A novel chitosan derivative, O-acrylamidomethyl-N-[(2-hydroxy-3- dimethyldodecylammonium) propyl] chitosan chloride (NMA-HDCC), was synthesized by reacting chitosan (CTS) with epoxypropyl dodecyl dimethyl quaternary ammonium salt and N-methylolacryl amide (NMA). The chemical structure of the quaternized chitosan was analyzed by FTIR and NMR. The water soluble derivative can form covalent bonding with cellulosic fibers and bring quaternary salt groups onto the fibers. Anti-bacterial as well as salt-free reactive dyeing properties of the treated cotton samples were analyzed. The NMA-HDCC treated cotton fabrics showed durable antimicrobial functions even after 30 consecutive home launderings. The cotton treated with the chitosan and different chitosan derivatives showed improved uptakes, fixation rates, K/S values and fastness of reactive dyes without using auxiliary salt.
一种新型壳聚糖衍生物，O-丙烯酰胺甲基-N-[(2-羟基-3-二甲氧基十二烷基)丙基]壳聚糖氯化物（NMA-HDCC），通过壳聚糖（CTS）与环氧丙基十二烷基二甲基季铵盐和 N-羟甲基丙烯酰胺（NMA）反应合成。通过傅里叶变换红外光谱（FTIR）和核磁共振（NMR）分析了季铵化壳聚糖的化学结构。水溶性衍生物可以与纤维素纤维形成共价键，并将季铵盐基团引入纤维上。分析了处理后的棉样的抗菌和无盐活性染料染色性能。经过 30 次家庭洗涤后，NMA-HDCC 处理的棉织物仍具有持久的抗菌功能。用壳聚糖和不同壳聚糖衍生物处理的棉织物，在不使用辅助盐的情况下，提高了活性染料的上染率、固着率、K/S 值和牢度。
