摘要
文章分析了用Al3+对棉织物进行前媒过程中,媒染液中加入的碱对Al3+和棉织物之间的配合反应以及Al3+和OH-形成的沉淀反应的影响。几种不同结构的天然染料对媒染后棉织物进行染色后的试样表明,在媒染液中加入少量碱液,有利于Al3+与棉织物之间的配合反应,从而增加了天然染料在棉织物上的得色量。
Addition of small amount of alkali into mordant liquid facilitates the reaction between alumina and fabric so that the colour yield is enhanced when the cotton fabric after mordant treatment is dyed with natural dyes.However,in determining the addition amount of alkali,the reaction between alumina and fabric as well as the precipitate possibly formed with alumina should be taken into consideration.
