Abstract
The bleaching effect of peracetic acid single bleaching,hydrogen peroxide single bleaching,the second bleaching and the order were compared.Through analyzing some performances of hemp fabric and content of lignin,it was concluded that the lignin content of hemp fabric using peracetic acid single bleaching with peracetic acid 10 g/L reacting at 60 ℃ under pH = 5.5,hydrogen peroxide single bleaching with hydrgen peroxide 10 g/L and peracetic acid first bleaching,hydrogen peroxide second bleaching was 4.02%,4.53% and 3.63%,respectively.peracetic acid first bleaching,hydrogen peroxide second bleaching could endow hemp fabric with good whiteness under certain strength.
