Pure cotton is a fabric made of natural cotton fiber, which has the characteristics of good air permeability, strong hygroscopicity, softness and comfort. It is skin-friendly, does not easily cause allergies or irritation, and is suitable for sensitive skin and babies. In addition, pure cotton fabrics do not add chemicals, and will not produce harmful substances that affect human health. In contrast, cotton silk is a blended fabric of cotton and silk, and some chemical dyes and finishing agents are usually added, which may cause irritation or allergic reaction to the skin. So from the health point of view, pure cotton is the first choice.
