Abstract: 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 of the fabric were studied.The optimum process conditions were found: peracetic acid concentration(5 g/L),pH value 5, treating at 60 ℃ for 60 min,with addition of ammonium sulfate and urea as stabilizer.The 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.
