Fabric Water Vapour Permeability Testing Apparatus - China

Fabric water vapour permeability testing apparatus is for assessment of the water vapour permeability ability of fabrics by moisture permeable cup moisture absorption method.

The instrument is used to determine moisture (steam) permeability of various types of fabrics (including moisture-permeable coated fabrics) as well as cotton and space cotton for non-woven clothing.

Moisture permeability can reflect the perspiration and steam permeability of clothing, one of the important indicators to identify the comfort and hygiene of clothing.

Application The instrument is used to determine moisture (steam) permeability of various types of fabrics (including moisture-permeable coated fabrics) as well as cotton and space cotton for non-woven clothing.
