This study examined the dyeability and functionality of silk fabrics dyed using shiitake mushroom pins dis carded in large quantities on mushroom farms. FT-IR and UV-Vis spectral analyses showed that polyphenols and flavonoids were present in the hot-water extract of shiitake mushroom pins. Optimal dyeing conditions for silk fabrics were a dye concentration of 50% (v/v), dyeing temperature of 80˚C, dyeing time of 60 minutes, and dyebath pH of 5.3. The post-mordant method showed a greater effect on the increase in dye uptake and color change than the pre-mordant method. Unmordanted fabrics appeared as a YR Munsell color. Except for the Cu-mordant, all post-mordanted fabrics produced a Y Munsell color. The FE-SEM/EDX analysis confirmed that the natural iron solution and mud contained various metal ions. The Fe component was found to have the greatest effect on the dye uptake and color properties. The colorfastness of the unmordanted fabrics to washing, dry cleaning, rubbing, and perspiration was excellent (above grade 4), whereas light was grade 3–4. In the case of post-mordanted fabrics with a natural iron solution, the colorfastness to washing, wet rubbing, and light improved by 0.5 grades. For post-mordanted fabrics with mud, the colorfastness to light and sweat improved by 0.5 grades. The bacterial reduction rate for staphylococcus aureus in fabrics dyed with shiitake mush room pin extract was excellent at over 99.9%, the bacterial reduction rate for klebsiella pneumoniae was 98.1%, and the deodorization rate was excellent at 90%. These results indicate that shiitake mushroom pins can be used as a sustainable, functional natural dye.
