How to Store Tencel A100 Yarn: A Complete Guide

Tencel A100 yarn is renowned for its strength, softness, and eco-friendly production. While it's naturally durable and resistant to many environmental factors, proper storage is essential to preserve its quality, color vibrancy, and fiber integrity over time. Whether you're a professional knitter, crocheter, or hobbyist, following best practices for storing Tencel A100 yarn ensures it remains in excellent condition for your next project.

Quick Tip: Tencel A100 is a lyocell fiber made from sustainably sourced wood pulp. While it resists mold, mildew, and UV damage better than many natural fibers, it still benefits from thoughtful storage to prevent long-term degradation.

Best Practices for Storing Tencel A100 Yarn

1. Maintain a Dry, Cool Environment

   Moisture is one of the biggest threats to yarn storage—even for Tencel, which has natural resistance to mold and mildew. Prolonged exposure to humidity can weaken the fibers, cause discoloration, and lead to brittleness over time.

   Store your Tencel A100 yarn in a cool, dry place with consistent temperature and low humidity. Ideal conditions include a climate-controlled room with minimal temperature fluctuations.

   To further protect against moisture, consider placing silica gel sachets in your storage area. These small, non-toxic packets absorb excess humidity and help maintain a dry microclimate around your yarn. Replace or recharge them periodically for continued effectiveness.

2. Protect from Direct Sunlight and UV Exposure

   While Tencel is more UV-resistant than cotton or wool, prolonged exposure to direct sunlight can still cause fading and gradual fiber degradation. UV rays break down the molecular structure of the fiber, leading to loss of strength and dulling of colors.

   Always store your yarn in a shaded area—away from windows, skylights, or outdoor-facing shelves. For added protection, use opaque containers, fabric yarn bags, or storage boxes that block light completely.

   This also helps prevent dust accumulation and keeps your yarn clean and ready to use.

3. Use Breathable Storage Containers

   Proper airflow is crucial for preventing trapped moisture and heat buildup. Choose storage solutions that allow your yarn to "breathe," such as:

   • Woven baskets with ventilation gaps
   • Mesh or cotton yarn storage bags
   • Cardboard boxes with small ventilation holes

   Avoid airtight plastic bins or sealed plastic bags unless they include desiccants. In humid environments, sealed plastic can trap condensation, creating a damp environment where Tencel fibers absorb moisture—increasing the risk of mold and mildew despite its natural resistance.

4. Prevent Pest Infestations

   Tencel A100 is not a food source for moths or carpet beetles, making it inherently pest-resistant compared to animal-based fibers like wool. However, pests may still nest in or around yarn storage if other materials (like paper or mixed-fiber yarns) are present.

   To deter insects naturally, place lavender sachets, cedar blocks, or dried rosemary near your storage area. These emit scents that repel common fabric pests without harsh chemicals.

   Regularly inspect your storage space for signs of pests—such as webbing, droppings, or cocoons—and clean containers periodically to maintain a pest-free environment.

5. Organize by Fiber Type and Color

   Keeping your Tencel A100 yarn organized prevents confusion and protects the quality of your stash. Mixing different fiber types can lead to unintended blending during projects or accidental dye transfer if stored while damp.

   Sort your yarn by:

   • Fiber content – Keep Tencel separate from wool, cotton, or acrylic blends
   • Color family – Group light, dark, and variegated skeins to prevent color bleeding if moisture occurs
   • Weight or gauge – Categorize by DK, worsted, bulky, etc., for easier project planning

   Consider using labeled bins, clear drawer organizers, or a digital inventory app to track your collection and find what you need quickly.

Storage Factor	Recommended Practice	Risks of Improper Storage	Recommended Tools
Humidity	Store in dry environment with silica gel	Fiber weakening, mold risk, color fading	Silica gel packs, hygrometer
Light Exposure	Use opaque, UV-blocking containers	Color fading, reduced fiber strength	Cardboard boxes, fabric bags
Ventilation	Breathable containers with airflow	Moisture trapping, musty odors	Mesh bags, woven baskets
Pest Control	Natural repellents and regular checks	Nesting or contamination from nearby fibers	Cedar blocks, lavender sachets
Organization	Sort by fiber, color, and weight	Mix-ups, dye transfer, inefficient use	Label maker, storage bins, inventory list

Pro Tip: Before storing leftover yarn from a project, gently hand-wash and dry it to remove oils, dirt, or odors. This ensures it remains fresh and ready for future use without compromising the rest of your stash.

