 stiches per square inch. 
     
     
         20 . The method of  claim 11 , further comprising sewing a fiber yarn to the low weight substrate in a plurality of parallel rows of straight stiches, such that the straight stitches are substantially flush with the first and second faces of the substrate, the fiber yarn stiches being substantially parallel to the microfiber yarn stiches.
