摘　　要：采用四乙酰乙二胺(TAED)作为双蛋白混纺纱线双氧水漂白的活化剂,探讨了双氧水浓度、硅酸钠和碳酸钠用量、漂白温度和漂白时间对漂白纤维白度和黄度的影响。研究表明,在双氧水与TAED物质的量之比2∶1、30%双氧水10 g/L、碳酸钠3 g/L、硅酸钠3 g/L和70℃漂白60 min的条件下,漂白纤维白度高于常规双氧水漂白工艺,不仅避免了纤维的降解损伤,而且有利于节能减排。Low temperature hydrogen peroxide bleaching of double protein blend yarns with tetraacetylethylenediamine （TAED） as an activator is carried out. Influences of hydrogen peroxide concentration, dosages of sodium silicate and sodium carbonate, bleaching temperature and time on the whiteness and yellowness of the blended yarns are investigated. The results show that under the conditions of bleaching at 70 ℃ for 60 min with the mass ratio of hydrogen peroxide to TAED 2：1, 30% hydrogen peroxide 1.0 g/L, sodium silicate 3 g/L and sodium carbonate 3 g/L, the bleached blended yarn features higher whiteness, less damage to fibre and more energy saving than those of conventional hydrogen peroxide bleaching method.
