A system for in-line treatment of at least one thread is provided. The system is configured to be used with a thread consuming device and comprises a treatment unit having a plurality of nozzles arranged at different positions relative the at least one thread, said at least one thread being in motion in use, each nozzle being configured to dispense one or more coating substances onto the at least one thread when activated; and at least one thread engagement device configured to rotate the at least one thread along its longitudinal axis as the at least one thread moves through said treatment unit.

A welding process may be configured to convert a substrate into a welded substrate by applying a process solvent to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may be configured as an ionic-liquid based solvent and the welded substrate may be a congealed network after the process solvent has been adequately swollen and/or mobilized the substrate. A welding process may be configured such that individual fibers of a substrate are not fully dissolved such that material in the fiber core may be left in the native state by controlling process variables. The welding process fibers may have a tenacity 10% or 20% greater or a diameter 25% less than that of a cellulosic-based yarn substrate.

The present invention relates to a device for dyeing a moving yarn that comprises a liquid dye supply line, a first nozzle positioned above the yarn and configured to deposit dye on a first surface of the yarn, a second nozzle positioned above the yarn and configured to deposit dye on a second surface of the yarn corresponding to a surface opposite the first surface relative to the axis of the yarn, a synchronization mechanism for actuating the nozzles as a function of the movement of the yarn such that, between the first and the second nozzle, the yarn is able to pivot axially under the effect of the gravity of the dye deposited by the first nozzle.

A system for in-line treatment of thread for use with a thread consuming device is provided. The system includes a treatment unit having a plurality of nozzles arranged at different positions relative the thread, said thread being in motion in use, each nozzle being configured to dispense one or more coating substances onto the thread when activated; and a control unit configured to activate at least two of the nozzles to dispense the coating substance at different circumferential positions of the thread when the thread twists along its longitudinal axis.
