Abstract
Abstract A curable fabric member comprising first and second uring reactants in elongate, preferably extruded, form. The reactants may be coextruded or sequentially extruded to form a single filament, or may be provided as separate staple fibres incorporated in a spun yarn, or as separate continuous filaments assembled into a multi-filament yarn.
