Ramie는 통풍이 잘 되고 시원하며 가볍고 촉감이 깔깔하여 우리 나라에서 예로부터 여름 옷감으로 사용되어 왔다. 그러나 가격이 비싸고 열에 약한 단점이 있어 가격이 저렴하고 형태 안정성이 우수한 PET와 혼방된 제품으로써 많이 생산되고 있다. 혼방물의 염색 시 각 섬유는 본연의 특성에 맞는 염료를 사용하여 염색하게 되는데, 제품으로 사용하기 위해서는 염색 후 두 섬유의 색 강도를 같게 해줘야 한다. 그러므로 Ramie 섬유의 염색에 사용되는 반응성 염료와 PET 섬유의 염색 시 사용되는 분산염료가 같은 색강도를 가질 수있도록 각 염료의 농도를 찾아내는 것이 중요하다. 혼방물의 염색방법에는 각 섬유의 적합한 염색 조건에 맞는 2개의 염욕에서 순차적으로 염색하는 2욕 염색법과 하나의 염욕에서 각 섬유에 적합한 염색을 진행시키는 1욕 염색법이 있다. 2욕 염색법은 각 염료의 최적조건에서 염색하므로 염색성 및 견뢰도를 극대할 수 있다는 장점을 가지고 있는 반면, 소요시간이 길고 폐수의 양이 많다는 점을 고려할 때 향후 1욕 염색법이 경제적, 환경적 측면에서 효율적이라 할 수 있다. 본 연구에서는 Ramie/PET 혼방섬유의 1욕 염색법과 2욕 염색법을 이용한 염색성을 고찰을 통해 1욕 염색법의 적용 가능성을 고찰하였다.

The purposes of this work were suggested and validated the methods of heat recovery from dyeing wastewater exhausted in Sihwa and Banwol dyeing industrial park. We analyzed the present conditions of heat supplies and demands. So it was made a selection of the system combined heat exchanger for waste heat recovery and the high temperature heat pump. We decided the specifications of the heat recovery facilities. After this, economical assessment is performed to this system. The payback periods are within 4 years, 20 years and 5 years in case of K company, S company and A company. In addition, when they are produced the heat of same capacity, quantities of pollutants from used fuels were calculated.

Dyeing wastewater contains recalcitrant organics which can not be easily treated by conventional biological treatment. Therefore it has to be treated by other advanced oxidation process in order to remove COD and Color more efficiently. Fenton oxidation process is one of the most commonly applied processes in removal of COD and color for the dyeing wastewater. However it increase the treatment cost and the production of sludge by the use of the excessive chemical reagent. Ozonation is not suitable in Single treatment process because it is not effective in organics removal compared with Color removal. The purpose of this research in order to evaluate the comparable removal efficiency of COD and color by the combination of advanced oxidation processes for the dyeing wastewater. The sequential treatment processes of Fenton process and ozonation was more effective to remove organics and color than ozonation and Fenton process. The result of Fenton process for the pretreatment presented as the 81% removal of organics whereas ozonation process for the pretreatent presented as the 22.1% removal of organics. The removal of colour was higher as 81.3% for the ozonation as the pretreatment than 77.7% for the Fenton process as the pretreatment.

34 strains were isolated from dyeing wastewater in order to improve treatment efficiency of dyeing wastewater containing PVA. Two strains of them were finally selected through the PVA degrading test, and identified as Microbacterium barkeri LCa and Paenibacillus amylolyticus LCb. As a result, optimal conditions for microbial growth and PVA degradation were 30$^{\circ}C$, neutral pH, starch as a carbon source, and peptone as a nitrogen source. And it was concluded that these two strains have good ability for PVA degradation. And 90% over PVA was degraded by single culture as well as a mixed culture of 2 different strains.

The removal efficiency of organic compounds and the toxicity evaluation of microorganism have been studied in dye wastewater treatment using $UV/TiO_2$ and $UV/H_2O_2$ photooxidation system. Sample waters tested in this work were raw dye wastewater and dye wastewater treated in $UV/TiO_2$ and $UV/H_2O_2$ photooxidation system respectively. Total organic carbon(TOC) removal rate was 50% in $UV/TiO_2$ process and 80% in $UV/H_2O_2$ process. It has been investigated with colony counting agar method and paper disk method whether the type of treatment process has affected the microorganism growth. In the raw wastewater, more than four types of microorganisms have survived. But, little of microorganisms were alive at TOC removal rate of 50% in $UV/TiO_2$ system. In contrast to that, two types of microorganisms were found at TOC removal rate of 80% in $UV/H_2O_2$ system.

For the treatment of the dye wastewater, a polyamide nano-composite membrane and reverse osmosis (RO) membranes were prepared using interfacial polymerization technique, in which piperazine, meta-phenylene diamine, and trimesoyl chloride were used as monomers, Their permselective properties were characterized with aqueous solutions of PEG 600, $Na_2SO_4$, and NaCl, and their performance was compared with that of Osmonics Co, They were found to be a typical nano-composite membrane and a low pressure RO membrane. Using them, a real dye wastewater supplied from the Kyungin Corporation, one of the domestic dye producer, was treated, studying the separation performances of the membranes, Also, during the wastewater treatment, cleaning in place (CIP) of the membranes was carried out regularly to recover the flux of the membranes. Three different chemical cleaners were employed for the CIP process and their performance were compared in this study.

1956년 반응염료가 시판된 이래 장족의 발전을 하였으며, 구형의 cellulose용 염색을 추월하여 거의 대부분의 cellulose의 염색에 반응염료, 일변도로 사용되고 있는 것이 현실이다. 그러나 많은 반응 염료의 장점에도 불구하고 세월이 가면서 문제점도 만만치 않다. 장점으로는 색상이 선명하고 견뢰도가 우수하고 응용범위가 넓고 조작이 용이하다는 점이며, 문제점으로 나타난 것은 흡착염색공정에서 다량의 전해질과 알칼리제를 첨가함에도 불구하고 흡착율, 고착율이 낮고 염색후의 세정공정과 많은 물과 energy 및 시간을 필요로 한다는 사실이다. 또한 최근 더욱 관심을 끈 것은 반응염료의 가수분해 현상으로 인하여 다량의 가수분해된 염료가 폐수화하여 버려짐으써 심각한 공해가 야기할 뿐만 아니라 염색물에 부착하여 견뢰도에도 영향이 많다. 이런 문제를 염료제조업계에서는 해결하지 않으면 안될 시점에 와 있다. 이와 같은 문제점을 염료의 구조적인 면, 염색적인 면 그리고 소비자의 취급적인 면에서 검토하여 과거의 영광을 존속하기 위하여 개량형의 염료를 합성하여 고고착률, wash-off성의 양호 및 일광, 염소, 땀, 세탁 등에 견뢰한 염료를 얻고자 반응염료의 현황과 문제점을 정리해 보고자 한다.
