The moisture permeability of the fabric can be measured, especially for medical dressings, the moisture permeability of adhesive or gauze is very important.If the moisture permeability is not enough, the air permeability is not strong enough.Skin can't breathe properly If there is a wound, long periods of airlessness can lead to skin decay.

Main use of fabric moisture permeability tester

M029 Fabric Water Vapor Transmission Tester USES the moisture permeability cup method to measure the ability of water vapor to penetrate the fabric.The instrument is used to measure the moisture permeability of all kinds of fabrics (including wet-permeable coated fabrics) as well as cotton wool, space cotton and other fabrics used in clothing nonwovens.The moisture permeability can reflect the performance of clothing sweat and steam, and is one of the important indexes to evaluate the comfort and hygiene of clothing.
