Wiper and method for manufacturing the same

Abstract

Disclosed is a wiper which is which is highly retentive of water, soft to the touch, and improved in sheet strength and a method for manufacturing the same. An interlining layer contains pulp fibers, first and second surfacing layers contain non-fusible fibers, and a reinforcing layer contains fusible fibers and rayon fibers. The fusible fibers are fusion-bonded but the non-fusible fibers remain unfused. Sheet surfaces are free from the fusible fibers.

         6 . A method for manufacturing a wiper comprising:
 forming a multilayered fibrous web with a reinforcing layer-forming fibrous web and an interlining layer-forming fibrous web located between a first surfacing layer-forming fibrous web and a second surfacing layer-forming fibrous web, the reinforcing layer-forming fibrous web comprising fusible fibers, the interlining layer-forming fibrous web comprising hydrophilic fibers, the first surfacing layer-forming fibrous web and the second surfacing layer-forming fibrous web comprising non-fusible fibers whose surface has a higher melting point than that of the fusible fibers or is not allowed to melt,   integrating the multilayered fibrous web through a water-jet treatment; and   heat-treating the integrated multilayered fibrous web at such a temperature as to melt the surface of the fusible fibers but not melt the surface of the non-fusible fibers.   
     
     
         7 . A method according to  claim 6 , wherein cellulosic fibers having a fiber length equal to or less than 10 mm are deposited to form the interlining layer-forming fibrous web. 
     
     
         8 . A method according to  claim 6 , wherein at least either of synthetic resin fibers or cellulosic fibers having a fiber length in the range of 20 to 70 mm are deposited to form the first surfacing layer-forming fibrous web. 
     
     
         9 . A method according to  claim 6 , wherein at least either of synthetic resin fibers or cellulosic fibers having a fiber length in the range of 20 to 70 mm are deposited to form the second surfacing layer-forming fibrous web. 
     
     
         10 . A method according to  claim 6 , wherein the reinforcing layer-forming fibrous web contains non-fusible fibers in addition to the fusible fibers.
