壳聚糖对涤纶织物的抗静电整理 本科生毕业论文 2013 PAGE II PAGE III 壳聚糖对涤纶织物的抗静电整理 摘要：涤纶织物通过壳聚糖整理能获得永久性抗静电效果，这为壳聚糖在染整行业中的应用开辟了一条新的途径。此外壳聚糖分子上大量的羟基和氨基等强极性基团的存在可使壳聚糖分子具有很高的吸湿性，在纤维表面形成连续的水膜，为空气中二氧化碳和纤维中存在的电解质提供了溶解场所，从而间接地提高了表面电导率。 讨论了壳聚糖用量、醋酸钠用量、丙二酸用量、焙烘温度、焙烘时间对壳聚糖抗静电效果的影响。壳聚糖用量6g/L左右时，涤纶织物能获得较好的抗静电效果且织物性能所受影响很小；醋酸钠用量10g/L左右时，涤纶织物能获得较好的抗静电效果且织物性能不受影响；丙二酸用量4g/L左右时，涤纶织物能获得较好的抗静电效果且织物性能不受影响；焙烘温度90℃左右时，涤纶织物能获得较好的抗静电效果且织物性能所受影响很小；焙烘时间10min左右时，涤纶织物能获得较好的抗静电效果且织物性能所受影响很小。最后通过正交实验得到最佳处理工艺：壳聚糖用量6g/L，催化剂醋酸钠12g/L，交联剂丙二酸3g/L，浴比1：30，浸渍5min，焙烘10min，焙烘温度90℃。该工艺可使涤纶织物具有明显且耐久的抗静电效果，且织物性能所受影响很小。 关键词：壳聚糖；涤纶织物 ；抗静电 Chitosan to antistatic finishing of polyester fabric Abstract: Permanent antistatic effect of fabric can be obtained through the chitosan finishing, this has made a new way for application of chitosan in the dyeing and finishing industry. Also there is a lot of hydroxy and amino groups and some polar of chitosan, Chitosan can have a high moisture absorption and form a continuous film of water on the surface of the fibers, This provides a place for carbon dioxide in the air and the electrolyte present in fiber solution, and thus indirectly improves the surface conductivity. The amount of sodium acetate, chitosan dosage, malonic acid, curing temperature and curing time were discussed. Chitosan dosage 6g / L or so, polyester fabrics can get better performance fabric antistatic effect and the impact is small; sodium acetate dosage 10g / L or so, polyester fabrics can get better antistatic effect and fabric performance is not affected; malonic acid dosage 4g / L or so, polyester fabrics can get better performance antistatic effect and the fabric is not affected; Baking temperature about 90 ℃, the polyester fabric can get better antistatic effect minimal impact on performance and fabric; curing time about 10min, the polyester fabric can get better performance fabric antistatic effect and the impact is small .Finishing process is determined by orthogonal test conditions: chitosan dosage 6g / L, sodium a
