What Is SEACELL Fabric? The Seaweed-Infused Textile Redefining Sustainable Fashion
Share
SEACELL fabric is a cellulosic textile made from a blend of wood pulp and seaweed, harvested sustainably from the fjords of Iceland. It combines the softness of natural fibers with the nourishing properties of algae, releasing vitamins and minerals into the skin as you wear it. If you've ever wondered why some garments feel almost therapeutic against your body, chances are they were made with this quiet marvel of marine innovation.
At Tabinotabi, we've built our Venice atelier around fabrics like this—materials that respect the sea while celebrating the body. SEACELL isn't a marketing gimmick. It's a genuine breakthrough in textile science, and it deserves a proper introduction.
What Is SEACELL Fabric Made Of?
SEACELL is a type of lyocell, produced through a closed-loop process similar to how eucalyptus fibers become TENCEL™. Wood pulp is dissolved in a non-toxic solvent, then infused with brown seaweed—typically Ascophyllum nodosum, harvested from the pristine waters of Iceland. The mixture is spun into fine, silky fibers.
The seaweed is never over-harvested. It regrows naturally within weeks, making the entire supply chain renewable by design. This is a sharp contrast to fabrics that strip resources without giving anything back.
Once woven into fabric, SEACELL retains microscopic amounts of seaweed embedded in the fiber itself. As you move and sweat lightly, these marine nutrients—rich in vitamin E, magnesium, calcium, and amino acids—are gradually released onto the skin.
The Benefits of SEACELL Fabric
SEACELL isn't just an eco-story. It performs beautifully, too.
- Skin-nourishing: The seaweed content delivers antioxidants and minerals directly to the skin, making it ideal for sensitive or reactive skin types.
- Naturally soft: The fiber has a smooth, almost silky hand-feel, similar to modal or fine cotton.
- Breathable and moisture-wicking: It regulates temperature well, keeping you cool in summer and cozy in cooler months.
- Biodegradable: As a cellulosic fiber, SEACELL breaks down naturally at the end of its life, leaving no microplastic residue.
- Low environmental impact: The closed-loop production process reuses water and solvents, drastically reducing waste compared to conventional textile manufacturing.
These qualities make SEACELL especially suited to loungewear, intimates, and everyday essentials—pieces meant to be worn against bare skin, day after day.
SEACELL vs Cotton vs Polyester: A Quick Comparison
To understand why SEACELL stands apart, it helps to see it side by side with the two most common fabrics on the market.
| Feature | SEACELL | Cotton | Polyester |
|---|---|---|---|
| Raw material | Wood pulp + seaweed | Cotton plant fiber | Petroleum-based plastic |
| Water usage | Low (closed-loop process) | Very high | Low, but polluting |
| Biodegradable | Yes | Yes | No |
| Skin benefits | Vitamins & minerals released on skin | None | None |
| Breathability | Excellent | Good | Poor |
| Microplastic shedding | None | None | Yes |
| Softness | Very soft, silky | Soft, can roughen with age | Synthetic feel |
The takeaway is simple: SEACELL offers the comfort of natural cotton with added skin benefits, and none of the environmental baggage that comes with polyester.
Why Tabinotabi Chooses SEACELL for Its Collections
Venice taught us to respect water. Our lagoon city has lived alongside the sea for over a thousand years, and that relationship shapes everything we design. When we discovered SEACELL, it felt like a natural extension of our philosophy—a fabric literally born from the ocean, worn close to the body, gentle on both skin and planet.
Every piece in our collections that uses SEACELL is chosen for a reason: it feels indulgent, but it's responsibly made. We pair it with eucalyptus-based TENCEL™ and other low-impact fibers to create garments that feel like a second skin, not a compromise.

How to Care for SEACELL Fabric
SEACELL is low-maintenance but rewards a little care:
- Wash in cold or lukewarm water on a gentle cycle.
- Use mild, phosphate-free detergent to preserve the fiber's natural properties.
- Avoid high heat when drying—air dry flat whenever possible.
- Skip fabric softener; SEACELL is already naturally soft.
- Iron on low heat if needed, ideally with a damp cloth barrier.
Treated well, SEACELL garments retain their softness and skin-nourishing qualities wash after wash.
Is SEACELL Fabric Worth It?
If you're building a wardrobe around sustainability and comfort, SEACELL checks both boxes without asking you to sacrifice either. It's a fabric that tells a story—of Icelandic fjords, closed-loop innovation, and skin that deserves better than synthetic fibers.
For eco-conscious women who care about what touches their skin and where it comes from, SEACELL isn't just a trend. It's a quiet, thoughtful choice—one we're proud to weave into every collection we create.
