  • Process for imparting hydrophilicity to fabric
    Patent number: 4463036
    Abstract: A process for imparting hydrophilicity to fabric which comprises treating the fabric with a composition comprising a copolymer of an N-(oxymethyl)-acrylamide grafted onto a poly(oxyalkylene) backbone and an acid catalyst to facilitate cross-linking of the graft copolymer on the fabric surface and drying said fabric at a temperature sufficient to cure the graft copolymer.
