Apparatus and method for the continuous wet treatment of yarns, particularly for their mercerization under tension

摘要

A continuous treatment system of yarns with process fluids, particularly for mercerization, wherein a bundle (4) of threads (1) to be treated is put into the reaction with a Venturi nozzle (12) activated with process fluid, which entrains the bundle (4) of yarn with it, and with a swirl distributor (13) in the J-shaped treatment reactor (11), having -an inner saddle-shaped guide surface (79) for the downward and upward movement of the yarn in the process fluid bath.
