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. Pay special attention not to oversize, and finally adjust it appropriately.

The operation should be carried out on the ironing table, and a blanket can be spread on the desktop at home. After all, it is best to heat, shape and cool with a photo machine.

2. Thick 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.

The use of fabric softener can improve the hand feel.

Steam the washed sweater in a steamer for about 15 minutes, then take it out and stretch it to its original size by hand, and put it on the table to dry naturally. Saving money won't hurt the sweater.

The method of restoring the shrunk sweater to its original state

Warm water is injected into the washbasin, a small amount of household ammonia is dripped, and then the sweater is immersed, and the soap components left on the wool will melt. Gently stretch the narrowed part with both hands at the same time, and then rinse it to dryness. When it is half dry, first open it by hand, straighten it, and iron it with an iron to restore its original size.
