Wool should not be in direct contact with the skin. Sweaters should not be worn, because sweat grease will be adsorbed on sweaters, causing moths and mildew. When you first wear it, it's easy to get small balls on your sweater. Wear it for a long time and it will naturally wear off. Don't pull the ball off, or the wool fiber will be pulled out. Cashmere fiber is fine and easy to pilling after rubbing, so cashmere sweater is best worn as a coat. If you wear it inside, you should wear smooth and soft fabric underwear under the cashmere sweater. Because of the low strength of cashmere fibers and the poor cohesion between fibers, the strength of cashmere yarns is low. The fastness of cashmere sweater is worse than that of woolen sweater. When wearing it, avoid contact with hard objects such as belts, straps and mobile phones.
