摘要
对比了过氧乙酸单漂、双氧水单漂、过氧乙酸与双氧水复漂及其次序组合对大麻织物的漂白效果,通过分析大麻织物的一些性能和木质素含量得出:过氧乙酸单漂(过氧乙酸10 g/L,60℃,pH=5.5)、双氧水单漂(双氧水10 g/L)、过氧乙酸初漂与双氧水复漂后大麻织物中木质素含量分别为4.02%、4.53%和3.63%.使用优选的过氧乙酸初漂与双氧水复漂结合进行,在保持一定强力前提下,可使大麻织物获得较好的白度.
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.
