The optimal time for sun-drying quilts is between 10 AM and 2 PM when the air is dry. In winter, limit exposure to 1 PM. Quilts readily absorb moisture, so bring them in promptly. Additionally, avoid direct sunlight during drying. Covering the quilt with a sheet is advisable, but remember to flip it halfway through to ensure both sides receive even sun exposure.
Different Materials, Different Schedules
Sun-drying frequency and duration vary by quilt fabric:
Cotton quilts: Once weekly for 3-4 hours.
Synthetic fiber quilts: Once weekly for 2-3 hours is ideal.
Wool quilts: Twice monthly for 2 hours in a shaded area.
Down comforters: Air once a month. In summer, 30 minutes; in winter, one hour. Hang in a shaded area. Down comforters can be placed indoors over a chair, ensuring adequate ventilation.
Quilts unsuitable for prolonged sun exposure
Cotton quilts: Cotton quilts expand after 3 hours of sunlight. Excessive exposure or frequency may cause cotton fibers to shorten and shed, reducing warmth retention.
Wool and down comforters: Materials like wool and down contain natural oils. Prolonged exposure to sunlight causes chemical changes in these substances, degrading the quality of the comforter over time.
Silk quilts: Prolonged exposure to sunlight can break down the protein components in silk, causing discoloration and brittleness. Therefore, silk quilts should only be aired for two hours in a dry, well-ventilated area.
Best Season for Sun-Drying Quilts
Ideal Season for Sun-Drying
Experts recommend July and August as the optimal time for airing stored quilts. The intense ultraviolet rays during these months effectively kill parasites hiding within the quilts.
Unsuitable Season for Sun-Drying Quilts
May is unsuitable for sun-drying quilts. While sunny and filled with flying willow catkins, May is the breeding season for larvae. Winter eggs and larvae can easily be carried by the wind into quilts. Winter bedding typically contains keratin, an ideal food source for insect eggs. Frequent sun-drying during this period may accelerate moth infestation.
Precautions for Sun-Drying Quilts
1. When sun-drying quilts, position the inner lining toward the sunlight. This protects the outer fabric while allowing the lining to absorb direct sunlight for optimal drying.
2. Avoid vigorously beating the quilt after sunning. This can cause filling materials like fibers or down to break, compromising warmth. Simply brush off surface dust with a soft brush.
