摘　　要：在一定的激光能量密度下 ,激光会使纤维形成周期性柱状表面结构。激光处理后的化纤再经过特殊处理可以增加它的拒油性。本文研究了不同能量密度下 30 8nm紫外激光对表面纹理化的影响 ,为保证在较大面积内获得均匀辐照 ,提出了多次扫描叠加法 ,获得优于 8.4Under certain energy density,the original smooth surface of the polyester changed its morphology to a rather regular rolllike structure perpendicular to the fiber axis after the treatment. By further chemical treatment,its rejectingoil quality was improved The dependence of characteristic surface data on 308 nm UV laser energy density was studied. In order to gain uniform irradiation,the method of scanning to and fro was given. The uniformity of 8.4% was gained.
