摘要
复配了一种新型去锰剂,通过测量牛仔布的K/S值来表征去锰效果,将新型去锰剂与传统去锰剂进行去锰效果对比,并探究了其对经过高锰酸钾处理的不同染料上染的牛仔面料的最佳去锰工艺。结果表明,由二氯化硫脲10%、过碳酸钠15%、氢氧化钠15%、元明粉60%复配而成的新型去锰剂,其用量仅为焦亚硫酸钠的近1/3即可达到传统去锰剂的使用效果,成本节约,生态环保。
A new demanganization agent is prepared and its demanganization effect is expressed by the measured K/S value of the jean. A comparison of demanganization effect by use of the new agent and traditional agent is made to explore the best demanganization process of the dyed jean treated by potassium permanganate. The result shows that a third of consumption of the new demanaganization agent of 10% thiourea dioxide, 15% sodium hydroxide, 15% sodium percarbonate and 60% sodium sulfate can meet the effect by use of traditional demanaganization agent, reduced the cost in a more environment protection.
