In a world where sustainability and comfort are no longer mutually exclusive, Tencel™ Modal has become the fabric of choice for eco-conscious underwear brands. Its silky softness, breathability, and carbon-neutral production make it a top-tier option for those seeking both performance and responsibility.
Tencel™ Modal is derived from renewable beechwood using a closed-loop process that reuses up to 95% of production solvents. This not only reduces environmental impact but also ensures consistency and softness that’s ideal for intimate wear.
For buyers focused on lowering carbon emissions while delivering premium undergarments, the fabric answers two vital questions: Is it comfortable enough for daily wear? And does it meet sustainability standards for the modern market?
What Makes Tencel™ Modal Ideal for Next-to-Skin Comfort?
Tencel™ Modal is widely recognized for its superior handfeel—silkier than cotton, cooler than polyester, and naturally breathable. This makes it a perfect fiber for products worn directly against the skin, like underwear and loungewear.
The smooth fiber surface prevents irritation and maintains comfort even in humid or active conditions, offering second-skin performance with a luxury finish.
Why Is Tencel™ Modal Softer Than Cotton?
Unlike cotton, Tencel™ Modal is manufactured with a finer cross-section and smoother surface, reducing fiber stiffness. The result is a material that drapes better and resists pilling longer.

Does It Maintain Breathability During Use?
Absolutely. Modal fibers are highly breathable due to their natural origin and optimized fiber shape. They absorb moisture 50% better than cotton, making them ideal for underwear and base layers.

How Does Tencel™ Modal Support Carbon-Neutral Production?
One of the most attractive features of Tencel™ Modal is its low carbon footprint. Lenzing Group—the trademark owner—has committed to carbon neutrality across the entire supply chain. The fiber is made using renewable energy, and the closed-loop process ensures water and chemicals are reused efficiently.
This aligns with brands and buyers striving to meet net-zero goals and offers tangible carbon-reduction claims.
What Is the Environmental Impact Compared to Cotton or Rayon?
Tencel™ Modal uses 10–20x less water than conventional cotton and avoids the deforestation often linked to viscose rayon. Its production emits up to 50% less CO₂ compared to fossil-fuel-derived synthetics like polyester.

Is It Certified for Global Carbon-Responsible Supply Chains?
Yes. Tencel™ Modal holds multiple eco-certifications:
- EU Ecolabel
- OEKO-TEX® Standard 100
- PEFC™ (Programme for Endorsement of Forest Certification)
- TÜV Austria OK Biodegradable
Fumao Fabric offers traceability down to the fiber lot, ensuring your garments can carry certified carbon-neutral claims.

What Underwear Products Are Best Made with Tencel™ Modal?
Tencel™ Modal adapts beautifully to various underwear formats due to its high stretch compatibility, durability, and moisture-wicking ability. At Fumao, we’ve seen demand soar for:
- Seamless briefs
- Boxer shorts
- Bralettes
- Bodysuits
- Maternity underwear
- Thermal base layers
Its colorfastness and easy dyeability also mean brands can offer deep tones and vibrant pastels without harsh chemical treatments.
Does It Work with Elastane for Stretch Underwear?
Yes. Modal blends seamlessly with elastane (spandex) for 2-way or 4-way stretch. Fabrics like 95/5 Modal-Spandex or 90/10 Modal-Spandex offer ideal recovery, making them perfect for snug-fitting underwear.

How Durable Is Modal in Repeated Wash Cycles?
Modal holds its strength even after 50+ washes. Unlike rayon, it doesn’t shrink easily and resists pilling—making it a great base for reusable and long-wear underwear collections.
