Abstract: The permeability, Rf value, saline-alkaline resistance and compatibility of Levafix CA high light reactive dyes in mid-light primary colors were analyzed. The effect of multi-dyeing via pad dyeing process was compared. The fastness of pad-dyed fabrics was finally tested. Results showed that Levafix CA high light trichromatic reactive dyes exhibit good permeability, compatibility, synchronous coloring and dyeing stability, and its influences on saline and alkaline dyeing is consistent. It was suitable for color matching by pad dyeing, for the light fastness and perspiration-light fastness reached above 5 grade and 4 grade respectively and other fastnesses did not decrease.
