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.

조선시대 양반가의 장례시 매장방식은 회곽묘제를 사용하였으며, 그 유물들이 현대에 형태를 유지한 채로 출토되는 경우가 종종 있다. 그러나 그 내부에서 발견되는 섬유유물들은 예전에는 염직물이었을 것으로 예상되나 오랫동안 시즙과 수분에 의해 오염되어 고유의 색상 및 물성에 변화를 일으킬 수 있다. 이러한 오염은 출토 후에도 계속적으로 유물의 변퇴색 및 열화에 영향을 미칠 것으로 예상되므로 적합한 세척이 요구된다. 따라서 본 연구는 습식세척 후 출토염직물의 색변화를 최소화할 적합한 세정조건을 조사하기 위하여 적색계 7종, 청색계 1종, 황색계 6종, 녹색계 4종, 자색계 4종의 천연염색 염색포(견과 면)을 만들어서 이를 돈육과 함께 6개월간 냉장보관한 후 꺼내어 물, 음이온계면활성제(SDS), 비이온계면활성제(TritonX-100), 천연계면활성제(Saponin) 등 4종의 세정액를 이용하여 $20^{\circ}C$와 $40^{\circ}C$의 온도에서 습식세척하여 염직품들의 색상변화에 대한 영향을 조사하였다. 그 결과 색상의 변화는 세정온도, 섬유소재, 세정제, 이용한 염료의 종류에 따라 차이를 나타내었다.

Natural Artemisia extraction was extracted from Artemisia component using diethyl ether as a solvent, and we tested various pharmacetical and chemical characteristics of this extract. Characteristic experiments to use natural Artemisia extract tested antimicrobial experiment using microbe in pharmacetical material, and tested dye experiment using fiber in chemical material. From the result of characteristics experiment, some conclusions are obtained as follow. From the result of extraction experiment, it obtained about 10.4%-Artemisia extraction ratio as semi-solid state, and after dried in freezing from Artemisia extract of semi-solid state, it obtained about 10%-Artemisia extraction ratio as solid state of dark blue-green color. From result of antimicrobial experiment of Artemisia extract, number of staphylococcus aureus (ATCC-01) and aspergillus niger (ATCC-02) in microbe decreased more and more according to time passage. This phenomenon showed that Artemisia extract influences to antimicrobial effect. From the result of dye experiment of Artemisia extract, it appeared in direction of dark blue-green color after dyed to use cotton and silk with fiber to control in pH 7.5. Specially the result which confirmed dye of fiber with optical electron microscope (OEM), we could know that it appears darker silk than cotton.

This study discussed the dyeing of wool and cotton fabrics with Betel Palm Tree White woolen fabrics and cotton fabrics purchased from HATH (Korea Apparel Testing ＆ Research Institute) were used as experimental fabrics. Using dyeing powder extracted from dyeing material, various temperatures, dyeing times, and pH were used in the dyeing process. Al, Cr, Fe, Cu, and Sn were used as mordant and the absorption was compared with different mordanting methods. The optimum condition for pre-mordanting dyeing was dye concentration of 25% (o.w.f) and mordant concentration of 0.5$^{\circ}$∼1%. Woolen fabric showed an increase of absorption and the maximum absorption was achieved at weak acidity. According to the mordanting methods, woolen fabrics and cotton fabrics were treated with various mordanting agents, a mordant rate of 1:100, at 60$^{\circ}C$, for 30 minutes and dyed with a dyeing material concentration of 25% (o.w.f), at a rate of 1:100, at 60$^{\circ}C$ for 60 minutes. The best dyeing effect w3s achieved at the temperature of 60$^{\circ}C$ for cotton and 80$^{\circ}C$ for wool fabrics. The light fastness of cotton and wool fabrics was low and particularly the fastness to perspiration was decreased with Fe mordanting. I concluded that pre-mordanting method was better than post-mordanting method for cotton and woolen fabrics.

