What rag is the most absorbent ?
There are many absorbent rags. Generally speaking, 100 % cotton is the most absorbent, depending on the state of the material and the liquid that you are absorbing. New cotton often has sizing on it, a chemical used to protect fabric during shipping. This process prevents the material from absorbing liquids. Small amounts of polyester helps cotton to absorb faster by opening up the weave and allowing liquids to enter. Additionally, polyester is a petroleum based fiber which means that it will absorb petroleum based liquids, such as oil.
