Abstract
A fastening component of a separable fastener has some portion that is necessary for its fastening function, such as the hooks, the base to which the hooks are attached or a substrate that is used for another purpose, comprised of a magnetically attractive constituent. Another portion of the fastening component is comprised of a magnetically inert constituent. The fastening element may be the hook portion or the loop portion of a typical fastener. The fastening elements and the base may be unitary, or of different precursors, such as in a woven fastener component. The magnetically inert constituent may comprise a polymeric plastic or a thermoplastic elastomer. The magnetic attractant may impregnate the magnetically inert constituent, or it may coat or be coated by the magnetically inert constituent. The magnetic attractant may comprise a metal powder. The metal may be selected from the group consisting of iron powder. The magnetic attractant may be an organo-iron or a rare earth metal. In a woven fastener, either the base structure or the hooks may include the magnetic attractant, or both may do so.
The material that forms the hooks may be entirely of a magnetically attractive material, with the material that forms the woven base being magnetically inert. Rather than the magnetically attractive material being incorporated into the fastening elements or the base, it may be incorporated into the substrate that is formed from a precursor element that is separate from the base, and that is joined to the base.
The material that forms the hooks may be entirely of a magnetically attractive material, with the material that forms the woven base being magnetically inert. Rather than the magnetically attractive material being incorporated into the fastening elements or the base, it may be incorporated into the substrate that is formed from a precursor element that is separate from the base, and that is joined to the base.
