The silkworm, the larva of the silkworm moth, builds a cocoon for pupation from a filament that is up to 900 metres long. It is performing the heaviest work in the process as it needs to wrap itself with up to 300,000 loops. To get 250 g of silk thread in silk production, some 3,000 cocoons are needed, which is approximately equivalent to about 1 kg.
Eglo has taken this method as a model for the production of Cocoon luminaires. A unique special formula licensed by Eglo from which an extremely resilient and elastic material is produced. Models of any kind can be covered with a diaphragm. The variety of shapes allows almost infinite possibilities and only the sky is the limit in terms of designer creativity.
The filament is sprayed onto the rotating frame until it is fully covered with the first layer of filament. A few hours later, the ‘cocoon’ is ready for the second step of its transformation – the coating. For this, a special coating material is being applied to the woven frame that combines the filaments with the effect that the shade receives an extremely elastic skin. Now, the material is flexible enough that it will withstand being exposed to high levels of stress and is always able to regain its original form. Finally, the luminaire model will receive a special varnish layer. It protects the shade against soiling and can be cleaned using a wet cloth.
