摘　　要：竹浆纤维织物在染整加工中遇到湿、热、碱性条件时,强力有较大程度下降。研究了纯竹浆纤维织物在温和条件下的过氧乙酸漂白工艺及pH值、稳定剂对织物白度、顶破强力的影响,确定出最优工艺条件:过氧乙酸质量浓度5 g/L,pH值5,温度60℃,时间60 min,加入硫酸铵和尿素作稳定剂。结果表明,用过氧乙酸漂白可获得较高的白度且织物的损伤较小,其效果优于双氧水漂白。The wet, heat and alkaline conditions during dyeing and finishing bamboo fabric will cause a considerable loss of its strength. Bleaching of bamboo fabric with peracetic acid in mild condition and the effect of pH, stabilizer on the whiteness and bursting strength conditions were found： peracetic acid concentration 5 g/L addition of ammonium sulfate and urea as stabilizer. The of the fabric were studied. The optimum process , pH value 5, treating at 60 ℃ for 60 rain, with results show that higher whiteness values with less fabric damage are possible with peracetic acid bleaching process. Its effect is better than that of hydrogen peroxide bleaching.
