Sweaters shrink back to their original state after washing, including warm water soaking, towel wrapping, water spray setting, stretching setting and professional nursing.

1, soaked in warm water:

Soak the sweater in warm water for 30 minutes to 1 hour to fully absorb water and restore fiber elasticity. Then gently press the sweater to squeeze out excess water, but don't wring it out or rub it out.

2, towel packaging:

Wrap the sweater with a clean white towel, put it on a flat table, and gently iron it with a steam iron to make the sweater evenly heated. In this way, the fibers of the sweater can be restored to their original state by the heat of steam.

3. Water spraying settings:

Spray a small amount of water mist on the surface of the sweater, and then gently wipe it with a clean towel or cloth to keep the surface of the sweater moist. Then iron it gently with a steam iron, and be careful not to touch the surface of the sweater directly to avoid scalding.

4. Stretching and setting:

After the sweater is completely dry, stretch and set. Stretch the sweater to its original size, and then fix it on the hanger with thumbtacks or hairpins. This will gradually restore the fibers of the sweater to their original state.

5, professional nursing:

If the above methods can't solve the problem, you can consider sending the sweater to a professional dry cleaner or clothing care shop for processing. They have professional technology and equipment, which can help the sweater restore its original state.
