What is the basis for the testing standards of DuPont three-proof Teflon finishing agent?
There are many testing standards for the three-proof effect of fabrics , including domestic standards and international standards. There are 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 protective performance is also based on American standards and national standards. Let’s briefly introduce DuPont three-proof Teflon. Water-blocking, oil-proof, and decontamination testing standards for three-proof finishing agents.
Testing standards for the water-blocking performance of DuPont three-proof Teflon finishing agent: The implementation standard is AATCC22-1996/ISO4920. Cleaning requirements: 10 times of general household cleaning. Initial water-blocking performance requirements: 90 points or more. The requirements are met after 10 times of washing. 80 points. In fact, the water-blocking performance of DuPont three-proof Teflon can generally reach 100 points initially, and can reach 90 points after being washed 10 times.
Testing standards for the oil-proof function of DuPont three-proof Teflon 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, and the requirements are met after 10 times of washing Level 3 or above. In fact, the oil-proof function of DuPont three-proof Teflon can generally reach level 5 initially, and can reach level 4 after being washed 10 times.
DuPont three-proof Teflon finishing agent water-repellent stain performance testing standard: the implementation standard is AATCC193-2004, cleaning requirements: general household cleaning 10 times, initial water-repellent stain functional requirements: 6 or above, after 10 times of washing, the requirement is 5 level and above. In fact, the water-resistant stain resistance function of DuPont three-proof Teflon can generally reach level 6 or above initially, and it can reach level 5 or above after 10 times of washing.
