<p>A reinforcing material suitable for use in footwear stiffeners, characterised in that the material comprises consolidated melt-spun fibres of hot-melt adhesive, e.g. polyester melting point about 60 °C, combined with bulk fibres, e.g. of 20 mm to 100 mm in length, in a ratio of adhesive fibres to bulk fibres between 20:80 and 80:20 by weight, said fibres having been entangled prior to consolidation under pressure and heat.</p> |
