Beschreibung
Zusammenfassung:	The present invention provides an improved nonwoven abrasive product. The improved abrasive product has a porous, lofty web of multiple layers of coiled, autogenously bonded thermoplastic filaments, binder resin, abrasive granules and size resin. When porous, lofty web, before adding binder resin, abrasive granules or size resin, has a coil weight in the range of 17 to 28 g/24 in2 (1.097 to 1.808 kg/m2) and is variegated, and the coated porous lofty web exhibits a relatively high measured load/deflection value then the useful life of the abrasive product is greatly increased compared to abrasive products made from webs having lower coil weights and no variegation.
