Anti-crease Finishing of Cotton Fabrics Based on Crosslinking of Cellulose with Oxidized Sucrose

ABSTRACT

In anti-crease finishing, the hydrophilicity of cotton fabric treated with traditional anti-crease finishing agents such as dimethylol dihydroxy ethylene urea (DMDHEU), 1,2,3,4,-butanetetracarboxylic acid (BTCA), citric acid (CA) was reduced significantly. Oxidized sucrose (OS) was prepared by partial oxidation with sodium periodate. The OS was used as a hydrophilic cross-linking agent instead of conventional anti-crease agents. The chemical structure of the OS characterized by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance, and aldehyde groups were found in the OS. The effects of OS mass concentration, catalyst mass concentration, pH, curing temperature and curing time on the crease recovery angle (CRA), whiteness index (WI) and strong retention rate (TS %) of fabrics were studied. The optimal finishing process was an OS mass concentration of 150 g/L, a catalyst mass concentration of 20 g/L, pH 3 and curing for 3 min at160°C. The OS-treated cotton fabrics could obtain a maximum CRA of 245°, WI of 82.8 and TS% of 65%. Compared with DMDHEU, glutaraldehyde, BTCA and CA finishing fabrics, the OS finishing fabric had a shorter wetting time of 5.01 s and a higher water retention.

摘要

在抗皱整理中，用传统抗皱整理剂二羟甲基乙二醇脲（DMDHEU）、1,2,3,4、-丁烷四羧酸（BTCA）、柠檬酸（CA）处理后，棉织物的亲水性显著降低. 采用高碘酸钠部分氧化法制备氧化蔗糖（OS）. 用OS代替传统的抗皱剂作为亲水性交联剂. 用傅立叶变换红外光谱和质子核磁共振对OS的化学结构进行了表征，发现OS中含有醛基. 研究了OS质量浓度、催化剂质量浓度、pH值、硫化温度和硫化时间对织物折皱回复角（CRA）、白度指数（WI）和强力保留率（TS%）的影响. 最佳整理工艺为OS质量浓度150g/L，催化剂质量浓度20g/L，pH值3，160℃固化3min. 经OS处理的棉织物的最大CRA为245°，WI为82.8%，TS%为65%. 与DMDHEU、戊二醛、BTCA和CA整理织物相比，OS整理织物的润湿时间短于5.01s，保水性更高.
