The outdoor fabric industry is customarily called water pressure resistance, and the unit is expressed in mmH2O, which means that the unit area bears the strength of water pressure. Under standard laboratory conditions, the fabric is subjected to the pressure of spraying distilled water up, and the maximum water pressure is recorded, such as water pressure 5000mmH2O. That is, the unit area can withstand a maximum pressure of 5m without leakage.
Commonly used test standards: American standard AATCC 127; Japanese standard JIS L1092B; European standard: IS0 811;
1. Test before washing: Domestic outdoor brands generally test the water pressure resistance value before washing, but do not measure the value after washing. The water pressure resistance value drops greatly after washing several times, which may drop by about 1000-3000mmH2O;
2. Test after washing: Well-known outdoor brands in foreign countries usually test the water pressure after 5 times of washing, and even use the method of measuring the water pressure after 20 times of washing. Due to the test after multiple washings, the water pressure value drops very much. The test method is that any coating factory or lamination factory must use better materials for processing. For example, the water pressure resistance of the coated fabric must reach 5000mmH2O after 5 washings, then at least 7-8000mmH2O before washing; of course, this requirement will Lead to higher prices!
