This study proposes a method to determine the two-dimensional absorption capacity of paper towels. Individual plies were tested to minimize the effects of transverse wicking on wetting. The method involves arbitrary point source injection of liquid into the towel surface while recording microscopic images of the wetted areas. The samples were selected from the main manufacturing processes: conventional wet pressing and through-air drying. Wetting graphs that illustrate the dynamic and static wetting behaviors were generated. The driving force was found to have a negligible effect on the maximum wetted area. The maximum wetted area and the paper grammage were used to determine the two-dimensional absorption capacity. The results were validated by the basket-immersion test method.

纸巾的润湿：一种确定二维吸收能力的方法

本研究提出了一种确定纸巾二维吸收能力的方法。对单个层进行了测试，以尽量减少横向芯吸对润湿的影响。该方法包括将液体任意点源注入毛巾表面，同时记录润湿区域的显微图像。样品选自主要制造工艺：传统的湿压和通风干燥。生成了说明动态和静态润湿行为的润湿图。发现驱动力对最大润湿面积的影响可以忽略不计。最大润湿面积和纸张克重用于确定二维吸收容量。结果通过篮浸试验法进行验证。
