The metal complex dyes that are mainly used for good color fastness in dyeing amide fibers with highly concentrated colors usually contain toxic chromium. The remaining dye in th dyebath containing $Cr^{6+}$ causes not only environmental problems but also serious damages to human health. In this study, we applied reactive dyestuff for dyeing wool and nylon in order to substitute heavy metal dyestuff. The dyeing properties of reactive dyestuff in fibers as well as their absorption rates and fastness according to color concentration were investigated. By analyzing the quantity of heavy metals and toxic amine of reactive dyestuff, we investigated their harmfulness trends quantitatively. By comparing the reactive dyes with traditional metal complex dyes, we tried to find out the possibility of the reactive dye being a clean dyes in the future.

양모의 염색에서 특히 fiber dyeing, top dyeing, yarn dyeing이 양모 염색에서 큰 비중을 차지하고 있다. 그런데 이와 같이 섬유나 실 형태로 염색되는 경우에는 후속의 여러 습식 공정 중의 염색견뢰도가 매우 중요하기 때문에 $\alpha$-bromo acrylamide를 반응기로 갖는 반응성 염료의 사용량이 급격히 증가하고 있다. (중략)

단백질 섬유의 일종인 견섬유를 저온 플라즈마로 전처리한 후 효소처리하여 미처리시의 시료와 플라즈마처리 시료 및 효소처리한 시료에 대하여 역학특성, 염색성 및 태평가에 대해 비교, 고찰해 보았다. 인장강도, 인열강도 시험을 통해서 역학특성을 조사하였고, 산성 염료로 염색한 후 염색성의 변화를 알아보고, 염색견뢰도를 시험하였다. 플라즈마 전처리가 태평가에 미치는 영향을 알아보기 위해 Handle-O-Meter를 사용하여 태를 평가하였으며, SEM으로 시료의 표면을 관찰했다. 실험결과 플라즈마 전처리가 효소처리에 잇어서 섬유의 표면 특성 변화에 영향을 미친다고 생각된다.

Cationic dyeable polyester(CDP) was produced through melt blending of cationic chips having $2mol\%$ of sodium salt of dimethyl ester of 5-sulfoisophthalic acid(DMS salt) and normal polyester chips in different proportions to obtain yarns having varying amount of comonomer in the fiber. The modified polyesters showed increased moisture regain, decreased viscosity, lower softening point and improved antistatic characteristics, according to the amount of modifier. In dyeing at $100^{\circ}C$ the dyeing rate of cationic dyes with CDP fiber increased slowly than that of disperse dyes. In dyeing at $120^{\circ}C$ cationic dyes reached to equilibrium at 30min and disperse dyes at 10min. Cationic dyes in dyeing of CDP fabric have a better wash fastness compared with disperse dyes, also rubbing fastness of cationic dyes is better than that of disperse dyes. The light fastness of CDP fabric for cationic and disperse dyes is not good. The fastness of 75d/36f CDP fabric is higher than 75d/72f fabric. Solvent wicking fastness of CDP with cationic dyes is better than that of disperse dyes.

A natural dyeing makes fabrics look unique and elegant which cannot be obtain by synthetic dyestuffs. The natural dyestuffs are harmless to human, and it is easy to get them. Also, the natural dyestuffs are environmentally frendly, which is the anther merit for natural dyeing,We investigated dyeability with several fabrics (cotton, wool, ramie, silk and nylon) using an elm bark. We mordants(natural and synthetic). Also, colorfastness in dyed fabrics was estimated by laundering and light. The optimum condition of dyeability in elm bark was 60 min as time, $80^{\circ}C$ as temperature and 1: 40 as bath ratio. The dyeability in silk and nylon was the best among the sample. The treatment of mordants improved the dyeability and colorfastness in silk, wool and nylon. We obtain various color by the mordants.

The polyurethane prepolymers, which were previously synthesized from 2,4-toluene disocyanate(2,4-TDI) and polypropylene glycol(PPG), were chain extended by ethylene diamine or hydroxyl terminated polydimethylsiloxane(HTPMS) having hydroxy group at both ends of the chain, giving polyurethaneurea(PU) and polyurethane containing HTPMS segment(SiPU), respectively. In thermal gravimetric analysis, PU was almost completely degraded at $500^{circ}$ but SiPU showed about 11% residue at the same temperature. Suspension of SiPU and pigment showed more good compatibility than that of PU and pigment. The crocking fastness, migration fastness and solvent wicking were enhanced to 4.5 grades, 4 grades and 4 grades, respectively.

The natural dyeing of silk fabric with Scutellaria baicalensis extract was investigated. The proper colorant concentration, dyeing temperature, dyeing time, and pH for the dyeing of silk fabric with Scutellaria baicalensis extract were 90% v/v, $90^{\circ}C$, 60 minutes and pH 3, respectively. In various mordanted methods, the K/S values of mordanted methods were higher than those of unmordanted methods. Light colorfastness and washing colorfastness of Fe mordanted silk fabric was improved by mordanting. The antibacterial properties of dyed and mordanted silk fabric showed a high reduction rate, and Scutellaria baicalensis extract was showed effective bacterial reduction.
