1. a process for making colorable filament comprising:
- (a) blending virgin polymer A and recycle polymer A to form a mixture; and
(b) forming the mixture into colorable mono-component filament that has a good colorability characteristic comparable to that of colorable mono-component filament formed from the virgin polymer A free of the recycle polymer A.

Abstract
A process for making colorable mono-component filament, and the colorable mono-component filament. A virgin polymer and a recycle polymer are blended to form a mixture, followed by forming the mixture into colorable mono-component filament. Achieved is a good dyeability characteristic for the colorable mono-component filament comparable to that of colorable mono-component filament formed from the virgin polymer free of the recycle polymer.

14. A process for making colorable filament comprising:
-
(a)blending virgin nylon and recycle nylon to form a mixture, wherein the virgin nylon and the recycle nylon are chosen so that the combined virgin nylon and recycle nylon in the mixture has one of (i) a range of sulfur from about 1000 ppm to about 2600 ppm, or (ii) a range of amine ends from about 33 meq/gm to about 71 meq/gm, and (b) forming the mixture into colorable mono-component nylon filament that has a good colorability characteristic comparable to that of colorable mono-component nylon filament formed from the nylon free of the recycle nylon.

26. A colorable mono-component nylon filament comprising virgin nylon and recycle nylon, and having a good dyeability characteristic comparable to that of colorable mono-component filament made from the virgin nylon free of the recycle nylon, and wherein the virgin nylon and the recycle nylon are chosen so that the combined virgin nylon and recycle nylon has one of (i) a range of sulfur from about 1000 ppm to about 2600 ppm, or (ii) a range of amine ends from about 33 meq/gm to about 71 meq/gm.
