PROCESS AND APPARATUS FOR COLORING TEXTILE YARNS

摘要

Method and apparatus (10) for producing a textile yarn (12) so that one surface (b) of the yarn (12) exhibits a visually perceptive darker color hue when compared to another surface (a) of the yarn (12). The yarn surfaces are coated with a colorants-containing liquid (eg. a dye- or pigment-containing liquid) in a bath (16), and then dried by a drum (22) to effect a drying rate differential between the one and another surface (b and a, respectively) in order to cause the colorants to migrate towards the faster-drying surface (b) to a degree sufficient to achieve the darker color hue thereon. Twisting of the produced yarns during packaging and/or weaving will thus create a woven textile fabric having randomly distributed color variations to achieve a visually pleasing striated, tone-on-tone or heather fabric appearance.
