Quality Improvement of ABBS Hand Writing Batik Production through Standardization of Natural Dyeing using Water Guava and Mango Leaves

Dyeing standardization in the production of ABBS SMEs natural dye hand writing batik has been done. A series of stages of pre-treatment, dyeing and fixation have been determined to obtain the desired shades, color intensity and fastness. Optimizing the quality of dyeing is done by washing mori fiber using Turkey Red Oil (TRO) and mordanting using alum and soda ash. The dyeing is done by pre-mordanting method using natural dyes from water guava and mango leaves. To avoid loss of color, especially in the “lorod”(dyes resistrelease)stage, fixation is applied using alum, lime and iron (II) sulfate. The overall standardization in the production of natural dye batik produced by ABBS SMEs resulted in the appearance of brown to black shades with a color intensity of 73.84%-93.54% and fastness on a scale of 2-4 on dyeing using water guava leaf extracts and the appearance of dark and light brown to bluish shades with a color intensity of 79.89%-97.06% and fastness on a scale of 3-4 on dyeing using mango leaf extract. Overall, mango leaf extract produces better dyeing quality on ABBS hand writing batik products. Keywords—Batik, SMEs, ABBS, natural dye
