“Folding can lead to creases and creases can cause the fibers to break along the creases,” she says. Folds should be rounded with the acid-free tissue.
If a gown is going to be hung for storage, the hanger should be heavily padded and the cover on the dress should be a plain white cotton bag.
Hanging is a less preferable means of storage because of gravity’s pull and weight, she says. “Plastic bags are generally not acceptable for storage because they’ll trap moisture,” and do not create a barrier from light.
“Light is the biggest problem. Light is one of the things we work the hardest to control, and where we see the most damage re^tft from when we receive objects and we treat objects,” says Willman, who is at work inspecting the museum’s collection of first ladies’ gowns for necessary repairs.
The dresses, when on exhibit, are displayed behind glass in a dimly lit room. Light, in addition to causing obvious color change and fading over time, also damages a fiber’s chemical structure, Willman says.
Some unpreserved fabrics age better than others, Willman and Saidman say.
Generally, synthetics are more resistant to environmental hazards than natural fibers because they are inert, don’t react to humidity changes and are not as subject to light damage, Willman says of fabrics which hold up best.
