How Coffee Grounds Are Turned Into Activewear Fabrics

When you toss out used coffee grounds, you’re likely not thinking about next season’s workout gear. But one Taiwanese company turned that waste into a global textile revolution—creating fabrics that pull double duty: odor control and moisture wicking, all from what was once discarded.

Coffee grounds, combined with recycled plastic bottles, now make up performance fabrics used by brands like Victoria’s Secret, Nike, and The North Face. Just three cups of coffee and twelve half bottles can produce one coffee-fabric jacket—with proven deodorizing and thermal benefits.

The Birth of Coffee Fabric

In 2005, David Chen, chairman of Taiwan’s Singtex Industrial Co., overheard his wife joke that coffee grounds could eliminate post-workout body odor. That offhand comment sparked a decade-long mission to turn coffee waste into functional textiles. At the time, Taiwan’s textile industry was struggling against cheaper labor markets in China and Southeast Asia. Rather than compete on price, Chen pivoted to high-value synthetic materials—and eventually, coffee.

Chen’s team spent two years developing the first eight iterations of what would become S.Café, their proprietary coffee yarn. Early prototypes had a pleasant coffee scent—but after months of wear, testers reported an unpleasant lingering smell. The issue? Residual coffee oils mixing with sweat. Chen solved it by refining the coffee grounds down to 400 nanometers and removing all oils before blending the grounds into yarn made from recycled PET bottles. By 2008, the final formula delivered effective odor control and moisture management—and earned multiple international patents.

Performance Meets Sustainability

S.Café coffee yarn isn’t just functional—it’s sustainable. Each jacket requires just three cups of coffee grounds and 12 half plastic bottles. The production process avoids harsh chemicals like acetone, uses low-temperature, high-pressure oil extraction (cutting carbon emissions by 80% compared to traditional methods), and relies on natural gas for heating instead of coal—despite a fourfold fuel cost increase. This approach reduces CO₂ emissions by 1,300 to 2,750 tons annually.

The fabric also meets the rigorous Bluesign Standard, the textile industry’s strictest environmental certification. While coffee yarn costs 20–30% more to produce, adding just 35% coffee yarn to a garment delivers full deodorizing and thermal benefits without a major price hike.

Beyond Coffee Yarn: Other Coffee Waste Innovations

Singtex has expanded its coffee waste product line far beyond yarn. For Victoria’s Secret, the company supplied AIRNEST foam, which replaces 25% of traditional petroleum-based PU foam with coffee grounds—offering the same cushioning with added odor resistance. The firm also developed a coffee-oil-based waterproof membrane that’s thin, flexible, and highly breathable, allowing sweat vapor to escape while repelling water. In 2013, they introduced coffee-ground-printed fabric treatments for moisture control and quick drying.

These innovations aren’t limited to clothing. Extracted coffee oil is also repurposed into everyday chemical products. Singtex’s coffee-based materials are now used by over 100 global brands, including The North Face, New Balance, Timberland, Hugo Boss, Li-Ning, and even Starbucks’ barista uniforms. The company’s patented technologies have attracted partnerships with Nike and The North Face, both of which subject suppliers to rigorous sustainability scoring—including pollution, energy use, and environmental impact metrics.

Frequently Asked Questions

What is S.Café coffee yarn?

S.Café is a patented textile yarn made from recycled coffee grounds and plastic bottles. Developed by Taiwan’s Singtex, it offers odor control, moisture wicking, and UV protection. The coffee grounds are finely ground to 400 nanometers and de-oiled before being blended into yarn spun from recycled PET.

How much coffee is needed to make a coffee fabric garment?

It takes three cups of coffee grounds and twelve half plastic bottles to produce one coffee-fabric jacket. This combination creates a functional, sustainable material used in activewear and outerwear.

Does coffee fabric really reduce odor?

Yes. S.Café fabric actively reduces odor by absorbing sweat and neutralizing odors. Early issues with lingering smells were resolved by removing all coffee oils from the grounds before spinning the yarn, ensuring long-term freshness during wear.

What brands use coffee fabric?

Major brands including Victoria’s Secret, Nike, The North Face, Puma, The North Face, Hugo Boss, Li-Ning, Timberland, New Balance, and Starbucks (for staff uniforms) use Singtex’s coffee-based fabrics and materials. The yarn is also found in shoes, bags, and outdoor gear.

Is coffee fabric production environmentally friendly?

Yes. The process avoids harsh chemicals, uses recycled PET bottles, and employs low-temperature oil extraction that cuts carbon emissions by 80%. It is certified under the Bluesign Standard, the textile industry’s most stringent environmental benchmark.

How does coffee fabric compare in cost to regular fabric?

Coffee fabric costs 20–30% more to produce, but only 35% coffee yarn is needed to achieve full functionality. This keeps the overall cost increase modest while delivering significant performance benefits.
