聚丙烯酰氧基乙基三甲基氯化铵(PAOTAC)，其阳离子基团通过酯键与聚合物骨架连接，应用于棉的无盐活性染色，以获得良好的染色性能。在没有盐的情况下，对用 PAOTAC 阳离子化的棉进行浸染和浸染蒸汽染色程序；为了进行比较，两种染色程序也在盐存在下对未经处理的棉花进行了染色。染色结果表明，只有浸轧蒸汽染色工艺适合对阳离子棉进行染色，以达到较高的固色率。评估了不同染色方法的得色量、比色性能、牢度性能、染色匀染性和渗透行为。与传统浸染中未经处理的棉的染色相比，在浸染-蒸汽工艺中用阳离子棉进行的染色表现出相当甚至更好的牢度，并且通常具有更高的得色量和良好的染料渗透性。提出了无盐染色性能改善的可能原因，并通过红外光谱证明了在染色条件下PAOTAC内酯键的水解。 (C) 2011 年 Wiley 期刊公司 J Appl Polym Sci 122: 2741-2748, 2011
Poly(acryloxyethyl trimethylammonium chloride) (PAOTAC), in which cationic groups were connected with the polymer skeleton through ester bonds, was applied in the salt-free reactive dyeing of cotton with the aim of achieving good dyeing properties. Exhaust and exhaust-pad-steam dyeing procedures were used with the cotton cationized with PAOTAC in the absence of salt; for comparison, both dyeing procedures were also applied with the untreated cotton in the presence of salt. The dyeing results show that only the exhaust-pad-steam dyeing procedure was suitable for dyeing cationic cotton to achieve a high dye fixation. Color yields, colorimetric properties, fastness properties, dyeing levelness, and penetration behaviors with different dyeing methods were evaluated. Compared with the dyeings with untreated cotton in conventional exhaust dyeing, dyeings with cationic cotton in the exhaust-pad-steam procedure showed equivalent or even better fastness with generally higher color yields and good dye penetration. Possible reasons for the improved salt-free dyeing properties were proposed, and the hydrolysis of ester bonds within PAOTAC under the dyeing conditions was proven by IR spectroscopy.
