Abstract

A fabric mold liner includes a flexible fabric substrate and bounded regions of cured binder encapsulating fibers of the fabric substrate and carrying magnetically attractable particles. A liquid containing ferrous particles in suspension in a binder is deposited on the substrate in discrete, selected regions arranged to correspond to magnetic liner retention points in a mold cavity. The mold liner is used in molding a foam article. The liner is inserted into a mold cavity with the liner positioned such that the bounded regions carrying the binder align with magnetic liner retention points of internal surface. A foamable resin is introduced into the mold and is caused to expand to fill the mold cavity and cover an exposed surface of the liner, such that the liner becomes bonded to, and becomes a part of, a foam body formed by the resin.
