Micro-fleece sheets are luxuriously soft and keep you warm on chilly nights. Don't treat your micro-fleece sheets as you would other fabrics, such as cotton, as this can cause irreversible damage to the material. Take precaution when washing micro-fleece, and you will have soft sheets for many years to come.
Lint, or visible concentrations of fabric fibres, can attach to micro-fleece, so avoid washing micro-fleece with towels or other linty fabrics, like cotton. Because fleece can generate static electricity, it attracts and holds onto lint easily. If you need to remove lint, use the sticky side of a piece of tape or purchase a pre-made lint roller to pull off pieces of lint.
Pills are tiny clumps of fibre that form on the surface of a fabric as a result of friction. Washing your micro-fleece in warm water can cause premature piling. Instead, wash your sheets in cold water on a gentle cycle, then air dry, or machine-dry on a low heat setting. To further minimise piling, turn the cloth inside out, if possible, and wash with similar materials. You can shear the fabric occasionally if piling occurs and the pills don't fall off naturally.
Dry washing powder can clump and cling to micro-fleece even through washing. If you're using a powdered washing powder, dissolve the detergent in liquid prior to adding it to the wash load, or dissolve it in the machine prior to adding the fleece. You can also use liquid detergent to minimise leftover detergent residue.
Heat and Chemicals
Heat and certain chemicals commonly used in laundry can ruin your sheets, so avoid using them. High heat can melt micro-fleece fabric, so don't iron, steam, press or dry clean your micro-fleece sheets. Also, avoid using harsh chemicals like bleach or fabric softener. Bleach can break down the micro-filaments, thus reducing the soft feel of micro-fleece. Fabric softener can overwhelm the micro-fibres, essentially clogging them, weakening the water-repellent nature of micro-fleece.
