Lyocell is a semi-synthetic fiber used to make textiles for clothing and other purposes. It is a form of regenerated cellulose made by dissolving pulp and dry jet-wet spinning. Lyocell is composed primarily of cellulose derived from wood. It is a type of rayon, but it is officially regarded as a sub-category of rayon. Lyocell shares many properties with other fibers such as cotton, linen, silk, ramie, hemp, and viscose rayon (to which it is very closely related chemically) . Some of the properties of lyocell include:

• Absorbency: Lyocell is 50% more absorbent than cotton, and has a longer wicking distance compared to modal fabrics of a similar weave. Consumers often say Lyocell fibers feel softer and "airier" due to their better ability to wick moisture.

• Strength: Lyocell is strong and resistant, making it a popular choice for conveyor belts and medical dressings.

• Sustainability: Lyocell is considered an eco-friendly semi-synthetic fiber because it is made of wood cellulose, usually from eucalyptus trees, which means it is made of a natural source. Its production process has a very low impact on the environment, and it is 100% biodegradable and compostable.

Lyocell fabric may be machine washed or dry cleaned. It drapes well and may be dyed many colors, needing slightly less dye than cotton to achieve the same depth of color. While some garments are made entirely from lyocell, it is more common to see this fabric mixed with other types of fabrics like cotton or polyester.
