Abstract: This article systematically introduces the development and testing principle of sensor method. Keywords: sensor method , water vapor permeability test , water vapor transmission rate , wvtr , testing methods 1. Development of Sensor Method Sensor method appears in the field of water vapor permeability testing in 1970s.Water vapor permeability is a measure of the passage of water vapor through a material. It is also known as water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR) - which is basically the mass of water vapor that is transmitted through a measured area in a specific unit of time under specified conditions of temperature and humidity. This paper focuses on the various methods to test moisture permeability and the analysis of the influencing factors of test results. Currently, outdoor sports are relatively active, and the outdoor clothing needed will be paid more attention. A good outdoor sportswear should have its own unique characteristics. Water vapor permeability is an important basic one..
ASTM E96-22: Standard Test Methods for Gravimetric Determination of Water Vapor Transmission Rate of Materials addresses two testing procedures for determining the water vapor transmission rate (WVTR) of numerous materials, both of which can be incredibly useful for knowing the potential risks posed on the materials in different humidity levels. Real time curves display of transmission rate, water vapour concentration, temperature and humidity; curves can be easily zoomed and moved. across or through a material, the greater the tendency for water vapor to migrate from the high pressure side to the low pressure side. EFFECT OF MATERIAL THICKNESS The perm ratings given are for stated thicknesses of materials. Generally, doubling material thickness halves water vapor transmission: if 1 inch of a material has a perm rating of .
the time rate of water vapor transmission through unit area of flat material or construction induced by unit vapor pressure difference between two specific surfaces, under specified temperature and humidity conditions • Water Vapor Permeability: the time rate of water vapor transmission through unit area of flat material ofWater Vapour Permeability Tester (WVP) is applied to test the water vapour permeability of all kinds of leather and shoe vamp as per ISO 20344. SATRA TM 172. For Water Vapour coefficient test, water vapour absorption tester is needed. Unuo Instruments supplies 2 types of Water Vapour Permeability Tester as below.

In recent years, the food industry has been undergoing major changes driven by new social and environmental demands. Nowadays, biodegradable packaging is perceived as the most feasible alternative for food .
Five testing instruments plus a new test apparatus were employed to evaluate the water vapor transport properties of fabrics with low, medium, and high vapor permeability. The test results show that the desiccant inverted cup method generated the highest water vapor transmission rate, followed by the new method, the dynamic moisture permeation .endow leathers with good water vapor permeability, compared with other synthetic clothing-materials [2]. The water vapor permeability cup is a popular method to determine the water vapor permeability. Ideal results may usually be obtained for the materials with a good humidity resistance. Marcinkowska et. al used the Water Vapor Perme-

Permeance is simply permeability divided by the material thickness in the direction of vapor flow; thus, permeability is a material property, whereas permeance depends on thickness. Permeability is measured with wet-cup, dry-cup, or modified cup tests. Specific test methods for measuring water vapor permeability are given in ASTM Standard E96.Air permeability is a crucial factor in textile assessment, impacting performance across various industries. This guide offers a comprehensive overview for many of you, including manufacturers, researchers, and consumers. Starting with fundamental concepts and measurement methods, we explore factors influencing air permeability, emphasizing its role in sportswear, filtration, and .
