Hello, the reason for pilling in clothes is friction. When the various surfaces of clothes rub against each other or against different surfaces, the yarns in the fabrics begin to pill. Then, these hairs become lint and get tangled with each other, forming bead-shaped balls. Natural fabrics, especially wool, cashmere and angora, are more prone to pilling. 😔 The risk of pilling in this product is lower compared to alternatives. 😇 If you encounter a pilling/lint problem, you can easily clean the product with lint removal machines.
