Abstract A durably soil-resistant carpet is provided which comprises a plurality of organic fibers having thereon a normally solid coating comprising (a) at least one phase of a water-insoluble addition polymer derived from a polymerizable ethylenically unsaturated monomer free of non-vinylic fluorine, the polymer having at least one major transition temperature higher than about 45° C. and a solubility parameter of at least about 8.5, and (b) at least one phase of a water-insoluble fluorinated component containing a fluoroaliphatic radical of at least 3 carbon atoms, the fluorinated component having at least one major transition temperature higher than about 45° C.; and at least one of said phases being a continuous phase. Novel compositions and processes for the treatment of carpets to render them durably soil resistant are also provided.
A composition suitable for the treatment of carpets to impart durable soil-resistant and stain repelling properties thereto, said composition comprising at least 0.1% solids in a liquid medium said solids comprising: a. a water-insoluble addition polymer derived from polymerizable ethylenically unsaturated monomer free of nonvinylic fluorine, said polymer having at least one major transition temperature higher than about 45° C. and a solubility parameter of at least about 8.5, and b. a water-insoluble fluorinated component containing fluoroaliphatic radical of at least 3 carbon atoms, said fluorinated component containing at least 25 percent by weight of fluorine in the form of fluoroaliphatic radicals and having at last one major transition temperature higher then about 45° C.; said composition being substantially free of polymers not having a major transition temperature higher than about 45° C.
