Title:	Cabled or wrapped, stuffer box crimped yarn and method of producing the same
Abstract:	A stuffer box crimped yarn of lengthwise uniformity in appearance is produced by twisting together or, more specifically, cabling at least three multifiliment ends, at least one of the ends being of a different color, initial twist or initial texture from at least one other of the ends, or by twisting together, that is, wrapping, two stuffer box crimped multifilament ends, at least one of the ends having an initial twist, the ends being of different colors, initial twists or initial textures.

Patent Claims:	1. Method of producing a cabled, stuffer box crimped yarn of lengthwise uniform appearance comprising twisting together in one sense at least a first stuffer box crimped multifilament end and a second stuffer box crimped multifilament end and twisting the twisted together ends together in the opposite sense with at least a third stuffer box crimped multifilament end, at least one of said ends being of a different appearance from at least one other of said ends. 2. Method according to claim 1, in which the total denier of all the twisted together ends is about 2000 to about 20,000. 3. Method according to claim 2, in which each twisting is about 0.5 to about 10 turns per inch, the different appearance comprises different initial twist, the amount of twist in any pre-twisted end is about 0.5 to about 10 turns per inch and the final yarn contains filaments having a twist of about 0.5 to about 10 turns per inch in one sense and filaments having a twist of about 0.5 to about 10 turns per inch in the opposite sense. 4. Method according to claim 3, in which all of the filaments are of about 3 to about 50 denier per filament. 5. A cabled yarn of lengthwise uniform appearance comprising at least three stuffer box crimped multifilament ends twisted together and containing respective sets of filaments twisted in opposite senses and at least one of the ends being of a different appearance from at least one other of the ends. 6. Yarn according to claim 5 having a total denier of about 2,000 to about 20,000. 7. Yarn according to claim 6, in which all twist is of about 0.5 to about 10 turns per inch. 8. Yarn according to claim 7, in which all of the filaments are of about 3 to about 50 denier per filament. 9. Method of producing a wrapped, stuffer box crimped yarn of lengthwise uniform appearance comprising twisting together two stuffer box crimped multifilament ends, at least one of the ends having an initial twist, the ends being of different appearance. 10. Method according to claim 9, in which also the second stuffer box crimped multifilament end has an initial twist. 11. Method according to claim 9, in which the total denier of the twisted together ends is about 2000 to about 20,000. 12. Method according to claim 11, in which all twist is of about 0.5 to about 10 turns per inch. 13. Method according to claim 12, in which all of the filaments are about 3 to about 50 denier per filament. 14. A wrapped yarn of lengthwise uniform appearance comprising two stuffer box crimped multifilament ends twisted together at least one of the ends containing twist in addition to that imparted by the twisting together of the ends and the ends being of different appearance. 15. Yarn according to claim 14, having a total denier of about 2,000 to about 20,000. 16. Yarn according to claim 15, in which all twist is of about 0.5 to about 10 turns per inch. 17. Yarn according to claim 16, in which all of the filaments are of about 3 to about 50 denier per filament.
