Hydrophilic nonwoven fabric

Abstract

The present invention is to provide a hydrophilic nonwoven fabric which can reveal hydrophilicity even after exposure to high temperature. The hydrophilic nonwoven fabric comprising an olefinic polymer containing a hydrophilic agent is characterized in that hydrophilicity can be revealed after heating treatment for an hour at 60° C. The nonwoven fabric is manufactured by using an olefinic polymer (B) and a master batch where a hydrophilic agent is included in an olefinic polymer (A), wherein an MFR (melt flow rate) of a master batch is preferably the same as or lower than the MFR of an olefinic polymer composition forming the nonwoven fabric.

1 . A nonwoven fabric comprising polyolefin in which liquid transport is recognized within 10 seconds as measured by the liquid transport speed specified in EDANA 150 2-93 after heating treatment for an hour at 60° C.  
   
   
       2 . The nonwoven fabric according to  claim 1 , wherein said polyolefin is an olefin polymer containing a hydrophilic compound.  
   
   
       3 . The nonwoven fabric according to  claim 1 , wherein said polyolefin is an olefin polymer where a hydrophilic compound is contained as one mixture compounded.  
   
   
       4 . The nonwoven fabric according to  claim 1 , wherein the nonwoven fabric is made from polyolefin formed by using a hydrophilic compound as a master batch where the melt flow index of the master batch is same or lower than the melt flow index of polyolefin.  
   
   
       5 . The nonwoven fabric according to  claim 1 , wherein the nonwoven fabric is a spunbonded nonwoven fabric or a meltblown nonwoven fabric.
