高锰酸钾漂白工艺研究及效果评价

Potassium Permanganate Bleaching

利用高锰酸钾在酸性介质中的氧化性能 ,对煮练后的棉织物分别采用浸漂和轧漂两种方式进行漂白 ,分析高锰酸钾漂白液的稳定性和影响漂白工艺的关键因素 ;并对漂白效果、漂白成本等与车间常规双氧水漂白工艺进行对比 ,分析采用高锰酸钾漂白工艺的可能性。

Taking advantages of oxidizability of potassium permanganate (KMnO 4) in acid media, the scoured cotton fabric was bleached with potassium permanganate (KMnO 4) using dipping and padding processes respectively. The stability of potassium permanganate (KMnO 4) and the factors affecting the bleaching process were analysed. The results and cost of bleaching were compared to those of traditional H 2O 2 bleaching.
