摘要
选用8种染料对单叶省藤和黄藤进行染色,研究不同性质染料对藤材的影响,分析了不同结构染料对2种藤材渗透率的影响变化。结果表明:酸性大红-GR对单叶省藤和黄藤的纵向渗透率分别为48.2%和38.9%,与其他染料相比均是最大的,其染料上的—SO3H解离的磺酸基—SO-3与木纤维中的亲水基团通过氢键和范德华力形成共价键。不同结构染料对单叶省藤的渗透大小依次为酸性染料>活性染料>直接染料>碱性染料;对黄藤的渗透大小依次为活性染料>酸性染料>直接染料>碱性染料。
Calamus simplicifolius and Daemonorops margaritae are dyed with 8 kinds of dyes. Analyzsis of influence of different structure dyes on dye uptake with two kinds of rattan. The result shows that acid scarlet-GR is the biggest permeability of dye on C. simplicifolius and D. margaritae. The -SO3- of its -SO3 H and hydrophilic group of wood fiber compounded covalent bond with hydrogen bond and VDW. The influence of different structure of the dye penetration on C. simplicifolius has the order of acidic dye 〉 reactive dye 〉 direct dye 〉 alkaline dye;it＇s reactive dye 〉 acidic dye 〉 direct dye 〉 alkaline with D. margaritae.