From result of antimicrobial experiment of grape extract, number of staphylococcus aureus (KCMC-01) and aspergillus niger (KCMC-02) in microbe decreased more and more according to time passage. This phenomenon showed that grape extract influences to antimicrobial effect. From the result of dye experiment of grape extract, it appeared in direction of dark purple color after dyed to use cotton and silk with fiber to control in pH 7.5. Specially the result which confirmed dye of fiber with optical electron microscope(OEM), we could know that it appears darker silk than cotton.

This study analyzes and compares Hanji made with loess to Hanji made with kaolin, two yellow-based inorganic pigments, in terms of its physical properties, optical properties, and color fastness to light with the aim of using it as a fashion material. Hanji made by adding inorganic pigments showed an approximately 20% retention ratio on average. This figure was similar to those of loess and kaolin. Physical properties were analyzed, with the following results. A higher amount of additives lowered the apparent density and increased thickness and bulk. In general, inorganic pigment-added Hanji had lower tensile strength, bursting strength, and folding endurance compared to non-additive Hanji. The analysis of optical properties showed a lower brightness index for Hanji made with inorganic pigments compared to non-additive Hanji. When comparing the two inorganic pigments, the brightness of Hanji made with kaolin was higher. Regarding color fastness to light, loess showed level 4 and kaolin showed level 5 when 25% inorganic pigments on pulp were added to Hanji. Thus, Hanji made by adding inorganic pigments during the manufacturing process may perform well as materials for fashion because the additives enhanced both the color fastness to light and the bulk while maintaining the strength. In addition, Hanji dyed with inorganic pigments may have the potential to serve as materials for the fashion industry while still retaining the characteristics of Hanji.

Two antibiotics, doxycycline (doxy) and ciprofloxacin (cipro) were applied under a variety of conditions to silk, and to silk that had previously been hydrolyzed. FTIR-ATR analyses indicated that the drastic increase in sorption of antibiotics by hydrolyzed silk was attributable to both chemical and conformational changes that occurred on hydrolysis. A high sorption of doxy by hydrolyzed silk did not necessarily give a more infection-resistant material as determined by a zone of inhibition test. Conversely, the same hydrolysis considerably increased both sorption of cipro and zone of inhibition of cipro-treated silk dyed at 65$^{\circ}C$ and 85$^{\circ}C$.

Polyester fabric is widely used in textile material though it has some problems such as low colour value, high refractive ratio(1.62) and etc. In order to give Z-black colour of polyester fabric, this study has selected several disperse dyes by measuring of absorbance, dyed in their optimum conditions and treated with 4 kinds of low refractive compounds such as silicone, fluorine, urethane and silicone-fluorine mixed compounds. The bathochromic effect of treated PET fabric evaluated as lightness(L) change by uv-visible spectrophotometer. This study also investigated that the effect of used bathochromic agents on the washing and lightfastness of treated PET fabric.

Microwaves are high frequency radiation capable of generating very rapid, uniform and efficient heating of textile material. Microwave heated dyeing of polyester fabric was tried with different solvent systems, irradiation time and dye concentration. Microwave fixation methods were used with 100% water,30% urea, EG and DMF, respectively, pad-baths in which the padded fabrics were exposed over a heated or boiling water bath to maintain sufficient moisture content during irradiation. In order to ascertain the relation between the dyeing property of polyester fabric and the microwave irradiation condition caused by microwave heating, the K/S values and fastness properties of dyed fabrics such as light, washing and sublimation fastness were measured.

In order to improve dyeability of poly(ethylene terephthalate)(PET) micro filament fabrics, the effect of the prior oxygen low temperature plasma on the subsequent dyeing(deep dyeing, printing) was examined in various conditions. The apparent concentration of dyed PET micro filament fabrics was increased by $O_{2}$plasma treatment. Higher discharge power levels and higher reactor pressure values created more significant effect. The wettability was significantly increased by $O_{2}$ plasma treatment. Therefore, it is predicted that introducing hydrophilic group on the surface of material can improve the apparent concentration of PET micro filament fabrics.
