Glycol ether benzoates, glycol benzoates and methyl benzoate facilitate the dyeing of the meta-aramid article, e.g., fibers, at or near neutral pH. The addition of an anionic surfactant, such as sodium lauryl sulfate, enhances the performance of the benzoates.
乙二醇醚苯甲酸酯、乙二醇苯甲酸酯和苯甲酸甲酯有助于在中性或接近中性 pH 的条件下对偏芳纶产品(如纤维)进行染色。加入阴离子表面活性剂(如十二烷基硫酸钠)可提高苯甲酸酯的性能。
