Abstract
A room darkener fabric has about 40-60% of flame-resistant warp yarns on a face and 60-40% on the back. The warp yarns produce a fire-resistant barrier for a middle layer of non-flame resistant black yarn. About 70-90% of the black filling yarns binds with the warp yarns and forms a middle layer so that both the face and back comprise approximately 85-95% white warp yarns and 5-15% black filling yarn, with the balance of the black filling yarns forming the middle layer. The filling yarn is a non-flame resistant yarn that is solution dyed black.

A room darkener fabric comprising:
- a woven fabric having three layers of yarns with each layer interlaced between warp and filling yarns;
- said warp yarns being white and flame resistant and having about 40-60% of said warp yarns on a face of the fabric and about 60-40% warp yarns on a back of the fabric;
- said filling yarns being non-flame resistant black yarns;
- about 70-90% of said black filling yarns binding with the warp yarns and forming a middle layer such that the face and back include about 85-95% white warp yarns and about 5-15% black filling yarn with the balance of the black filling yarns forming a middle layer whereby substantially less than 2% of visible light is transmitted through the fabric.
