| 摘要 |
The present invention is directed to a method for making a multiple layer substrate comprising the steps of: (1) forming a carrier substrate; (2) depositing an air laid layer comprising natural fibers on top of the carrier substrate; (3) wetting the air laid layer with a source of low pressure water; (4) hydroentangling the air laid layer with the carrier substrate to form an integrated substrate. Another aspect of the present invention is the creation of a low-density cleaning substrate with a basis weight of less than 100 gsm, which comprises at least one layer of a carrier 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.
