This study aimed to: describe the value of color fastness to washing by using five types of detergent namely cream, powder, bar, liquid, and Sapindusrarak on Tan written batik cloth with naphthol dyes; determine the effect of the detergent types on the color fastness; and find out the best type of detergent according to its composition for washing batik with naphthol dyes. This was true experimental research with the AXB factorial design in which A is the Tan batik cloth, and B is the factor of washing treatment with five detergent types. To collect the data, the researchers employed the probability sampling technique, which is asimple random sampling technique. Also, they tested the color fastness in the washing processes carried out by the examining team at the Batik and Craft Center with procedures and calibrated tools.The data were analyzed using a non-parametric analysis, namely, a Kruskal-Wallis test. The color fastness test of Tan batik cloth washed using five types of detergent produces a good average value of 4- 4.5. The result of the difference test on thecolor fastness to washing and staining is p 0.406> 0.05. It means there is no significant difference becausethe detergents have the same composition, i.e., an anionic surfactant.The detergent with the best composition is Sapindusrarak , because it contains saponin as a natural surfactant. People can use detergents to wash batik by selectingthe composition of lauryl alkyl benzene sulfonate as a soft substance.
