Cleaning Cloth

Abstract

The present invention provides a cleaning cloth, in which a large number of parallel ridge regions are formed at predetermined intervals in a nonwoven cloth made of synthetic resin fibers each having a small diameter so that the fibers protrude by needle punching means. This makes it possible for edges of a large number of ridge regions arranged in parallel to each other to function as cleaning edges to clean a surface of an article to be cleaned effectively. Further, since the ridge regions have the predetermined width, an appropriate strength of the ridge regions can be secured to restrain the quantity of compressive deformation of the edge parts by a frictional force during cleaning. Thus, a high cleaning performance can be exhibited.

1 . (canceled) 
   
   
       2 . The cleaning cloth according to  claim 7 , wherein the thickness of regions in the nonwoven cloth, in which the ridge regions are not formed, is from 1 to 3 mm, the height of the ridge regions is from 4 to 6 mm, the interval between the ridge regions is from 4 to 8 mm, and the width of the ridge regions is from 3 to 6 mm. 
   
   
       3 . (canceled) 
   
   
       4 . The cleaning cloth according to  claims 2  or  7 , wherein the synthetic resin fiber is a polyester fiber, the fineness thereof is from 20 to 30 dtex, and the density of the nonwoven cloth is from 0.15 to 0.40 g/cm 3 . 
   
   
       5 . The cleaning cloth according to  claims 2  or  7 , wherein the sectional shape of the synthetic resin fiber is triangular or rectangular. 
   
   
       6 . The cleaning cloth according to  claims 2  or  7 , wherein the synthetic resin fibers are formed to have a sheath/core structure, and a core material is made of polyester and a sheath material is made of polyethylene having a lower melting point than that of the core material. 
   
   
       7 . A cleaning cloth, in which a large number of parallel ridge regions each having a predetermined width are formed at predetermined intervals in a nonwoven cloth made of synthetic resin fibers each having a small diameter so that the fibers protrude in a loop by needle punching means, and in middles of the ridge regions, narrower middle grooves are made along a ridge direction.
