A method for making a multiple layer substrate comprising the steps of: forming a earner substrate; depositing an air laid layer comprising natural fibers on top of the earner substrate; wetting the air laid layer with a source of low pressure water; hydro entangling the air laid layer with the earner substrate to form an integrated substrate. In another aspect a low-density cleaning substrate with a basis weight of less than 100 gsm, Is formed, which comprises at least one layer of a earner web and at least one layer comprising an air laid cellulosic material which are hydroentangled together to form an integrated substrate. The substrate may be a pre-loaded wipe, which is either moistened by a consumer prior to use or moistened prior to packaging. The composition loaded onto the substrate may contain dry and/or liquid compositions preferably for cleaning hard or soft surfaces. |
