It's a classic: you wash your clothes according to the care label, at the right temperature, and yet your shirt or pants feel smaller after washing. But why does this actually happen?
The fabric and fibers determine a lot
Shrinkage occurs primarily in garments made from natural fibers such as cotton, wool, or linen. These fibers contain water, which causes them to swell during washing. When the garment dries, the fibers contract, making the garment feel smaller than before.
For example: wool can shrink even at low temperatures, if it is exposed to mechanical stress, such as the machine moving the garment too much during washing.
Machine impact
The movement of the washing machine can contribute to shrinkage, even if the temperature is correct. If the garment is “knocked up” too much in the drum during spinning or during an intensive program, the fibers can contract. This is why gentle programs are best for delicate fabrics.
The drying method matters
How the garment dries is at least as important as the temperature during washing. Tumble drying often shrinks fibers further, even on garments that have survived the wash. Air drying on a hanger or flat surface is often best for maintaining size.
Care instructions to reduce shrinkage
-
Always follow the care label, but combine with a gentle program and low spin speed.
-
Air dry delicate garments instead of using a dryer
-
Use a laundry bag for small or delicate items
-
Wash garments that shrink separately the first few times
Summary
Shrinkage often occurs due to the natural properties of the fibers , but is also affected by the movements of the washing machine and drying method. With the right gentle washing and drying, you can reduce the risk of your favorite garments shrinking – even if the temperature is just right.
