The purpose of this study is to enhance the usability of hanji fabrics by expanding the color space of hanji fabrics. For the expression of various colors of hanji fabrics, single and combination dyeing were carried out using natural indigo(Niram, Polygonum tinctorium), marigold extract colorant, and madder extract colorant for three types of hanji fabrics with different fiber compositions(hanji, hanji/cotton, hanji/silk). The light, medium, and deep colors obtained through individual single dyeing were shown to be PB Munsell colors in the case of indigo dyeing, Y color for marigold dyeing, and R color for madder dyeing. For combination dyeing, indigo dyeing was first carried out under the conditions for light, medium, and deep colors, respectively, and marigold or madder dyeing was performed thereafter. Indigo and marigold combination dyeing produced PB, B, BG, G, and GY Munsell colors and indigo and madder combination dyeing produced PB, P, RP, and R Munsell colors. Overall, the color change of hanji/silk fabric was more diverse than that of hanji fabric and hanji/cotton fabric. In the indigo, marigold, and madder combination dyeing into individual deep colors, blackish PB and P Munsell colors was obtained. Colorfastness to washing, dry cleaning, rubbing, and light were relatively good with above rating 4. Finally, 9 colors excluding YR color out of 10 Munsell color were obtained. We confirmed that the expansion of the color space of Hanji fabrics by the single and combination dyeing with indigo, marigold, and madder.

In this study, the properties such as color, dye uptake and antibacterial function were examined through the application of combination dyeing and mixed dyeing with extracts from Humulus japonicus(hwansam) and the pruned branches of Prunus persica(peach) tree. In terms of dye uptake and surface color changes subject to the kind of mordants, methods and mixing ratio of dye, it was found that fabrics dyed by the pre-mordanting method with $CuSO_4$ showed the red green yellow group colors, which were not seen in fabrics dyed with hwansam only. Color fastness was found strong at grade 4-5 with 96.3% of UV protection ratio. While the fastness to light was as fair as grade 3, it showed an excellent result of 99.9% bacteria reduction rate against Staphylococcus aureus with fair 58% deodorization rate and 21.2% antibacterial rate against Klebsiella pneumoniae. As stated above, the combination and mixed dyeing resulted in the meaningful outcomes with regard to color variations, dye uptake, color fastness and functional properties.

Dyeing of polyester/cotton blends is usually carried out through the two-bath or one-bath two-step dyeing method using proper disperse dyes and reactive dyes for each fiber. However, the dyeing requires relatively long and complicated procedure as well as there are some problems such as lower dyeability. In the present study, new one-bath one-step dyeing process was investigated using disperse dyes having amino groups and hetero-bifunctional bridge compound(DBDCBS) including dichloro-s-triazinyl groups and ${\alpha},{\beta}$-dibromopropionylamido groups to improve the dyeability of cotton component in polyester/cotton blends. And the one-bath dyeing properties of polyester/cotton blends was evaluated by various dyeing conditions such as pH, temperature and dye concentration, The optimum dyeing condition was pH 4 and $110-120^{\circ}C$. Color fastness were relatively good because of the colvalent bond formation between DBDCBS-reacted cotton fiber and disperse dye.

In order to dye nylon/cotton blended fabrics in solid colors with only acid dyes, a hetero-bifunctional bridge compound (DBDCBS) was examined. The bridge compound was designed to react only onto cotton fabrics first, on which amino-containing acid dyes react later by covalent bonding. By the effect of DBDCBS, amino-containing acid dyes exhibited high affinity toward the cotton fabrics. From the dyeing properties examined at various conditions, the optimum dyeing was decided at pH 4 and $100^{\circ}C$. Consequently, the solid color was obtained on nylon/cotton blended fabrics in one bath dyeing process using only acid dyes. The DBDCBS did not show any negative effect on nylon side in terms of dyeing and physical properties.

Dyeing fabric weaved with two or more kinds of fiber in different section has various dyeing interactions caused by different material properties of them. Newly developed knit fabric was used in this study. It composited by two different blocks, each block is included PET fiber and CDP fiber separately. Build-up properties with cation dyes and disperse dyes were good having average 83% of dyeing exhaustion yield on 5% o.w.f. dye concentration. As depending on dyeing methods, there were not showed direct interaction between cation dyes and disperse dyes. This result could be considered their different dyeing mechanism. Compatibility was best in S-type disperse dyes investigated their critical absorption range as $120^{\circ}C{\sim}130^{\circ}C$. Wash fastness was generally good in most dye.

Jacquard floor covering could be prepared from low-melting/regular sheath-core hybrid polyester, where the fiber is dyed in yarn state. With regard that the expected high shrinkage of the hybrid polyester in water makes problems in yarn dyeing, low-temperature dyeing properties of the hybrid polyester were studied. The rate of shrinkage of low-melting hybrid polyester exceeds 9% in hot water above $90^{\circ}C$, at such condition, cheese yarn dyeing is very difficult. Although disperse dyes exhaust in a relatively high speed on low-melting hybrid polyester, diffusion of these dyes to the core regular polyester was extremely slow under $90^{\circ}C$. Foron Blue E-BL 150, an anthraquinone E-type disperse dye, showed appreciable diffusion after 48hrs dyeing at $90^{\circ}C$. The fastness to rubbing and drycleaning were improved by one grade after reduction cleaning.

In this study, as one of the eco-friendly dyeing methods, indigo, Phellodendron amurense and Caeasapinia sappan were complexed dyed on cotton fabric. For complexed dyeing, the cotton that was pre-dyed 5 times with indigo was dyed 1 ~ 2 times repeatedly with Phellodendron amurense and Caeasapinia sappan. Then the color, tensile strength, density, and color fastness of complexed dyed sample were analyzed and the following analysis results could be obtained. As a result of color difference measurement, the L* value was 22.7 in the sample in which the cotton was dyed 5 times and then the Phellodendron amurense was dyed 1 time, and the K/S value was 15 or higher in all samples. As a result of measuring the strength, cotton fabrics tended to have a slight decrease in tensile strength when complexed dyeing. As a result of measuring the density, the density decreased by 15 ~ 20% in all samples at the warp and increased by 20 ~ 30% in the weft due to the complexed dyeing of cotton fabric. Moreover, the fastness to washing and drycleaning showed good results of 2 ~ 3 or higher, and the light fastness was 4 or higher.

Dyestuffs extracted from fifteen kinds of natural dyeing materials were researched on their antimicrobial performance against 3 kinds of bacteria and 2 kinds of fungi in order to develop conservation/storage materials of traditional and natural dyed papers. The three types of mordants were evaluated by using the same method and then mixed with the dyestuffs to research their antimicrobial performance. With those results, dyed paper was made by mixing mordants with 9 kinds of dyestuffs with excellent antimicrobial performance. Among the dyed papers, Cotinus coggygria, Coptis chinensis, Phellodendri amurense, Rhus javanica and Acer ginnala multiple mordant papers were found to have an antibacterial quality against fungi, while, in the insect repellent experiment using termites, Coptis chinensis and Phellodendri amurense dyed papers were found to have insect repellent qualities. Also, with regard to the research result about the affect of dyeing paper on other materials like metal, Coptis chinensis have relatively stable qualities. Also, the three types of dyeed paper by Cotinus coggygria, Coptis chinensis and Phellodendri amurense, were found to have a tendency to remove harmful gases. Not only can these dyed papers be used for making storage box for cultural properties to prevent various organic artifacts from bio-damaging, but they can also be utilized as functional finishing materials in various spaces.
