Traditionally, wool fibers are dyed with acid dyes at the boil, which is energy-intensive process, and increases the cost of dyeing. The development of alternative energy-efficient dyeing processes is quite attractive to the textile industry to make textile dyeing sustainable. In this work, the feasibility of low-temperature dyeing of wool fabric with several aniline sulfonic acid (ASA) derivatives by oxidative polymerization method was investigated. The effect of dyebath conditions, such as monomer concentration, monomer to oxidant ratio, pH, temperature, and time on the shade produced and color strength was systematically studied. The treatment with various ASAs produced various yellowish-brown color shades with tonal change. The treatment conditions had a great effect on color strength and colorfastness to washing. The optimum treatment conditions were found to be pH 3, 30 °C, and 60 min. The excellent colorfastness to washing exhibited by the ASA-treated fabrics (colorfastness grades from 4 to 4–5) showed that the developed method could be used for the coloration of wool and other polyamide fibers.

传统上，羊毛纤维在煮沸时用酸性染料染色，这是高能耗的过程，并增加了染色成本。替代能源高效的染色工艺的发展对纺织业来说具有极大的吸引力，以使纺织品染色可持续发展。在这项工作中，研究了通过氧化聚合法用几种苯胺磺酸（ASA）衍生物对羊毛织物进行低温染色的可行性。系统地研究了染浴条件，如单体浓度，单体与氧化剂的比例，pH，温度和时间对产生的阴影和色强度的影响。各种ASA的处理产生了各种带色调变化的黄褐色色调。处理条件对色强度和耐洗色牢度有很大影响。发现最佳处理条件为pH 3、30°C和60分钟。ASA处理过的织物具有出色的耐洗色牢度（色牢度等级为4至4-5），表明该开发的方法可用于羊毛和其他聚酰胺纤维的着色。
