Why does wool coat shrink?
The main reason why woolen overcoats shrink after washing is wool fiber. Wool has a layer of scales on its surface, just like fish scales. Wool fibers will entangle with each other when rubbing or rubbing, and this entanglement will be aggravated by increasing the temperature or under alkaline conditions. This reaction is called wool fiber shrinkage.
How to restore wool coat shrinkage 1 and steam ironing;
The shrunk woolen coat should be heated with a steam iron first, and then the shrunk place should be gently pulled with both hands while it is hot until it is restored to its original state. In order to ensure the uniform stretching of woolen fibers, woolen coats can be stretched by local heating. Wool fiber can't be stretched much at a time, so it needs to be heated and stretched repeatedly. (It is best to heat, set and cool the camera after all the work is completed. )
2, cardboard plastic amplification:
Cut the cardboard into the size and shape of tweed coat, and polish the incision with sandpaper. Put the woolen coat on the cardboard and fix the bottom with several hangers. Then use a steam iron to steam iron all parts of the sweater repeatedly, and then take it off after it is completely cooled.
3. Send it to the dry cleaner:
Take the woolen coat to the dry cleaner, dry clean it first, then find a special shelf of the same model as the clothes, hang the woolen coat, and after high temperature steam treatment, the clothes can be restored to their original appearance.
Wool coats shrink and dry cleaners can recover.
Wool coats can be sent to dry cleaners for repair after shrinking. If it shrinks after washing, there is another way: make a larger human figure with wooden boards, put on the wool coat, pull it to the right size and iron it again. It's hard to find a humanoid board. You can make it bigger with anything. Sweaters can be ironed with steam. I suggest you go to a special laundry without dealing with them.
No shrinkage method for washing all wool clothes 1. Don't use any special detergent for sweaters. It is petroleum extract, which is very harmful to natural fabrics. 2. Don't wash with water higher than 35 degrees, otherwise the fiber will be twisted and the appearance will be "shrunk". 3. The soaking time shall not exceed 10 minute, and the total rinsing time shall not exceed 25 minutes. 4. Don't rub too hard to avoid man-made fiber kinking.
