What is Teflon fabric and three-proof fabric?
The three-proof fabrics we often talk about usually refer to: water-blocking fabrics, oil-proof fabrics, and stain-repellent fabrics. Water-repellent fabrics in English are: “Water Repellent Fabric”, and oil-proof fabrics in English are: “Oil Repellent Fabric” ( We generally refer to nylon water-repellent and breathable fabrics, polyester water-repellent and breathable fabrics, nylon water-repellent and breathable fabrics, polyester water-repellent and breathable fabrics, water-repellent and breathable fabrics, etc.)
When making three-proof fabric products, we usually use DuPont Teflon three-proof additive products. Below we will introduce Teflon products in detail.
Nylon water-repellent and breathable fabric, polyester water-repellent and breathable fabric, Teflon product detailed introduction:
Teflon high-performance special coating is a fluorine coating with polytetrafluoroethylene as the base resin. The English name is Teflon. Because of the pronunciation, it is also commonly called Teflon, Teflon, Teflon, and Teflon. Long and so on (all are transliterations of Teflon). Teflon (Teflon) coating is a unique high-performance coating that combines heat resistance, chemical inertness, excellent insulation stability and low friction. It has comprehensive advantages that other coatings cannot compete with. It is sensitive in application. Its durability allows it to be used on almost all shapes and sizes of products.
Teflon water-repellent and breathable fabrics are divided into several basic types: PTFE, FEP, PFA, and ETFE:
Teflon water-blocking breathable fabric PTFE: Polytetrafluoroethylene (polytetrafluoroethylene) non-stick coating can be used continuously at 260℃, has a high use temperature of 290-300℃, extremely low friction coefficient, good resistance Grindability and excellent chemical stability.
Teflon water-blocking breathable fabric FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a non-porous film. It has excellent chemical stability, excellent non-stick properties, and a high use temperature of 200℃.
Teflon water-blocking breathable fabric PFA: PFA (perfluoroalkylate) non-stick coating, like FEP, melts and flows during baking to form a non-porous film. The advantage of PFA is that it has a higher continuous use temperature of 260°C and stronger toughness, which is very suitable for use in anti-stick and chemical resistance fields under high temperature conditions.
Teflon water-blocking breathable fabric ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene, a tough fluoropolymer that forms a highly durable PU coating with excellent chemical resistance and Can work continuously at 150℃.
Teflon nylon water-blocking and breathable fabrics and polyester water-blocking and breathable fabrics have the following characteristics:
1) Non-stickiness: Nylon water-repellent and breathable fabric and polyester water-resistant and breathable fabric are bonded with Teflon coating. The very thin film also shows good water-blocking, oil-proof, and stain-repellent functional fabrics.
2) Heat resistance: Nylon water-blocking and breathable fabrics and polyester water-blocking and breathable fabrics have excellent heat resistance and low temperature resistance after being coated with Teflon PU coating. It can withstand high temperatures up to 300°C in a short period of time, and can generally be used continuously between 240°C and 260°C. It has significant thermal stability. It can work at freezing temperatures without brittleness, and without melting at high temperatures.
3) Sliding properties: Nylon water-repellent and breathable fabrics and polyester water-repellent and breathable fabrics with Teflon PU coating have a lower friction coefficient. The friction coefficient changes when the load slides, but the value is only between 0.05-0.15.
4) Moisture resistance: The surface of the coating film of Teflon, nylon, water-blocking and breathable fabrics and polyester water-blocking and breathable fabrics does not stick to water and oil, and it is not easy to stick to solutions during production operations. If there is a small amount of dirt, it can be removed by simply wiping it. Short downtime, saving man-hours and improving work efficiency.
5) Wear resistance: Nylon water-repellent and breathable fabrics and polyester water-repellent and breathable fabrics have excellent wear resistance under high loads. Under a certain load, it has the dual advantages of wear resistance and non-adhesion.
