Fluorescent brightening agent OB-1 (OB-1) is often used in plastic goods because of its non-toxic nature, chemical stability, remarkable heat resistance, and light stability. Raw OB-1 is challenging to use in textiles using the exhaustion method. This study used a novel method using raw OB-1 powder to whiten polyester fabric in water and decamethylcyclopentasiloxane (D5). The Taguchi approach investigated the interaction between whitening process parameters such as temperature, OB-1 mass, water: D5 ratio, and treatment time with four levels. The study shows that the temperature and water: D5 ratio during the whitening process significantly affect the whiteness of polyester fabric (P < 0.05), with contribution percentages of 74.2 % and 25.2 %. Subsequently, various analytical techniques were employed, including FTIR, SEM, TGA, and XRD, to characterise the whitened fabric. The findings imply that using water: D5 medium was effective in whitening polyester fabric without causing major alterations to the structure of the PET fabric. The study also examined the fastness of washing and crocking to determine their whitening stability. Overall, polyester fabric whitened with water and D5 medium exhibited satisfactory whitening performance and might be a potential scope for use on a larger scale in developing the sustainable textile industry.
荧光增白剂OB-1（OB-1）因其无毒、化学稳定性好、耐热性和耐光性强，常用于塑料制品。采用竭染法将未处理的OB-1用于纺织品具有挑战性。本研究采用一种新方法，使用未处理的OB-1粉末在水和十甲基环五硅氧烷（D5）中对聚酯织物进行增白。田口方法研究了温度、OB-1质量、水与D5的比例以及处理时间等增白工艺参数在四个水平下的相互作用。研究表明，增白过程中的温度和水与D5的比例对聚酯织物白度有显著影响（P < 0.05），贡献率分别为74.2%和25.2%。随后，采用了包括傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）、热重分析（TGA）和X射线衍射（XRD）等多种分析技术对增白后的织物进行表征。研究结果表明，用水与D5的混合介质对聚酯织物进行增白是有效的，且不会对聚酯织物的结构造成重大改变。该研究还检测了洗涤和摩擦牢度，以确定其增白稳定性。总体而言，用水和D5介质增白的聚酯织物具有令人满意的增白性能，在可持续纺织工业发展中可能具有更大规模应用的潜力。
