Claims
- 1. A fiber comprised of a polymer blend comprising:
- a) from about 70 to about 99.85% by weight of a polyamide;
- b) from about 1 to about 5% by weight of a copolymer miscible with the polyamide a) 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 polyamide a).
- 2. The fiber of claim 1, wherein said polyamide a) comprises nylon 6 or nylon 6,6.
- 3. The fiber of claim 1, wherein the (I) to (T) ratio ranges from 0.5:1 to 2:1.
- 4. The fiber of claim 1, wherein said poly(phenylene oxide) is modified by melt mixing with an .alpha.,.beta.-unsaturated compound.
- 5. The fiber of claim 1, wherein the fiber comprises a bulk continuous filament.
- 6. The fiber of claim 5, wherein the filament has a denier in the range of 15 to 25.
- 7. The fiber of claim 1, wherein the amount of amorphous polymer miscible with the polyamide is about 2 wt. % or less.
- 8. A melt-spun fiber which consists essentially of a fiber-forming polymer blend comprising:
- 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. The fiber according to claim 8, having a denier in the range of from about 6 to about 35 denier/filament.
