【 摘 要 】

Fungi can be used as an alternative source of natural dyes for thetextile industry. This research was conducted using mixed Aspergillus and Paecilomyces. The physical and chemical properties of the fungal dye were tested using 1% w/v of detergent for 15 minutes. Filtrate color and colors range developed on dyed materials were measured by RHS color chart. Of six different mordants tested, alum gave a brighter color than other mordants, so alum used for further research. The optimum mass of the fungal dye was adsorbed about 0.0023 g without mordant and the color was 82A purple-violet, while alum gave the optimum mass of the fungal dye adsorbed of 0.0013 g, which with 82C purple-violet color. Percentage the fungal dye absorption on cotton cloth without mordant was 9.6276%, while alum gave the fungal dye absorption of 3.6068%. Cotton cloth mass reduction after soaking in adetergent solution of the dyed cotton cloth using the fungal dye without mordant was 0.0036 g and the color was 88A violet, while alum gave the fungal dye reduced of 0.0018 g, which with 88C violet color. The obtained result showed dyes produced by mixed fungi could dye cotton cloth and resistant to detergent solution.
