Does Lyocell Shrink? Understanding and Preventing Shrinkage

Yes, lyocell can shrink, typically by 3-5% after the first few washes. But don’t worry, this guide will teach you how to minimize shrinkage and keep your lyocell garments looking their best. We’ll cover everything from washing and drying to ironing and troubleshooting, plus we’ll clarify the Tencel vs. lyocell question and delve into the eco-friendliness of this popular fabric.

Understanding Lyocell Shrinkage: Why It Happens and How to Prevent It

Lyocell, known for its softness and luxurious drape, is made from wood pulp, typically from eucalyptus trees. These cellulose fibers are sensitive to heat, which is the primary culprit behind shrinkage. Imagine the fibers as tiny springs: heat causes them to constrict, resulting in a smaller overall size. So, how do you keep those fibers relaxed and happy? The key is gentle care, starting with the right washing techniques.

Washing Lyocell: A Step-by-Step Guide

  1. Hand Washing (The Gold Standard): Fill a clean basin or sink with cool water (around 86°F or 30°C). Add a small amount of mild detergent designed for delicates. Submerge your lyocell garment and gently swirl it around. Avoid harsh scrubbing or twisting. Rinse thoroughly until all traces of detergent are gone. Gently squeeze out the excess water – no wringing!

  2. Machine Washing (Proceed with Caution): If hand washing isn’t feasible, you can use a washing machine, but choose a gentle or hand-wash cycle with cold water. A mesh laundry bag offers added protection. Use a mild detergent and skip harsh chemicals like bleach.

Drying Lyocell: Air is Your Best Friend

Heat is lyocell’s nemesis, so air drying is the best way to preserve its shape and size. Lay the garment flat on a clean, dry towel, or hang it on a padded hanger. Avoid direct sunlight, which can fade the color. While some sources suggest tumble drying on the lowest heat setting for a short time, this is generally not recommended, as even low heat can cause some shrinkage.

Ironing Lyocell: Low and Slow

If ironing is necessary, use the lowest heat setting possible and always iron on the reverse side. Steaming is an even gentler alternative for smoothing out wrinkles.

Lyocell Care: Do’s and Don’ts

Do Don’t
Hand wash or machine wash (delicates cycle, cold water) Wash in hot water
Use mild detergent Use bleach or harsh chemicals
Air dry flat or on a padded hanger Tumble dry on high heat
Iron on low heat (inside out) Leave garment soaking for extended periods
Pre-soak new items in cold water Scrub or twist when washing

Tencel vs. Lyocell: What’s the Difference?

Tencel is simply a brand name of lyocell, like Kleenex and tissues. All Tencel is lyocell, but not all lyocell is Tencel. Care instructions are identical.

Lyocell and the Environment: A Nuanced Perspective

Lyocell is often touted as eco-friendly due to its sustainable sourcing (wood pulp) and closed-loop production process, which reduces water and chemical usage. Additionally, lyocell is biodegradable under the right conditions (industrial composting). However, like all fabrics, lyocell production has some environmental impact. Ongoing research aims to further minimize these effects. So, while lyocell is generally a more sustainable choice, maintaining a realistic perspective is important.

Troubleshooting: Wrinkles and Shrinkage

Wrinkles are easily addressed with steaming or low-heat ironing. Unshrinking lyocell, however, is more challenging. Soaking the shrunken garment in lukewarm water with a bit of hair conditioner might relax the fibers, allowing you to gently reshape it. Success isn’t guaranteed, reinforcing the importance of preventative care.

Tips for Keeping Lyocell Looking Its Best

  • The Damp Towel Trick: Washing your lyocell with a damp towel can help reduce friction and tangling, which can contribute to shrinkage.

  • Check the Care Label: Always consult the care label on your specific garment, as fabric blends and manufacturing processes can influence care requirements.

By following these guidelines and treating your lyocell with care, you can enjoy its softness and drape for years to come. While research on fabric care is ongoing, these tips represent current best practices. Do you have any lyocell care tips to share? Let us know in the comments!
