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).
