A personal care article including a thermoplastic magnetic member. The thermoplastic magnetic member is formed of a thermoplastic material with magnetic particles dispersed therethrough. The 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. The magnetic particles are selected from the group consisting of magnetoplumbite-structure ferrite particles, rare-earth magnet particles, and mixtures thereof. The thermoplastic material may be disposed on a surface of a fibrous substrate. A surface of the thermoplastic magnetic member may be profiled. A second thermoplastic magnetic member may have an opposite magnetic polarity and a complementary surface profile such that the two thermoplastic magnetic members may be magnetically joined and mechanically interlocked when in a mated configuration.

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; andsaid 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. 2. The disposable absorbent article according to claim 1, wherein said closure system comprising at least one thermoplastic magnetic member comprises at least one matched pair of thermoplastic magnetic members comprising a first thermoplastic magnetic member and a second thermoplastic magnetic member, wherein said first thermoplastic magnetic member has a magnetic polarity opposite to a magnetic polarity of said second thermoplastic magnetic member, and wherein said first thermoplastic magnetic member and said second thermoplastic magnetic member are magnetically joined and mechanically interlocked when in a mated configuration. 3. The disposable absorbent article according to claim 1, wherein said disposable absorbent article is a disposable diaper. 4. A disposable absorbent article comprising a closure system comprising at least one matched pair of thermoplastic magnetic members comprising a first thermoplastic magnetic member and a second thermoplastic magnetic member, wherein the second thermoplastic magnetic member comprises an aperture, the first and second thermoplastic magnetic members each 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; andthe magnetic particles are selected from the group consisting of magnetoplumbite-structure ferrite particles, rare-earth magnet particles, and mixtures thereof,wherein the thermoplastic material is present in an amount of from about 10% to about 25% and the 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 first thermoplastic magnetic member has a magnetic polarity opposite to a magnetic polarity of the second thermoplastic magnetic member, and wherein the first thermoplastic magnetic member and the second thermoplastic magnetic member are magnetically joined and mechanically interlocked when in a mated configuration, andwherein the first thermoplastic magnetic member is inserted into the aperture of the second thermoplastic magnetic member when in the mated configuration. 5. The disposable absorbent article according to claim 4, wherein said disposable absorbent article is a disposable diaper.
