棉织物的拒水拒油清洁化整理工艺研究

A Study on Cleaning Finishing Process of Cotton Fabric with Water and Oil Repellent

通过轧烘工艺对棉织物进行了拒水拒油整理,测试了不同焙烘温度、焙烘时间、整理液p H值及浓度对织物水油接触角的影响。试验表明,整理剂浓度为30 g/L、p H为6.67、轧液率80%、140℃下焙烘8 min时,整理后棉织物的水油接触角分别达到143.33°和134°,整理效果最佳。扫描电镜观察表明,经拒水拒油整理后的棉纤维表面光滑,整理剂的成膜性较好,具有较好的拒水拒油性能。

Water and oil repellent finishing is done on cotton fabric by pad-dry-baking process. The influences of baking temperature, baking time, p H value and concentration of finishing liquid on oil water contact angle of fabric are analyzed. The result shows that the optimized water/oil repellent finishing process of cotton fabrics is as follows： the concentration of finishing agent is 30g/L, p H value is 6.67, rolling liquid rate is 80%, and the baking time is 8 minutes under 140℃. After finishing, the oil and water contact angle of the cotton fabrics can reach up to143.33 degrees and 134 degrees respectively, and at this time the finishing effect is the best. Scanning electron microscopy（SEM） reveals that after water and oil repellent finishing, the surface of the cotton fiber becomes smooth, the finishing agent has good film-forming ability, and it has better water and oil repellent performance.
