Faille
Type of corded fabric
From Wikipedia, the free encyclopedia
Faille is a type of cloth with flat ribs, often made in silk. It has a softer texture than grosgrain, with heavier and wider cords or ribs. Weft yarns are heavier than warp, and it is manufactured in plain weaving. It was especially popular in the 19th century.

Material
Faille was primarily made with silk, variations with cotton and wool were also there. A French silk variant was called ''Faille Française.''[1][2] The similar grosgrain has been described as a "firm, stiff, closely woven, corded fabric. The cords are heavier and closer than those in poplin, more round than those in faille."[3]
Variations
Faille fabric is characterized by its prominent rib and is manufactured by employing fine filament yarns in the warp and heavy spun yarns in the filling. Typically, it is a heavyweight fabric, although lighter weight variations of faille, known as tissue failles.[4]
