In one bath dyeing system of silk/cellulose acetate fiber blend fabric with acid /disperse dyes, adsorption behavior of acid dyes and disperse dyes on silk and cellulose acetate fabrics were examined. In the dyeing of cellulose acetate with C. I. Disperse Red 19(Red 19) and C. I. Disperse Red 60(Red 60) at 8$0^{\circ}C$ and 10$0^{\circ}C$, dye uptake with Red 19 was higher than that with Red 60. When the silk/cellulose acetate dyed with Red 19 and Red 60 at 10$0^{\circ}C$, dye uptake on cellulose acetate was influenced by affinity of the dye to the silk fabric dyed together. When the silk/cellulose acetate dyed with Blue 80/Red 19 and Blue 80/Red 60 at 10$0^{\circ}C$, color of cellulose acetate dyed with Red 19 and Red 60 was not influenced by Blue 80 but silk dyed with Blue 80 was influenced by Red 19 and Red 60. Interrelation of K/S value and Munsell value was scarcely any but showed the change tendency of K/S value.

This study explores the kinds and types of dyes used in the Joseon Dynasty. Some literature including "Sanga Yorok", "Gyuhap Chongseo", "Imwon Gyeonjeji" were reviewed for this purpose. The findings are as follows. The colors obtained from the dyes were divided into seven color series, such as red, yellow and orange, green, blue, purple, brown, gray and black. These are practical color categories differed from abstract five cardinal colors [五方色]. The diachronic dyes used during the Joseon Dynasty were safflower and Japanese alder bark for red, indigo leaves for blue, gromwell for purple, chestnut tree bark for brown. The representative dyes used in the late Joseon Dynasty were safflower and sappan wood for red, wild pear tree bark and Pentapetes phoenicea for yellow and orange, indigo leaves for blue, sappan wood and gromwell for purple, mulberry tree for brown, and Chinese ink for gray. Common dyes used both in Joseon and China were safflower and sappan wood for red, pagoda tree blossom for yellow, a combination of pagoda tree blossom (or Amur cork tree) and indigo leaves (or sediment) for green, indigo leavers or sediment for blue, sappan wood and hollyhock for purple, and a combination of indigo leaves and Galla Rhois for gray and black.

In one bath dyeing system of silk/PET fiber blend fabric with acid/disperse dyes, adsorption behavior of disperse dyes and acid dyes on silk and PET fabrics were examined. In the dyeing of PET with C.I.Disperse Red 19(Red 19) and C.I.Disperse Red 60(Red 60) at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$, dye uptake with Red 60 was higher than that with Red 19. When the silk/PET dyed with Red 19 and Red 60 at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$, dye uptake on PET was influenced by affinity of the dye to the silk fabric dyed together. When the silk/PET dyed with Blue 80/Red 19 and Blue 80/Red 60 at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$ for 60 minutes, color of PET dyed with Red 19 and Red 60 was little influenced by Blue 80 but silk dyed with Blue 80 was influenced. Interrelation of K/S value and Munsell value was scarcely any but showed the change tendency of K/S value.

Two kinds of nylon 6 fabrics with different fiber denier, such as ultramicro fiber(UMF) nonwoven fabric(monodenier 0.05d) and regular fabric(monodenier 2.92d) are dyed with C.I. Acid Red 18(leveling type) and C.I. Acid Blue 113(milling type). Dyeing rates and adsorption isotherms are measured at $60^\circ{C}$, pH 5.0 and at liquor ratio of 1 : 250. To investigate the effect of fixing agents (Matexil FA-SNX, Monorex-RD and Tinofix-ECO) on UMF nylon 6 nonwoven fabric, dyeing is carried out at 3~10% owf with 1 : 2 metal-complex acid dyes, such as Kayalax Navy R(unsulphonated type), Lanasyn Blue S-BL(monosulphonated type) and Kayakalan Black BGL(disulphonated type). The dyeing rate of UMF nylon 6 is faster than that of regular nylon 6. From the results of absorption isotherms, the regular nylon 6 has higher saturation value of Acid Red 18 compared with UMF nylon 6, whereas UMF nylon 6 has higher saturation value of the acid Blue 113. From the absorption isotherms of both acid dyes, the regular nylon 6 has higher saturation value of Acid Red 18, whereas UMF nylon 6 has higher saturation value of the acid Blue 113. The wash fastnesses of UMF nylon 6 increases in the order of metal-complek dye containing nonsulphonated group > monosulphonated group>disulphonated group. Aftertreatment of UMF nylon 6 dyed with unsulponated and monosulphonated dyes improves wash fastness upto grade 1.5, where as that of UMF nylon 6 dyes with disulphonated dye does not improve wash fastness.

