Sweater in the dryer: tips, care, risk reduction
Cashmere or merino wool knits are very delicate. For this reason, it is important to know how to wash and dry your sweaters to avoid irreparable damage, as well described in an article from Corriere della Sera. One question we want to answer, and that many ask regarding the care of delicate garments, is:
Can I put the sweater in the dryer?
Although it may seem convenient to dry a pullover in the dryer, this practice carries risks that could compromise the durability and appearance of your favorite garment. In this article, we will explore the dangers associated with drying sweaters in the dryer, alternative methods for drying them, and tips to ensure your wool or cashmere knits remain in optimal condition over time.
Dangers of drying sweaters in the dryer:
1. Shrinking of the sweater: sweaters made from delicate and natural yarns can easily shrink when exposed to high temperatures. Drying in a high-heat dryer can indeed cause the sweater to shrink, making it unusable.
2. Felting: knits made from natural fibers like wool are particularly sensitive to heat and friction. Drying in the dryer can cause the fibers to felt, creating a rough and uncomfortable texture on the surface of the sweater.
3. Deformation: the agitators and rotating paddles inside the dryer can deform the shape of the sweater, especially if it is made of lightweight fabrics or has details like embroidery or beads.
4. Color fading: the high temperatures of the dryer can cause the color of sweaters to fade, especially dark or bright ones. This can make the sweater lose its vibrancy and appear less visually appealing.

How to dry a wool or cashmere sweater?
1. Air drying: the safest method to dry sweaters is to lay them flat on a dry, clean surface, preferably on a towel. Make sure the sweater is completely dry before storing it in the wardrobe to prevent moisture buildup and mold.
2. Low temperature drying: if you must use the tumble dryer, first check the label to see if it is allowed, then select a low temperature or delicate setting and remove the sweater as soon as it is dry to avoid damage. Do not overload the dryer so the sweater can dry evenly. Place the sweater inside a laundry bag to protect it during the drying cycle.
Tips for sweater care:
1. Follow the label instructions: before washing or drying a sweater, carefully read the care label to know the manufacturer's recommendations regarding care and washing.
2. Gentle washing: use a gentle detergent and wash wool or cashmere sweaters by hand or in the washing machine on a delicate cycle to minimize the risk of damage.
3. Flat surface drying: when possible, dry sweaters by laying them flat on a dry surface to maintain the shape and structure of the garment.
4. Proper storage: store clean and dry sweaters appropriately, preferably folded rather than hung, to avoid fabric deformation.
5. Lint removal: use a comb to remove lint and pills (pilling) from sweaters to keep them clean and well cared for.
If you want to keep your sweaters in great condition over time, it is essential to avoid tumble drying and opt for gentler alternative methods. By following our advice, your sweaters will remain soft, beautiful, and durable for a long time.
