Abstract This study analyzed the effect that pulp fibers have on the surface softness component of hygiene paper. The surface softness component has more of an influence on the evaluation of subjective softness results than the bulk softness component. Using the surface softness measurement technique, this study aimed to evaluate the effect that fibers have on the softness of hygiene paper substrate via objective numerical values to measure the surface softness component of hand sheets composed of various pulp species. The results indicate that coarseness effects had the largest effect on softness among the various fiber characteristics, such as average fiber length, width and coarseness. As fiber coarseness increased, a rough surface formed, which resulted in an increase in the mean deviation from the average friction (MMD). Nonwood fibers had long fiber length and low coarseness, which enables the production of hygiene paper with high strength and softness. This study hopefully could lead to the development of various process technologies that may improve the softness of hygiene paper products.

纸浆纤维对卫生纸表面柔软度成分的影响

摘要 本研究分析了纸浆纤维对卫生纸表面柔软度成分的影响。表面柔软度分量比整体柔软度分量对主观柔软度结果的评价影响更大。本研究使用表面柔软度测量技术，旨在通过客观数值来测量纤维对卫生纸基材柔软度的影响，以测量由各种纸浆种类组成的手抄纸的表面柔软度成分。结果表明，在平均纤维长度、宽度和粗度等各种纤维特性中，粗度对柔软度的影响最大。随着纤维粗度的增加，会形成粗糙的表面，导致平均摩擦力（MMD）的平均偏差增加。非木纤维纤维长度长，粗度低，可生产强度高、柔软度高的卫生纸。这项研究有望促进各种工艺技术的发展，从而提高卫生纸产品的柔软度。
