Start by soaking the garment in salt water, soak the garment in the salt water for about 30 minutes, then wash as usual. Not only will this reduce shedding of clothes, but it will also help disinfect and remove mites from clothes, and prevent clothes from fading. Hair loss can be caused by the quality of clothing. Better to find a business to replace it.
For long-haired cardigans, you can dissolve a tablespoon of starch in half a basin of cold water. Remove the sweater soaked in the starch solution. Don't twist them. After draining, place them in a small amount of laundry detergent water. Soak for 5 minutes, then rinse. Then put it in a mesh bag and hang to drain, wool sweaters don't like to lose hair.
Sweater shedding is the most common. If the wool content exceeds 30%, it is easy to lose hair. Many non-hair removal products are relatively low in wool, and most of this is a blend of wool and other fabrics.
Losing wool is inevitable, but the amount of wool shedding can be minimized. For example, new cardigans can shake the wool to allow as much fluff to fall off as possible.
Do not use too much force when cleaning. It is best to dry clean. If you wash by hand, do not wring it out. Dry it by squeezing out the water, and then keep the air unblocked, and try to keep the wool product as flat as possible. If dry cleaning conditions are not available, the temperature of hand washing should be moderate, not exceeding 30 degrees. It is best to clean wool products with a mild detergent to avoid shrinkage and pilling.
