Absorbency refers to the ability of a material to soak up liquids. This property is important in various products, such as sponges, towels, and diapers, which are designed to hold moisture. The level of absorbency depends on the material's structure and composition, influencing how much liquid it can retain. Different materials exhibit varying degrees of absorbency. For example, natural fibers like cotton are known for their high absorbency, while synthetic materials like polyester may absorb less moisture. Understanding absorbency helps in selecting the right materials for specific applications, ensuring effectiveness in tasks like cleaning or personal hygiene.
