Osnaburg is a medium to heavyweight coarsely woven cotton. Osnaburg can be made of 100% cotton or a cotton and polyester blend. Higher grades of finished osnaburg are known for their durability and can be used for mattress ticking, slipcovers, work wear and apparel. Osnaburg can also be used for industrial purposes as sack or bag material. It can also serve as a less expensive drapery or upholstery fabric. Osnaburg is most often used in its natural color, but it can also be dyed or printed.
