低温等离子体处理对纺织品磁控溅射镀膜的影响

Impact of low temperature plasma treatment on magnetron sputter coating of textiles

为提高织物与溅射膜的结合牢度,文章应用低温等离子体技术对涤纶、棉和蚕丝三种织物进行表面改性。比较了表面改性对三种薄膜织物的耐摩擦和耐皂洗牢度的作用,并应用SEM和EDS分析技术研究了表面改性对不同纤维与溅射膜牢度影响不同的根本原因:纤维本身理化性质的差异性。高能溅射粒子使热塑性涤纶纤维上的粒子沉积点瞬间软化,黏结溅射粒子,表面改性使纤维的比表面积增大,包埋和黏结溅射粒子的作用更显著。棉和蚕丝纤维对溅射粒子无黏结作用,水分子的侵入削弱纤维与溅射粒子间的作用力,经改性后的纤维表面具有一定的脆弱点,皂洗时脆弱纤维更易溶落,纳米粒子也随之脱落。

To improve the bonding fastness of magnetron sputter coating on fabric surfaces,low temperature plasma(LT-Plasma)technology was applied in the surface modification of three typical fabrics of terylene,cotton and natural silk.The effects of surface modification on the abrasion resistance and soap fastness of three kinds of magnetron sputtering coated fabrics were compared,and the underlying reasons for different effects of surface modification on the bonding fastness of magnetron sputter coating on different fabrics were studied using SEM and EDS analytical techniques:the difference in the physical and chemical properties of fibers.High-energy sputtering particles make the deposition point on the thermoplastic polyester fiber softened instantaneously and bond the sputtering particles.Surface modification increases the specific surface area of fiber,so the embedding and bonding effect on sputtering particles is more significant.Cotton and silk fibers have no bonding effect on magnetron sputtering particles,and the intrusion of water molecules weakens the interaction force between fibers and nanoparticles in the soaping process,and the fiber molecules treated by LT-Plasma have certain fragile points.In the soaping process,fragile fibers dissolve more easily,and the nanoparticles fall off accordingly.
