The sweater will be particularly uncomfortable when it is shrunk, but how can we avoid shrinkage? Here are five ways to solve the shrinkage problem. How can wool clothes shrink after washing Wool coat 1、 Steam ironing The shrunk wool clothing fiber is heated with a steam iron, and then the fiber can be elongated with both hands while it is hot to restore its original size. Note: (1) Due to the limited heating area of steam iron, in order to ensure uniform fiber stretching, the method of local, sectional, partial and heating stretching is adopted for wool clothes. (2) It is impossible to stretch a lot of fibers at one time. It is necessary to heat and stretch repeatedly. (3) Before stretching, you should know the total length of stretching, so as to know the stretching length of each section. After all stretching, you should measure the total length with a ruler. If the length is not enough, you can repeat it. (4) Pay special attention not to pull the size too far, and finally make appropriate adjustment. (5) The operation should be carried out on the ironing table. At home, a layer of blanket can be spread on the table. After all, it is best to heat, shape and cool the camera. 2、 Amonia water (1) Inject about 30 ° warm water into the laundry container and drip a small amount of household amonia water; (2) Immerse the wool coat in water, and the soap left on the wool will dissolve; (3) Gently lengthen the reduced part with both hands at the same time, flush and dry; (4) Before half drying, open it by hand, straighten it out, and iron it with an iron to restore it to its original state. 3、 Thick paperboard (1) Cut thick cardboard (cardboard of household appliance packaging box) into the size and shape of the original wool clothes; Note: the cut should be polished with sandpaper to avoid damaging the sheep sweater. (2) Put the wool clothes on the cardboard, and fix the lower feet with several clothes dryers; (3) Then use an electric iron to steam iron each part of the wool coat repeatedly, and remove it after it is completely cooled. 4、 Steamer For serious shrinkage, we can use hot steaming and stretching to restore the wool garment to its original state, as follows: (1) Wash the wool coat first; Use warm water of about 30 ° and an appropriate amount of neutral detergent (or shampoo, special detergent for wool clothes, etc.) to gently squeeze and clean the wool clothes. The practical ratio of water to washing products is about 30:1, and then wrapped with dry cloth for extrusion dehydration, (2) Prepare the steamer, add an appropriate amount of water and bring to a boil; (3) Put the washed wool clothes into the steaming drawer, steam for 10 minutes, then stop fire and take out the wool clothes; Note: wrap the wool sweater with a clean cloth (preferably white cloth to prevent color fading) and steam it together to prevent the wool garment from getting dirty. Generally, it can be taken out when the wool garment becomes wet and steams. (4) Put the wool coat on the cardboard, and pull the corners, neckline and cuffs into the size of cardboard. And fixed with pins or clips, individual parts can be stretched by hand. Note: before stretching, you should know the total length and the length ratio of each part of the wool garment, and you can't stretch too much at one time. After all pulling, measure the total length with a ruler. If the length is not enough, repeat it. (5) After completely cooling, remove the cardboard, spread the wool coat flat and dry in the shade, and the wool coat can return to its original size. 5、 Dry cleaners (1) Take the clothes to the dry cleaner for dry cleaning first; (2) Then find a special shelf of the same model as the clothes and hang the wool clothes; (3) The wool clothes will be treated with high-temperature steam. After that, the clothes can be restored to their original appearance. How to prevent shrinkage of wool clothes (1) When washing, squeeze gently by hand. Do not rub, knead or twist by hand. (2) After washing, squeeze out the excess water by hand, then wrap it with a dry cloth and press it to dehydrate it. (3) After dehydration, spread the sweater in a ventilated place to dry. When drying quickly, stretch the wool garment to restore its original size.
