Lyocell (Tencel)

Lyocell is a semi-synthetic fiber made from regenerated cellulose (typically wood pulp from eucalyptus, oak, or birch trees) using a closed-loop process with the non-toxic organic solvents, unlike open-loop processes and typically toxic solvents used in traditional rayon/viscose production. The resulting fiber is soft, breathable, moisture-wicking, naturally antimicrobial, biodegradable, and does not shed microplastics. Lyocell has a smooth surface with excellent drape, is stronger than rayon (especially when wet), and is more wrinkle-resistant than cotton or linen.

For plastic-free living, lyocell (especially Tencel brand) offers the best compromise between natural fibers and semi-synthetics - it combines the environmental responsibility and biodegradability of plant fibers with the performance and easy care of modern textiles, all without the toxic chemical processing that makes rayon/viscose problematic.

Apparel: Dresses, blouses, t-shirts, pants, underwear, sleepwear, casual wear

Activewear: Moisture-wicking athletic clothing, yoga wear, running shirts, sports bras

Bedding: Sheets, pillowcases, duvet covers, blankets

Home Textiles: Towels, curtains, upholstery, decorative pillows

Baby Products: Onesies, swaddles, sleep sacks, crib sheets

Accessories: Scarves, masks, linings, bags

Blends: Often mixed with cotton, linen, wool, or silk for various properties

Microplastic Concerns: Lyocell does not shed microplastics. Despite being chemically processed, lyocell is made from regenerated plant cellulose and is fully biodegradable. When lyocell fibers are released during washing, they break down into organic matter rather than persistent plastic particles, making lyocell clothing and bedding far safer than synthetic alternatives like polyester.

Chemical Safety: Lyocell production is one of the safest textile manufacturing processes. The NMMO solvent used is non-toxic (unlike the neurotoxic carbon disulfide used in rayon production), and the closed-loop system recovers 99%+ of the solvent, preventing environmental pollution and worker exposure. The final lyocell fiber contains virtually no residual chemicals. Lyocell is naturally hypoallergenic and gentle on sensitive skin. However, some lyocell fabrics may be treated with softening agents, dyes, or finishes after fiber production.

Certifications to Look For: OEKO-TEX Standard 100 ensures no harmful substances in the final fabric. GOTS (Global Organic Textile Standard) for organic lyocell production. FSC (Forest Stewardship Council) certification for sustainably sourced wood pulp. EU Ecolabel for environmental standards. Tencel brand ensures the highest processing standards - generic lyocell may not meet Lenzing's strict protocols.

Recommendations: Choose Tencel brand lyocell when possible - while other manufacturers produce lyocell, Tencel maintains the highest environmental and quality standards
