Microterry (or microfiber terrycloth) is 80% polyester and 20% polyamide fabric. Polyester can’t absorb moisture but there are thousands of tiny fibers in this fabric that actually trap the moisture between them. That is why it is able to hold many times its weight (up to eight) in moisture, unlike cotton and other soaker fabrics. It is great for diapering because it’s light, absorbs quickly, and dries quickly. It is best to dry microterry on low or line dry. Most of our liners are colored because it’s fun and conceals any staining that may occur; bleach will not affect the color.
