Biodegradable polybutylene succinate (PBS) fibre is a new type of textile fibre, but its application in the textile industry is limited by the lack of related dyeing methods. In this study, the solubility parameters of PBS fibres are calculated, and solvent dyes with similar solubility parameters are proposed to dye PBS fibres to show that the dyeing scheme creatively resolves the difficulty in dyeing PBS fibres. The technical parameters of suitable dyes, and the dyeing conditions with ethanol as the dyeing medium, consisted of a dyeing temperature of 90°C, a dyeing time of 30 minutes and a liquor ratio of 30:1. The dyeing results show that the levelling property is good, the dyebath exhaustion is high, and the washing fastness, the rubbing fastness and the perspiration fastness index of the dyed fibres are satisfactory.

聚丁二酸丁二酸酯纤维染色的系统研究

可生物降解的聚丁二酸丁二酯（PBS）纤维是一种新型的纺织纤维，但是由于缺乏相关的染色方法，其在纺织工业中的应用受到了限制。在这项研究中，计算了PBS纤维的溶解度参数，并提出了具有相似溶解度参数的溶剂染料对PBS纤维染色，以表明该染色方案创造性地解决了PBS纤维染色的难题。合适的染料的技术参数，以及以乙醇为染色介质的染色条件，由90℃的染色温度，30分钟的染色时间和30∶1的液比组成。染色结果表明，流平性好，染浴耗竭率高，染色纤维的水洗牢度，摩擦牢度和耐汗牢度指标令人满意。
