Not all fabrics are created equal when it comes to the dryer. Some materials thrive with heat, while others shrink, warp, or lose their shape. This guide breaks down the most common fabrics and tells you exactly how to dry them safely.
Cotton is one of the most dryer-friendly fabrics. It handles heat well and actually softens with repeated drying. Expect 3-5% shrinkage on the first wash/dry cycle for untreated cotton. Pre-shrunk cotton is virtually worry-free. Use medium heat for best results.
Polyester is heat-resistant and dries quickly. It rarely shrinks and maintains its shape well. Low to medium heat is ideal — high heat can cause pilling or slight glazing over time. Polyester blends (like cotton-poly) combine the best of both worlds.
Nylon can handle the dryer on low heat, but high temperatures may cause warping or melting. It dries very quickly, so shorter cycles are fine. Avoid dryer sheets with nylon activewear, as they can reduce moisture-wicking properties.
Linen can go in the dryer on low heat, but it wrinkles easily and may shrink up to 4% if exposed to high heat. Remove promptly and hang or lay flat to finish drying for best results. Many people prefer to air dry linen entirely.
Denim is essentially heavy cotton and handles the dryer well. Turn jeans inside out to preserve color and reduce fading. Medium heat works great. First-time drying of raw denim may cause noticeable shrinkage — this is normal and the fabric will stretch back with wear.
Heat is the enemy of spandex. Tumble drying degrades the elastic fibers over time, causing leggings, sports bras, and swimwear to lose their stretch and shape. Always air dry spandex-heavy garments. If a garment is only 2-5% spandex (like stretch jeans), low heat is usually fine.
Wool shrinks dramatically in the dryer due to felting — the combination of heat, moisture, and agitation causes wool fibers to lock together permanently. Always lay flat to dry. Some "machine washable" merino wool can tolerate a brief tumble on no-heat/air-fluff, but it's risky.
Silk is extremely delicate and should never go in the dryer. Heat damages silk fibers, causing them to become brittle, dull, and rough. Water staining is also a risk. Hang dry or lay flat in a well-ventilated area away from direct sunlight.
Rayon is prone to significant shrinkage in the dryer (up to 10%). It also wrinkles severely and may lose its drape. Air drying is strongly recommended. Some "high-twist" rayon blends are more resilient, but check the care label first.
Fleece (polyester-based) dries quickly on low heat. Avoid high heat to prevent pilling and static buildup. Skip the dryer sheets — they coat the fibers and reduce the fabric's insulating properties. A short cycle on low heat is all you need.
Always check the care label first. Our guide covers general fabric behavior, but specific garments may have special treatments or blends that change their dryer tolerance.
When in doubt, use low heat. Most fabric damage comes from excessive heat, not from tumbling itself. Low heat takes longer but is gentler on everything.
Remove clothes promptly. Leaving clothes sitting in a hot dryer causes wrinkles and can set creases that are hard to remove.
Separate by weight and fabric type. Heavy items (jeans, towels) take longer to dry than lightweight items (t-shirts, underwear). Mixing them means overdrying the light stuff.
