Using the new type auxiliary(K-1), dyeing experiment was done at the various dyeing conditions and the effects of auxiliary on the dyeing properties of acid milling dye for the silk fiber were dicussed. The results obtained were as follows; 1. The exhaust rate of acid milling dye was increased according to the auxiliary concentration at dyebath pH 7, But the increasing tendency of exhaust rate was decreased above auxiliary concentration 3% o. w. f.. 2. It was the same tendency of exhaust rate at dyebath pH 5, but the diffusion was more powerful at dyebath pH 7 than pH 5. 3. The decreasing ratio of exhaust rate according to dye concentration increasing was lower at auxiliary addition than auxiliary non-addition. 4. The exhaust rate curve according to increasing dyeing temperature showed the inflection point at auxiliary non-addition, but it was not observed in auxiliary addition. Consequently, it seems to be avoid that the occurrence of uneven dyeing at auxiliary addition.
