摘　　要：纸张压光是一道工业整饰工序,它可以提高纸张表面的平滑度,改善其光泽度和印刷适性。本文讨论了压光对微观和宏观尺度上纸张粗糙度的影响以及这种表面改性与纤维形态之间的关系。实验原料为两种不同的纤维以及它们的混合物,采用光学轮廓仪表征纸张表面的性能。实验结果表明,在所测定的尺度范围内,压光均可以改善纸张的表面性能,通过简单的比例转换后,这些变化具有相关性,这一结果也适用于由混合纤维抄造的纸张。Calendering of paper is an industrial finishing process designed to smoothen its surface so as to improve gloss as well as printability. In this article, we describe how calendering affects paper roughness on both microscopic and macroscopic length scales. We also discuss how these modifications relate to the morphology of the fibers composing the paper sheets. The characterization of the surface is carried out using an optical profilometer and two different species of fibers, as well as their mixture, are used. We first show that calendering induces modifications of the surface on all length scales measured and that these modifications are related by straightforward transformations. We also show that these results hold for papers formed from a mixture of fibers.
