摘　　要：将温水沤制的胡麻纤维利用过氧化氢进行漂白处理,用测色配色仪、电子单线强力仪对漂白后的纤维进行表征,分析漂白时间、漂白液过氧化氢用量、硅酸钠用量、pH值、温度、浴比对胡麻白度、断裂强度及失重率的影响。结果表明:胡麻纤维的最佳漂白工艺为:过氧化氢质量浓度8 g/L,硅酸钠质量浓度7 g/L,漂白温度90℃,渗透剂JFC质量浓度2 g/L,pH值10,漂白时间70 min,浴比1∶40。在最佳工艺条件下对胡麻进行漂白并测试纤维性能。漂白后胡麻纤维的性能为:白度30.07%,断裂强度18.73 c N/dtex,纤维残胶率2.67%,纤维木质素含量1.72%。Using hydrogen peroxide method to warm water retting of flax fiber bleaching,and color matching instrument,electronic single strength tester were used to characterize the properties of bleached fiber,flax fiber bleaching after analysis. Using the single factor experiment by using only hydrogen peroxide bleaching of flax fibre,obtained the optimum bleaching of flax fibre is： H_2O_2 dosage of 8 g/L,dosage of sodium silicate is 7 g/L,bleaching temperature is 90 ℃,penetrant JFC dosage is 2 g/L,pH value is 10,bleaching time is 70 min,the bath ratio is 1∶ 40.
