1、Iron with hot water
Longer sweaters can be ironed with hot water between 70~80 degrees, and the sweater can be changed back to its original shape. However, it is important to note that hot water is too hot to make the sweater shrink to a smaller size than the original. At the same time, the method of hanging and drying the sweater should also be correct, otherwise the sweater can not be restored to its original shape. If the cuffs and hem of the sweater are not elastic anymore, you can just soak a certain part with hot water of 40~50 degrees, soak it for two hours or less and then take it out to dry, so that its stretchability may be restored.
2、Use a steam iron
You can use a steam iron to recover a sweater that has grown long after washing. Hold the steam iron in one hand and place it two or three centimeters above the sweater to let the steam soften the fibers of the sweater. The other hand is used to “shape” the sweater, using both hands, so that the sweater can be restored to its original appearance.
3、Steaming method
If you want to restore the deformation or shrinkage of the sweater, generally will be used “heat therapy” method. After all, the material of the sweater wants to recover, it is necessary to heat the sweater in order to soften the fiber, in order to play a role in recovery. For sweaters that have grown longer after washing, the steaming method can be used. Put the sweater in a steamer and steam it for a few minutes to take it out. Use your hands to sort out the sweater to get it back to its original shape. It is best to spread out the sweater when drying it so that it will not lead to a second deformation of the sweater!
