TPU Elastic Non-Woven for Waterproof Clothing: Rain Gear and Outdoor Apparel
How TPU elastic non-woven membranes enable waterproof, breathable outdoor and rainwear
Waterproof clothing needs to block rain while letting sweat escape. TPU elastic non-woven for waterproof clothing is used as the waterproof/breathable membrane in high-performance rain gear and outdoor apparel.
Here's how TPU membranes perform in apparel applications.
Waterproof/Breathable Membrane Requirements
A membrane for waterproof clothing must balance:
- Waterproofness: 10,000-30,000 mm hydrostatic head (depends on activity)
- Breathability (MVTR): 8,000-20,000 g/m²/24h (higher for high-exertion activities)
- Flexibility: Must move with the wearer — no cracking or delamination
- Durability: Withstand washing, abrasion, and UV exposure
TPU vs. ePTFE (Gore-Tex®) Membranes
| Property | ePTFE (Gore-Tex type) | TPU Elastic Non-Woven |
|---|---|---|
| Waterproofness | Excellent (30,000+ mm) | Very good (10,000-30,000 mm) |
| Breathability | Excellent | Very good |
| Flexibility | Good | Excellent (elastic) |
| Cost | High | Lower |
| Oil resistance | Poor (pores can clog) | Good |
TPU doesn't match ePTFE's extreme performance, but it covers 90% of use cases at a much lower price point.
Garment Construction with TPU Membrane
3-layer construction: Outer fabric + TPU membrane + inner lining — all laminated together. Most durable, used for serious outdoor gear.
2.5-layer construction: Outer fabric + TPU membrane + printed protective layer (no separate lining). Lighter weight, used for ultralight rain shells.
2-layer construction: Outer fabric + TPU membrane, with a separate lining. Less expensive, used for urban rainwear.
DWR (Durable Water Repellent) note: The outer fabric needs DWR treatment to prevent "wetting out" — when the outer fabric gets saturated, breathability drops even if the TPU membrane is fine. TPU membranes perform best when the face fabric stays dry.
Applications
- Hiking/backpacking rainwear: Jackets and pants needing 15,000+ mm waterproofness and 10,000+ MVTR
- Ski/snowboard gear: Needs higher MVTR due to high exertion; TPUelasticity is a plus for movement
- Urban/commuter rainwear: Lower performance requirements; TPU offers a cost-effective solution
- Golf/tennis outerwear: Stretch is important — TPU's elasticity is a diferentiator vs. PTFE
