Beschreibung
Zusammenfassung:	The present invention relates to a nylon yarn of a finely dispersed melt blended polymer alloy having i) a polyamide component selected from polyhexamethyleneadipamide, polycaprolactam and mixtures thereof, and ii) a nylon 11 component; wherein the polyamide component is the major component by weight of the total melt blended polymer and wherein the polyamide component has a viscosity of about 2.6 IV or more as measured in 96% sulfuric acid. The resulting nylon yarn shows improved bleach resistance. The present invention also relates to processes of producing the yarn and nylon carpets comprising the yarn described above.
