우리나라의 섬유산업 중 염색가공 분야는 에너지 다소비 업종으로, 노동 집약적 특성에 따라 원단위 생산성이 낮고, 대부분 중소·영세기업 특징이 있다. 염색 원단의 불량률이 높아지면 재염색으로 인한 생산단가 상승과 초과 에너지 투입으로 비용이 증가하기 때문에, 불량률을 최소를 통한 생산량 향상이 초점이었다. 또한 고온고압의 환경에서 이루어지는 염색공정은 사고 위험으로 염색기 원단 투입구를 실시간으로 개방할 수 없기 때문에 실시간으로 원단의 염색상태 확인이 어려웠다. 최근에는 염액을 실시간으로 모니터링하는 연구가 활발히 진행중이다. 본 논문에서는 탁도, pH, 전도도 센서를 이용하여 염액의 흡진율을 계측할 수 있는 복합센서 흡진율 모델 및 구성시스템을 제안하였으며, 실험방법소개와 실험결과 분석을 실시하였다.

Reuse of wastewater become an important consideration to solve the environmental pollution problems in recent industriallzation and urbanization. Especially, he characteristic of dyeing process is subject to use much water and thus has serious problems for removal of color and organic pollutants in their wastewater. This report is divided into two main parts ： The purpose of the first part was to determine if alkaline wastewater discharged from textile dyeing operation factory could be flocculated directly by Fenton oxidation method. This study was conducted to investigate Fenton reagent dose and reaction condition of Fenton method as pretreatment for dyeing wastewater in K dyeing industry were investigated. In the second part of this research, to treat dyeing wastewater it was found that the most effective way is to use ultrafiltation and reverse osmosis at the conditions of the pH 7.0~8.0 and operating pressure of $2.5~35kg_f/cm^2$. This paper is mainly dealt with the application on reuse system of dyeing wastewater treatment using ultrafiltration and reverse osmosis membranes. The results showed that dyeing wastewater could be reused by chemical, filter and membrane sequential treatment process.

The study has focused on the dyeing properties of 4 kinds of high temperature type mono azo disperse dyes, widely used in the dyeing factory, under the ultra low liqour ratio (1:4) dyeing condition. Among those, C.I. Disperse Red 343 and C.I. Disperse Blue 79 showed un-levelled dyeing results from the ultra low liquor ratio dyeing bath as well as poor dispersion stability under the high temperature. We recommended some leveling agents to improve the leveling behavior of these dyes mentioned above. The milling technology should be further developed to achieve the dispersion stability.

슬러지를 매립하는 경우 빗물의 유입이나 주변 지하수의 수분을 흡수하여 지반이 전체적으로 연약해 지는 경우가 발생한다. 본 연구에서는 탈수한 염색슬러지를 매립한 경우의 문제점을 확인하기 위해 염색슬러지와 염색슬러지-토사 혼합샘플에 대한 시험을 수행하였다. 염색슬러지가 배수가 원활하지 못한 매립지 내부에서 함수비가 높은 상태로 장기간 방치되면, 염색공장의 염색슬러지와 비교하여 투수성이 약 3/100 수준으로 낮아지고 압축성이 1.4배 증가하는 것으로 나타났다. 매립지의 안정성 확보를 위해 매립지 내부 함수비를 저하시키는 것이 중요하며, 배수로의 확보와 침출수 배제시설을 통한 관리가 필요할 것으로 판단된다.

본 연구는 청정생산기술의 개념을 염색가공분야에 도입시키기 위한 방법론을 제시한 것이다. 먼저 각 분야별 전문가로 이루어진 진단지도팀을 구성하여 대상업체에서 진행중인 제조공정 진행상태를 파악하고 사용하는 원부자재의 성능 및 환경적 분석과 폐수의 환경적 분석을 실시하였다. 원부자재(조제 및 염료)의 환경성은 TOC, CODMn, CODCr, $BOD_5$의 항목으로 평가하였고, 발생되는 폐수는 TOC, CODMn, CODCr, $BOD_5$, TDS, pH의 항목으로 평가하였다. 또 물질수지 분석과 LCA 평가 후 다음 단계로 공정, 에너지, 원부자재, 생산관리, 일반관리에서의 문제점을 도출한 후 그 중에서 개선 대상을 선정하고 마지막 단계에서 각 부분에 대해 지도하여 개선토록 한 후 최종 개선 효과를 분석하였다.

