Final answer:
The correct answer is option 4) Wool. Wool is the most absorbent carpet fiber listed, which leads to a longer drying time compared to synthetic fibers such as nylon, polyester, and acrylic.
Step-by-step explanation:
Wool is a natural fiber that is well-known for its ability to absorb a significant amount of moisture, up to one-third of its weight in water, making it the most absorbent among the listed carpet fibers. This high absorbency means that wool carpets require a longer drying time compared to synthetic fibers like nylon, polyester, and acrylic. These synthetic fibers are more water-resistant and dry faster. Wool's absorbency can be advantageous for indoor humidity control, but it also makes it more susceptible to staining and requiring longer to dry after cleaning or exposure to moisture.
Wool is the most absorbent carpet fiber and requires a longer dry time compared to the other options. The structure of wool fibers allows them to absorb a significant amount of moisture. Additionally, wool has a higher moisture regain capacity, meaning it can hold more moisture and take longer to dry.
