Abstract
An abrasive polypropylene meltblown web having a very light basis weight and thick fibers is made by depositing the fibers onto a substrate while in a semi-molten state.
Claims9
A layered abrasive web comprising a supporting layer and a meltblown abrasive layer thermally bonded together, said meltblown abrasive layer having a basis weight of from about 5 to about 25 grams per square meter and essentially consisting of fibers having an average fiber diameter of at least about 40 micrometers.
A method for making an abrasive web comprising meltblowing a polymer melt into bilers through a die tip in a semi-molten state onto a supporting web in other than a semi-molten staten and composed of elements which are dimensionally distinct from the melt-blown fibers state such that upon contact with the supporting web the meltblown fibers thermally bond to the supporting web.