Acid erosion of teeth was studied in two factories. The A was the textile factory possessing dyeing process using acids. The B was the metal product manufactoring factory possessing electroplating process. The control group was selected at the same factory not exposed to acids. The results were summarized as below. 1. The pH of saliva was the range of $6.6{\sim}6.8$ in both factories. 2. The prevalence rate of erosion of teeth was higher in case group at the B. It was statistically significant. 3. The rate of erosion of incisor were the range of $12%{\sim}16%$(case group), $7%{\sim}21%$(control group) at the A and $10%{\sim}20%$ (case group), $2%{\sim}15%$ (control group) at the B. 4. The rate of erosion of degree 3 which is necessary for conforming, owing to occupational induction, were 8.9% (incisor: A) and 6.8% (incisor: B).

Simulation techniques are used to improve the productivity of a textile factory. A simulation model is developed for the analysis of investment for dyeing process equipment, such as dryers and bleachers. For modeling and analysis, AIM (Analyzer for Improving Manufacturing) is used. AIM is a manufacturing oriented simulation software developed by Pritsker Corp. AIM provides interactive model building and simulation, automatic animation, and powerful graphic outputs. thereby, drastically reducing modeling efforts and also enhancing communication capabilities.

염색가공공정은 에너지 다소비형이며, 염색조업을 수행하는 과정에서 약 4$0^{\circ}C$ 정도의 열원폐수를 다량으로 방출하고 있지만 이를 회수할 수 있는 기술개발이 이루어지지 않아서 아직 미활용되고 있다. 본 연구에서는 이와 같은 열원폐수의 열을 회수하여 이용할 수 있는 방안을 마련하기 위하여 먼저 염색공정의 특성을 고찰하고. 직물별, 공정별 에너지원단위를 조사한 결과 상대적으로 에너지원같위가 높은 T/C, T/R 교직물 업체나 폴리에스테르 염색업체에서 폐수열을 회수하여 이용하기에 적합한 것을 알 수 있다. 그리고 염색업체별, 계절별 폐수의 배출량과 온도를 조사한 결과 각 업체당 평균 폐수배출량은 20,470톤/월이고, 평균폐수온도는 41.$0^{\circ}C$로 나타났다 또한, 배관 침적, 폐쇄 등으로 폐열회수시스템의 안정적 운전이나 열교환기의 성능에 악영향을 끼칠 수 있는 SS의 경우 폴리에스테르 염색폐수가 가장 낮아 폴리에스테르 염색폐수가 폐열회수에 가장 유리할 것으로 판단되었다. 염색공장에서 기존에 사용하고 있는 시스템과 폐수열이용 시스템의 에너지단가를 비교해보면 폐열회수시스템에서 압축식 열펌프를 적용하면 에너지단가는 22.50원이 되어 매우 경제적이며, 증기생산을 위한 보일러 연료로 LNG를 사용하는 업체에 압축식 폐열회수시스템을 적용할 경우가 투자비 회수기간이 2.09년으로 경제성이 매우 우수한 것으로 나타나 열펌프시스템의 적용기술을 보급할 수 있는 기반을 마련하였다.

Recently, Industry 4.0 (next generation industrial revolution) designed by Germany to retain initiative in manufacturing business is actively studied. Goal of Industry 4.0 is 'Smart factory' which manages progress of production, supply logistics and services. To achieve the goal, we can construct value creation and new business model by integrating organically with production management systems which is existing and cyber-physical systems, Internet of Things, Services Internet and sensor, etc. However, if integration with production management systems does not work effectively by adding and developing new technologies, It does not have performance. Hence, in this research, we will analysis Industry 4.0 which is possible for small quantity batch production and one of the light and flexible manufacturing systems, and based on this, we will suggest methodology to horizontally integrate with production management systems.

Fur clothing as fashion items is expanding into casual & ladies's wear market as well as fur market. The interest of fur fashion is rising. So this study compares and analyzes the merchandising process of textile clothing also it of fur clothing by merchandising steps. Fur clothing has so many change factors at time of purchase by scarcity of raw material, price fluctuation, exchange rate and others. Therefore it is primarily about securing of raw material. As soon as plan of product is finished, the purchase of fur raw material has to be started while progress of design products for commercializing the fur clothing. The design of fur clothing is consist of material design, color design and shape design. And It makes a new trend & market as we are developing new & various treatments. The some of imported materials are transferred to the factory for being treated first dressing, fabric treatments and dyeing processing according to the design. The first treated materials are transferred to the sewing factory again for secondary treatments and finally inspected and shipped. During secondary treatments the fur has gone through various manufacturing process for using like fabric materials and it takes long time because almost work is running manually. Unlike fabric clothing, fur clothing's manufacturing method is complicated and various from material process to shape process as per feature. Therefore the merchandising with fur cannot make mass production also needs detail craftsmanship depending by expert's skills. On this wise the fur clothing takes long time to the completion thus it has been risky and costly.