Additional Storage Recommendations

• Rotate your yarn stash occasionally to ensure even environmental exposure
• Avoid storing yarn in attics, basements, or garages where temperature and humidity fluctuate
• Keep yarn away from heating vents, radiators, or air conditioning units
• Re-wrap loose skeins into cakes or hanks to prevent tangling during storage
• Check stored yarn every few months for changes in texture, smell, or appearance

By following these guidelines, you’ll extend the lifespan of your Tencel A100 yarn and maintain its luxurious feel and vibrant colors for years to come. Proper storage not only protects your investment but also enhances your crafting experience by ensuring your materials are always in top condition when inspiration strikes.

Frequently Asked Questions About Tencel Yarn

Q1: Is Tencel yarn good for sensitive skin?

Yes, Tencel yarn is an excellent choice for individuals with sensitive skin. Its fibers are naturally smooth and soft, lacking the rough edges or protrusions that can cause irritation. This makes it particularly gentle on delicate or allergy-prone skin.

One of the key benefits of Tencel is its long, strong fiber structure, which minimizes pilling and reduces the likelihood of itching. Additionally, Tencel has superior moisture-wicking properties—it absorbs and releases moisture quickly, preventing dampness from being trapped against the skin. This breathability helps regulate temperature, keeping the wearer cool and comfortable, which is especially beneficial in warm climates or for those prone to overheating.

Because of these qualities, Tencel is widely used in baby clothing, undergarments, sleepwear, and medical textiles where comfort and skin compatibility are essential.

Q2: What are the downsides of Tencel?

While Tencel offers many advantages, there are a few potential drawbacks to consider:

• Higher Cost: Tencel is generally more expensive than conventional cotton or synthetic fibers. This is due to its sustainable production process, specialized manufacturing techniques, and the use of certified wood pulp from responsibly managed forests.
• Wrinkling Tendency: Compared to synthetic fabrics like polyester, Tencel has a greater tendency to wrinkle. While this doesn’t affect performance, it may require more care during wear and laundering to maintain a crisp appearance.
• Reduced Strength When Wet: Like many natural-based fibers, Tencel loses some of its tensile strength when saturated with water. This means garments or yarns should be handled gently when wet to avoid stretching or damage during washing or blocking.
• Care Requirements: Although durable, Tencel performs best with gentle washing (preferably hand wash or delicate cycle) and air drying to preserve its softness and shape over time.

Despite these limitations, many users find that the comfort, sustainability, and aesthetic appeal of Tencel outweigh its minor drawbacks.

Q3: What is the difference between Tencel and Lyocell?

The terms "Tencel" and "Lyocell" are often used interchangeably, but there is an important distinction:

Aspect	Lyocell	Tencel
Definition	A type of rayon made from dissolved wood pulp using an organic solvent.	A branded version of Lyocell produced exclusively by the Austrian company Lenzing AG.
Production Process	General closed-loop process; efficiency varies by manufacturer.	Uses a proprietary, highly efficient closed-loop system that recycles over 99% of solvents and water.
Performance	Soft and breathable, but quality may vary depending on production standards.	Typically stronger, smoother, and more consistent due to advanced processing techniques.
Sustainability	Eco-friendly compared to traditional rayon, but not standardized.	Certified as one of the most sustainable fiber options, with FSC or PEFC-certified wood sources and low environmental impact.

In short, all Tencel is Lyocell, but not all Lyocell is Tencel. Think of Tencel as the premium, high-performance variant of Lyocell, backed by rigorous environmental standards and innovation.

Q4: Can Tencel be stored in plastic containers?

Tencel yarn can technically be stored in plastic containers, but it's generally recommended to opt for breathable storage solutions to preserve its quality over time.

Because Tencel is derived from natural cellulose (wood pulp), it is sensitive to prolonged exposure to trapped moisture, which can lead to mildew, odor, or fiber degradation. Airtight plastic bins may create a humid microclimate, especially in damp environments or during seasonal changes.

Best Practices for Storing Tencel Yarn:

• Use Cotton Bags or Cardboard Boxes: These allow airflow and help prevent moisture buildup.
• If Using Plastic: Choose containers with ventilation holes or leave the lid slightly ajar. Include silica gel packets to absorb excess humidity.
• Avoid Direct Sunlight and Heat: Store in a cool, dry, dark place to prevent fiber weakening and color fading.
• Keep Away from Pests: While Tencel is not a protein fiber (so not attractive to moths), storing it with cedar blocks or lavender sachets can deter other pests and add a pleasant scent.

Proper storage ensures your Tencel yarn remains soft, vibrant, and ready for crafting whenever inspiration strikes.
