At Thai Son S.P, we specialize in knit fabrics made with Filagen, a functional yarn that blends marine collagen fiber with viscose and other eco-friendly materials. As one of the trusted knitted fabric manufacturers in Vietnam, we supply soft, sustainable fabrics that combine wellness and performance.
What is Filagen?
Filagen is a patented collagen fiber developed from marine collagen peptides. It is blended with biodegradable yarns such as viscose or modal to create a new category of filagen fabric that is both gentle on skin and kind to the planet.
This advanced combination of collagen and fiber offers luxurious softness, excellent moisture retention, and natural odor resistance, which makes it ideal for skin-contact garments.
How Filagen® Collagen Fiber is Made
Filagen® collagen fiber is created through an innovative process that combines collagen and fiber science. The collagen is sustainably recovered from fish skin using gentle enzymatic methods that preserve its bioactivity. This marine-sourced collagen is then blended with a natural cellulose base to form a collagen-enriched viscous solution. Through wet spinning technology, the mixture is transformed into soft, breathable Filagen® fibers. These fibers are then knit or woven into Filagen® fabric, a material that offers skin hydration, odor control, and next-to-skin comfort. The result is a unique fusion of collagen and fiber that elevates both performance and wellness.

Key Features of Filagen Fabric
✅ Skin Moisturizing – Marine collagen peptides help preserve the skin’s natural hydration.
✅ Odor Control – Collagen prevents bacterial buildup, keeping the fabric fresher.
✅ UV Protection – Natural resistance to UV rays provides extra skin care.
✅ Eco-Friendly – Biodegradable and responsibly sourced.

Sustainability & End-of-Life Benefits
Filagen fabric is not only skin-friendly but also eco-conscious. It is made by blending marine collagen with biodegradable fibers such as Modal and viscose. Unlike petroleum-based synthetics, Filagen fabrics naturally decompose at the end of their lifecycle – helping reduce textile waste.
If your brand is committed to responsible sourcing and circular design, Filagen is a material that supports your environmental goals. It is ideal for collections that focus on wellness and sustainability – right from fiber to finish.
