There is no way to change it back to its original state, but it is still possible to enlarge it. The method of shrinking and enlarging the sweater after washing is as follows:

1, steam ironing

The fibers of the shrunk sweater are heated with a steam iron, and then stretched with both hands while it is hot. According to experience, due to the limited heating area of steam iron, in order to ensure uniform fiber stretching, sweaters are stretched locally, sectionally, sectionally and by heating.

The fiber can't be stretched much at a time, so it needs to be heated and stretched repeatedly. Know the total length of stretching before stretching, so as to know the stretching length of each segment. After all stretching, we should measure the total length with a ruler. If the length is not enough, we can repeat it.

2. cardboard?

Cut it into the size and shape of the original sweater with thick cardboard (cardboard of home appliance packaging box), and it is best to polish the incision with sandpaper to avoid hooking the sweater.

Put the sweater on the cardboard, fix the lower part with several hangers, then steam iron the sweater repeatedly at various parts with an electric iron, and take it off after it is completely cooled.
