摘　　要：采用非离子表面活性剂PEG6000协同染料活性红SHF-GD对大麻纤维进行染色处理,以染色后大麻纤维吸尽率和固色率为指标,通过正交试验确定最佳染色工艺条件。试验结果为:在染色时间为80 min的前提下,添加染料及元明粉的温度为45℃,加入Na_2CO_3温度为65℃,元明粉质量浓度为55 g/L,无水碳酸钠质量浓度为25 g/L,非离子表面活性剂PEG6000的用量为0.1 g/g(干底物)。对染色后的大麻纤维进行扫描电镜表征,结果表明:染色后纤维的表面未遭到破坏,且染色后大麻纤维的匀染、透染性均较好,没有出现染色不均的现象。Non-ionic surfactant PEG6000 and reactive red SHF-GD was synergetic to dye hemp fiber,the dye absorption and fixation ratio was used to evaluate the dye effect through the orthogonal experiment,and the optimal dyeing process condition was determined as follows： on the premise of the dyeing time of 80 min,dye and Na2SO4 were added at temperature of 45 ℃,Na2CO3 was added when temperature is 65 ℃,Na2SO4 is 55 g/L,Na2CO3 is 25 g/L,PEG6000 is 0. 1 g/g（ dry substrate）. After dyeing,the hemp fiber were characterized by scanning electron microscopy. The results showed that the surface of the fiber was not damaged,and the levelness and penetration of dye on hemp fiber are good,the phenomenon of uneven dyeing was not appeared.
