felted

This term describes a specific physical state where fibers are entangled and compressed into a dense, non-woven mass. In textile contexts, it refers to the process of shrinking and matting wool, resulting in a fabric that does not fray and has a characteristic soft, thick texture.

In biological or botanical contexts, the term describes a surface covered in a dense, woolly layer of hairs. This is often used to describe the appearance of certain molds, fungi, or plant leaves, suggesting a velvety or matted tactile quality rather than individual distinct hairs.
