What tests should be done on oil and water repellent fabrics
Classification:
Oil and water repellent fabric
Oil and water repellent fabric What test to do?
1.
Flatness: AATCC124, the washing method test is the same as the shrinkage test. Generally, each customer corresponds to it. The main reason is that the washing water temperature and washing times are different;
2. Waterproof performance test:
Generally measure an initial value and test results after N times of water washing;
WaterproofTest: Spray Method: AATCC22 and ISO4920 are the same;
Water dripping method: directly drop prepared water onto the surface of the cloth to see the diffusion and penetration of the water droplets;
3.Oil-proofPerformance test (AATCC118): directly use oil droplets of 0.5MM size, Diffusion after 30 seconds;
4. Formaldehyde content test: Under normal circumstances, the formaldehyde content of conventional finishing is less than 20PPM, so physical testing is generally not tested. Only those finished with resin will be tested for formaldehyde content. Divided into AATCC112, JIS
There are two tests, L1041, and the most commonly used JISL1041 test.
Free Formaldehyde: FREE FOR MALDEHYDE CONTENT
By soaking the fabric in water, and after designated temperature, time, and static treatment, formaldehyde is hydrolyzed and dissolved in the water.
Formaldehyde release: The release method is used to measure the formaldehyde released in the air after the fabric is exposed to specified temperature, time, and static treatment. Then dissolve in water.
Generally, the formaldehyde released is higher than the free formaldehyde.
5. PH value test: Normally, the fabric is dissolved in water to measure the PH value of the water. Therefore, sometimes due to unclear alkali removal by mercerization in the front process, it is always difficult to adjust the alkali in the back process by adding acid. Adding too much acid will lead to neutralization of acid and alkali. Reduce strength.
