Part of the ‘Antique Fabrics‘ series, this fabric isn’t necessarily extinct, but it was more popular in the past than the present.
I’ve spotted this one in my 19th century catalog reprints. At that time, it seemed to refer to a hard wearing woolen or wool-silk originally woven in Turkey – hence the name.
Classic and Modern Fabrics states that contemporary ottoman fabric is a heavyweight woven with cords running either parallel to the weft (“ottoman rib”) or parallel to the warp (“ottoman cord”). If the ribs are narrow, it may be called soleil.
Ottoman made with cotton yarns may be used for shirts, and when composed of other yarns, it may be used for suiting fabric, or for upholstery.
