Draperies and other window textiles play an integrated part in enhancing the comfort, beauty, and luxury of a room. A variety of fabrics are available to consumers for use as draperies. Although fabric selections, installation and use conditions of draperies vary, all draperies in general are exposed to more destructive conditions than either wearing apparel, carpet or upholstery.  Draperies may receive direct or indirect exposure to the harmful rays of sunlight. Draperies also interact with the air circulation system of each room. As a result they accumulate dust and dirt, as well as residues from cooking, smoking, heating and other combustion. Higher humidity and temperature conditions tend to accelerate the damage caused by these destructive conditions. Therefore various problems or changes in the draperies can occur as a result of use and exposure. Sometimes the changes occur so gradually that they are not even perceived until after cleaning.
