Aircraft fabric covering often used in the restoration of older types that were originally covered using traditional methods. The purposes of the fabric covering of an aircraft are: Pioneering aviators such as George Cayley and Otto Lilienthal used cotton-covered flying surfaces for their manned glider designs. The Wright brothers also used cotton to cover their Wright Flyer. Other early aircraft used a variety of fabrics, silk and linen being commonly used. Some early aircraft, such as A.V. Roe's first machines, even used paper as a covering material. Until the development of cellulose based dope in 1911 a variety of methods of finishing the
Wrinkle-resistant fabric heated to allow the chemicals to react with the cellulose molecules. In the reaction, the molecules of the fabric are bonded together to keep them from moving and causing wrinkles. For this reason, durable-press treated garments behave as synthetics. However, almost all the wrinkle resistant garments are made with poly/cotton blends fabrics. There are problems with the post-curing process, the final step of the treatment, because if the process is not done perfectly the garment gets damaged and can even turn yellow. Companies have overcome the post-curing issues by producing wrinkle-resistant clothes using pre-cured fabrics. In the 2000´s, fabric softeners
