3.1.1 Discussion—Permeability is a property of a material, but the permeability of a body that performs like a material may be used. Permeability is the arithmetic product of per-meance and thickness. water vapor permeance—the time rate of water vapor transmission through unit area of flat material or constructionAir 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 .
water vapor permeanceÑthe time rate of water vapor transmission through unit area of ßat material or construction induced by unit vapor pressure difference between two speciÞc surfaces, under speciÞed temperature and humidity conditions. DiscussionÑPermeance is a performance evaluation and not a property of a material. 1 These test methods . 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.

for water vapor it is given in units of mass of water vapor. Sometimes, the amount of permeant is given in moles. Sometimes the term “diffusion coefficient” is used incorrectly instead of permeability, which are different properties, leading to additional confusion. Another complication involves the water vapor transmission rate (WVTR).Keywords: Water vapor permeability; Water vapor transmission rate; Cup method; Membrane; ASTM E96. 1. Introduction The global energy consumption has risen significantly in the past decades due to the growth of population, to the increase in the thermal comfort desire and to the rapidly developing economy.
The water vapour permeability index is calculated by expressing the water permeability of textiles as a percentage of the water vapour permeability of a reference fabric which is tested in a water vapor permeability test. After the water permeability test for fabric, the water vapour permeability of the fabric can be obtained according to the .
Electrolytic method is the one that employs electrolytic cell sensor to test specimen water vapor permeability. Its testing principle is shown as follows (see Fig 2): the testing chamber is divided into a dry chamber and controlled humidity chamber with specimen.
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 ofendow 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.

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.Water vapor permeability is one of the main performance indexes of package materials. As people are attaching more importance to the damp proofing and waterproofing of products, package materials with smaller water vapor permeability becomes the f.3us of package material development and application and is receiving more and more concentrations in .
