What is a key property of wool that contributes to its popularity in textile products?

Wool is celebrated for its excellent moisture absorption, making it a highly desirable material for various textile products. This property allows wool garments to wick away moisture from the body while still retaining warmth, which is particularly advantageous in colder climates. Unlike synthetic fibers, wool can absorb significant amounts of moisture without feeling wet, contributing to comfort and temperature regulation.

While the matte appearance is a characteristic of wool, it is not a key property that defines its popularity or functionality in textiles as moisture absorption and thermal regulation are more critical for usability in clothing and other textile applications. Other choices, like difficulty in dyeing and poor insulation, do not accurately reflect wool's attributes; in fact, wool typically dyes well and offers excellent insulation properties.
