How non-woven fabric become water resistance
Non-woven fabrics are naturally quite absorbent due to their structure of randomly arranged fibers. To make them water resistant, several treatment methods can be applied:
Common Water Resistance Treatments
- Chemical Treatments
- Application of fluorochemicals (like fluorocarbons)
- Silicone-based water repellent coatings
- Wax emulsions or paraffin treatments
- Lamination Processes
- Applying a thin polyethylene or polypropylene film
- Bonding with waterproof membranes
- Spray Coating
- Applying hydrophobic polymers through spray application
- Often used for medical and protective garments
- Melt-blown Technology
- Creating inherently water-resistant layers during manufacturing
- Often used in multi-layer non-woven products
The level of water resistance achieved can vary from water-repellent (water beads up and rolls off) to fully waterproof (completely prevents water penetration), depending on the treatment intensity and intended application.
