Carboxymethyl chitosan (CMCS) was prepared with a view to develop a multifunctional finish on saponified polyethylene terephthalate (PET) fabric. CMCS was synthesized by chemical reaction with chloroacetic acid, and its chemical structure was characterized by Fourier Transform Infrared Spectrum (FTIR) and nuclear magnetic resonance (NMR). CMCS was grafted on saponified PET fabric using 3-(3-dimethylaminopropyl)-1-ethylcarbodiimide hydrochloride (EDC)/N-hydroxysuccinimide (NHS) and polyethylenimine (PEI)/glutaraldehyde (GA) as cross-linking agent. FTIR, scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analyses confirmed CMCS grafting on saponified PET fabric surface. TGA indicated saponification and CMCS grafting did not affect thermal property of PET fabric. The CMCS grafting greatly improved wettability, antistatic property of saponified PET fabric without harmful effect on their physico-mechanical properties.
羧甲基壳聚糖（CMCS）被制备以开发对皂化的聚对苯二甲酸乙二醇酯（PET）织物的多功能整理。CMCS 通过与氯乙酸的化学反应合成，并通过傅里叶变换红外光谱（FTIR）和核磁共振（NMR）对其化学结构进行了表征。使用 3-（3-二甲基氨基丙基）-1-乙基碳二亚胺盐酸盐（EDC）/N-羟基琥珀酰亚胺（NHS）和聚乙烯亚胺（PEI）/戊二醛（GA）作为交联剂，CMCS 接枝到皂化的 PET 织物上。FTIR、扫描电子显微镜（SEM）和能谱分析（EDX）证实了 CMCS 接枝到皂化 PET 织物表面。TGA 表明皂化和 CMCS 接枝并未影响 PET 织物的热性能。CMCS 接枝极大地提高了皂化 PET 织物的润湿性和抗静电性，而对其物理机械性能没有有害影响。
