Abstract
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.
