This Liquid resistance tester is to measure the indices of penetration, absorption and repellency for protective clothing materials against liquid chemicals, mainly chemicals of low volatility. By checking the quality change of chemicals which move through the tested protective clothing material at certain outflow rate, the repellency index can be calculated.
For the test a transparent film and filter paper will be first be placed in the channel. Then, the sample fabric will be placed in a way that ensures that all surfaces are making contact and wrinkle-free. A beaker—which should be weighed beforehand—is placed at the end of the channel to gather the liquid the runs through the surface of the fabric.
