Which of the following is NOT a property of nylon?

Nylon is characterized by its various properties that make it a widely used synthetic fiber in textiles. Among these, excellent elasticity allows it to stretch and return to its original shape, making it ideal for applications such as swimwear and activewear. Its high strength contributes to the durability and wear resistance of garments and other nylon products.

The lightweight nature of nylon is another significant advantage; it allows for the creation of fabrics that are easy to wear and do not add excessive bulk. These properties make nylon a desirable material across a range of applications, from clothing to outdoor gear.

When considering moisture retention, nylon does indeed have a relatively low level compared to other fibers like cotton, which tend to absorb more moisture. However, it does still retain some moisture, particularly in humid environments, due to its hydrophilic nature when wet. Therefore, claiming it has low moisture retention inaccurately describes its behavior, making it the correct choice for the property that is not characteristic of nylon.
