低温等离子体改性山羊绒纤维表面微观结构的研究

Study on the surface microstructure of low-temperature plasma on cashmere fiber

将山羊绒纤维利用空气低温等离子体进行表面改性,采用SEM、XPS等手段,分析研究改性前后纤维的表面特性。结果表明:经过等离子体不同条件处理,纤维表面的鳞片结构受到不同程度的破坏,表面元素成分和元素比例也发生改变,在纤维表面引入了大量的CO、C—O—H等亲水性极性基团,可显著改善表面润湿性。

The surface of cashmere fiber was modified using air-low-temperature plasma.The effects on cashmere fiber surface modification before and after treatment were studied,and the surface properties were characterized by scanning electronic microscope（SEM） and X-ray photoelectron spectroscopy（XPS）.The results showed that different conditions revealed the damage of scale structure of cashmere,and the surface elemental composition and elemental ratio changed after different conditions of air-low-temperature plasma treatment.The surface oxygen polar group of cashmere including C O and C—O—H increased,which maked the infiltrating property enhanced remarkably.
