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.
