摘要
保险粉与双氧水两浴两步法联合漂白黄麻纤维可显著地提高漂白效果,并且对纤维的损伤较小。保险粉和双氧水联合漂白是一种低污染、高效率漂白方法,其亨特白度值与亚氯酸钠漂白的相似,高达79.95。在漂白过程中,需严格控制保险粉和双氧水的质量浓度,最佳漂白质量浓度分别为6g/L和8g/L。
The whiteness of the jute fibres could be observed to be improved by the sodium dithionite bleaching and peroxide bleaching in two-step two-bath method,and the damage of the fibres was alleviated. The associated bleaching of sodium dithionite and peroxide is a good bleaching method with low pollution and high efficiency. During the bleaching process,the concentration of sodium dithionite and peroxide should be strictly controlled.
