在本研究中，在次磷酸钠（SHP）存在和不存在的情况下，将具有不同羧酸基团数量的各种可生物降解有机酸掺入油墨配方中，以研究其显色率和抗菌性能。对经过预处理（工业标准做法）或未经预处理的棉织物上的喷墨印花进行分析，以确定其性能是否存在显着差异。并对印花棉织物的抗菌活性和固色性进行了测试。结果表明，在最佳pH条件下，未经预处理的油墨配方中含有更多的羧酸基团（BTCA），在没有SHP的情况下，印刷的样品比未经预处理的油墨配方中不含可生物降解有机酸的样品具有更高的活性染料固定和抗菌性能。采用ATR-FTIR和热重分析（TGA）对含BTCA无染料油墨配方的印花棉织物进行了表征，并通过扫描电镜（SEM）研究了其形貌，以确定是否发生交联。
In this study, various biodegradable organic acids with varying numbers of carboxylic acid groups were incorporated into the ink formulation both in the presence and absence of sodium hypophosphite (SHP) to investigate the colour yield and antibacterial properties. Ink-jet prints on cotton fabric, which were either pretreated (industry standard practice) or non-pre-treated, were analyzed to determine if there is a significant difference in their properties. Antibacterial activities and dye fixation of printed cotton fabrics were also tested. The results indicated that at optimum pH, the non-pretreated samples printed with ink formulations containing more carboxylic acid groups in their structure (BTCA) in the absence of SHP, demonstrated higher levels of reactive dye fixation and antibacterial properties than pre-treated samples containing no biodegradable organic acid in the ink formulation. The printed cotton fabrics with ink formulation that contained BTCA without dye were characterized by ATR-FTIR and thermogravimetric analysis (TGA) and their morphology was investigated through the use of SEM to determine if cross-linking had taken place.
