Acid dyes applied to Nylon fibers have a tendency to dye at the point of initial contact. The rapid reaction between the dye and the fiber at the point of initial contact can cause an uneven appearance or coloration to develop in the dyed fiber. This problem can be exacerbated when several dyes are used to produce a desired shade on the fiber, typically compounding the uneven coloration problem. In addition, the dyes may react at different rates to produce a separation of colors on the fiber. To alleviate this problem, a variety of materials, so-called “dye-leveling agents”, have been used to produce a level dye application. This research mainly explores the influence in dyeing behavior when applying different EO number of leveling agents with acid dyes in dip-dyeing (immerse dyeing) processes of Nylon fabrics. The results show that the lower EO number (m, n =15mole) of leveling agents can get the higher retarding effect, and the higher EO number (m, n=30mole) of leveling agents can get well migration effect.
