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。 Paper calendering is an industrial finishing process that improves the smoothness of the paper surface and improves its gloss and printability. This paper discusses the effect of calendering on paper roughness at the microscopic and macroscale scales and the relationship between this surface modification and the fiber morphology. The experimental materials were two different fibers and their mixtures, and the optical profiler was used to characterize the surface properties of the paper. The experimental results show that calendering improves the surface properties of the paper over a range of measured scales and that these changes are relevant after a simple scale-up and this result is also valid for sheets made from mixed fibers.
