Regenerated Fibre:
Regenerated fibers are a type of synthetic fibers that are produced by chemically processing natural materials such as wood pulp, cotton linters, or bamboo to create a fiber that can be spun into yarn. These fibers are sometimes referred to as "man-made natural fibers" because they are derived from natural materials but undergo a chemical transformation to become a usable fiber.

Types of Regenerated Fibers:
There are several types of regenerated fibers, including:

1. Rayon: Rayon is one of the most commonly used regenerated fibers. It is made from cellulose obtained from wood pulp or cotton linters. Rayon is known for its softness, high absorbency, and ability to drape well. It is often used in clothing, upholstery, and bed linens.

2. Viscose: Viscose is another type of regenerated fiber that is made from wood pulp or cotton linters. It is similar to rayon in terms of its properties and uses. Viscose is often used in clothing, particularly in the production of lightweight and breathable fabrics.

3. Modal: Modal is a type of regenerated fiber that is made from beech tree pulp. It is known for its softness, smoothness, and ability to retain its shape well. Modal is commonly used in clothing, particularly in the production of underwear and loungewear.

4. Lyocell: Lyocell is a type of regenerated fiber that is made from wood pulp, typically sourced from eucalyptus trees. It is known for its strength, durability, and ability to absorb moisture. Lyocell is often used in clothing, bedding, and home textiles.

Answer:
Among the given options, Rayon is known as a regenerated fiber. It is derived from wood pulp or cotton linters and exhibits properties similar to natural fibers. Rayon is widely used in the textile industry for various applications due to its softness, absorbency, and draping qualities.
