氟烷基改性含氢硅油对大麻织物的整理
|
摘要
在钯碳加氢催化剂的作用下,根据硅氢加成的方法合成氟烷基改性含氢硅油,并将合成的氟烷基改性含氢硅油进行乳化,采用正交试验得到较佳的乳化条件为:乳化时间150 min,复合乳化剂含量5%,乳化温度40℃,氟烷基改性含氢硅油含量4%。将已经乳化的氟烷基改性含氢硅油对大麻织物进行整理,通过测定大麻织物的断裂强度、弹性回复角、弯曲长度、润湿接触角和白度,分析得出较佳的整理工艺为:焙烘时间3 min,整理液质量浓度90 g/L,焙烘温度180℃。利用扫描电镜对整理后的大麻织物进行表征,结果显示整理后的大麻织物具有较好的服用性能。
Fluoroalkyl modified hydrogen silicone oil was synthesized by hydrosilylation reaction with Palladium carbon hydrogenation as catalyst, the fluoroalkyl modified hydrogen silicone oil was emulsified and orthogonal test emulsifying was used to get the best emulsification conditions. Through data analysis, the optimized emulsification condition was: 150 min stirring time, 5% emulsifier, 40 ℃ emulsifying temperature, 4% fluoroalkyl modified hydrogen silicone oil. Finishing of fluoroalkyl modified hydrogen silicone oil was adopted to treat hemp fabric, by measuring breaking strength, elastic recovery angle, bending length, wetting contact angle and whiteness, the optimum finishing process is curing at 180 ℃ for 3 min, finishing solution 90 g/L. Hemp fabrics were characterized by scanning electron microscopy(SEM). The results show that the treated hemp fabric had good performance.
