辉光和电晕低温等离子处理对羊毛表面性能的改性研究

讨论了等离子体技术的基本原理及在羊毛纤维表面处理上的应用,采用低温辉光等离子处理和低温射频单电极大气压放电处理2种不同的方法分别对羊毛纤维进行了处理,比较了不同的等离子体处理条件下处理后的羊毛纤维拉伸断裂强度、摩擦性能.应用拉曼光谱、扫描电镜(SEM)对等离子体处理后羊毛纤维的结构与性能进行了细致的研究.实验结果表明,经不同条件的等离子体处理后,羊毛纤维表面出现了不同程度的物理与化学刻蚀作用,纤维的表面性能得到了较大改善.

Study on wool surface modification with different low temperature plasma treatment

The low temperature plasma technology is an effective method in improving fiber surface performance.This article discusses basic principle of plasma technology and the application in the wool surface treatment.Through the treatment of wool with plasma technology under the low temperature atmospheric pressure corona discharge,it compared with the friction performance,capillarity effect and tensile breaking strength of wool after treatment.This experiment used two different methods(low temperature glow plasma processing and the low temperature atmospheric pressure corona discharge processes) to treat the wool fiber,and compared with the effect of wool performance under different plasma treatment condition.According to the use of scanning electron microscope(SEM) and Renishaw Invia Raman Microscope,this article carefully researched the structure and characteristics of wool treated by plasma.The experimental results showed that under the treatment of different plasma conditions,the wool fiber surface appeared the varying degree physics and chemical corrasion.Both surface performance and capillarity effect of wool fiber are improved greatly.
