How It Works
NanoGLIDE® allows air to move freely through the PTFE pores creating a massive surface area for vapor and water to pass through minimizing wetting out.
Hydroscopic Yarn
PTFE NanoGLIDE® is a hydroscopic yarn meaning it is a porous material much like soil or snow layers. The PTFE porous particles create a massive surface area on the yarn and thus the fabric material.
The particles are small enough to be distributed in great numbers. These hydrophobic PTFE particles help resist wetting out without affecting air permeability. PTFE improves abrasion properties that can lead to lower fabric weights from the loft created by the PTFE attached to the yarn. These PTFE particles create a lower co-efficient surface area on the yarn when wet or dry. The yarn can be both hydrophobic and hydrophilic at the same time allowing air to move freely through the PTFE pores creating a surface area for vapor and water to pass through minimizing wetting out. Though the PTFE particle is mostly being used to keep the body cool, it can help keep the body warm too. It behaves differently based on the presence or absence of humidity. If there is a lot of relative humidity, it uses the energy to improve evaporation. If it's dry, that means your body is cold, and it returns that energy to the skin because PTFE is known for its insulation properties.
Drying-2 Important Points
- Transfer of Heat
- Movement of water and water vapor through the textile
The Solution - PTFE NanoGLIDE®
The naked body produces varying amounts of friction in different regions of the body (arm/torso, inter-thigh/, toe on toe, heel to sock, etc.).
This friction produces heat & sweat, particularly on the chest, underarms, feet, and back. The clothed body produces additional friction in ALL areas of fabric/skin contact and magnifies friction in all these areas.
Think of it this way. On average a 6-foot male running 6 miles/10 km will take 820 strides to jog 1km and 1,300 strides to cover a mile. If a man does this without a shirt on, the frictional forces will be equal to the CoF of skin on skin with no frictional forces accruing to any areas not affected by skin-on-skin interaction (chest, beck, stomach, shoulders). And running naked when the weather is warm feels great until the saline and enzymes build up and you begin to generate pit-rash. Now add a shirt or the foot striking the ground with a sock on and the issues are amplified during your physical activity.
