Maleic acid (MA) has been explored to replace formaldehyde-based dimethylol dihydroxy ethylene urea (DMDHEU) for cotton anti-crease finishing. However, the resilience of treated fabrics was not satisfactorily improved. In this study, acryloyl malic acid (AMA) was synthesized and applied on fabrics as a novel crosslinking agent. The results showed that both crease recovery angle and whiteness index of treated samples were higher than those of MA in the presence/absence of catalyst sodium hypophosphite (SHP). Chemical structure of AMA was confirmed by NMR and MS spectra. The possible crosslinking mechanism between AMA and cellulose was investigated by means of (13)C NMR, MS, FTIR and phosphorus content analyses. It was found that AMA could form ester bonds with cellulose by formation of anhydride intermediate. Meanwhile, additional reaction of double bonds on AMA with another molecule or PH of SHP residual has also contributed to the crosslinking. A reaction equation was proposed based on the analyses.
马来酸（MA）已被探索用于替代基于甲醛的二羟甲基二羟乙烯脲（DMDHEU）进行棉织物防皱整理。然而，处理后的织物的弹性并没有得到令人满意的改善。在这项研究中，合成了丙烯酰基马来酸（AMA），并将其作为一种新型交联剂应用于织物上。结果表明，在有/没有催化剂次磷酸钠（SHP）的情况下，处理样品的折痕回复角和白度指数均高于 MA。通过 NMR 和 MS 谱图确认了 AMA 的化学结构。通过 （13）C NMR、MS、FTIR 和磷含量分析，研究了 AMA 与纤维素之间可能的交联机制。结果发现，AMA 可以通过形成酸酐中间体与纤维素形成酯键。同时，AMA 上的双键与另一个分子或 SHP 残留的 PH 的额外反应也有助于交联。基于分析提出了一个反应式。
