Yes, a shirt can continue to shrink each time it is run through the dryer, especially if it is exposed to high heat settings. The shrinkage occurs because most shirts are made from natural fibers like cotton, which have a tendency to contract when exposed to heat and moisture.
Here's why this happens:
Natural fiber properties: Cotton fibers have a three-dimensional structure, and when exposed to heat and moisture in the dryer, they can compress and tighten, causing the fabric to shrink.
Laundry mistakes: Sometimes, a shirt may not shrink much after the first drying cycle, but if it accidentally ends up in the dryer again and again, it can experience cumulative shrinkage with each cycle.
Aggressive drying methods: Using high heat settings or over-drying clothes in the dryer can exacerbate shrinkage. Hot air can cause the fibers to contract further, leading to additional shrinking.
To minimize excessive shrinking, consider the following tips:
Air drying: Instead of using the dryer, try air-drying your shirts on a clothesline or drying rack. This method is gentler on fabrics and reduces the risk of further shrinkage.
Low heat settings: If you must use the dryer, opt for low heat settings to reduce the impact of heat on the fabric.
Follow care instructions: Always follow the care instructions on the shirt's label. Different fabrics may have specific guidelines for washing and drying.
Stretching after washing: When the shirt is slightly damp, gently stretch it back to its original shape to counteract some of the shrinkage before it dries completely.
Remember that synthetic materials like polyester are less prone to shrinking compared to natural fibers. However, it's essential to treat all clothing items with care to maintain their original size and shape.
