Abstract
The present invention relates to a nonwoven substrate suitable for use as a cleaning sheet having density of no more than 0.15 g/cm3 and comprising at least one fibrous web, said substrate comprising at least one first region and at least one second region wherein said second region comprises protruding elements and is capable of greater geometric deformation than said first region. The present invention also relates to the use of said substrates as cleaning sheets, a process of cleaning soiled surfaces with said substrates and a method of making said substrates.
