What is DuPont three-proof Teflon (Teflon) finishing?

DuPont Teflon (Teflon), I believe friends in the outdoor circle are familiar with this term. DuPont Teflon has a wide range of applications. Here we mainly talk about the so-called “Teflon water repellent” treatment that we often come into contact with. Everyone has seen it. Nowadays, many outdoor clothing, sleeping bags and other product descriptions will have words such as “surface DuPont Teflon treatment”, and a Teflon hangtag is attached to the product (see teflon hangtag display). This hangtag shows that the fabrics of these products are made of American DuPont’s Teflon finishing agent has been treated to be water-repellent (three-proof). This hangtag is authorized and provided by DuPont to verify the authenticity. So how can Teflon achieve a certain waterproof performance? What is the process of Teflon treatment of clothing fabrics? Today, I will give you a brief introduction based on some information I have collected and some knowledge about DuPont Teflon finishing learned in textile dyeing and finishing companies.

First, let’s take a brief look at Teflon. Teflon is a chemical agent developed by DuPont in the United States. It is a hydrocarbon resin that contains organic fluorine substances. Its chemical properties are relatively stable and it has high and low temperature resistance. Strong, it is currently mainly used in the textile industry for the so-called “three-proof” finishing of fabrics (waterproof, oil-proof, anti-fouling). For the description of DuPont’s three-proof Teflon product characteristics, please refer to the table below:

Features	Benefits
Outstanding oil repellency	Excellent protective effect, preventing oily stains from penetrating into the fabric. Fabrics maintain a cleaner appearance longer, resulting in fewer necessary washes.
Excellent water repellency	Excellent anti-rain effect and water-soluble dirt repellency.
Outstanding dry stain resistance	Dust and dry stains are easily shaken off or brushed away, keeping fabrics clean and reducing washing frequency
Excellent water washing resistance and dry cleaning resistance	After the cloth has been washed several times and then ironed or similar heat treated, it can regain its high-efficiency protective properties.
Does not affect breathability	Comfortable to wear
Good operating characteristics	It is not easy to stick to the roller, so production can be carried out smoothly
Contains no volatile organic solvents/no flash point	No special storage measures are required

What are the protective finishing types of DuPont Teflon fabric?

DuPont Teflon fabric protection technology treatment combines the two major advantages of easy care and resistance to all stains on daily clothing. This series is widely used and can meet the different needs of the textile industry and garment manufacturers. It plays an indispensable role in the textile industry. A missing role. On October 26, the Outsmart Partner Awards (Outsmart Partner Awards) presented by INVISTA at the “Outsmart Stains, Worry-Free” conference not only reflected Teflon’sThe in-depth development of fabric protection technology treatment in Asia also shows that the market demand for Teflon fabric protection functional fabrics driven by cooperation with outstanding domestic retailers has been fully recognized. This “Teflon outsmarts stains and enjoys worry-free cleansing” clothing show has received strong support from clothing brands such as Jiayu, Egger, and Kappa.

At the award ceremony, Mr. Huw Williams, President of Business Development of INVISTA’s Apparel Division, said: “In addition to quality, appearance and feel, fabric functionality has also become the primary factor for consumers to choose products, and the requirements are getting higher and higher, which has prompted the Asian market to Demand is growing rapidly. This is undoubtedly the result of the sincere cooperation between our brand alliances, and the Outsmart Partner Awards are designed to praise and motivate alliance members.”

It is reported that the new members of DuPont’s Teflon fabric product series include:

1. Multifunctional, easy-to-remove Teflon (Ultra Release Teflon)

Multi-functional and easy-to-remove Teflon has made breakthroughs in comfort, functionality and stain management. It can deeply remove common stains such as grass clippings and dust, and can also prevent dirt from being stained during the washing process, making clothes “long-lasting”. . Versatile, stain-removing Teflon differs from other stain-removing products in that it reduces fading caused by frequent washing and is soft enough for casual wear applications.

2. Powerful and easy-to-remove Teflon (High Performance Release Teflon)

Powerful and easy-to-remove Teflon is the nemesis of pollutants that invade the inner layer of fabrics. Whether it is oil stains, dirt, or sweat stains on the collar, as long as it encounters it, it will be removed without leaving a trace. This fabric protection technology treatment is suitable for products that are frequently washed, such as underwear, uniforms, bed sheets and tablecloths.

3. High Performance Repel Teflon

A good way to effectively deal with serious stains is to prevent the clothing from absorbing the dirt. The highly durable and powerful anti-fouling Teflon can withstand 50 washes in tests, far exceeding the standard minimum of 30 times. It is mainly suitable for clothes that can still remain new after multiple washes.

4. Advanced Dual Action Teflon

Advanced double-effect Teflon combines powerful, easy-to-remove, and anti-fouling superb technologies, integrating the functions of isolating and removing stains. It not only prevents the inhalation of water-based and oil-based stains, but also easily cleans invading stains. It is an ideal choice for manufacturing khaki Clothing, knitted tops, work clothes, school uniforms, children’s clothing, outerwear, linen products and washable household textiles, the anti-fouling and anti-fouling measures can be described as “flawless”.

The waterproofing principle of Teflon treatment is that textiles prepared and finished with Teflon finishing agents have lower surface energy. Due to the low surface energy of the material and its non-stick characteristics, low surface energy fabrics have the above-mentioned “three defenses” features and performance. Teflon makes use of fluorine-containing active agents in the material (the production process of organic fluorine fabric finishing agents requires the use of ammonium perfluorooctanoate, which is currently being questioned about its safety and has not yet been concluded. This is a surfactant. In view of the use of outdoor equipment Environment, we all don’t need to panic) ingredients to reduce the surface energy of textiles so that the fabrics can achieve a certain waterproof function. As for the complex surface energy theory, let it be discussed, we will not discuss it.

The well-known silicone coating waterproof treatment of tents also uses silicone materials to reduce the surface of the fabric to achieve a water-repellent effect. This is also the principle of the water-repellent agent used by some friends to maintain clothing and shoes.

Fabrics finished with Teflon are not permanently water-repellent, but gradually lose the so-called “three-proof” effect as the number of washes increases. It is understood that the “three-proof” effect will generally appear after 4 washes. This is because the Teflon component contained in the fabric will be gradually lost after being soaked and scrubbed in water. Coupled with the action of microorganisms in nature, the water-repellent group molecules on the surface of the fabric will be rearranged, causing the surface of the fabric to Gradually rising, the surface energy of the fabric increases, the “three defenses” effect decreases, and the fabric loses the so-called “three defenses” effectiveness. These characteristics tell us that we should try not to use soaking and scrubbing to clean fabrics that have been treated with water-repellent treatment.

Teflon is a registered trademark of DuPont in the United States. Currently, domestic dyeing and finishing companies that use Teflon finishing agents to “three-proof” fabrics must be authorized by DuPont. After the products pass the test, they will be issued a special Teflon logo tag. According to the exporting country and Depending on the region, there are generally two types of hangtags with Shikoku characters and hangtags with Six Kingdoms characters. As far as I know, the Teflon “three-proof” finishing process and technology are not complicated. After the three main finishing processes of preliminary finishing, padding, and drying, the Teflon finishing cost of the fabric accounts for the proportion of the market price of a piece of clothing. It can be said to be very low.
