In selecting these draperies, make sure you know the specific care procedure the manufacture recommends. Some of these coatings react adversely in both drycleaning and washing. The International Fabricare Institute recommends that glass fiber draperies be washed and air dried rather than drycleaned, to avoid color loss and chalky streaks. Care must be taken to subject them to as little abrasion as possible. For sunny locations, use fabrics that are resistant to deterioration from sunlight.
Synthetics are more resistant than cellulose fibers, while silk is least resistant.
Line all draperies for protection against fading and fiber rotting. If you are using cotton and rayon fabrics, allow for changes in length caused by atmospheric changes. These fibers tend to expand when the relative humidity is high and contract when it is low. Remember that synthetic fibers pick up dust due to static electricity and that cotton and rayon tend to yellow as they age. Use care in sewing to avoid seam puckering.
