What is the most widely used of all natural fibers?

Cotton is recognized as the most widely used of all natural fibers due to its versatility, comfort, and breathability. It is cultivated in various regions around the world and is favored in both apparel and home textiles. The fiber is soft against the skin, making it ideal for a wide range of clothing items, from casual wear to formal attire. Additionally, cotton's ability to absorb moisture and allow air circulation enhances its appeal, particularly in warm climates.

In contrast, while wool is also a significant natural fiber, it has a more limited application primarily in colder climates due to its insulating properties. Silk, known for its luxurious texture and sheen, is typically used in high-end garments and is less common in everyday clothing compared to cotton. Synthetic fibers, while highly popular in the fashion industry for their durability and cost-effectiveness, are not classified as natural fibers. Hence, cotton's prevalence in various textile markets solidifies its status as the leading natural fiber used globally.
