Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Water Vapor Transmission Rate (WVTR) Testing of Sanitary Towel Substrate Materials In this article we will introduce the testing of water vapor transmission rate (WVTR) for two sanitary towel substrate materials according to ASTM E96 standards. The cup method was employed using a C360M Water Vapor Transmission Rate Test System. The test results indicate significant differences in moisture permeability between the two samples, impacting factors like breathability and comfort. Sanitary towel manufacturers prioritize consumer comfort and fluid management. Key factors influencing comfort include absorbency, leak prevention, breathability, and quickdrying properties. These characteristics are directly related to the materials used in the sanitary towel's different layers. This test focuses on the moisture permeability of sanitary towel substrate materials, a critical factor for breathability and comfort. The cup method, following ASTM E96 standards, was used to determine the WVTR of two samples. The test used substrate materials from two sanitary towel manufacturers, and was performed according to ASTM E96 - Standard Test Methods for Water Vapor Transmission of Materials (Cup Method). The testing Instrument was Labthink C360M Water Vapor Transmission Rate Test System. The average WVTR for the two samples were: sample 1: 601.4813 g/(m²·24h), sample 2: 1384.0073 g/(m²·24h)

Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 The test results demonstrate a significant difference in moisture permeability between the two sanitary towel substrate materials. This variation directly impacts the breathability of the final product, influencing user comfort. The C360M Water Vapor Transmission Rate Test System proved efficient, allowing for simultaneous testing of multiple samples and providing reliable data. The C360M Water Vapor Transmission Rate Test System is applicable to a broad range of materials beyond sanitary towel substrates. Here are some...
