The yarn used preferably has a count of 550 to 850 decitex, especially 680 to 750 decitex and may be an air textured polyester yarn. The fabrics produced are dense, heavyweight fabrics with a weight of at least 380 gms/square meter. They have superior abrasion and snag resistance and are suitable for use as upholstery fabrics particularly for vehicle seat covers.