Dyes are released into the environment from industrial wasterwater. They are considered to be a pollution problem because of the wide spread into environment with a variety of colors. In order to biological treatment of industrial dyes waste water, biodegradation of reactive dyes such as Rifacion Red H-3EB, Rifazol Blue BT, Rifacion Yellow P-4G and Rifacion Brown RT were carried out decolorized by Aspergillus sojae B-10. Aspergillus sojae B-10 showed the almost completely biodegradation ability when it was cultivated in a 2.0% glucose, 0.06% sodium nitrite, 0.1% $KH_2PO_4$, 0.5% $MgSO_4\cdot 7H_2O$ containing each reactive dyes (500 ppm) under the optimal conditions of 32$\circ$C and pH 5. The mycelium of Aspergillus sojae B-10 was produced extracellular enzyme which has concerned responsible for dyes biodegradation. Under optimal conditions, reactive dyes started being decolorized within 24 hr and its was almost decolorized c ompletely after 5 days incubation. Rifazol blue RT was not completely decolorized until 5 days of cultivation. Rafacion Red BT, Rifasol blue BT and Rifacion yellow P-4G were completely decolorized after 5 days cultivation.

A mixed adsorbent prepared by pyrolysing a mixture of carbon and flyash in 1:1 ratio was tested for its deceleration ability for three different classes of dyes, namely Astrazone Blue FRR(C.I. Basic Blue 69), Teflon Blue ANL(C.I. Acid Slue 125) and Verofix Red(Reactive Red 3GL). Equilibrium investigations were carried out at the optimum conditions obtained in the previous studies. The equilibrium data fitted reasonably well to both the Freundlich and Langmuir adsorption models. However the Langmuir model was more appropriate to describe the adsorption behavior of the dyes to the hybrid absorbent system compared with the Freundlich model. The mixed adsorbent cm be an low-cost alternative to activated carbons.

The adsorption ability of dyes on chitin, a natural polymer was investigated for decolorization of dye wastewater. Chitin was manufactured in lab by decalcification in dilute aqueous HCI solution and deproteination in dilute aqueous NaOH solution with shrimp shells. Absorbance of residue solution of dyebaths after dye adsorptions of chitin were measured in varieties of dye concentration and dipping periods. Four kinds of dyestuffs were used, C.I.Acid Blue 29. C.I.Direct Blue 6, C.I.Reactive Orange 12 and C.I.Basic Red 18. When chtin 1g was dipped in 0.05% of dyebath with stirring, maximum adsorption ratio of each kind of dyes was exhibited as 91.6% for C.I.Acid Blue 29, 95% for C.I.Direct Blue 6, 58.2% for C.I.Reactive Orange 13 and 75.8% for C.I.Basic Red 19. It shows that chitin has better adsorption abilities of ionic dyes of acid, direct and basic dye than non-ionic reactive dye. And chitin has better adsorption abilities of anionic acid direct dyes than cationic basic dye because of the presence of nitrogen atoms. All kinds of dyestuffs used showed speedy absorption effects by chitin, so chitin can absorb much amount of dyes in 5 mimutes reach to equilibrium of adsorption in 2 hours after dipping. Basic dye was absorbed the most speedily in 5 minutes, although maximum adsorption ratio is not high. That reason can be thought that chitin surface is essentially negatively charged due to polar funtional groups.
