Functional Textiles

Waterproof

Breathable.
Uncompromised.

NASK nanofiber membranes transform ordinary fabrics into multi-functional textiles — blocking liquid water under pressure while letting perspiration escape freely, with antibacterial, thermal, and anti-odor properties built into the fiber itself.

Core Features

NASK nanofiber technology transforms ordinary fabrics into high‑performance functional textiles.
By incorporating advanced functional additives into the nanofiber structure, we achieve:

Enhance the water proof function on the textile without compromise on breathability

The nanofiber offer a high density layer of nanofiber, which capable to block the water under pressure. And due to it high porosity, only water vapor can pass through and the layer will effectively block the water droplet

Anti-Bacterial Functionality

We functionalize nanofiber with our cutting-edge formulation, making nanofiber attract bacterial and inhibit growth. The high surface to volume ratio nanofiber maximizes contact with bacteria, achieving high efficiency of antibacterial function

Thermal regulation

Integrated phase-change materials (PCMs) in our nanofibers enable dynamic temperature control. These materials absorb, store, and release thermal energy, buffering the wearer against temperature fluctuations for enhanced comfort.

Odor control

Inhibit bacteria that cause odors, and hence keep products smelling fresher for longer

Enhance durability

Extend the life of textiles by reducing the need for frequent washing and preventing microbial degradation

Conventional Technologies to Manufacture Functional Fabrics

Microporous Coatings or Membranes

  • Made of expanded polytetrafluoroethylene (ePTFE) or polyurethane (PU)
  • Inhibit water penetration using surface tension
  • Allow penetration of water vapor due to the presence of micropores
  • Top breathability in the current market
  • High manufacturing cost

Continuous Hydrophilic Coatings or Membranes

  • Made of hydrophilic material such as polyurethane (PU)
  • Move vapor away by molecular wicking
  • Non-porous and less breathable than microporous membranes
  • Relatively low manufacturing cost

Distinctive Properties

Five features

Feature Advantage
Small pore size Effectively block water droplets while allowing water vapor molecules to pass throughh
Hydrophobic material Effectively repel water droplet and prevent water penetration
High porosity Allow water vapor molecules to pass through the membrane efficiently.
High specific surface area Allow extra functions such as killing bacteria on the spot
PFAS-free Environmental-friendly
Dual-Mode Breathability

Physical + Chemical transfer.

  • Physical mode
  • Water vapor molecules pass directly through nanofiber pores.
  • Chemical mode
  • Vapor transferred by physicochemical process across the fiber surface.
