【摘要】 本文设计合成了一种适用于纤维素纤维的抗菌剂聚六亚甲基双胍盐酸盐。该抗菌剂以己二胺盐酸盐和双氰胺为主要原料，目标产物属于绿色环保型，可以借助于柠檬酸与纤维发生作用，使抗菌效果具有耐久性。本文探索了它的合成工艺，研究了其应用工艺，取得了满意的效果。抗菌剂PHMB是一种淡黄色的固体粉末，其水溶液为澄清、略带黄色的粘性液体。通过变化反应条件，测定反应产率，得出最佳的反应条件。对抗菌剂PHMB的结构、物性和化学性能等分别做了分析，采用轧、烘、焙工艺对棉织物进行抗菌整理，并详细研究了其对棉织物的整理工艺，通过比较得出了最佳工艺处方。得到的抗菌织物按照中华人民共和国纺织行业抗菌标准，FZ／T 73023-2006进行抗菌测试，抗菌剂对不同细菌的抑菌效果金黄葡萄球菌＞大肠杆菌＞白色念珠菌，水洗50次后，抑菌率依然在85％以上。本论文系统研究胍类聚合物整理棉织物的机理、工艺、改善整理效果的方法、整理后棉织物的物理机械性能和抗菌性能。对加快环保纺织品的生产具有实用意义。更多还原

【Abstract】 In this paper, a new generation of antibacterial agents—Polyhexamethylene Biguanidine hydrochloride, which is suitable forthe application of cotton fabrics, was synthesized by the reaction ofdicyandiamide and hexamethylenediamine hydrochloride. It can act oncotton with the help of citric acid, and the treated cotton has good abilityof antibacterial. The best synthesis conditions and application processwere selected by mathematic method, and satisfying effect was acquired.The reaction product exists as primrose yellow power, and is easy tobecome soluble in water. Its solution is a kind of clear and transparentviscose liquid. According to change reaction conditions, production ratewas tested and the best reaction process was obtained. Structure,condition of synthesis and process of reaction was analyzed in this thesis.Process of synthesis and application of PHMB is simple. And it can beapplied to cotton fabric with crosslinking agents through padding, dryingand curing process, and the best treated process was obtained bycomparing. The FZ/T 73023-2006 standard was used to test antibacterialproperty of treated cotton, the result shows that cotton fabric treated byPHMB obtains better anti-Escherichia and anti-Coti, poorer anti-Bacillus.The antibacterial rate was above 85% after 50 times washing.This paper investigates on the mechanism, technics, the way toimprove treatment effect, mechanical and antibacterial properties ofguanidine antibacterial treatment, which will push the development ofenvironmental friendly textile product.更多还原
