WATER VAPOUR PERMEABILITY CUP (FOR TEXTILE)
Overview of WATER VAPOUR PERMEABILITY CUP (FOR TEXTILE)
This tester is used to evaluate the permeability of textile products according to the calcium chloride method or the water method.
The permeability will be measured by the mass of vapour that went through a unit area of membrane under prescript temperature and moisture.
