Abstract:
1. A disposable absorbent article comprising a closure system comprising at least one thermoplastic magnetic member, said thermoplastic magnetic member comprising a thermoplastic material having magnetic particles dispersed therethrough, wherein said thermoplastic material comprises: a resin selected from the group consisting of polyolefins, thermoplastic elastomers, polyamides, polyacetals, polyethers, polyesters, polyurethanes, poly(meth)acrylates, and compatible mixtures thereof; and said magnetic particles are selected from the group consisting of magnetoplumbite-structure ferrite particles, rare-earth magnet particles, and mixtures thereof; wherein said thermoplastic material is present in an amount of from about 10% to about 25% and said magnetic particles are present in an amount of from about 50% to about 90%; wherein at least a portion of the thermoplastic material comprises a thermoplastic elastomer selected from the group consisting of styrenic block copolymers, metallocene-catalyzed polyolefins, polyesters, polyurethanes, polyether amides, and combinations thereof; wherein said thermoplastic magnetic member is deposited onto the surface of said disposable absorbent article by a rotogravure printing process, wherein the thermoplastic magnetic member partially penetrates into and combines with the disposable absorbent article.
