  2. Process Description
    1. The process consists of indigo dyeing and sizing as preparation for the weaving process.
    2. The machine has 2 creels at the entry, where 16 warped cylinders are positioned in one and 14 in the other.
    3. The material passes through a desizing box to remove impurities from the raw material and previous processes, improving dyeing quality.
    4. The process continues in the washing boxes to remove traces of the desizing process.
    5. After washing, the dyeing process begins in 8 boxes (which can be lifted mechanically for easier maintenance).
    6. The material then goes through the pre-drying system before reaching two sizing boxes for warp sizing (roller width 1800 mm, squeeze rollers covered with rubber).
    7. Finally, the material passes through the dryer and the accumulation system before reaching the end of the process at the machine’s head, where the dyed and sized warp is wound onto cylinders, ready for weaving.
