Advantages of the raw materials
Wool – the natural material with character
100% pure new wool forms the basis of many of our felt qualities.
Wool is:
- Breathable, temperature- and moisture-regulating
- Elastic, durable and dimensionally stable
- Biodegradable and renewable
- Suitable for sound absorption and heat storage
Properties of wool:
- Environmentally friendly: sustainable, natural, energy-saving
- Health-promoting: breathable, binds pollutants
- Protective: flame-retardant, UV-resistant
- Other characteristics: crease-resistant, elastic, easy to care for
Viscose – the cellulose fibre
Made from natural cellulose (wood) using a wet spinning process.
Viscose is:
- Good moisture absorption
- A textured surface
- Biological origin
Properties of viscose:
- Decomposition temperature: 175–190 °C
- Natural & recyclable
- Antistatic, moderately acid-resistant
- Elastic, but limited tear resistance
Polyester – the technical all-rounder
Polyethylene terephthalate (PET) is used for many technical felt applications – for example in acoustics or as a carrier material.
Properties of polyester:
- Low moisture absorption (0.2–0.5%)
- High melting temperature (250–260°C)
- UV-resistant & smooth surface
- Temperature-resistant up to 150°C
- Low alkali resistance, but robust and versatile
