What is Lyocell Fabric?

Lyocell fabric, also known as Tencel lyocell, is a type of sustainable textile that is becoming increasingly popular due to its environmental and social benefits. Lyocell is made from wood pulp that is sourced from responsibly managed forests and is produced through a closed-loop manufacturing process that minimizes waste and reduces the use of harmful chemicals.

This makes lyocell an environmentally responsible alternative to traditional textiles, such as cotton or synthetic fibers. In addition to its environmental benefits, lyocell is also known for its soft, silky feel and excellent moisture-wicking properties, making it a popular choice for bed sheets and clothing.

With its combination of environmental responsibility and comfort, lyocell is an excellent choice for consumers who are looking for sustainable textiles.

How is Lyocell made?

Lyocell (Tencel) is a type of rayon fabric made from cellulose, which is derived from wood pulp. The process of making Lyocell is known as "dissolving pulp" or "closed-loop process". The production process involves several steps:

Wood Pulp: The wood pulp is obtained from fast-growing trees such as eucalyptus, pine, or beech, which are grown in sustainable managed forests.
Pulp Preparation: The wood pulp is cleaned, refined, and then dissolved in a solution of amine oxide, a non-toxic and biodegradable solvent.
Spinning: The cellulose solution is extruded through small holes, known as spinnerets, to create long threads. These threads are then washed and dried to remove any remaining solvent.
Weaving or Knitting: The threads are woven or knitted together to create the final fabric.
Finishing: The fabric is then finished according to the desired properties, such as wrinkle resistance, softness, or color.
Certification: Lyocell is certified by various organizations, such as the Global Organic Textile Standard (GOTS) and the Organic Content Standard (OCS), which establish strict guidelines for Lyocell production and ensure that products labeled as Lyocell are truly sustainable.

Benefits of Lyocell

Lyocell offers several benefits compared to traditional rayon and other fabrics:

“known for its softness, drape, and a silky feel, making it a comfortable and elegant fabric”

Environmentally friendly: Lyocell is made using a closed-loop process that minimizes waste and pollution, and it uses sustainable wood pulp sources, making it a more environmentally friendly option.
Softness and drape: Lyocell is known for its softness, drape, and a silky feel, making it a comfortable and elegant fabric.
Moisture absorbent: Lyocell has a high moisture absorbency, which makes it breathable and comfortable to wear in warm weather.
Durable: Lyocell fibers are strong, durable, and resistant to shrinking, stretching, and wrinkling.
Biodegradable: Lyocell fibers are biodegradable, which means they will break down naturally in the environment.
Sustainable: Lyocell is a sustainable fabric option, since it's made from sustainable wood pulp sources, it's produced using a closed-loop process, and it's biodegradable.
Versatile: Lyocell can be used to make a wide variety of clothing items, such as shirts, dresses, and pants, as well as home textiles, such as sheets and towels.

Are there Harmful Chemicals?

Lyocell production uses a non-toxic solvent called amine oxide, which is biodegradable and less harmful to the environment compared to the chemicals used in traditional rayon production.
The use of amine oxide in the Lyocell production process also allows for the recovery and reuse of the solvent, which minimizes waste and pollution.
The closed-loop process used in Lyocell production eliminates the need for harmful chemicals and reduces the environmental impact of the production process.
Lyocell fibers are biodegradable, which means they will break down naturally in the environment, and won't pose a harm to the environment like traditional rayon fibers.
Certifications such as Global Organic Textile Standard (GOTS) and Organic Content Standard (OCS) have strict guidelines for Lyocell production, which ensures that products labeled as Lyocell are truly sustainable, and that the production process is environmentally friendly and non-toxic.

In addition, lyocell fibers are not as breathable as cotton, which can make it less comfortable to wear in hot weather.

How is Lyocell production improving?

Lyocell production is continuously evolving and improving, with advancements in technology and research leading to more sustainable and efficient methods of production. Some ways in which Lyocell production is improving include:

“which reduces the environmental impact of Lyocell production”

Increased use of sustainable wood pulp sources: Lyocell is made from cellulose, which is derived from wood pulp. Advances in sustainable forestry management are making it possible to source wood pulp from sustainably managed forests, which reduces the environmental impact of Lyocell production.
Improved closed-loop process: The closed-loop process used in Lyocell production allows for the recovery and reuse of the solvent, which minimizes waste and pollution. Research and advancements in the closed-loop process are making it possible to recover and reuse even more of the solvent, further reducing the environmental impact of Lyocell production.
Increased traceability: Advancements in technology have made it easier to track the entire production process of Lyocell, from the wood pulp to the finished product, making it easier to ensure that products are truly sustainable and to monitor the environmental impact of the production process.
Increased use of sustainable and non-toxic chemicals: Research and development in the production process are leading to the increased use of sustainable and non-toxic chemicals in the process, which reduces the environmental impact of the production process and improves the safety of workers.
Increased efficiency: New technologies such as precision irrigation, digital farming, and the use of drones are being used in Lyocell production.
