摘　　要：利用壳聚糖和双氰胺成功地合成了一种壳聚糖双胍盐酸盐(CGH),对合成反应机理及副反应进行了讨论,应用红外光谱确认了CGH的结构,将合成的CGH对羊毛织物进行预处理,并用兰纳素活性染料进行轧染微波固色。研究预处理工艺(包括CGH浓度,交联剂的种类,焙烘温度,浸渍时间,预处理溶液pH)对羊毛织物染色性能的影响,确定预处理的最佳工艺。即采用pH值为4.0的0.6%的CGH,在柠檬酸作交联剂的条件下浸渍10min,80℃烘干5min,100℃焙烘3min。结果表明,用CGH对羊毛织物进行预处理,可以大大提高活性染料对羊毛织物染色的K/S值,染色织物的摩擦牢度和皂洗牢度略有下降。Chitosan biguanidine hydrochloride （CGH） was synthesized successfully with chitosan and dicyandiamide. Its synthetic mechanism and side reaction were discussed. The structures of CGH were characterized by FT-IR. The wool fabric was pretreated by the synthesized CGH and color fixing was done by the lanasol reactive dyes. Influence of pretreatment conditions including concentration of CGH, kinds of cross-linking agent, curing temperature, dipping time, pH value on dyeing effect of wool fabrics was investigated and the optimum conditions for pretreatment were obtained as follows： wool fabric was treated with 0. 6~ CGH and crosslir^king agent citric acid （CA） at pH 4. 0 for 10min, and then dried at 80℃ for 5min, cured at 100℃ for 3min. The results indicated that, after being treated with CGH, higher K/S value during dyeing the wool fabric with reactive dyes can be obtained, but the rubbing fastness and soaping fastness was reduced slightly.
