摘要
研究了以双氧水为主体漂白剂的丝瓜络漂白工艺。在漂白液中加入硅酸钠和硫酸镁;可以增大双氧水的漂白活性,提高丝瓜络的白度,经EDTA溶液浸泡过的作品不易返黄。在正交试验的基础上,优化了工艺参数,最佳工艺条件为:漂白液组成1%H2O2+5%Na2SiO3+0.1%MgSO4,氢离子浓度10pmol·L-1,漂白温度约60℃,漂白时间约1h。
The bleaching process of luffa pith was carried out by using hydrogen peroxide with bleaching assistants. Hydrogen peroxide solution with sodium metasilicate and magnesium sulfate had an enhanced effect on bleaching activity,whitening and softening luffa pith. Orthogonal experiment showed that optimum conditions were 1% (w/w) H2O2, 5% (W/W) Na2SiO3 and 0. 1% (w/w) MgSO4 at [H+] = 10 ×-11mol·L-1, 60℃ for 1 hour.
