what are the three most commonly used fabrics in America?

It's difficult to pinpoint the *exact* top three most used fabrics in America without access to specific production and consumption data. However, based on general usage and popularity, here are three fabrics that are likely among the most common:

1. Cotton: It's the most widely grown natural fiber in the world and a staple in American clothing, bedding, and home furnishings. Its breathability, softness, and affordability make it a popular choice.

2. Polyester: This synthetic fiber is known for its durability, wrinkle resistance, and easy care. It's often blended with cotton to enhance its performance and used in a wide range of garments and home textiles.

3. Nylon: Another synthetic fiber, nylon is renowned for its strength, elasticity, and water resistance. It's commonly used in sportswear, outerwear, and hosiery.

Important Note: The actual ranking of these fabrics can vary depending on the specific application (clothing, home furnishings, industrial textiles, etc.) and the data source used.
