摘要

本研所提之欽可法測定衛生紙之膨鬆柔軟度原理係基於固定一長150mm，寬25mm之供試片之一端，另一自由下垂端輕觸高感度電子天平（精度: 0.0lg）秤盤之表面，使上下鋏具間之距離為130mm，然後緩降上方鋏具使紙樣微彎2mm至128mm程度，此時天平承受負載之讀數大小即為該試紙之膨鬆柔軟度（單位以mgf示之，讀數小表示高膨鬆柔軟度）。本法所測得之數值與由慣用之傾斜法（Cantilevermethod）所測定之與膨鬆柔軟度有關之挺度具甚佳之相關性（r=0.97）。

The Chinke test we proposed for evaluating bulk softness of tissue paper is based on the load applied by the free bottom side of a paper strip (dimension 150 X 25 mm) on the weighing pan of a highly sensitive (precision: 0.01 g) electronic balance, of which top side fixed by a clamp. A slight bending of the paper caused by the shorter distance (128 mm) between the upper fixed clamp and the weighing pan results in a load variation (expressed as mgf) which is found to correspond to the bulk softness. A good correlation (r=0.97) of bulk softness of tissue papers determined by Chinke method and Cantilever test was also found in this study.
