Nibertex closes $7M Series A to scale sustainable textile production

August 12, 2025

Good for the planet and great for you. Here’s Nibertex! They’re manufacturing a PFAS-free, waterproof, and breathable textile membrane to give consumers more sustainable fabric options. 

But it’s more than just sustainability.

  • Now, they just raised a $7M Series A!

Investor check. TNB Aura led the round, while Asian Development Bank, Faircrest Holding, and Foxmont Capital Partners also joined in!

  • They last raised a Pre-Series A earlier this year. 

🧵 In the membrane

Plastics and chemicals in your daily wear? No thank you!

The problem? Most breathable and waterproof clothing items today have PFAS or per- and polyfluoroalkyl substances in them, which has been linked to serious health concerns.

  • PFAS is a synthetic chemical found in rain jackets, activewear, and medical gowns. But it’s also used in food packaging and non-stick cookware to provide water and stain resistance. 

🪡 Where Nibertex comes in

They built a proprietary electrospinning or nanospinning technology and formula that produce PFAS-free membranes designed to blend seamlessly into the textile. 

  • The result? The textile is environmentally friendly, while still being breathable and waterproof.

Background. Founded in 2019, Nibertex’s PFAS-free membranes are ideal for use in performance apparel, healthcare, industrial, and consumer applications. 

👔 What the future holds? 

They’ll use the $$$ to expand their manufacturing capacity, advance their R&D to go beyond apparel, and deepen their market reach.
