  • 본 연구의 목적은 트리아세테이트와 흡한속건성 PET 합연사로 구성된 복합직물의 염착량 증진 및 동일색상 염색(union dyeing)을 위한 최적 혼합염색 조건을 찾는 것이다. 이를 위하여 E-type 분산염료(C.I. Disperse red 50)와 S-type 분산염료(C.I. Disperse red 92)를 혼합하여 1욕 혼합염색으로 염색온도, 염색시간, 염료의 혼합비율에 따른 염색직물의 흡진율, 염착율, 색상 및 색차를 측정하였다. 혼합염색의 염착평형은 $100^{\circ}C$에서 일어났으나 염색된 직물의 K/S 값과 겉보기 색상을 비교해보았을 때 트리아세테이트와 흡한속건성 PET의 색이 동일한 색으로 발현되는 온도는 $120^{\circ}C$임을 확인하였다. 염색 시간 증가에 따른 혼합염료 흡진율과 염착량의 변화는 크게 나타나지 않았으나 염색시간이 길수록 그리고 혼합염료를 사용할 경우 균일한 색상을 얻을 수 있었다. E-type에 S-type염료의 혼합비율을 적절히 조절하여 혼합염색 하면 단독염색 보다 E-type 염료의 색상과 차이 없이 염착량을 증대시킬 수 있었다.

  • PET fabric was dyed in black shade with disperse dyes of three primary color. The effect of combination ratio of dye concentration and energy type of disperse dye on dyeing and color property of black dyed PET fabric was investigated. Dyeing compatibility of disperse dyes of three primary color on PET was evaluated by comparison of dyeing rates of them. From the results, color property was dependent upon the combination ratio of dye concentration. In order to obtain low lightness ($L^*$) and black color, blue dye should be added enough. S-type disperse dye and $130^{\circ}C$ dyeing was suitable rather than SE-type dyes or $120^{\circ}C$ dyeing. Disperse dyes of three primary color used showed good dyeing compatibility at high dye concentration. Washfastness was fair to moderate and lightfastness was moderate.

  • The antibiotic reactive dye was synthesized by coupling of reactive chromagen with diazotised silver sulfadiazine for an antibiotic property. The highly reactive MCT(monochlorotriazine) and DCT (dichlorotriazine) type functional groups which have heterocyclic ring and moderately reactive VS-type dye that has good dyeability were used for reactivity. The synthesized antibiotic reactive dye is expected to impart the antibiotic function with high durability on cotton fabric only by one-step dyeing process without further finishing treatment. The synthesis of antibiotic dye was easily proceeded thorough diazotisation of silver sulfadiazine and coupling with suitable chromogen. The dyeability of synthesized dye for cotton fabrics was excellent and the dyed fabrics showed good level of lightfastness, resistance to washing and rubbing. The antibiotic tests revealed that the dyed cotton fabrics with the synthesized dye had very good antibiotic properties.

  • In this study, the dyeability of 0.06-denier-per-filament (dpf) ultrafine sea-island-type nylon knitted fabric was investigated and compared with that of 1.0-dpf general nylon with respect to four types of dyes. In particular, leveling, milling, half-milling, and metal-complex dyes were compared at concentrations of 0.5%, 1.0%, 2.0%, 4.0%, and 8.0% on-weight-fabric (o.w.f). In each case, staining was performed at 100 ℃. The dyeabilities of the materials were compared in terms of the depth of color as defined by the ratio of the absorption coefficient (K) to the scattering coefficient (S). Results indicated generally low K/S values for both the 0.06-dpf ultrafine sea-island-type nylon and 1.0-dpf general nylon. In terms of the dye type, the milling and half-milling dyes exhibited K/S values of ≥20 for all colors of yellow, red, and blue for the 0.06-dpf ultrafine yarn sea-island-type nylon, which were superior to those of the other dye types. Hence, the milling and half-milling dyes are considered more suitable than the other dyes. Further, a comparison of dye fastness and compatibility revealed that the half-milling dye was the most suitable dye for the 0.06-dpf ultrafine sea-island-type nylon.

