Abstract

Sanitary napkin is worn in direct skin contact and is an essential product for most women. Its liquid transport properties, depending on the material and design, affect skin wetness, skin irritating potential and comfortable feeling. Disposable sanitary napkin is commonly used whilst reusable sanitary napkin is also available in the market for sustainable reason. In this study, a measurement method originated from Forced Flow Water Transport Tester (FFWTT) was introduced which can characterize the direction of liquid transport of sanitary napkin under different pressure loadings. Disposable sanitary napkins with nonwoven or perforated film surface were compared against the reusable sanitary napkins. The results found that the reusable sanitary napkins tend to accumulate more next-to-skin moisture than the disposable sanitary napkin at equivalent loadings. Also, its transplanar wicking is poor. Besides, disposable sanitary napkins incorporated with superabsorbent polymer provide acceptable liquid transport property whilst those made of flex foam give the best performance.

改进的强制流水传输测试仪测量卫生巾的液体传输特性

抽象的

卫生巾直接与皮肤接触，对大多数女性来说是必不可少的产品。根据材料和设计的不同，其液体传输特性会影响皮肤的湿润度，刺激皮肤的潜力和舒适的感觉。通常使用一次性卫生巾，出于可持续的原因，市场上也有可重复使用的卫生巾。在这项研究中，介绍了一种源自强制流动水输送测试仪（FFWTT）的测量方法，该方法可以表征卫生巾在不同压力载荷下液体输送的方向。将具有非织造或穿孔膜表面的一次性卫生巾与可重复使用的卫生巾进行比较。结果发现，在相同的负荷下，与一次性卫生巾相比，可重复使用的卫生巾倾向于积聚更多的贴近皮肤的水分。而且，其跨面芯吸性差。此外，与超吸收性聚合物结合的一次性卫生巾提供可接受的液体输送性能，而由挠性泡沫制成的卫生巾则具有最佳性能。
