Friction resistance and anti-UV properties of electron beam evaporation deposited film on fabrics

利用电子束蒸发沉积法在不同的织物表面形成镍铬金属膜,制备具有抗紫外线辐射功能的柔性材料。通过SEM、EDS观察以及图像处理技术,比较了纤维原料及织物成形方式对电子束蒸发沉积膜的耐磨稳定性影响,并进一步分析了镀膜工艺对耐磨稳定性及抗紫外线性能的影响。结果表明:使用电子束蒸发沉积法在纤维基底材料上可形成均匀的、金属外观的薄膜,并且涤纶针织结构有利于提高金属膜在纤维表面的耐磨稳定性;当溅射时间为20 min、溅射电子束流为280 m A时,金属薄膜与基底的结合牢度好,可经受2 000次以上的摩擦,当摩擦约2 500次时,其UPF值超过40,具有较优异的持久功能性。

A Ni Cr metallic film was formed on the surface of different fabrics by electron beam evaporation deposition method to prepare flexible materials with anti-ultraviolet（ UV） properties. SEM,EDS,and image processing technology were used to compare influence of fiber materials and fabric forming methods on friction resistance stability of electron beam evaporation deposited films. The influence of coating parameters on friction resistance stability and anti-UV properties were also analyzed.The results show that a uniform film with the metallic appearance is formed on the fiber substrate by the electron beam evaporation deposition method,and the polyester knitted structure is conductive to the improvement of the film friction resistance stability. When the sputtering time is 20 min and the sputtering beam current is 280 m A,the metal film has good bonding strength with the substrate,and can standing for friction of 2 000 times. Moreover,UPF is over 40 after about 2 500 friction cycles,and the film has excellent lasting functionality.
