This is normal.

Because during the processing of wool into wool, the hair follicles of the wool itself contain a lot of oil before processing and need to be degreased. Some manufacturers do not completely degrease the wool fiber, resulting in lipid The residue itself will have a stinky smell for a while. The manufacturer will add special fragrance to cover up the smell. It will not harm the human body. It will only produce an odor when it comes into contact with water. It will disappear after drying.

When washing woolen sweaters, it is best not to machine wash them, because it will cause the fluff to fall out, deform and become wrinkled and lint out. Just wash it by hand, use a mild neutral laundry detergent, and special silk detergent. Wool cleaning liquid is better, be careful to avoid using alkaline laundry detergent. Because cashmere has a protein structure, alkaline detergents will destroy the protein structure of cashmere, making cashmere fragile and lose its softness. The tensile force of the fiber will also become worse, and it will easily break, leading to shedding.

You can add white vinegar when washing. As a household item, white vinegar can not only sterilize and disinfect, but the acetic acid in it can neutralize alkaline detergent products, eliminate color and odor, and does not damage clothes. It is suitable for washing sheep. Soak your sweater with some vinegar, which will not only make it easier to wash, but also remove odors and make the sweater softer.
