摘要:
An abrasive wipe includes a spunbond layer that forms a first outer surface of the wipe, a meltblown layer positioned over the spunbond layer so as to form an inner layer of the wipe and an abrasive layer positioned over the meltblown layer so as to form a second outer surface of the wipe. The spunbond layer, the meltblown layer and the abrasive layer are bonded together in a single bonding step, and, in an exemplary embodiment, the abrasive wipe has an MD tensile strength of at least 700 g/cm and a CD tensile strength of at least 500 g/cm.
