Nonwoven fabric for cleaning and a production method for the same

Abstract

The present invention relates to a nonwoven fabric for cleaning and to a production method for the same. Provided is a nonwoven fabric for cleaning and a production method therefor, comprising: a raw-material supply step in which between 80 and 90 parts by weight of cotton fibre and between 10 and 20 parts by weight of synthetic fibre are introduced; a step in which the introduced raw materials are mixed by using a blowing and scutching machine; a step in which a web is produced in the form of a sheet by using a carding machine to process the mixed raw materials; a step in which a fibrous web is produced by layering a plurality of the webs and then spraying a water jet so as to join the plurality of webs to each other; and a heat-treatment step in which the fibrous web is subjected to hot drying, and the synthetic fibre is softened and the bond with the cotton fibre is strengthened. Also provided is a production method for the nonwoven fabric. According to the present invention, a nonwoven fabric for cleaning can be provided which maintains the water absorbency and the oil absorbency while markedly increasing the tensile strength of the cotton fibre.

1 . A nonwoven fabric production method for cleaning, comprising:
 a raw material supply step for inputting 80-90 weight % of a cotton plug and 10-20 weight % of a synthetic fiber;   a step for mixing the inputted raw materials using a scutching machine;   a step for producing a sheet-shaped web by processing the mixed raw materials using a carding machine;   a step for producing a fiber web in such a way to stack a plurality of the webs and to spray a water jet and to bind a plurality of the webs; and   a step for heat-drying the fiber webs and smoothing the synthetic fibers and enhancing a binding with the cotton plug.   
     
     
         2 . The method of  claim 1 , wherein the synthetic fiber is a poly olefin-based fiber or a polyester fiber having a melting point of 100-120° C. 
     
     
         3 . The method of  claim 1 , wherein the raw material supply step has features in that the cotton fiber and the synthetic fiber are alternately stacked and form at least three stages and then are supplied. 
     
     
         4 . The method of  claim 1 , wherein the heat treatment step has features in that the fiber web is processed for 80-100° C. for 50-120 seconds by a heat-wind device and/or a heating roll. 
     
     
         5 . A nonwoven fabric for cleaning which is manufactured by a production method defined in  claim 1 . 
     
     
         6 . A nonwoven fabric for cleaning which is manufactured by a production method defined in  claim 4 . 
     
     
         7 . The method of  claim 2 , wherein the heat treatment step has features in that the fiber web is processed for 80-100° C. for 50-120 seconds by a heat-wind device and/or a heating roll. 
     
     
         8 . The method of  claim 3 , wherein the heat treatment step has features in that the fiber web is processed for 80-100° C. for 50-120 seconds by a heat-wind device and/or a heating roll. 
     
     
         9 . A nonwoven fabric for cleaning which is manufactured by a production method defined in  claim 2 . 
     
     
         10 . A nonwoven fabric for cleaning which is manufactured by a production method defined in  claim 3 .
