Lyocell Fabric, also known as Tencel, is a type of rayon fabric made from cellulose fibers. It is produced using a process called the Lyocell process where purified wood pulp or cotton is dissolved and then extruded through a spinneret into a coagulation bath as filaments. These cellulose filaments are then processed into fibers and spun into yarns or sold as pulp for use in nonwoven applications.

The Manufacturing Process of Tencel

The manufacturing process of Tencel starts with sustainably sourced wood pulp which is usually obtained from timber plantations. In the process, this pulp is broken down into individual cellulose fibers and dissolved in an amine oxide solvent. The solution is then pumped through fiber extrusion holes into an aqueous coagulation bath where it forms a fiber. These fibers are washed, dried, and processed further. Some key aspects of the lyocell manufacturing process include:

- Dissolving the pulp in the amine oxide solvent which does not produce harmful derivatives. This solution enables fiber formation.

- Continuous mechanical action of extrusion and jet spinning form cellulose-rich fibers from the spinning solution.

- Coagulation bath regenerates cellulose structure from the solution into solid filaments.

- Filaments are stretched, washed, and dried before being spun into lyocell yarn or pulp.

- The amine oxide solvent is recycled and reused in a closed-loop system.

The Lyocell Fabric process is more eco-friendly compared to other regenerated cellulosic fibers as it uses a closed-loop solvent system without producing harmful byproducts.

Properties and Benefits of Lyocell Fabric

Some key properties and benefits of Tencel include:

- Soft and breathable: Tencel has a soft, smooth texture and feels lightweight on the skin. It is highly breathable which makes it suitable for activewear and summer garments.

- Absorbent: It has excellent moisture absorption properties and can absorb up to 30% of its dry weight in moisture without feeling wet.

- Biodegradable: Lyocell is one of the most biodegradable regenerated fibers. It breaks down quickly in soil or marine environments without polluting them.

- Durable: Despite being soft, lyocell is remarkably strong and durable. It maintains shape well and withstands wear and tear better than other rayon varieties.

- Hypoallergenic: Lyocell releases very low amounts of lint and is hypoallergenic, making it gentle and suitable for sensitive skin.

- Eco-friendly production: The closed-loop solvent system and use of sustainably sourced wood ensures lyocell has a lower environmental impact compared to other man-made fibers.

Applications of Lyocell Fabric

Due to its attractive properties, Tencel finds various applications:

- Apparel: It is used in making dresses, shirts, pants, underwear, activewear, and outdoor garments due to its breathability.

- Home furnishing: Lyocell yarn is used to make sheets, towels, curtains due to its absorbency and smooth drape.

- Industrial use: Nonwoven lyocell pulp is utilized to make filters, wipes, medical fabrics like surgical gowns.

- Accessories: From socks and tights to bags, backpacks, shoes - lyocell enhances the functionality and comfort in various accessories.

Why is Lyocell Fabric Considered Eco-friendly?

Unlike traditional rayon production, the lyocell process incorporates sustainability features:

- Wood pulp is sourced responsibly from managed forests through controlled tree farming.

- The amine oxide solvent is completely recycled internally without contamination. No hazardous chemicals are released into the environment.

- Lyocell fibers can biodegrade 25x faster than plastic in appropriate conditions without harming soil quality or releasing toxic residues.

- Production requires less energy compared to viscose rayon or synthetic fibers like polyester.

-Traceability ensures socially responsible manufacturing practices from wood sourcing to textile production.

- It helps reduce dependence on oil-based synthetic fibers through a bio-based and biodegradable alternative.

With controlled sourcing, solvent recycling, and improved degradation, lyocell has significantly lower environmental impact than other regenerated cellulosic fibers or plastics. It supports the circular economy principles of reduce, reuse and recycle.
