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.

Thick cardboard. There is a way to enlarge the shrinkage of sweaters after washing. The specific method is: 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. Third, dry clean first, then find a special shelf of the same model as the clothes, hang the sweater, and after high-temperature steam treatment, the clothes can be restored to their original appearance.
