Abstract

The objective of this work was to evaluate Turkey red oil as a renewable dispersant and leveling option for dyeing polyester knitted fabric with disperse dyes. The dyeing results were evaluated by measuring the color at several positions of the dyed samples to verify the levelness. In addition, the amount of residual dye was evaluated. Migration tests were also carried out to evaluate the leveling effectiveness of Turkey red oil. Wet rubbing and washing fastness analysis, hydrophilicity, thermogravimetric analysis (TGA), surface analysis with scanning electron microscopy (SEM) and modification of functional groups by FTIR were also carried out. The results obtained in the analyses show that Turkey red oil is efficient as a dispersant and leveling agent when compared to the well-known sodium naphthalene sulfonate. It is concluded that Turkey red oil reduces the time of the dyeing process and consequently its energy consumption, and reduces the amount of effluent generated while improving hydrophilicity and fastness, thus being a renewable and sustainable option for current products based on petroleum.

土耳其红油作为一种可再生的匀流剂和分散剂用于分散染料的聚酯染色

本研究的目的是评价土耳其红油作为分散染料染色涤纶针织物的可再生分散剂和整平剂的性能。通过在染色样品的几个位置测量颜色来评估染色结果，以验证染色的平整度。此外，还对染料残留量进行了评价。还进行了迁移试验，以评价土耳其红油的平整效果。湿摩擦和洗涤牢度分析、亲水性、热重分析(TGA)、表面扫描电镜分析(SEM)和FTIR官能团修饰。分析结果表明，与众所周知的萘磺酸钠相比，土耳其红油是一种有效的分散剂和流平剂。结论是，土耳其红油减少了染色过程的时间，从而减少了能耗，减少了废水的产生，同时改善了亲水性和牢度，因此是目前以石油为基础的产品的可再生和可持续选择。
