No matter what texture of clothes, how to restore their original appearance after shrinking? Steam ironing first shrinks the sweater fibers with a steam iron, and then stretches the fibers 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. Second, there is a way to enlarge the shrinkage rate of thick cardboard 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 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. 3. Send clothes to the dry cleaner, just take them to the dry cleaner, dry clean them first, then find a special shelf with the same model as the clothes, hang the sweater, and after high-temperature steam treatment, the clothes can be restored to their original appearance, and the price is the same as that of the dry cleaner. Reminder: After buying a sweater, pay attention to the label inside the clothes. Don't wash sweaters that need dry cleaning with water.
