What is the difference between PTFE composite fabrics and PU and TPU fabrics?

Materials For Removable Insulated Jackets waterproof and breathable function is to compound a layer of microporous film on the outer fabric of the garment. The micropores are smaller than water droplet molecules and larger than gas molecules, so Porous PTFE Fabric can volatilize its own sweat while blocking rainwater.Ptfe Insulation Jacketing Fabric is characterized by excellent stability, and its performance is not easy to change even at low temperatures, so it is often used in various harsh environments.

2. PU or TPU coated fabric

PU and TPU fabrics are mostly coated with a waterproof and breathable layer under the outer fabric. The breathability of this fabric will decrease at low temperatures, but it is cheaper and more durable and washable than PTFE.

Therefore, we often see that some big brands will use PTFE composite fabrics to make professional models, and use PU and TPU fabrics to make some cheap low-altitude sportswear.
At present, the PTFE clothing film series independently developed by Youkefa is the core raw material of high-end jackets. It has excellent waterproof performance and can effectively block rainwater; good air permeability, sweat can be effectively removed, and human comfort is maintained; good wear resistance and washing resistance, etc. characteristic!
