Lyocell Embroidery Thread

Lyocell, like rayon, is made of cellulose fibers originating from wood pulp. In addition to being sourced from sustainably-managed forests, it is manufactured in an environmentally-friendly manufacturing process using a “closed-loop” system where almost all solvents, water and emissions are recovered and reused. Lyocell fibers are particularly smooth and silky, even while being strong and durable and highly absorbent, which means it readily takes and retains dye colors well.  Its silky softness and moisture-wicking properties makes Lyocell ideal for applications where gentleness against the skin is necessary, as well as for items that require resistance to wear and tear.  It runs easily through the embroidery machine, and stitches out with a somewhat soft, subtle finish.  It feels velvety to the touch, won’t irritate the skin, and pairs naturally with organic and eco-friendly clothing.

Best Uses & Applications

Lyocell threads are extremely versatile, making them ideal for a wide variety of embroidery applications:

  • Skin-facing clothing: Lyocell is soft and irritation-free against the skin, ideal for baby wear, undergarments, athleisure and activewear
  • Home Textiles: Bed linens, towels and decorative fabrics
  •  Accessories: High-quality fashion items like scarves, hats, and fashion bags
  • Sustainable Garments: Lyocell is the perfect choice to pair with environmentally-conscious clothing.

Pros & Cons

Lyocell thread has many advantages, and a few disadvantages:

Pros

  • Comfort: The softness and moisture-wicking properties of Lyocell make it ideal for clothing and accessories that need to be comfortable and gentle against the skin.
  •  High performance: Long-lasting and maintains its color and look over a long period of time.
  • Versatility: Can be used on a wide range of textiles, from delicate embroidery to robust stitching on heavier applications.
  •  Environmentally friendly: The sustainable, closed-loop manufacturing process satisfies the demands of environmentally-conscious embroiderers.

Cons

  • Care: Lyocell thread is durable, but should be washed on gentle cycle and high heat drying should be avoided.
  •  Cost: Lyocell may be slightly more expensive than conventional embroidery thread due to its sustainable production process.

Dos and Don’ts

To make the most of Lyocell embroidery threads, follow these tips:

Dos

  • Store properly: Prevent Lyocell from being exposed to long time direct sunlight to maintain color and thread quality. Keep cones free from dust and humidity by storing in a closed container.
  • Adjust tension: Start Lyocell thread with a light tension and adjust up as necessary. Experiment with  tension range to find the perfect setting on your machine. 
  • Keep your machine clean: Lyocell can create slightly more lint than synthetic threads as it runs through your machine. A quick spritz with canned air can clear any fibers from the needle and rotary hook area and maintain smooth machine operation.

Don'ts

  • Expose to high heat: Care instructions for Lyocell generally recommend cold or cool water wash and air-dry or low-heat drying. High-heat conditions, especially when wet, can compromise the integrity of Lyocell. 
  • Neglect a test-run: To ensure your design and fabric pair with Lyocell thread, be sure to do a test run to make sure your embroidery looks as expected. Pre-washed fabrics and garments are recommended when working with Lyocell.

Frequently Asked Questions (FAQ)

Q: What is Lyocell embroidery thread made of?

A: Lyocell embroidery thread is made from cellulose fibers derived from wood pulp, typically from renewable forests like eucalyptus, beech, or birch and created in a sustainable manufacturing process that recycles nearly all of the solvents and water used.  

Q: Is Lyocell suitable for all types of fabrics?

A: Lyocell thread works well with most natural fabrics such as cotton, linen, and bamboo. It can also be used on synthetic fabrics, but testing on a small piece is recommended to ensure compatibility and desired results.

Q: What needle size should I use with Lyocell thread?

A:  The average-size needle for 40-weight Lyocell, such as 75/11, is usually recommended. As with all threads, the specific needle size may vary depending on the thread weight being used.

Q: Does Lyocell thread have good colorfastness?

A: Yes, Lyocell thread typically has good dye retention and colorfastness. However, it is advisable to test for colorfastness, especially if the embroidered item will be exposed to water or frequent washing.

Q: Can Lyocell thread be used for both decorative and functional embroidery?

A: Yes, Lyocell thread is strong and durable, making it suitable for both decorative and functional embroidery. Its silky texture and vibrant colors make it ideal for decorative designs, while its strength ensures it holds up well in functional applications.

Q: How do I store Lyocell embroidery thread?

A: Store lyocell thread in a cool, dry place away from direct sunlight to prevent degradation. Keeping it in a sealed container helps protect it from dust and humidity.

Conclusion

Lyocell threads are one of the most sustainable and eco-responsible threads in the decorated apparel industry.  They are also soft and supple with an organic look and feel and are unlikely to cause skin irritation.  This makes them ideal for undergarments, intimates, infant wear and leisure or exercise garments.  The vibrant colors and subtle finish create an organic look that works well with clothing, accessories and home decor.  When embroidered and cared for according to recommended specifications, Lyocell keeps its bright color, strength and softness for as long as the garment or textile on which it’s used.
