    (54) Wiping article


    (57) A process for making a wiping article comprises distributing a heat-sealable, preferably meltable, material (36) such as polyethylene over at least one of two fibrous substrate layers (22,28), bringing the layers together so that the heat-sealable material (36) is at the interface between them, and also sandwiching surfactant (40) between the two layers. Energy is supplied to bond the two layers together but the heat-sealable material forms a discontinuous coating of one or both layers which are therefore bonded at a plurality of positions (42) distributed over the interface area. Hence the resulting article is water-permeable and the s urfactant (40) can be released progressively when the article is wetted.
