水分对常压射流等离子体处理羊毛针织物毡缩性的影响

Influences of moisture on the felting property of knitted wool fabric during jet plasma at atmospheric pressure treatment

通过扫描电镜(SEM)、原子力扫描探针显微镜(AFM)与纤维摩擦因数测定仪(FFT)描述了水分对常压射流等离子体(JPAP)处理亲水性羊毛的表面微观形态、表面粗糙度、纤维定向摩擦效应以及针织物毡缩性的作用。结果表明,湿态、干态及水浸处理,不同程度地有利于JPAP对羊毛的表面改性。尤其是湿态处理,对鳞片的刻蚀效果显著,对静态与动态定向摩擦效应(DFE)作用明显,但对纤维表面平均粗糙度的贡献略小,能够基本达到毡缩率小于8.0%的机可洗标准。

By means of scanning electron microscope （SEM）, atomic force scanning probe microscope （AFM） and fiber friction coefficient tester （ FFT）, this paper investigated the influences of moisture on the surface morphology, surface roughness, directional friction effect （DFE） and felting shrinkage of knitted wool fabric during the jet plasma at atmospheric pressure （JPAP） treatment. The result showed that the moisture will be beneficial to the surface modification of wool in different degree. Especially the wet JPAP processing, with significantly etching effect on scales, obviously static and dynamic directional friction effect, and relatively few surface roughness, can basically achieve the machine washable standard with felting shrinkage less than 8%.