  • This study intends to find out possible variations in physical properties and color of hair depending on dye type(acidic and alkalic) and permanent treatment/hair dyeing procedure. To meet the goals, healthy hair samples were taken from 5 women's hair speciment in 20's without experiencing in any harmful substance via long-term medications. and beauty care using chemicals. To get possible findings depending upon hair dye type and treatment procedure, both acidic and alkalic hair dye were applied on some specimens after permanent treatment, while on other specimens before permanent treatment. In order to determine scale damage, this study used SEM(Hitachi S-2500C) both hair thickness and tensile strength were measured with optical microscope(Nikon, MM-60/L3T) and Instron (4482-standard). Wave configuration was measured transverse and longitudinal round diameter. The chromaticity of each specimen was measured using a spectrocolorimeter(Color Techno System, JP/JX-777) with visual $C/2^{\circ}$ (at $2^{\circ}$ with C light source) monitor fixed to determine Lab and CMYK values. As a result, it was found that hair specimens were more significantly damaged with alkalic hair dye treatment than with acidic hair dye treatment, while hair specimens were more effectively dyed with the former hair dye type than with the latter one. For possible results depending on treatment procedure, it was found that hair specimens were less damaged but more effectively dyed with permanent treatment followed by hair dyeing than vice versa. Therefore, it was concluded that permanent treatment followed by acidic hair dyeing would be more effective in reducing hair damages.

  • Nanostructured metal oxides have been widely used in the research fields of photoelectrochemistry, photochemistry and opto-electronics. Dye-sensitized solar cell is a typical example because it is based on nanostructured $TiO_2$. Since the discovery of dye-sensitized solar cell in 1991, it has been considered as a promising photovoltaic solar cell because of low-cost, colorful and semitransparent characteristics. Unlike p-n junction type solar cell, dye-sensitized solar cell is photoelectrochemical type and is usually composed of the dye-adsorbed nanocrystalline metal oxide, the iodide/tri-iodide redox electrolyte and the Pt and/or carbon counter electrode. Among the studied issues to improve efficiency of dye-sensitized solar cell, nanoengineering technologies of metal oxide particle and film have been reviewed in terms of improving optical property, electron transport and electron life time.

  • The effect of organic solvent in the dyeing of silk fiber by acid dye was investigated. Acetophenone and benzyl alcohol were shown to be the most effective for the rate of dyeing of silk fiber by Milling Cyanine 5R (C.I. Acid Blue 113), a milling type acid dye, but, with benzyl alcohol, the equilibrium dye uptake was much lower than that in the absence of it. In the presence of solvent, maximum dye uptake shifted to lower temperature than 6$0^{\circ}C$, while without solvent, it was shown at about $60^\circ{C}$. When dyed by Orange II (C.I. acid Orange 7) under same condition equilibrium dye uptake of silk fiber was lower than that for milling type acid dye, and in the presence of benzyl alcohol, still much lower uptake resulted. All these fact reveals that organic solvents in the solvent-assisted dyeing of silk fiber broaden micelle spacings too much, resulting in increased rate of dyeing, and decreased equilibrium dye uptake, contrary to wool.

  • The alkaline dissolution behavior of sea-island type polyarnide microfibers were successfully monitored using a cationic dye staining method. Weight reduction behavior of the alkali-treated microfiber fabrics and the treated fabrics stained with cationic dye were investigated in a comparative manner. The termination of dissolution monitored by both methods was also confirmed by scanning electron microscopy.

  • We have demonstrated Forst-type resonance energy transfer (FRET) in the quasi-solid type dye-sensitized solar cells between organic fluorescence materials as an energy donor doped in polymeric gel electrolyte and ruthenium complex as an energy acceptor on surface of $TiO_2$. The strong spectral overlap of emission/absorption of energy donor and acceptor is required to get high FRET efficiency. The judicious choice of energy donor allows the enhancement of light harvesting characters of energy acceptor in quasi-solid dye sensitized solar cells which increase the power conversion efficiency. The enhanced light harvesting effect by the judicious choice/design of the fluorescence materials and sensitizing dyes permits the enhancement of photovoltaic performance of DSSC.
