Title: Sublimation dying of textiles and other materials

Abstract: Sublimation dyeing uses first and second donors, with heat being applied simultaneously from both sides of the object. Receivers can be woven, non-woven, knitted or not knitted, or any combination of these, or any other factors, and are contemplated to include fabrics used for clothing, banners, flags, carpets, wall hangings, and so on. Process parameters use lower temperature and longer dwell times than for one-sided sublimation printing, most preferably dwell times of between 70 seconds and 120 seconds, and a sublimation temperature of less than 400.degree. F. (204.4.degree. C.). Solids and patterns can be reproducibly printed, even in small lots, and can facilitate just in time production of clothing and other materials.
