COS - Oscurante is a soft double-faced fireproof cotton cloth, which does not easily retain marks of folds and wrinkles.
It is a
twill-woven fabric and it is plushy on both sides, that makes its surface photo-absorbent and closes its weft.
Thanks to its high opacity to light, it is ideal for masking and lighting control applications and it is commonly used to create curtains, black
Stage maskings, black boxes, backdrops,
Flats,
Acoustic draperies and draperies of all kinds.
Its darkening properties are
dimout, that is, they reach their maximum in the black colour and decrease in the less dark colours, to the point that the lighter ones can be used as light diffusers (with a warm colour temperature for the natural colour and a cold one for the white), for example for the butterfly diffusers in movie sets.
Due to its sound-absorbing properties it is used to reduce reverberation and improve the acoustics.
Its essential characteristics and low production costs make it one of the most used materials by stage technology, both in theater and television, where it is also known as Molton and Commando Cloth.
