【摘要】:对有机溶剂碱催化蒸煮处理后的丝瓜络进行碱抽提、二氧化氯漂白和过氧化氢多段漂白。讨论了漂白过程中ClO_2和H_2O_2用量对漂白效果的影响。结果表明,当ClO_2用量为3%、H_2O_2用量为5%时,配合0.3%的MgSO_4和0.3%的Na_2SiO_3,在浴比为1∶9的条件下对样品进行漂白,得到的丝瓜络溶解浆浆粕的卡伯值达到较低水平,蒸煮后纤维表面附着物减少,木质素完全脱除。
[Abstract]:Alkali extraction, chlorine dioxide bleaching and hydrogen peroxide multistage bleaching were carried out on the luffa complex treated by alkali-catalyzed cooking with organic solvent. The effects of the dosage of ClO_2 and H_2O_2 on the bleaching effect were discussed. The results showed that when the dosage of ClO_2 was 3 / 10 / s / s, the samples were bleached with 0.3% MgSO_4 and 0.3% Na_2SiO_3, under the condition of 1:9 bath ratio. The kappa number of luffa complex dissolved pulp was lower than that of other pulp, the surface attachment was decreased and lignin was completely removed after cooking.
