%X Current methods of fabric dyeing have a significant negative effect on the environment via toxic effluent emissions, high water usage, and high energy consumption. We demonstrate, for the first time, low-energy inkjet printing of an ecofriendly and biodegradable pigment derived from widely available spalting fungi with synthesis by-products that are fully biodegradable. Vivid and stable coloration is achieved on polyester and cotton using benign acetone-based and ethanol-based biopigment inks, with no liquid effluent or runoff, and without any synthetic dyes or mordants. We investigate the influence of fabric type, solvent type, and the number of printing passes on the color type, intensity, and uniformity, pigment crystallization, and environmental stability. Greater spatial definition of the printed pigment in inkjet printing effects greater crystallization and more vivid and uniform coloration as compared to drop-casting, the primary method used till date to color fabrics with such fungal biopigments. pH-driven interactions between the fabric, solvent, and biopigment cause solvent-driven changes in color type (from bluish to reddish) and fabric-governed changes in color intensity. The impact of our findings on minimizing the environmental impact of fabric dyeing is discussed.

%X In this study, pigments In this study, pigments from three species of pigmenting fungi, Chlorociboria aeruginosa (xylindein, green), Scytalidium cuboideum (draconin red, red), and Scytalidium ganodermophtherum (yellow), were used to dye multi-fabric test strips. Tests for color stability and tests for colorfastness to washing with and without bleach, and to perspiration, were conducted. Color readings were taken using a colorimeter, and color differences were statistically determined based on overall color change as calculated using the CIE L*a*b* color space. The results indicated that all three pigments were stable over time, indicating that these pigments can be used for fabric dyeing, eliminating the need for additional chemicals or heat as is required for traditional fabric dyes. Xylindein and draconin red exhibited good colorfastness to washing, and xylindein good colorfastness to perspiration. These results indicate that xylindein shows good potential as a dye for garment fabrics, and draconin red shows good potential as a dye for second-layer garment fabrics.

%X A growing interest in the use of naturally produced pigments for textile dyeing has led to increased efforts towards the identification of such pigments that are less toxic, more sustainable, and more stable over time than currently used synthetic compounds. This work utilised various concentrations of green, red, and yellow pigments extracted with dichloromethane from the wood-staining fungi Chlorociboria aeruginosa, Scytalidium cuboideum, and S. ganodermophthorum, respectively, for the effective dyeing of bleached cotton, spun polyamide (nylon 6.6), spun polyester (Dacron 54), spun polyacrylic, and worsted wool. All three pigments utilised in this study show significant potential for use as textile dyes. Colour changes suggested that drip application methods were superior to submersion using dichloromethane. Colour changes as compared with the untreated fabrics were most significant on polyester, which is likely due to increased levels of polymer swelling in polyester exposed to dichloromethane.
