A flame resistant fabric is formed from synthetic fibers, such as polyester fibers or non-aramid polyamide fibers. A first flame retardant is incorporated into the fibers by being intimately mixed with the polymer used to form the fibers. A second flame retardant is then surface applied to the fabric or to the yarns used to form the fabric. The fabric has a total flame retardant compound concentration of at least 5000 ppm. In one embodiment, the fabric can be combined with other fabric layers to produce a composite fabric product.

Flame resistant fabric and garment

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 fabric is constructed by weaving on a loom, with a loom setting of between about 78%-88% in the greige, using false twist textured polyester warp yam (about 140-160 denier, preferably about 150 denier with about 55-65 filaments in either single or 2 ply form) and air textured polyester weft yam (2-ply or 3-ply about 140-160 denier, preferably about 150 denier with about 90-110 filaments, preferably about 100 filaments), and finishing the fabric by scouring (on a jet or on a continuous scouring range) and printing or jet dyeing, and then heat setting at temperature of at least about 350.degree. F. The fabric scores between 4.5 and 5.0 on each of random tumble pilling, brush pilling, and Klopman method roughing and pilling, tests. The fabric also has a surface SMD of at least about 4.3, a bending rigidity 2HB of about 0.1 or less, a compressibility EMC% of less than about 28, a shearing stiffness G value of about 2 or less, and an extensibility EMT% of at least about 3.0. The fabric is especially suitable in the hospitality trade, e.g. for curtains and bedspreads.
