1. Put the deformed sweater in 60-100C water to soak it and let it slowly recover its shape. Generally, it can recover a little. If the fiber is completely deformed, it may take 100C water to restore the fiber. After recovery, put it in a bag and put it in the refrigerator. Then take it out to dry and recover. This can effectively solve the problem of deformation of most sweaters.
2. Use a steam iron to help. If you have the conditions at home, you can prepare a 100C steam iron, flatten it, shrink the sweater, and iron it.
3. When drying sweaters in general, in order to prevent the sweaters from getting bigger and longer, it is better to flatten the sweaters for drying, or open the umbrella and dry them directly. If you think it’s harder to dry it flat, you can also use two search and three hangers to put the wool hanger up to dry, and put the tail on the hanger.
