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.

This study examines the effects of Evening primrose on colors, color fastness, and the antimicrobial activity of dyed fabrics. The results are as follows. The dyeing conditions of Evening primrose on cotton and mercerized cotton were optimized at $50^{\circ}C$, 60 minutes, and 200% (o.w.f.). In addition, Evening primrose dyeing on silk was determined at $90^{\circ}C$, 60 minutes and 200% (o.w.f.). The pre-mordant concentration of chemicals of cotton, mercerized cotton and silk was optimized at 1% (o.w.f.). The post-mordant concentration on mercerized cotton, silk and cotton was determined at 1% (o.w.f.) and 3% (o.w.f.), respectively. The mordant methods (such as pre-mordant and post-mordant) were slightly affected on the hue of dye-fabrics. Wet cleaning fastness of cotton was improved by post-mordant; otherwise, the wet cleaning fastness of mercerized cotton and silk was improved by a pre-mordant. The dry cleaning fastness of cotton and silk was excellent regardless of mordant methods. The dry cleaning fastness of mercerized cotton was improved by a post-mordant compared to a pre-mordant. The antimicrobial activity of Evening primrose-dyed fabrics was shown at 99.9%. The excellent antimicrobial activity of dyed fabrics remained after the mordant as well as wet and dry cleaning.

In this study, The mixture of three kinds of pre-treatment agents, Carboxymethyl cellulose sodium salt(CMC), Sodium alginate and Dextrin, have been prepared for the better coloration of digital textile printing. To get sharpness of outline during digital printing process, the optimal formulation is the CMC and Sodium alginate mixture 1:1 ratio by volume. Cyan, Yellow, and Black colours are excellent on the Sodium alginate mixtures. But, Magenta is excellent in the CMC and Dextrin mixture. Sharpness and printability are closely related to viscosity of the mixture. The most optimal sharpness of outline achieved with a consideration of coloring, and field operations account for production when the viscosity of the mixed pre-treatment agent approximately is 10~13 cSt. Change in shade and staining of wash fastness for all the treated samples with the mixtures rated 4-5 grade. Both dry rubbing fastness to shade change and staining are good in the treated samples, whereas wet rubbing fastness rated 2-3 grade. To improve wet rubbing fastness, the Sodium alginate and Dextrine mixture, which rated 3-4 grade for Black color, is applicable. With exception of 3 rating to black color, Light fastness is 4 rating for the remaining three colors in the regardless of treatment condition and mixing of the pre-treatment agent. Dry cleaning fastness of all samples are also 4-5 rating.

The dyeing with loess has been studied. Two kinds of cotton fabrics having different thickness and density were dyed in loess paste bath. The color differences of the fabrics which were dyed repeatedly.five times were not significant. The dyeing of cotton fabrics with loess was not exactly reproducible, but dyeability of the cotton fabrics of high density was better than that of low density. Loess on the dye6 fabrics was physically jammed between the fibers in the form of the fine particles. The cotton fabrics dyed with loess have good light fastness, but their laundering fastness and abrasion fastness were not good. An aftertreatment was carried out by using the extracted solution from acorn or persimon, and FeSO4 lot improving fastness. When the dyed fabrics was after-treated with FeSO4, the laundering fastness and wet abrasion fastness were improved extremely.
