Nano- and Biotechnologies for Functional Fibrous Products

Adding antimicrobial, protective and responsive functions to fibers using nano- and biotechnologies.

Nanotechnology and biotechnology can give ordinary fibers extraordinary properties: antimicrobial action, water and stain repellency, UV protection, conductivity or controlled release. We help companies apply these technologies to improve and add functionality to fibrous products.

Our focus is practical: which functional treatments are durable, safe, cost-effective and compatible with your existing manufacturing.

Common problems we're called in to solve

  • A functional finish washes out after a few laundering cycles.
  • Regulatory pressure on PFAS or certain biocides requires a replacement chemistry.
  • Nanoparticle additives cause processing problems or inconsistent results.
  • Marketing claims about function need technical substantiation.

Our approach

  1. 1Screen nano- and bio-based options against performance, durability and regulatory requirements.
  2. 2Advise on application methods: in-fiber, coating, padding or grafting.
  3. 3Design durability and wash-fastness testing.
  4. 4Support claim substantiation and documentation.

Outcomes and benefits

  • Functional products whose benefits last.
  • Chemistries aligned with tightening regulations.
  • Defensible performance claims.

Serving Pleasant Hill and the Bay Area

California's restrictions on PFAS in textiles have made functional-finish reformulation urgent for brands across the Bay Area and the state, and we help them make that transition with confidence.

Frequently asked questions

Are there effective PFAS-free water repellents?

Yes, several non-fluorinated chemistries perform well for many applications, though oil repellency is more challenging. We help match the option to the use case.

Is nanotechnology safe in textiles?

Safety depends on the material, its binding to the fiber and potential release. We evaluate these factors as part of any recommendation.

Can functional finishes be added to existing products?

Often yes, through finishing or coating steps, without redesigning the base fabric.
