What makes our felt so valuable
Why is it water and dirt repellent?
Thanks to the lanolin contained in the felt (also known as wool wax or wool grease), water droplets bead up on the surface before they can soak in. They can simply be shaken or dabbed off. The natural layer of grease also makes it harder for dirt to penetrate the fibres and soil the felt. Think of it as a kind of lotus effect.
Why is it moisture-regulating and gentle on the skin?
The felt is permeable to water vapour and can transport moisture along the wool fibre. It can absorb up to 50% of its own weight in water vapour, store it and then gradually release it back into the environment – without losing its insulating properties. It is soft, feels pleasant to the touch and, as a natural material, does not irritate the skin.
Why does our felt protect?
Felt protects against the wear and tear of everyday life: pressure, drops, impacts, scratches, moisture. Wool felt consists of matted fibres with pockets of air in between. On impact, the fibres compress, the air spreads the energy across the surface, and the felt springs back. The wool fibre yields – and straightens up again. Naturally, time and time again. And because the wool fibre is softer than aluminium, glass, plastic or wood, it cannot scratch any surface.
Why does it insulate?
It is actually not the wool itself that is responsible for the insulating properties, but the air trapped inside the felt, which acts as a poor conductor and prevents heat exchange. The wool fibres enclose the air so that it can barely circulate within the felt. In this case, the wool merely serves as a "natural carrier" of the air. That is why felt feels so pleasant in both warm and cold conditions.
Why doesn't it burn?
Wool is a highly heat-resistant natural fibre. Even under intense heat, it does not burn but chars at around 320°C. The density of the felt also makes it difficult for oxygen to reach the wool, which further inhibits combustion. It can withstand temperatures of up to approx. 220°C.
Why is it sound-absorbing?
The fibres dampen noise: when sound waves hit the felt, they are not reflected as they would be by a hard surface. The soft surface of the felt, with its irregular fibres and pockets of air, absorbs the sound.
