can sweaters be machine washed?
no.
When washing by machine, the washing machine will mainly rely on greater mechanical force to increase the friction between the clothes and the machine wall, so as to achieve the purpose of cleaning. Sweaters are made of wool, which will be seriously deformed and shrunk due to the influence of this mechanical external force, and the fabric will be damaged to a certain extent, so it is not recommended to wash sweaters by machine.
Precautions for cleaning woolen sweaters
1. Keep the water temperature at about 35℃, and never throw woolen sweaters into the washing machine for cleaning
2. Wash woolen sweaters with neutral detergent, which is alkaline and easy to damage the fabric structure.
3. Sweaters can't be spun off by washing machine or directly wrung out by hand. It's suggested that the water of sweaters be squeezed out slowly.
4. Hand-washed sweaters should not be rubbed vigorously. When drying, try to dry them flat to avoid deformation and shrinkage.
What should I do if the sweater shrinks?
It is almost impossible to restore it except for professional shaping. Cut it into a sweater shape slightly larger than your original size with cardboard. Then, spray more water, and then iron with steam. Barely, of course, the professional high-temperature iron is of better quality and better effect. All kinds of sweaters must not be washed with hot water and washing machine, otherwise shrinkage is not negotiable. Warm water is injected into the washbasin, a small amount of household ammonia water is dripped, and then the sweater is immersed, and the soap components left on the wool will melt. Gently stretch the reduced part with both hands at the same time, and then rinse to dry. At the time of half-drying, first open it by hand, make the original shape, and iron it with an iron to restore the original size. Usually when cleaning ~ the more detergent you can avoid ~, the principle is to wash it once. Warm water+a small amount of household "ammonia" = ammonia water. After soaking the shrunk sweater, you can break down the "naughty" soap into molecules. Gently pull open the narrowed part of the baby sweater and flush it. Please iron the sweater while shaping it.
