2. Texture: The raised texture gives corduroy a soft, velvety texture that is pleasant to the touch.

3. Durability: Corduroy is known for its durability and is suitable for clothing and items that are often worn. Corduroy fabric also resists friction well and can maintain its appearance for a long time.

4. Warmth: The thickness and pile of corduroy have good thermal insulation properties, which is perfect for cooler weather.
