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

DuPont Teflon (Teflon), friends who trust the outdoor circle are all 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. Many outdoor work clothes, 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 fabric of these products adopts The Teflon finishing agent of DuPont Company in the United States has been treated with water repellency (three-proof). This hangtag is authorized and provided by DuPont Company to verify the authenticity. So how can Teflon achieve certain water blocking performance? What is the process of Teflon treatment of workwear fabrics? Today, I will give you a brief introduction based on some information I have collected and some knowledge about DuPont Teflon finishing in fabric 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 fabric industry for the so-called “three-proof” finishing of fabrics (water-repellent, oil-proof, and stain removal). 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 cleaning frequency
Excellent water washing resistance and dry cleaning resistance	After the cloth has been washed many 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 extraordinary storage measures required

What are the types of protective finishing 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 fabric industry and garment manufacturers. It plays an indispensable role in the fabric 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…It shows the in-depth progress of Teflon fabric protective technology treatment in Asia, and also shows that the market demand driven by the cooperation between Teflon fabric protective functional fabrics and excellent domestic retailers has been fully recognized. This time, the “Teflon overcomes stains and enjoys worry-free cleanliness” work wear show has received strong support from work wear 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)

Multifunctional 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 avoid contamination during the cleaning process, making clothes “long-lasting”. . Multifunctional, easy-to-remove Teflon is different from other stain-removing products in that it can reduce fading caused by frequent cleaning, and its soft texture is suitable 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 clothes from absorbing the dirt. The highly durable and powerful decontamination 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 and easy-to-remove stains with superb decontamination technology. It integrates 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 making khaki For clothing, knitted tops, work clothes, school uniforms, children’s clothing, outerwear, linen products and washable household fabrics, the decontamination and anti-contamination measures can be described as “flawless”.

The water-blocking principle of Teflon treatment is that the fabrics prepared and finished with Teflon finishing agent have a lower surface energy. Due to the low surface energy of the material and its non-stick characteristics, the low surface energy fabric has the above-mentioned ” The characteristics and effectiveness of “Three Defenses”. Teflon makes use of the fluorine-containing active agent in the material (the production process of organic fluorine fabric finishing agent 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, Use environment, we don’t need to panic) ingredients to reduce the surface energy of the fabric, so that the fabric can achieve a certain water-blocking function. As for the complex surface energy theory, let it be discussed, we will not discuss it.

The well-known silicone coating water-blocking treatment for cotton 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 work clothes and shoes. .

Fabrics finished with Teflon do not have permanent water-repellent resistance, but gradually lose the so-called “three-proof” effect as the number of cleanings increases. It is understood that the “three-proof” effect will generally disappear after 4 cleanings. There is some decrease. This is because after the fabric is soaked and scrubbed in water, the Teflon component contained in it will be gradually lost. Coupled with the action of microorganisms in nature, the water-repellent group molecules on the surface of the fabric will be rearranged, making the surface of the fabric more efficient. will gradually rise. As 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 not 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 for “three-proof” finishing of fabrics must be authorized by DuPont. After the products pass the test, they will be issued a special Teflon logo tag. According to the export Depending on the country and 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 of the fabric costs about the commercial price of a piece of workwear. The proportion can be said to be very low.
