常压等离子射流处理羊毛织物的润湿性及其均匀性

Study on uniformity of wettability improvement of wool fabric treated by atmospheric pressure plasma jet

文章探讨了工艺参数对常压等离子射流处理羊毛织物的润湿性及其均匀性的影响。改变常压等离子射流处理的时间、氧气流速和喷头与基体间距离3个工艺参数,分别处理羊毛机织物后,测定处理前后织物对水滴的吸收时间,数码相机拍摄水滴在织物表面的扩散情况,扫描电子显微镜和X射线光电子能谱来探测纤维表面发生的物理和化学变化。结果表明,随着氧气流速和喷头与基体间距离的增加,羊毛织物的润湿性及其均匀性先变好后变差,随着处理时间的增加,羊毛织物的润湿性及其均匀性变好。

The influence of process parameters on uniformity of wettability improvement of wool fabric treated by atmospheric pressure plasma jet（APPJ） wettability was explored.The wool fabrics were treated by APPJ under different oxygen flow rate,jet-to-substrate distance and treatment time.The wet-out time of wool fabrics before and after APPJ treatment was measured.The diffusion photos of water drop on wool fabric surface were taken by digital camera.The morphological and chemical changes on the fiber surface were characterized by scanning electron microscopy（SEM） and X-ray photoelectron spectra（XPS） respectively.It was concluded that the uniformity of wettability improvement of wool fabric treated by APPJ increased and then decreased with the increasing oxygen flow rate and jet-to-substrate distance and increased with the increasing treatment time.
