  • Patent number: 3983278
    Abstract: A process for improving the abrasion resistance of a pile surfaced material comprising fibrils or tufts of a thermoplastic material integrally formed with a sheet of the thermoplastic material said sheet having been bonded to a backing substrate by melting of the thermoplastic material, said process comprising subsequently heating the pile surfaced material from the substrate side to a temperature such that and for such a time that softening of the thermoplastic occurs but no substantial collapse of the pile occurs.
