If you put spandex in the dryer, there are a few potential outcomes:
Shrinkage: Spandex is a synthetic fiber known for its elasticity and stretchiness. Subjecting it to high heat in the dryer can cause it to shrink. As a result, your spandex garment may become smaller and tighter than before.
Loss of shape and elasticity: Excessive heat can damage the structure of spandex fibers, leading to a loss of shape and elasticity. Your spandex garment may lose its stretchiness and become less form-fitting or saggy.
Fading or discoloration: Some spandex materials may be prone to fading or discoloration when exposed to high heat. Vibrant colors might become dull or fade, affecting the overall appearance of the garment.
Damage to embellishments or decorations: If your spandex garment has any embellishments like sequins, beads, or heat transfers, the heat from the dryer can cause them to melt, warp, or become damaged.
To maintain the quality and longevity of your spandex garments, it's generally recommended to avoid putting them in the dryer. Instead, consider air-drying them by laying them flat or hanging them up. If you must use a dryer, opt for a low-heat setting or use a garment bag to protect the spandex from direct heat exposure. Always refer to the care instructions provided by the garment manufacturer for specific guidance.
