摘要： The present invention relates to razor blade cutting edges and methods of producing edges exhibiting improved shave performance longevity and lower cutting forces. Conventional razor blades have increasing cutting forces with use due to the outer coating wear and adhesion loss. Blade edges produced according to the novel process exhibit significantly lower cutting forces when subjected to wool felt cutting shaving simulation, which correlates to more comfortable shaves initially and over the life of the blades. The present invention treats razor blade edges having a first adherent polyfluorocarbon coating with a first solvent to partially remove the polyfluorocarbon coating, adds a second polyfluorocarbon coating, heats, and treats the blade edge with a second solvent providing a final blade edge having a thin, uniform polyfluorocarbon coating. Preferred solvents include perfluoroalkanes, perfluorocycloalkanes, and perfluoroaromatic compounds having a critical temperature or boiling point above the dissolution temperature for the polyfluorocarbon in the solvent.

摘要翻译： 剃刀刀片切割刃本发明涉及剃须刃切割刃和产生边缘的方法，其具有改善的剃须性能，寿命和切割力。 传统的剃刀刀片由于外部涂层磨损和粘附损失而具有越来越多的切割力。 根据新颖工艺生产的刀刃在经受羊毛毡切割模拟时显示出显着较低的切削力，其与最初和在刀片寿命期间更舒适的剃须相关。 本发明用具有第一溶剂处理具有第一粘附多氟碳涂层的剃刀刀片边缘部分地去除多氟碳涂层，添加第二多氟碳涂层，用第二溶剂加热和处理刀片边缘，提供具有薄的， 均匀多氟碳涂层。 优选的溶剂包括具有高于溶剂中多氟碳烷的溶解温度的临界温度或沸点的全氟烷烃，全氟环烷烃和全氟芳族化合物。
