Teflon clothing membrane has many functions, including isolating germs, harmful ultra-fine dust, acid and alkaline solutions, etc. It can effectively ensure The lives and jobs of those involved are kept safe while the environment is kept clean.
With the popularity of outdoor sports, more and more people wear jackets in winter. Jackets were originally: functional clothing designed to adapt to extreme outdoor weather. The three most important functions are: windproof, rainproof and breathable. Many friends will ask: Is it waterproof and breathable? Isn’t this a contradiction? Just like a plastic bag, it is waterproof but not breathable. With the development of science and technology, it is now possible to achieve the above functions by attaching different coatings or composite waterproof membranes to the back of the fabric. Currently, the generally recognized waterproof layers are divided into four generations.
First generation: In order to achieve waterproof and windproof effects at the earliest, waterproof glue was just brushed on the fabric to achieve waterproof purposes. This material and process are made The product can withstand a certain amount of water pressure, but its air permeability is relatively poor. And due to the instability of the coating process, the coating is easy to peel off. The waterproof effect is unstable.
Second generation: PU film, which is a material with good water pressure resistance. The product fabric is combined with it to achieve waterproof stability. Better, its high-end products may have some moisture permeability function, but the effect is not ideal.
The third generation: TPU film, developed on the basis of PU film, is better than PU film in terms of air permeability, moisture permeability, and water pressure resistance. A waterproof and breathable membrane that replaces PU membrane.
Fourth generation: Teflon garment membrane is the latest generation of waterproof and breathable materials, currently used by many manufacturers. The main principle of Teflon clothing membrane is to stretch polytetrafluoroethylene to make micropores appear, and the diameter of the micropores must be controlled to be about 700 times that of water molecules and 20,000 times that of water droplets. 1. There are approximately 9 billion micropores in each square centimeter of Teflon clothing membrane. Water droplets cannot pass through such micropores, but sweat can pass through the micropores in the form of molecules. The holes are eliminated, thus achieving the purpose of waterproofing and breathability. Interested parties can enter the store for consultation and purchase!
