Moisture in textile materials worn close to the skin greatly influences our daily comfort. The measurement of moisture in textile materials is therefore of great interest, for example, to determine the amount of perspiration in clothing or car seats, the wound fluid in dressings, or even the urine in diapers or bed linen. All these applications require a robust moisture measurement method, which is harmless to humans and measures in thin layers. One method ideally suited to fit these requirements is the transient‐heat moisture sensing (THMS) method. Herein, a miniaturized and evolved adaption of the THMS method is shown. The measurement system presented herein is optimized for low energy consumption and portability. The working principle of this measuring system is demonstrated by conducting a simple test to investigate the transplanar wicking of eight fundamentally different but garment‐typical textiles. The THMS method and its ability to measure in thin layers that is ideally suited to measure moisture in thin layers are shown. Finally, it lays a foundation to enable a multitude of future applications, wherever moisture (e.g., sweat) is to be measured with high accuracy and with a wearable system close to the human skin.

小型且基于热的测量系统,用于测量纺织材料中的水分

靠近皮肤穿着的纺织材料中的水分会极大地影响我们的日常舒适性。因此,对纺织材料中水分的测量非常感兴趣,例如,以确定衣服或汽车座椅上的汗水量,敷料中的伤口液甚至尿布或床单中的尿液。所有这些应用都需要一种健壮的水分测量方法,该方法对人体无害,并可以薄层测量。满足这些要求的一种理想方法是瞬态热湿感测(THMS)方法。在此,示出了THMS方法的小型化和改进的适应。本文介绍的测量系统针对低能耗和便携性进行了优化。通过进行简单的测试来研究八种根本不同但服装典型的纺织品的经面芯吸,证明了该测量系统的工作原理。显示了THMS方法及其在薄层中的测量能力,该方法非常适合测量薄层中的水分。最后,它为实现将来的各种应用奠定了基础,无论在哪里都可以高精度测量湿度(例如汗水),并且可穿戴系统靠近人体皮肤。
