摘　　要：自制衣康酸酐与降解壳聚糖合成了衣康酰化降解壳聚糖(IJCTA),结构表征后应用于亚麻织物防皱整理研究中,通过单因素分析实验优选出最优合成条件及整理工艺。结果显示:酰化物合成最佳投料比为3﹕1,取代度为0.913～0.928;整理最佳工艺条件:浴比1﹕20,w(IJCTA)=0.8%,w(NaH2PO2)=5%,175℃下焙烘3 min。N-Acylation modification to degradation chitosan was carried out with self-maded itaconic anhydride,and a new product named itaconic acylation degradation chitosan（IJCTA） was synthesized.It was used to crease-proof finish of linen after being characterized.The optimum conditions of synthesis and anti-crease finish process were explored by the single factor analysis： the best ratio（itaconic anhydride/degradation chitosan） is 3﹕1,the degree of substitution of the IJCTA was 0.913～0.928,Optimum finishing conditions： w（IJCTA-B）=0.8%,w（NaH2PO2）=5%,liquor ratio is 1﹕20,baking at 175℃ for 30 min.
