用原位合成的氯乙烷（AA）制备了三种乙基壳聚糖（ECSs）。通过浸轧-干燥-固化技术将每个ECS施加在100%棉织物上。采用方差分析的方法，测定了AA（0.1-2.1 mmol）和壳聚糖（CS）（0.1-2.1 mmol）的浓度对防粘效果的影响。通过FTIR、H-1 NMR、XPS、SEM、DSC和热重分析等手段证实了烷基化反应和接枝反应的机理。通过定量方法（卷取度、回复角、拉伸强度和效果持久性），揭示了各ECS作为防毡缩剂的性能。与见证试样相比，ECS具有更高的回复角和抗拉强度。接枝在棉上的ECS的耐久性已经通过在苛刻的工作条件（100 ° C，60分钟）下用非特异性（酸性/阴离子和阳离子）染料染色的良好能力和良好的抗微生物能力来证明。(C)2015爱思唯尔有限公司版权所有。
Three ethyl chitosans (ECSs) have been prepared using the ethyl chloride (AA) that was obtained in situ. Each ECS was applied on a 100% cotton fabric through a pad-dry-cure technology. Using the ANOVA as statistic method, the wrinkle-proofing effects have been determined varying the concentrations of AA (0.1-2.1 mmol) and chitosan (CS) (0.1-2.1 mmol). Alkylation and grafting mechanisms have been confirmed by the results of FTIR, H-1 NMR, XPS, SEM, DSC and termogravimetric analyses. The performances of each ECS as wrinkle-proofing agent have been revealed through quantitative methods (taking-up degree, wrinkle-recovering angle, tensile strength and effect's durability). The ECSs confer wrinkle-recovering angle and tensile strength higher than those of the witness sample. Durability of ECSs grafted on cotton have been demonstrated by a good capacity of dyeing with non-specific (acid/anionic and cationic) dyes under severe working conditions (100 degrees C, 60 min) and a good antimicrobial capacity.
