摘　　要：木屑作为木材加工的副产物,其产量在急剧增加。目前,人们基本采用酸性染料对木材进行染色,但着色的只是木质素部分,而占木材主要成分的纤维素和半纤维素并未上染。文章主要研究了前处理及活性染料染色拼色工艺对木屑日晒色牢度和水洗色牢度的影响,确定木屑色牢度较好时的染色工艺。结果表明:当染色温度为40℃、固色温度为60℃、染色时间为60 min时,经前处理后的木屑水洗和日晒色牢度较好。Wood sawdust,as a byproduct of wood processing,its yield is sharply increasing.Currently,people primarily use acid dyes for wood staining.However,only the lignin part is colored.The cellulose and hemicellulose,which are the main components of the wood,are not stained.This paper mainly studies the effects of pre-treatment and active dyes dyeing and color matching processes on the color fastness of wood sawdust to sunlight and washing,and determines the dyeing process when wood sawdust have good color fastness.The results showed that when the dyeing temperature was 40℃,the fixation temperature was 60℃,and the dyeing time was 60 minutes,the wood sawdusts after pre-treatment showed good color fastness to washing and sunlight.
