A wince dyeing machine has many practical merits, so it is widely used in dyeing works. However, it also has demerits : necessity of some manual procedure and occurence of ocassional dyeing specks. The purpose of this research is to improve these points. For reducing the manual procedure, a system which feeds liquid dye into liquid auxiliary was planned. For the prevention of dye specks, a new and simple circulation system was approved. The results of the experiment will show that the proposed system is effective in practical production.
