Abstract
In a method for continuously dyeing textile yarns (14), the yarns travel continuously in front of a succession of stations (15a, 15b, 15c) for applying dyes of different colors, each station applying a series of spots onto the yarns (14), so that each yarn includes a succession of spots forming a pattern extending over a certain length (L) of the yarn (14) and which is continuously repeated. The stations (15a, 15b, 15c) for applying the dye are commanded individually in order to corrupt the repetitiveness of the successive patterns. The method is useful for improving the quality of carpets obtained from textile yarns (14).

A method for continuously dyeing textile yarns (14), in which the yarns travel continuously in front of a succession of stations (15a, 15b, 15c) for applying dyes of different colors, each station applying a series of spots (A.sub.1, . . . B.sub.1, . . . C.sub.1, . . . ) onto the yarns (14) by means of a dye-spraying turbine (T1, T2, T3) driven rotationally by a drive motor (M1, M2, M3) about an axis which is parallel to the direction of travel of the yarns (14), so that each yarn includes a succession of spots forming a pattern extending over a certain length (L) of the yarn (14) and which is continually repeated, wherein the rotational speed (N) of the drive motor (M1, M2, M3) of each dye-spraying turbine (T1, T2, T3) is adjusted individually and independently of that of the other motors in order to corrupt the repetitiveness of the successive patterns and to avoid superposition of the spots.
A machine for continuously dyeing textile yarns (14) comprising a succession of stations (15a, 15b, 15c) for applying dyes of different colors, means for making the textile yarns (14) travel continuously in front of said application stations (15a, 15b, 15c), each application station comprising a dye-spraying turbine (T1, T2, T3) driven rotationally by a drive motor (M1, M2., M3) about an axis which is parallel to the direction of travel of the yarns (14), each turbine having at its periphery several holes (16) for the passage of the dye which are suitable for spraying a succession of spots (A.sub.1, . . . B.sub.1, . . . C.sub.1, . . . ) onto the yarns (14), the succession of application stations (15a, 15b, 15c) being adapted to form on each yarn a pattern of spots extending over a certain length (L) of the yarn (14) and which is continually repeated, wherein the application stations (15a, 15b, 15c) comprise means for individually adjusting the rotational speed (N) of the drive motor (M1, M2, M3) of each dye-spraying turbine (T1, T2, T3) and independently of that of the other motors in order to corrupt the repetitiveness of the successive patterns.
A method for continuously dyeing textile yarns (14), in which the yarns travel continuously in front of a succession of stations (15a, 15b, 15c) for applying dyes of different colors, each station applying a series of spots (A.sub.1, . . . B.sub.1, . . . C.sub.1, . . . ) onto the yarns (14) by means of a dye-spraying turbine (T1, T2, T3) driven rotationally by a drive motor (M1, M2, M3) about an axis which is parallel to the direction of travel of the yarns (14), so that each yarn includes a succession of spots forming a pattern extending over a certain length (L) of the yarn (14) and which is continually repeated, wherein the rotational speed (N) of the drive motor (M1, M2, M3 ) of each dye-spraying turbine (T1, T2, T3) is adjusted individually and independently of that of the other motors, in order to corrupt the repetitiveness of the successive patterns, and to modify the colors of the spots (A.sub.1, . . . B.sub.1, . . . C.sub.1, . . . ) in the successive patterns.
A machine for continuously dyeing textile yarns (14) comprising a succession of stations (15a, 15b, 15c) for applying dyes of different colors, means for making the textile yarns (14) travel continuously in front of said application stations (15a, 15b, 15c), each application station comprising a dye-spraying turbine (T1, T2, T3) driven rotationally by a drive motor (M1, M2, M3) about an axis which is parallel to the direction of travel of the yarns (14), each turbine having at its periphery several holes (16) for the passage of the dye which are suitable for spraying a succession of spots (A.sub.1, . . . B.sub.1, . . . C.sub.1, . . . ) onto the yarns (14), the succession of application stations (15a, 15b, 15c) being adapted to form on each yarn a pattern of spots extending over a certain length (L) of the yarn (14) and which is continually repeated, wherein the application stations (15a, 15b, 15c) comprise means for individually adjusting the rotational speed (N) of the drive motor (M1, M2, M3) of each dye-spraying turbine (T1, T2, T3) and independently of that of the other motors in order to corrupt the repetitiveness of the successive patterns, wherein said means for adjusting the speed (N) are suitable for varying the length (L) of the successive patterns, so that, in a series of successive patterns, their length varies continuously up to + or -20% of their mean length (L.sub.m).
