通过接枝率、接触角、透水时间、拉伸应力应变、ESCA的测定以及水冲击实验研究了在DCP和BP等存在下电晕放电引发含氢硅油接枝PET织物及其拒水性能。实验结果表明 :电晕放电能有效引发含氢硅油在PET织物表面的接枝共聚反应 ,随电晕放电处理时间的延长 ,PET织物表面接枝率增大 ;接枝后PET织物拒水效果明显增强 ;电晕放电引发接枝改性后PET织物无损伤 ,力学性能基本保持不变。
The grafting ratio, contact angle, water breakthrough time, tensile stress and strain, ESCA measurement and water impact test were used to study the corona discharge initiated hydrogenated silicone oil grafted PET fabric and its water-repellent properties in the presence of DCP and BP. The experimental results show that the corona discharge can effectively initiate the graft copolymerization of hydrogenated silicone oil on the surface of PET fabric. With the extension of corona discharge treatment time, the grafting rate of PET fabric increases. The water repellency of PET fabric after grafting is obvious Enhanced; corona discharge induced graft modified PET fabric without damage, the mechanical properties remained unchanged.
