Without dry oven. +86-21-6420 0566 [email protected] If moisture permeability is poor, sweat on the body’s surface is not easily dispersed, making people feel hot and uncomfortable. Sportswear, outdoor activity wear, and bedding all require fabric water-vapor permeability. Water-Vapor Permeability Test Method. Standard textile water-vapor permeability testing methods mainly include: 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..HONG KONG, China - Sept. 30, 2013 - PRLog-- Many outdoor jackets or rainwear may be labeled with functional claims such as waterproof breathable.The shell fabrics may be treated with finishes, coating or lamination to achieve the waterproof breathable function. However, if an improper treatment is applied, it may reduce the breathability and therefore inhibit the .
Common test methods at home and abroad for water permeability Moisture absorption (desiccant) method Dry the desiccant (anhydrous calcium chloride) particles (0.63-2.5) mm in an oven at 160°C for 3 hours to keep the desiccant 100% dry. The water vapour permeability test measures how well fabrics let moisture through. It does this at different temperatures and humidities. It simulates how well fabrics move water vapor. Bodies release it when they sweat. They release it to the outside. Moisture permeability is the quality of water vapor transfer on both sides of the fabric.
GENEVA — September 30, 2013 — SGS provides a technical update on common water vapor permeability testing methods and procedures for rainwear and other functional fabrics or textiles. . – Upright cup for water permeable fabric – Inverted cup for water impermeable fabric . JIS L 1099 – Cup methods The principle was as follows: potassium acetate was used as a desiccating agent.The PTFE film is made into a vapor permeable cup with a rubber ring around the plastic cup.Before coating the cup, put enough potassium acetate solution into a water-vapor permeable cup that fills about two-thirds of the cup's volume.Remove 3 20cm by 30cm square .water and covered with a fabric sample. The whole assembly is then weighed and reweighed after a certain elapse of time. The water vapour permeability of the fabric is the loss in weight of water in the cup, expressed in g/m2/day. Since the water vapour permeability is .
Any material which is permeable to air is also likely to be permeable to moisture vapor. Hence, the air permeability is in general closely related to moisture–vapor permeability and the liquid moisture transmission. Fabrics made from cotton or wool undergoes swelling upon absorption of water vapor from the atmosphere. This would close off the .Water Vapor Permeability Test is used to determine the rate of water vapor transmission for fabric, coating fabric, composite, apparel, industrial fabrics, etc. Endowed with specialized air flue to control the wind speed, temperature and humidity; and chamber size 500×500×500mm, Normally our machine only euipped with one set cups.As for ASTM .Water Vapour Permeability Tester is used to determine the resistance of textiles and textile composites to water vapor penetration under room condition.RF4319 water vapor permeability tester, consists of 8 test cups with water reservoirs and a precision drive system. . ( especially sport wear fabrics) Testing Standards . BS7209, BS3424-34 . A water vapor permeability test is necessary for determining the water resistance of fabrics. Designers and manufacturers must know how much fabric is breathable and maintain product quality. . Other standards are used for measuring the moisture permeability of fabrics. The following list shows these standards. ISO 2528; JIS L1099 A and .
