Claims
- 1. A saxony carpet having a backing and a tufted pile surface on said backing, said tufted pile surface including carpet fibers formed of a polymer blend comprised of:
- (a) from about 70 to about 99.85% by weight of a nylon polymer;
- (b) from about 0.05 to about 5% by weight of an amorphous polyamide miscible with the nylon polymer (a), and
- (c) from about 0.1 to about 35% by weight of an amorphous polymer immiscible with the nylon polymer (a) which is at least one selected from the group consisting of poly(phenylene oxides), polymethyl methacrylates, bisphenol A polycarbonates, polyethersulfones, polyarylethersulfones, polyphenylsulfones and bisphenol A polysulfones.
- 2. The saxony carpet of claim 1, wherein said nylon (a) is at least one nylon selected from the group consisting of nylon 6 and nylon 6,6.
- 3. The saxony carpet of claim 1, wherein said amorphous polyamide (b) is a copolymer of hexamethylenediamine, isophthalic acid (I) and terephthalic acid (T).
- 4. The saxony carpet of claim 3, wherein said isophthalic acid (I) and said terephthalic acid (T) are each present in an amount to provide a ratio (I):(T) of from 0.5:1 to 2:1.
- 5. The saxony carpet of claim 1, wherein said immiscible amorphous polymer (c) is a poly(phenylene oxide).
- 6. The saxony carpet of claim 5, wherein said poly(phenylene oxide) is modified by with an .alpha.,.beta.-unsaturated compound.
- 7. The saxony carpet of claim 6, wherein said .alpha.,.beta.-unsaturated compound is at least one selected from the group consisting of .alpha.,.beta.-unsaturated aliphatic mono-and dicarboxylic acids, .alpha.,.beta.-unsaturated aliphatic mono-and dicarboxylic esters, .alpha.,.beta.-unsaturated aliphatic mono-and dicarboxylic amides, .alpha.,.beta.-unsaturated aliphatic mono-and dicarboxylic imides, and aromatic vinyl monomers.
- 8. A saxony carpet having a backing and a tufted pile surface on said backing, said tufted pile surface including carpet fibers formed of a polymer blend comprised of:
- (a) from about 70 to about 99.85% by weight of nylon-6;
- (b) from about 1 to about 5% by weight of an amorphous copolymer derived from hexamethylenediamine, isophthalic acid (I), and terephthalic acid (T); and
- (c) from about 10 to about 25% by weight of an amorphous poly(phenylene oxide) polymer immiscible with the nylon-6.
- 9. A saxony carpet as in claim 8, wherein the amorphous copolymer (b) has a ratio of (I) to (T) of from about 0.5:1 to about 2:1.
- 10. The saxony carpet as in claim 8, wherein said amorphous copolymer (b) is present in an amount of about 2 wt. % or less.
- 11. A saxony carpet as in claim 8, wherein said poly(phenylene oxide) is modified by melt mixing with an .alpha.,.beta.-unsaturated compound.
- 12. The saxony carpet as in claim 1 or 8, wherein said carpet fibers comprise bulk continuous fibers.
- 13. The saxony carpet as in claim 1 or 8, wherein said carpet fibers have a denier in the range of 15 to 25.