6) Corrosion resistance: Teflon, nylon, water-repellent and breathable fabrics and polyester water-repellent and breathable fabrics are almost not corroded by chemicals and can protect parts from any kind of chemical corrosion.
Teflon products include nylon water-repellent and breathable fabrics and polyester water-repellent and breathable fabrics. They are widely used in industries that are resistant to high temperatures and require viscosity, such as special work clothes and work clothes for working in unusual environments.
Teflon fabric, DuPont Teflon three-proof fabric from the United States. The protective technology treatment uses fluorine-containing compound technology to form a molecular barrier around each fiber. It reduces the critical surface tension of the fiber, making it effective in resisting water. and oily liquid stains. Powerful decontamination products require that fabrics can still be effectively decontaminated after 30 washes, and the functional performance can be sustained up to 50 washes. Using advanced nanotechnology, Teflon products make nylon water-blocking and breathable fabrics and polyester water-blocking and breathable fabrics not only Powerfully removes stains and feels softer and more comfortable.
Teflon three-proof fabric refers to general fabrics that have excellent water-blocking functions, oil-proof fabrics, and stain-repelling functions after being treated with DuPont Teflon three-proof additives. They are commonly known as “three-proof fabrics.” Keep the fabric clean and tidy. According to the washing resistance, it can be divided into general Teflon (Teflon) and super strong Teflon (Hi-Teflon). Compared with ordinary fabrics, this fabric not only has a more beautiful appearance, but also has excellent anti-oil, water-splashing, and anti-stain effects like lotus leaves, which can effectively prevent oil, water, and stains from penetrating into the inner layer of the fiber. keep cloth�Keeps it dry and clean for a long time. Super strong Teflon can still reach 90 points after being washed 20 times, and can reach 100 points before washing. This fabric can be widely used in general garment fabrics, jacket fabrics, casual wear fabrics, down jacket fabrics, sleeping bag fabrics, etc.
The fabric has the properties of oil repellent, water repellent and water pressure resistance. That is, after the three-proof finishing of the fabric, the surface properties of the fabric are changed, turning the hydrophilicity into hydrophobicity. Water droplets can roll on the fabric but cannot wet it. Water-blocking and breathable fabrics are two opposite but closely related important properties in the wearing performance. Water resistance refers to preventing water droplets from entering the inside of the fabric from the outside, while breathability refers to sweat and moisture escaping from the inside of the fabric through the fabric. Nylon water-blocking and breathable fabrics and polyester water-blocking and breathable fabrics refer to fabrics that can not only prevent rain and wind, but also perspire, breathable, and are comfortable to wear. During the wearing process, water does not penetrate the fabric under a certain pressure, and the sweat emitted by the human body It can pass through fabrics or be transmitted to the outside world in the form of water vapor, instead of condensation and accumulation between fabrics on the surface of the human body, keeping the wearer dry and warm. The fabric feels soft, environmentally friendly and healthy, not easy to change color, breathable and impermeable. In addition, its strong fastness, color and style are almost the same as the original fabric, making it comfortable to wear. The main features are:
1. It can give good water-repellent and oil-repellent effects to synthetic fibers such as nylon water-blocking breathable fabrics and polyester water-blocking breathable fabrics, natural fibers such as cotton, polyester/cotton, and their blended chemical fiber fabrics.
2. Can be used together with other fabric treatment agents, such as antibacterial fabrics, fireproof fabrics, and antistatic finishing fabrics.
3. It has little impact on the rubbing fastness and washing fastness of dyed fabrics, and has almost no impact on the color finish.
Teflon nylon water-blocking and breathable fabrics and polyester water-blocking and breathable fabrics have the following characteristics: Various types of protective clothing made of Teflon three-proof fabric are suitable for workers who frequently come into contact with oil and water media as labor protective clothing. The protective clothing does not soak when exposed to oil and does not seep when exposed to water. It overcomes the contradiction between breathability and oil and water repellency, has good air permeability and air permeability, and is comfortable to wear.
