What is lyocell
Last updated: April 1, 2026
Key Facts
- Lyocell is produced from sustainably harvested wood cellulose using an environmentally responsible manufacturing process that recycles 99% of solvents.
- The fabric is known for being soft, breathable, moisture-wicking, and durable, making it ideal for clothing, bedding, and home textiles.
- Tencel, owned by Lenzing Group, is the leading commercial brand of lyocell fiber used by major fashion and textile companies.
- Lyocell is more durable and wrinkle-resistant than traditional rayon and requires significantly less water and chemicals in production.
- The fabric is completely biodegradable and considered one of the most eco-friendly alternatives to synthetic fibers and conventional viscose rayon.
What is Lyocell?
Lyocell is a semi-synthetic cellulose fiber manufactured from sustainably harvested wood pulp. Unlike cotton, which requires significant water and pesticides, lyocell is created through a chemical process using a non-toxic solvent system that is almost completely recycled. This makes it an environmentally friendly textile option for the modern consumer.
Manufacturing Process
Lyocell is produced through a closed-loop lyocell process where wood pulp is dissolved in a solvent and then regenerated into fibers. The unique feature of this process is that approximately 99% of the solvent is recovered and reused, significantly reducing environmental impact. This is a major advantage over traditional viscose rayon production, which discards harmful chemical waste.
Properties and Characteristics
Lyocell fabric is exceptionally soft and smooth, often compared to silk for comfort. It is highly breathable and moisture-wicking, making it suitable for activewear and intimate apparel. The fabric is also more durable than rayon, resists wrinkles better, and holds dyes beautifully, resulting in vibrant colors. Additionally, lyocell is naturally thermoregulating, keeping wearers cool in summer and warm in winter.
Commercial Brands and Applications
Tencel, produced by the Austrian company Lenzing, is the world's largest producer of lyocell fiber and holds significant market share. Lyocell is used by major fashion brands and textile manufacturers for clothing, bedding, home furnishings, and even medical applications. Its sustainable credentials have made it increasingly popular among eco-conscious consumers and fashion brands.
Environmental and Sustainability Benefits
Lyocell production requires significantly less water than cotton cultivation and creates minimal toxic waste. The closed-loop manufacturing system ensures environmental protection while producing high-quality fiber. Unlike synthetic fibers, lyocell is completely biodegradable, breaking down naturally in soil or water, making it an excellent choice for sustainable fashion.
Related Questions
What is the difference between lyocell and rayon?
Lyocell and rayon are both cellulose fibers, but lyocell uses a closed-loop manufacturing process that recycles most solvents, while traditional rayon discards chemical waste. Lyocell is more durable, wrinkle-resistant, and environmentally sustainable than conventional rayon.
What is viscose fabric?
Viscose is a semi-synthetic cellulose fiber made from wood pulp using chemicals that are largely discarded as waste. While softer than many fabrics, viscose production is less environmentally friendly than lyocell and requires more chemical treatment.
What does 'closed-loop' mean in textile manufacturing?
Closed-loop manufacturing means that solvents and chemicals used in production are recovered and reused rather than discarded. This reduces waste, environmental pollution, and manufacturing costs, making closed-loop processes more sustainable.
