  • This study aimed to identify mordant effects of Chestnut hulls. The color of post and pre-mordanted fabrics were measured in terms of H, V, C, $L^*$, $a^*$, $b^*$, and K/S values. In addition, color fastness and antimicrobial activity were evaluated. The pre-mordant concentration of Chestnut hulls for cotton, mercerized cotton and silk was optimized to 50% (o.w.f.) and 70% (o.w.f.), respectively. Post-mordant concentration of Chestnut hulls of mercerized cotton, silk and cotton was optimized to 50% (o.w.f.) and 90% (o.w.f.), respectively. The hue of fabrics was influenced by mordant methods, such as pre-mordant and post-mordant, slightly. Wet cleaning fastness of pre-mordanted cotton and mercerized cotton fabrics was higher than that of post-mordanted fabrics. The wet cleaning fastness of silk fabrics was not affected by the mordant method, and their fastness were proved to be excellent. The dry cleaning fastness of post-mordanted cotton fabrics was higher than that of pre-mordanted cotton fabrics. The dry cleaning fastness of mercerized cotton and silk was proved to be excellent regardless of mordant methods. The antimicrobial activity of Oenothera odorata jacquin dyed fabrics and Chestnut hulls mordanted fabrics was proved to 99.9%, and their excellent antimicrobial activity remained after wet and dry cleaning.

  • The natural dyestuff(chestnut dye) was manufactured from chestnut hulls by boiling in 0.5 NaOH solution and powdering in freeze dryer. To investigate the dyeability and color fastness, cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured chestnut dye. Dyeing operation was carried in acidic dyebath of pH 4-5 because the chestnut dye is anionic. Dyeabilities on wool, silk and nylon fabrics were good, especially nylon fabrics were dyed deeper than others. But dyeability on cotton fabrics was not good. All the dyed fabrics showed excellent color fastness to crocking. Color fastness to laupdering of them were moderate to good. Also light fastness of them were moderate to good except nylon. The light fastness of dyed nylon fabrics was as poor as grade 1. But they could be improved to grade 4 by aftertreatment with gallic acid.

  • Nylon fabrics and stocking were dyed with artemisia dyeing solution, dyed with the natural dyestuffs that were manufactured from chestnut hulls by boiling in 0.5% NaOH solution and powdering in freeze dryer, and dyed with gromwell dyeing solution. Dyeabilities on nylon fabrics and stocking were good because of being amine group. All the dyed fabrics & stocking showed excellent in color fastness to laundering, and as poor as grade 1 to light fastness. But Light fastness of them could be improved to grade 3 or 4-5 by treatment with gallic acid and by repeated dyeing. Antimicrobial activities of the fabrics dyed with artemisia and gromwell against Staphylococcus aureus and Candida albicans were excellent in the aspect of bacteriostatic and fungistatic. There were not any distinct differences between mordant and non-mordant fabrics.
