An antistatic pile carpet having a relatively pliable primary backing and a tufted surface, said surface being comprised of fibers selected from the group consisting of polyester and polyamide fibers having grafted thereon from 1 to 5 percent by weight of a conductive polymeric salt of a polyethylenimine having a molecular weight of 200 to 10,000 and a sulfonic acid compound of the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are individually hydrogen or a lower alkyl radical having 1-3 carbon atoms.

Antistatic carpet

A flame-retardant pile carpet having a relatively pliable primary backing and a tufted surface, said surface being comprised of fibers selected from the group consisting of polyester and polyamide fibers having incorporated therein from 0.1 to 15 percent by weight of a compound selected from the group consisting of zinc oxide and zinc hydroxide, said fibers being bonded to said backing with a bonding substance comprising a latex material and a hydrate material, said latex material being selected from the group consisting of polymers and copolymers of vinylidene chloride, and said hydrate material being selected from the group consisting of aluminum hydroxide and hydrated aluminum oxide, the ratio by weight of said latex material to said hydrate material being within the range 1:2 to 1:4.5.

Flame retardant carpet

A flame-retardant polyamide fiber is prepared and made into a flame-retardant carpet. The polyamide fiber has incorporated therein from 1 to 15 percent by weight of zinc borate and from 1 to 15 percent of an organic halide which is substantially non-reactive with the polyamide except at temperatures above 300.degree. C. The flame-retardant fiber shows improved luster and improved colorfastness to light when dyed.

Flame-retardant polyamide fiber for use in carpets

A flame-retardant pile carpet having a relatively pliable primary backing and a tufted surface, said surface being comprised of fibers selected from the group consisting of polyester and polyamide fibers having incorporated therein from 0.05 to 15 percent by weight of a compound selected from the group consisting of antimony oxide and zinc borate, said fibers being bonded to said backing with a bonding substance comprising a latex material and a hydrate material, said latex material being selected from the group consisting of polymers and copolymers of vinyl chloride and vinylidene chloride, and said hydrate material being selected from the group consisting of aluminum hydroxide and hydrated aluminum oxide, the ratio by weight of said latex material to said hydrate material being within the range 1:2 to 1:4.5.
