有机颜料蓝的纤维着色研究

An experiment on phthalocyanine blue dyeing fiber

有机颜料不溶于水,对纸浆着色较难。本文以酞菁蓝为例,尝试有机颜料在浆内纤维着色实验,比较了湿强剂、助留剂和明矾对颜料的着色程度和牢度,结果表明,三种化学品对颜料有固色作用,其中明矾的固色牢度最好。另外,本文还指出色密度指标较色差值检测的优点。

Organic pigment can’t be dissolved in water, so that it is difficult to color pulp. Phthalocyanine blue was tried in internal dyeing capability as an example. Wet strength agent, retention aid and alum were proved in its coloring and fastness, typically for alum. In this paper was also pointed out that using color density is prominent to using color difference in color paper tone test.
