Introduction: What if Sustainability Could Be Woven Into Your Clothes?
Given that fast fashion causes water waste, pollutes the environment and clogs landfills, one special textile fibre called Lyocell is a real answer.
Think of a material that is silk-soft, lets air pass through like cotton and is as durable as polyester—but it all comes from trees and breaks down naturally. It’s Lyocell and that’s what it’s known for. It’s not just any fibre; it’s a textile that blends coziness, top performance and attention to the environment.
Whether you are a student, a designer or own Lyocell clothing, this guide explains all you need to know about this fibre.
What is Lyocell Fibre and How is It Made?
Lyocell fibres are produced by using natural products such as eucalyptus, beech and spruce trees. While viscose is made inside an open loop, over 99% of the solvent used for producing Lyocell is recovered in a closed loop for further processing that's what makes it environment friendly. I know that remembering these things will be complicated but at least we should know some basics and we should gather some informations about this.
Here’s how it all works:
Wood Harvesting
It all begins when fast-growing and environmentally friendly trees such as eucalyptus, are harvested. Such trees are frequently grown off-farm, so they do not interfere with farming practices.
Pulping
Pulping the wood chips is how cellulose is separated from the wood.
Solvent Dissolution
The fiber cells are disolved in a solution called N-Methylmorpholine N-oxide (NMMO) to provide a solid mass.
Fibre Formation
The completed solution is sent through spinnerets which turn it into fibres. Following, they are cooled, rinsed, dried and sized to be spun into yarn.
Closed-Loop Recycling
The leftover solvent and water are treated, reused and help make this one of the greenest ways to produce fibres.
Lyocell is different from viscose since it produces hardly any harmful emissions and is safer from start to finish, not least for those working in its production.
Technical Properties: What Makes Lyocell Perform Better?
Lyocell is about more than being sustainable, it also performs at a high level equivalent to or sometimes superior to other fibres.
- Tenacity: A dry lyocell thread supports about 3.2–3.8 cN/dtex in strength and remains strong by 85–90% even while wet. This is higher than viscose and comparable to polyester
- Moisture Properties: This fibres absorbs moisture twice as much moisture as cotton which helps it keep you cool and comfortable in humid climates.
- Skin-Friendliness: Because of its antibacterial and hypoallergenic properties, Lyocell can be used safely by people with sensitive skin and in hospitals.
- Temperature Performance: It starts to degrade at temperatures above 260°C, offering good thermal stability for daily wear and technical use
- Softness and Drape: Lyocell is favored in luxury and formal dress because it drapes well and appears soft with a silky touch due to its fibers.
- Fibrillation: Micro-fibrils appear in lyocell fibres when they are exposed to water and rubbing. However, this process can form pilling, yet it helps give denim and casual clothing a soft, suede finish.
The reasons why Lyocell is a Sustainable Fibre
Amongst other types of fabric, Lyocell has some of the best environmental credentials.
- Low Water Usage: Cotton takes an average of 10,000 litres of water for every kilogram of fibre. Lyocell manufacturing requires only a tenth to a twentieth of the water that it takes to make other similar materials.
- No Toxic Chemicals: Unlike viscose which utilizes unsafe carbon disulfide, Lyocell depends on the non-toxic and recyclable solvent NMMO.
- Biodegradability: If you bury it, Lyocell fabric will break down in compost or soil within 8–12 weeks and won’t leave microplastics behind.
- No Pesticides: Most trees for Lyocell production are grown naturally, without chemical pesticides or artificial fertilizers.
- Carbon Emissions: A 2023 LCA reveals that Lyocell manufacturing puts out 50% less CO₂ than cotton and as much as 70% less than polyester.
More and more, questions concerning the environment are included in what buyers expect, in compliance standards and in basic course materials for textile workers.
Where is Lyocell Used?
1. Fashion and Apparel
Lyocell is found in everything from T-shirts and blouses to formalwear and ethnic garments. The TENCEL™ brand of Lyocell is now used by high-street and luxury fashion brands worldwide.
2. Activewear and Athleisure
Its moisture-wicking and antibacterial properties make it perfect for yoga wear, gym apparel, and outdoor clothing.
3. Home Textiles
Bedsheets, pillow covers, towels, and curtains made from Lyocell feel soft and breathable, and resist bacterial odour build-up.
4. Medical Textiles
Used in nonwovens for wound dressings, surgical wipes, masks, and hygiene products due to its high absorbency and skin compatibility.
5. Technical and Industrial Use
Lyocell fibres are used in filters, insulation, and composites for automotive applications and soundproofing layers.
Innovations and Research in Lyocell
Lyocell is not just a finished product—it’s also a research topic. Here are some exciting innovations:
- Graphene-infused Lyocell: Used in wearable sensors and smart textiles for health monitoring.
- Lyocell-Alginate Composites: These combinations are showing promise in wound healing and drug delivery systems.
- 3D-Printed Lyocell: Sustainable prototyping and fashion sampling using digitally fabricated Lyocell threads.
- Circular Fashion: Brands like Stella McCartney, H&M, and Eileen Fisher are using Lyocell in their recyclable collections.
- Indian Innovations: NIFT and IIT-based research labs are working on Lyocell blends for antibacterial socks, heat-regulating shawls, and breathable uniforms.
Can Lyocell Replace Other Fibres?
Yes—and in many cases, it already has.
- Cotton: Lyocell offers similar comfort but requires far less water and no pesticides.
- Viscose: It provides better wet strength, softer texture, and lower emissions during production.
- Polyester: Although polyester has higher dry strength, it lacks Lyocell’s moisture handling and biodegradability.
- Silk: Lyocell is used as a cruelty-free silk alternative, especially in stoles, scarves, and linings.
Challenges of Lyocell (and How They’re Being Solved)
- Cost: Lyocell is more expensive than cotton or polyester, but as global demand and production scale up, the price gap is narrowing.
- Fibrillation Issues: This is managed through pre-treatment, blending, and special enzyme finishes during processing.
- Limited Sources: Major production is dominated by Lenzing AG, but more Indian and Chinese companies are entering the space.
- Care Sensitivity: Without proper treatment, Lyocell garments may shrink or pill in regular washes. Blends and finishing help overcome this.

Why Lyocell is Gaining Momentum in the Indian Textile Industry
Even though Lyocell has become widely used around the world, its impact in the Indian textile sector is growing visibly. As more importance is placed on eco-certifications, sending textiles to Europe and the U.S. and making sustainable clothing, Indian manufacturers are looking at Lyocell.
In domestic spinning mills, Lyocell is now often used in mixtures for superior shirting, innerwear, ethnicwear linings and tailored sarees. The reason why it’s gaining popularity is that it combines comfort with a low environmental footprint. Retail stores are now highlighting TENCEL™ Lyocell because city consumers are wanting to know more about their clothes’ origins.
In addition, the Indian Institute of Handloom Technology (IIHT), NIFT and DKTE are motivating students to investigate Lyocell blends, various wet process methods and comparative life-cycle reviews in their undergraduate and postgraduate assignments.
Lyocell is opening doors for small companies and young enterprises to create eco-friendly home goods, environmentally sound accessories and simple home and personal care products that break down over time. Lyocell suits India’s vision for a cleaner country and the rising interest in green options for all sectors.
As more knowledge and experience with Lyocell are gained by machinery providers and wet processors, the processing and finishing costs should fall. As a result, the creation of sustainable Lyocell textiles for various local and international markets can speed up.
Blending performance, eco-friendliness and adaptability, Lyocell should be a key part of textile development in India.
