以壳聚糖和缩水甘油基三甲基氯化铵为原料，制备了水溶性的N-（2-羟基）丙基-3-三甲基氯化铵壳聚糖（HTCC）。傅里叶变换红外光谱分析光谱证实，缩水甘油基三甲基氯化铵通过取代反应接枝到壳聚糖的氨基上（Zhao等人，Int J Pharm 2010，393，268; Montazer和Afjeh，J Appl Polym Sci 2007，103，178）。将所得壳聚糖衍生物用于棉织物的改性，以改善水性涂料喷墨印花和抗菌性能。扫描电子显微镜图像显示HTCC粘附在棉织物表面并形成薄膜结构。在印花棉上的K/S值从3.20提高到4.87，表明该方法获得了较高的得色量。改性样品的摩擦牢度和耐洗牢度均优于对照棉织物。当改性后织物的线宽为0.5 × 103 μ m时，经向和纬向的线条清晰度分别提高了16.5%和12.6%。样品也表现出良好的抑菌性能，当HTCC浓度为0.8%时，对金黄色葡萄球菌和大肠杆菌的抑菌率均在95%以上。抗菌效果被发现是持久的20个洗涤周期。但改性棉织物的手感略有下降。(c)2012 Wiley Periodicals，Inc.应用聚合物科学杂志，2012年
The water-soluble N-(2-hydroxy)propyl-3-trimethylammonium chitosan chloride (HTCC) was prepared by chitosan and glycidyl trimethyl ammonium chloride. Fourier-transform infrared spectroscopic analysis spectrum confirmed that glycidyl trimethyl ammonium chloride was grafted to the amino groups of chitosan via substitution reaction (Zhao et al., Int J Pharm 2010, 393, 268; Montazer and Afjeh, J Appl Polym Sci 2007, 103, 178). The obtained chitosan derivative was used to modify cotton fabrics for improving aqueous pigment-based inkjet printing and antibacterial properties. Scanning electron microscope images showed that HTCC was adhered onto the cotton fabrics surface and formed film structure. The K/S value on printed cotton substrates increased from 3.20 to 4.87, which indicated that higher color yield was achieved in this way. Modified samples performed better crocking fastness and laundering fastness than the control cotton fabrics. The line definition of modified cotton fabrics respectively, improved 16.5% and 12.6% in the warp and weft direction as the specified line width was 0.5 x 103 mu m. Samples also showed good antibacterial potential, the inhibitory rate for Staphylococcus aureus and Escherichia coli were both more than 95% when the concentration of HTCC used in the pretreatment solution was 0.8%. The antibacterial effect was found to be durable for 20 laundering cycles. However, the hand feeling of modified cotton fabrics presented a slight decrease. (c) 2012 Wiley Periodicals, Inc.
