착색폐수의 정화와 탈색을 위한 화학침전/응집·부유법의 효율 및 비용

독일의 섬유가공장에서 발생하는 폐수는 주로 지방자치체의 정화장에서 처리되고 있다. 따라서 착색폐수가 유입되면, 그 색을 제거하는 것이 문제가 되고 있으며, 정수장의 출구에서 색이 잔류한 상태로 배출되게 된다. 일반폐수에 비해서 착색폐수의 비율이 비정상적으로 크게 되면, 정수장에서의 탈색은 불충분하게 된다. 그러므로 섬유가공장에서의 폐수평가와 정..

Focused on time and water efficiency

In the past year dyeing machine developments have been dominated by cycle time and water savings. The opportunities for saving time are in the preparation stage and rinsing processes rather than in the dyeing process itself. Details are given of the improvements made in the Gaston County AT, the Thies eco-Soft Plus, the Sclavos Venus, the..

Prevention of water pollution in dyeing processes of synthetic textiles

A brief description is given of a novel dyeing process for synthetic textiles. This process works completely without water, thus preventing or diminishing water pollution by dye houses. Using supercritical carbon dioxide as dyeing medium, several benefits like abandonment of any auxiliary chemicals (dispersants or surfactants) result in s..

환경을 고려한 합성염료 (제1부) 단백질섬유 및 폴리아미드섬유용 철착염

본 보에서는 1:2형 Fe착염아조염료를 합성해서 종래의 1:2형 Cr 및 Co착염염료와 비교하였다. 1:2형 염료를 질량분석한 결과, 1:1형 염료 및 착염하지 않은 염료도 검출되었다. 일광견뢰도와 마찰견뢰도면에서 보면, 1:2형 Fe착염염료 가운데 블랙염료가 양모 및 나일론에 대해서 일광견뢰도가 높은 염료이다. Fe착염의 색은 갈색, 황갈색, 검은색에 한정되지만, 염..
