Characteristics of PTFE Garment Membrane

With the development of technology, more and more special fabrics are produced and invented. The PTFE garment membrane is made of PTFE as raw material and adopts a special process to form a PTFE composite fabric. The PTFE membrane has the special effects of waterproof and moisture permeability, windproof and warmth. PTFE clothing film is widely used in sportswear, cold-proof clothing, military, fire, public security, medical, biochemical and other special clothing, shoes, hats, gloves, sleeping bags, tents, etc. Next, I will introduce the characteristics of PTFE garment membrane.

Ⅰ. Waterproof performance of PTFE membrane

Waterproof means that the water on the outside of the fabric will not penetrate the fabric and soak into the inside. Wearing the fabric, even if you are standing in a storm and sitting on a wet surface, people will not feel damp. The reason why the PTFE membrane fabric garment has such a magical function is mainly because the pore diameter of the PTFE membrane of the main body of the fabric is 1/40000 of the diameter of the water droplet, so even the smallest raindrop cannot pass through.

Ⅱ. Moisture permeability of PTFE membrane

The porosity of the PTFE membrane is as high as 80%, and the pore size is 700 times larger than that of water vapor molecules, and water vapor molecules can pass freely.

Ⅲ. Windproof performance of PTFE membrane

During the stretching process of the PTFE film, a microporous structure connecting nodes and countless microfibers is formed, and pores are formed between the microfibers, and the pores are connected to each other to form a unique network structure. The wind cannot pass directly, and it will change direction and fold back when it encounters barriers. The windproof membrane can effectively prevent the penetration of air, so it has excellent windproof performance.

Ⅳ. Thermal performance of PTFE membrane

PTFE film has excellent moisture permeability, which can transport the vapor discharged from the human body to the outside of the microclimate in time, prevent water vapor from condensing into liquid water, and reduce the possibility of water conduction heat. Although the surface of the film is dense with a large number of micropores, the wind cannot penetrate, effectively preventing air convection. Tests show that in a strong wind of 25m/s, the thermal insulation effect of PTFE composite fabric with PTFE membrane is 30-40% higher than that of traditional down jackets.
