DYEING APPARATUS FOR NATURAL INDIGO FOR PADDING DYEING MACHINE

摘要

PURPOSE: A dyeing apparatus of a natural polygonum indigo which uses a padding dyeing machine is provided to enable even dyeing treating an oxidation coloring process once again by reacting with oxygen in the water during a washing process in a washing unit and to prevent environmental pollution along with cost reduction by reducing a consumed amount of the water for dyeing. CONSTITUTION: A dyeing apparatus of a natural polygonum indigo dyeing apparatus, which uses a padding dyeing machine, forms a dyeing unit (20) at the back of a supplying unit (10). A dyeing unit makes even dying of a fabric, which goes through a dyeing chamber, achieved through oxidation coloring by repeating immersion into a polygonum indigo and exposure by composing an immersion roller. A washing unit formed at the back of an oxidation coloring unit (40) is capable of improving dyeing efficiency by making the fabric, which is oxidized and colored, pass through the washing water in a zigzag path by installing a washing roller (52) with a zigzag path in a washing chamber (51) in which the washing water (E) is filled. The washed fabric is dehydrated with vacuum going through a vacuum dehydration pipe (61) and the dehydrated fabric is wounded on a winding roller (63) which is positioned in an upper part of a drive roller (62).
