Which of the following fibers do not absorb moisture well?

The answer is found in the inherent properties of various fibers. Nylon is a synthetic fiber that is designed to be resistant to moisture absorption. Unlike natural fibers, which can readily take in water due to their porous structures and hygroscopic nature, nylon has a smoother surface that does not easily absorb moisture. This quality makes nylon an excellent choice for applications where water resistance is desirable, such as in outdoor gear and upholstery that may face exposure to moisture.

In contrast, fibers like rayon, cotton, and wool possess a high capacity for moisture absorbency. Rayon is derived from cellulose and absorbs moisture effectively, which can enhance comfort in clothing. Cotton is known for its breathability and ability to wick moisture away, making it comfortable to wear. Wool, while insulating, also retains moisture, providing warmth even when wet. Understanding these properties helps in selecting appropriate materials based on their interaction with moisture in different cleaning and maintenance scenarios.
