Nonwoven fabric and method for making same

Abstract

A nonwoven fabric suitable to be used as a kitchen paper including thermoplastic synthetic fibers being 7˜30 mm long and as fine as of 0.1˜0.8 d, in 90˜10% by weight and pulp fibers being 2˜7 mm long, in 10˜90% by weight, these component fibers being mixed together as homogeneously as possible and mechanically entangled so as to have a basis weight of 10˜80 g/m 2 as a whole.

What is claimed is:  
     
         1 . A nonwoven fabric containing thermoplastic synthetic microfibers, said nonwoven fabric comprising: 
 thermoplastic synthetic fibers being 5˜30 mm long and as fine as of 0.1˜0.8 d, in 90˜10% by weight, mixed and mechanically entangled with pulp fibers being 2˜7 mm long, in 10˜90% by weight, so as to have a basis weight of 10˜80 g/m 2  as a whole.    
     
     
         2 . A nonwoven fabric according to  claim 1 , wherein said thermoplastic synthetic fibers preferably is melt blown fibers.  
     
     
         3 . A nonwoven fabric according to  claim 1 , wherein said nonwoven fabric is a kitchen paper or wipe-out sheet.  
     
     
         4 . A method for making nonwoven fabric containing thermoplastic synthetic microfibers, said method comprising the steps of: 
 a. obtaining a wet sheet from slurry containing 0.5˜20% by weight of a fibrous mixture dispersed in water, said fibrous mixture comprising, in 90˜10% by weight, thermoplastic synthetic fibers being 7˜30 mm long and as fine as of 0.1˜0.8 d mixed with pulp fibers being 2˜7 mm long, in 10˜90% by weight; and    b. placing said wet sheet on a support and then subjecting said wet sheet to high velocity water jet streams of 50˜200 kgf/cm 2  for mechanically entangling said fibrous mixture.    
     
     
         5 . A method according to  claim 4 , wherein said thermoplastic synthetic fibers preferably is melt blown fibers.
