Soak the sweater in warm water at 30℃-50℃, or steam it in a pot for 20 minutes to let it slowly recover its shape, and then put it in cold water to set it. Finally, remember not to wring it out when drying, but to dry it flat. This is a very effective method when the sweater is washed too much.

Put the steam iron about two centimeters above the clothes with one hand, let the steam soften the fibers, and then shape the sweater with the other hand. With both hands like this, I hope that the sweater can be restored to the original state of tight fibers as much as possible.

Pour silk wool into warm water and stir well. Soak the sweater in it for 15 minutes and rub it as gently as possible. After washing, soak it in softener for three minutes. Don't wring it out. Just squeeze it into a ball and squeeze it out. Finally, put it in a clothes rack to dry evenly.

When drying sweaters at ordinary times, in order to prevent the sweaters from getting bigger and longer, it is best to spread the sweaters flat and dry them, or open an umbrella to dry them directly on them. If you feel that it is not easy to dry, you can also hang the sweater with two or three hangers and put the tail end on the hanger, so that the sweater will not be deformed.

Open a large cardboard box and cut the cardboard into human size according to the reasonable size of the sweater. After washing and dehydrating the knitted sweater, put the cardboard into the sweater to make it spread left and right, and shorten the length, then iron it with an iron and lay it flat to dry.

Soak the sweater in clear water, don't wring it out, fold it and put it directly into the net bag, hang it up and let the water drip naturally. When the sweater is still a little wet, take it out of the net pocket, put it on the platform, smooth the wrinkles by hand, and hang it to dry, so that the sweater will not get longer.

If the sweater can be washed, there are the following points to pay attention to:

Alkali-resistant neutral detergent containing no enzyme should be used when washing, preferably special detergent for wool. If you use a washing machine, you should use a drum washing machine and choose a soft program. If you wash it by hand, it is best to rub it gently, not with a washboard;

Wool fabric will shrink and deform in aqueous solution above 30 degrees, so it is advisable to soak in cold water for a short time, and the washing temperature should not exceed 40 degrees. Rub it gently, not vigorously. Machine washing must use laundry bags, choose light gear. Dark colors generally fade easily.

Squeeze and wash, avoid wringing, squeeze out water, spread it evenly and dry it in the shade or fold it in the shade; Wet plastic surgery or semi-dry plastic surgery can remove wrinkles and avoid sun exposure;

Softening agents should be used to maintain soft hand feel and antistatic properties.

Do not use chlorine-containing bleaching solution, but use oxygen-containing color to bleach.
