Claims
- 1. A carpet which comprises a multilobal composite filament having reduced stainability, said filament comprising a polyamide core having an amine end group content of from about 5 to about 45 meq/kg, and a hydrophobic polymer sheath surrounding said core, said hydrophobic polymer being selected from the group consisting of aromatic polyesters, aliphatic polyesters, polyethylene, polymethylpentene, polybutene, and polymethyl butene, and wherein the weight ratio between said core and said sheath is from about 2:1 to about 10:1.
- 2. The carpet according to claim 1, wherein said multilobal filament is a trilobal composite filament.
- 3. The carpet as in claim 1, wherein the multilobal composite filament has a trilobal, tetralobal, pentalobal or hexalobal shape.
- 4. The carpet as in claim 1, wherein the polyamide is selected from the group consisting of nylon 6, nylon 6/6, nylon 6/9, nylon 6/10, nylon 6/12, nylon 6T, nylon 11, nylon 12, copolymer thereof and mixtures thereof.
- 5. The carpet as in claim 1, wherein the polyamide is nylon 6 or nylon 6/6.
- 6. The carpet as in claim 1, wherein the hydrophobic polymer is selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, poly(1,4 cyclohexylene dimethylene terephthalate), polyethylene oxybenzoate, polyglycolide and polypivalolactone.
- 7. The carpet as in claim 1, wherein the core is nylon 6 and the sheath is polyethylene terephthalate.
- 8. The carpet as in claim 1, wherein the core is nylon 6 and the sheath is polybutylene terephthalate.
- 9. The carpet as in claim 1, wherein the multilobal filament is hollow.
- 10. The carpet as in claim 1, wherein the weight ratio between the core and the sheath is from about 1:1 to about 10:1.
- 11. The carpet as in claim 1, wherein the weight ratio between the core and the sheath is from about 2:1 to about 5:1.
