The first trick: immerse the sweater in warm water at 30℃-50℃, or steam it in a pot for 20 minutes, let it slowly recover its shape until it basically recovers, and then put it in cold water to finalize the design. Finally, remember not to wring it out when drying, but to dry it flat. If the sweater is too long, this is a very effective method.

The second trick: inject warm water into the washbasin, drop a small amount of household ammonia water, and then soak the sweater, and the soap 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.

The third measure: pure wool clothes must not be washed by washing machine, and it is best to dry-clean or hand-wash. Because the surface of wool fiber is composed of many scales, once it is washed by washing machine, it will destroy its excellent performance and affect its appearance. Pour neutral detergent into warm water at about 30℃. After the detergent is stirred evenly, add clothes and pat gently with your hands. Wash it several times with warm water at about 40℃ until it is clean. Then add a little vinegar or softener to clean water, and finally put the sweater into a cloth bag and put it in a washing machine for dehydration 1-2 minutes. Smooth the rabbit sweater and iron it with a steam iron at 120℃- 140℃. The iron can't touch the rabbit sweater directly. The rabbit hair sweater can be flattened and dried after it is shaped. This is a very good way to solve the problem of how to do if the sweater is too long.

The fourth measure: when drying sweaters, in order to avoid the sweater from getting bigger and longer, it is best to lay the sweater flat and dry it, or hang the umbrella directly on it.
