What is the waterproof performance of DuPont three-proof
Recently, many customers have inquired about the water-blocking performance of DuPont three-proof Teflon, saying that my fabric has very high requirements for water-blocking performance and needs to reach more than 90 points. Is it only DuPont Teflon that can do it? Wait for similar questions.
It is true that DuPont three-proof Teflon has excellent water-blocking performance, outstanding rain-proof effect and water-soluble dirt repellency. Moreover, DuPont three-proof has long-lasting water-blocking and water-repellent properties, and has excellent water-wash resistance and excellent dry-cleaning resistance. The AATCC22-1996 standard is used to test the water repellency of DuPont three-proof Teflon fabric. The initial water resistance can reach more than 90 points, and the water resistance can reach more than 80 points after 10 times of washing. The initial water resistance of fabrics treated with powerful Teflon can reach more than 90 points. 100 points, the average household can still reach more than 70 points after 30 times of cleaning; the AATCC193-2004 standard is used to test the water-soluble stain resistance performance of Teflon fabrics. It can reach level 6 initially and can reach level 6 after 10 times of washing in the drying test. Level 5 and above.
Judging from the above test data: DuPont three-proof Teflon-treated fabrics indeed have excellent water-blocking properties. Can we say that the water blocking effect of DuPont Teflon is good? Actually, that’s not entirely the case. At present, some imported brands of strong water-blocking agents on the market can also achieve such water-blocking performance. Some water-blocking agents even have better initial water-repellent properties than those treated with Teflon under the same dosage and process conditions as Teflon. The fabric is strong. Why is this? Because only when the amount of Teflon reaches a certain amount, the excellent water-blocking performance can be reflected. Relatively speaking, the solid content of DuPont three-proof Teflon finishing agent is lower than that of general strong water-blocking agents. , but the DuPont tri-proof Tesolon finishing agent contains synergistic ingredients and has a relatively high fluorine content, so the biggest feature of Teflon-treated fabrics is its water-blocking performance and super washability. General strong water-blocking agents The washing resistance is not very good, and cross-linking agents, reinforcing agents, etc. need to be added during post-finishing to improve the washing resistance of the fabric. Even so, their durability is not the same as that of Teflon. language. In addition, DuPont’s three-proof Teflon finishing agent also has good ability to repel water-soluble stains and oil-based stains. General strong water-repellent agents are very weak in this regard.
Generally speaking, DuPont three-proof Teflon is a multi-functional three-proof finishing agent. It also has the functions of blocking water, repelling water-soluble stains, preventing oil, preventing oily stains, preventing dry stains, and preventing dust. What is emphasized is a comprehensive functional effect. But only in terms of water-blocking performance, it can be said that DuPont three-proof Teflon is not good. The initial water-blocking performance of some strong water-blocking agents is comparable to that of Teflon.
If the customer only pays attention to the initial strong water-repellent performance, and there are many products to choose from, you can choose a cost-effective water-blocking agent that suits your needs rather than DuPont Teflon, which can effectively control the product’s properties. cost. Of course, if you require durable and strong water-blocking performance, then choose DuPont Teflon. Chemical Industry develops optimal post-finishing solutions for customers. Save time and cost for customers and make their fabrics more competitive in the market! Consultation hotline: 400-0909-770 (no long-distance charges)
