How to Care for Modal Fabric: Keep Your Lounge and Underwear Soft

Quick Answer

To keep modal fabric soft and smooth, wash it in cold water on a gentle cycle, use a mild detergent, and dry it flat or on low heat. Avoid fabric softeners and high heat, which can break down the fibers and reduce softness.

Modal is a popular choice for loungewear and underwear because it feels incredibly soft against the skin and drapes beautifully. Whether you’ve just bought a new modal pyjama or a comfortable lounge jacket, proper care will keep that luxurious feel for years.

The good news: caring for modal is straightforward. With the right washing and drying habits, you can prevent pilling, fading, and shrinkage, and enjoy your favorite pieces for a long time.

Why Modal Fabric Needs Special Care

Modal is a semi-synthetic fiber made from beechwood pulp. It’s known for being softer than cotton and more breathable than many synthetics, but it’s also more delicate than you might think. The fibers can weaken when exposed to high heat or harsh chemicals, leading to roughness and loss of shape.

Understanding what modal is helps you see why care matters. Because modal is often blended with other fibers like elastane or silk, each garment may have slightly different needs. Always check the care label first, but the general rules below apply to most modal pieces.

• Check the care label on each garment—blends may have specific instructions.
• Modal is prone to snagging, so avoid washing with items that have hooks or zippers.

Washing Modal: Step-by-Step

Washing modal correctly is the foundation of keeping it soft. Start by turning your garments inside out to protect the outer surface from friction. Use cold water (below 30°C/86°F) and a gentle cycle on your washing machine. If you prefer hand washing, use a mild detergent and lukewarm water.

Choose a detergent that is free of bleach and optical brighteners, as these can dull colors and weaken fibers. Avoid fabric softeners—they coat the fibers and reduce breathability, making the fabric feel less soft over time. Instead, add a splash of white vinegar to the rinse cycle if you want extra softness, but test on a small area first.

• Never wring or twist modal fabric—gently press out excess water instead.
• Wash modal with similar colors to prevent dye transfer.

Drying and Ironing: Keep It Gentle

The way you dry modal has a big impact on its softness and fit. High heat in the dryer can cause shrinkage and make the fabric feel stiff. The safest method is to lay the garment flat on a clean towel, reshape it gently, and let it air dry away from direct sunlight. If you must use a dryer, choose the lowest heat setting and remove the item while it’s still slightly damp.

Ironing is usually unnecessary if you dry modal properly. If you do need to remove wrinkles, use a cool iron and place a cloth between the iron and the fabric to avoid shine or damage. Steaming is an even safer alternative.

• Never hang modal to dry—the weight of water can stretch the fabric.
• If using a dryer, add a few dry towels to reduce drying time and friction.

Your Modal Care Routine in 5 Steps

1. Read the care label: Check for specific instructions, especially for blends like modal with silk or elastane. Different blends may require different temperatures or cycles.
2. Turn inside out and wash cold: Protect the outer surface and use cold water on a gentle cycle with a mild detergent. Avoid fabric softeners and bleach to preserve softness.
3. Dry flat: Lay the garment on a towel, reshape, and air dry away from heat and sunlight. Never wring or hang—this prevents stretching and misshaping.
4. Use low heat if machine drying: If you must use a dryer, select the lowest heat and remove while slightly damp. High heat can cause shrinkage and stiffness.
5. Store properly: Fold modal items rather than hanging them to maintain their shape. Proper storage prevents stretching and keeps your pieces looking new.
