Coffee YARN uses two main selected components, "coffee" and "mica", to which a variety of special chemical materials are added, and then polyester, nylon or viscose are used as carriers, which are spun into fibres using special processes.

The composite construction means that the coffee residue is mixed into the fibre and filament. The coffee fibre and filament provide odour control and moisture absorption.
The mica has a layered structure and is transparent and colourless. Mica has a melting point of 1300℃, so its physical properties are completely unchanged at the high temperature of 550℃. The thermal conductivity rate W/m℃ of mica is I.4 (at 20℃), almost 5 times that of normal polyester (0.3), making it an optimal thermal conductor material with excellent cooling/heat transfer properties.

The nano mica's surface is electrically charged,  its hydration is very high, has excellent water absorption effect, so it can promote water absorption effect and can promote cooling effect.

With above mentioned features, Mica has a dual effect of high heat conduction and water absorption, which makes nano mica an optimal new generation cooling material.

After combining coffee and mica, using a base of polyester, nylon or viscose, the resulting fibre is a multifunctional material.

Our insole experts use this new technologies in our insoles. The new Dazhou Coffee Yarn insoles can provide functions with the ice cool touch, odor control, UV protection and moisture management at the same time.

The new Coffee Yarn insoles will be soon available on our websites. Feel free to contact us!
