Abstract

See full text

Pet pads contain insecticide and have at least one layer comprising a mixture of thermoplastic and other fibers. This latter layer may be thermobonded together and then densified along at least a section of the eventual peripheral edge margin of a pet pad to be formed from the material. By including insecticide in the mixture prior to thermobonding, the insecticide is fixed in the pad during thermobonding. Thermoplastic material-containing cover sheets may also be secured to the core and densified along the periphery of the pad. The entire eventual peripheral edge margin of the pet pad is typically densified. The densified edge acts as a partial liquid barrier and also helps retain the insecticide in the pad, especially if the insecticide is not fixed by thermobonding.
