A method of imparting acid dye stain resistance to polyamide substrates having improved durability of the stain resistance to detergent washings comprising treating the polyamide substrate with an effective amount of a mixture of phenyl vinyl ether/maleic diacid copolymer and 2-(4-hydroxymethyl-phenoxy)-ethyl vinyl ether/maleic diacid copolymer, wherein the phenyl vinyl ether/maleic diacid copolymer is the stain resist agent, and the 2-(4-hydroxymethyl-phenoxy)-ethyl vinyl ether/maleic diacid co...

Polymeric carpet and a method of making and recycling such carpet, the carpet having fibers, backing and extruded adhesive all of completely recyclable materials, the recycling being accomplished in one melting step, without a separation step.

A sanitary napkin comprising a topsheet comprising a plurality of discrete tufts of fibrous material, wherein the topsheet has a density of less than 0.027 g/cc under a load of 0.004 psi, and a density of less than 0.068 at a load of 0.23 psi.

Disclosed is a precoat resin dispersion having a solids content from about 63% to about 69% comprising (1) at least one resin having a Ring and Ball softening point from about 60.degree. C. to about 100.degree. C. in an aqueous dispersion having a solids content from about 53% to about 58%; (2) at least one water-soluble polymer; (3) at least one cationic resin; and (4) water. The precoat resin dispersion is useful in the manufacture of tufted carpets, especially carpets manufactured with carbox...

A process for improving the end-use properties of tufted floor coverings, which comprises, in the manufacture of tufted floor coverings, mixing the dispersions or latexes which are necessary for the precoat and/or for the second coat, before their compounding, with a fluorosurfactant of the formula where Rf denotes a radical of the formula C.sub.6 F.sub.13, C.sub.8 F.sub.17, C.sub.10 F.sub.21 or C.sub.12 F.sub.25, R denotes a group of the formulae ##STR1## M and M' denote sodium, potassium or NH...

Carpets having a primary backing and a pile consisting essentially of polyamide fibers stitched into the primary backing are described. The fibers are characterized in being stain resistant and the backing is characterized in being impervious to water. The carpet is easy to maintain since its fibers are stain resistant and water can be used to clean the carpet without fear of the water penetrating the backing and being absorbed by the padding, a situation which leads to rotting of the carpet and...

A playing field surface for active running and body contact type sports, such as football and the like, is formed of a stabilized, flat base surface covered by an underpad, over which is laid a synthetic pile fiber carpet. A covering of sand-like granules is applied upon the carpet to substantially fill the spaces between the fibers. The underpad is made of reclaimed rubber, sliver-like small particles which are bonded together into a thick, water pervious mat. The lower surface of the underpad ...

Carpets having stain resistant pile fibers and a backing that is substantially impervious to water are described. The impervious backing prevents water from passing through the carpet and into the underpad where its presence causes rotting and mildewing of the underpad and other carpet components. The impervious backing also permits washing of the carpet with generous amounts of water without wetting the underpad.

Carpets having stain resistant pile fibers and a backing that is substantially impervious to water are described. The imperviousness of the backing prevents water from passing through the carpet and into the underpad where its presence causes rotting and mildewing of the underpad and carpet components, and thus, permits the carpet to be washed with generous amounts of water without wetting the underpad. Also, aqueous substances which spill onto the carpet will not penetrate the carpet and wet th...

Disclosed is a carpet having a base fabric, pile yarns tufted to the base fabric and a backing layer covering a back surface of the base fabric. The light resistance of the dyed carpet and the anti-deteriorative properties of the pile yarns can be improved by covering portions of the pile yarns which extend into the backing layer with a resinous material containing finely divided carbon black.
