Testing standards and requirements for DuPont three-proof Teflon finishing agent

There are currently many testing standards for the three-proof effect of fabrics, including domestic standards and international standards, American standards and European standards. DuPont three-proof Teflon finishing agent is developed and produced by DuPont in the United States. The testing of three-proof protection performance is also required according to American standards and international standards. Let’s briefly introduce DuPont Teflon three-proof Water-repellent, oil-proof, and decontamination testing standards for finishing agents. This article comes from the chemical industry website.

1. Testing standards for the water-blocking performance of DuPont three-proof: The implementation standard is AATCC22-1996/ISO4920. Cleaning requirements: 10 times of general household cleaning. Initial water-repellent performance requirements: more than 90 points. After 10 times of washing, it is required to reach 80 points. In fact, the water-blocking performance of DuPont Teflon can generally reach 100 points initially, and can reach 90 points after being washed 10 times.

2. Testing standards for the oil-proof function of DuPont Teflon three-proof finishing agent: the implementation standard is AATCC118-1997/ISO14419, cleaning requirements: 10 times of general household cleaning, initial oil-proof function requirements: level 5 or above, after 10 times of washing It is required to reach level 3 or above. In fact, the oil-proof function of DuPont Teflon can generally reach level 5 initially, and can reach level 4 after being washed 10 times.

3. DuPont Teflon three-proof finishing agent water-resistant stain performance testing standard: The implementation standard is AATCC193-2004. Cleaning requirements: 10 times of general household cleaning. Initial water-resistant stain functional requirements: Level 6 or above, required after 10 times of washing. Reach level 5 or above. In fact, the water-repellent stain resistance of DuPont Teflon can generally reach level 6 or above initially, and it can reach level 5 or above after 10 times of washing.
