To reduce the overdependence on petroleum-based surfactants for the dyeing of polyester fabrics, a series of biodegradable cardanol-based polyethoxylate oligomers (CPm, m = 5, 7 and 9) were synthesised by ethoxylation of cardanol with ethylene oxide. The synthesised compounds were characterised and confirmed by Fourier Transform–infrared spectroscopy and proton nuclear magnetic resonance spectroscopy. In addition, the physical, biodegradable and dyeing-assisting properties of CPm were evaluated through comparison with tristyrylphenol ethoxylates (A typical commercial surfactant). Results revealed that CPm showed a higher hydroxyl value, better dispersing capability and a higher migration percentage than tristyrylphenol ethoxylates. Specifically, CP5 (0.5 g/L) improved the migration percentage by 12.03% compared with tristyrylphenol ethoxylates. The migration performance of the surfactants followed a descending order of CP5 > CP7 > CP9 > tristyrylphenol ethoxylates. Importantly, CP5 displays a higher degradation propensity than tristyrylphenol ethoxylates, demonstrating its biodegradable merit. In summary, the cardanol-based polyethoxylates synthesised through this research are promising biodegradable and effective alternatives to conventional levelling agents for disperse dyeing, which contributes a new strategy to the sustainable development of the textile industry.

一种基于腰果酚的匀染剂的简便合成,作为三苯乙烯基苯酚乙氧基化物的可生物降解替代品,用于涤纶织物的染色

为了减少涤纶织物染色对石油基表面活性剂的过度依赖,通过用环氧乙烷对腰果酚进行乙氧基化,合成了一系列可生物降解的腰果酚基聚乙氧基化物低聚物(CPm,m = 5、7 和 9)。通过傅里叶变换红外光谱和质子核磁共振光谱对合成的化合物进行表征和确认。此外,通过与三苯乙烯基苯酚乙氧基化物(一种典型的商业表面活性剂)进行比较,评估了 CPm 的物理、生物降解和染色辅助性能。结果表明,与三苯乙烯基酚聚氧乙烯醚相比,CPm 具有更高的羟值、更好的分散能力和更高的迁移率。具体而言,与三苯乙烯基苯酚乙氧基化物相比,CP5 (0.5 g/L) 将迁移百分比提高了 12.03%。表面活性剂的迁移性能按照CP5 > CP7 > CP9 > 三苯乙烯基苯酚乙氧基化物的降序排列。重要的是,CP5 表现出比三苯乙烯基苯酚乙氧基化物更高的降解倾向,证明了其可生物降解的优点。综上所述,本研究合成的腰果酚基聚乙氧基化物是一种可生物降解的有效替代分散染色常规匀染剂的有效替代品,为纺织工业的可持续发展提供了新的战略。
