Tout savoir sur les membranes techniques

Everything you need to know about technical membranes

Introduction

Waterproof and breathable technical clothing like VEST PARIS is essential for those seeking comfort and protection from the elements. Whether you're an outdoor enthusiast, an athlete, or someone who simply likes to be prepared for any weather condition, understanding the technology behind these garments can help you make informed choices.

In this article, we will explore in detail the technology, performance and use of waterproof and breathable technical membranes.

Technical membrane technology

A technical membrane is an ultra-thin layer of material that is integrated into clothing via lamination to make it waterproof while allowing moisture from the inside to escape. The bonding of the membrane to the outer fabric is called lamination.

This technology is based on materials such as polytetrafluoroethylene (PTFE) and polyurethane (PU).

How a technical membrane works

The engineered membrane works by blocking water droplets from the outside thanks to its microscopic pores, which are small enough to prevent water from penetrating.

However, these pores are large enough to allow water vapor, produced by perspiration, to escape. This creates a perfect balance between waterproofing and breathability.

The most famous membranes

There are dozens of membranes on the market, each one equally efficient. At VEST, for example, we use Majocchi and Loro Piana membranes. A manufacturer's reputation doesn't necessarily mean that its membranes are more efficient; however, here are three well-known membrane brands.

  1. Gore-Tex : Probably the most well-known membrane, Gore-Tex is famous for its durability and exceptional performance in extreme conditions.
  2. eVent : Known for its superior breathability, eVent allows for rapid evacuation of water vapor, ideal for intense activities.
  3. SympaTex : An ecological membrane that offers excellent waterproofing and good breathability while being recyclable.

The impermeability of technical membranes

The impermeability of a membrane is often measured in millimeters of water column (mmH2O). A membrane with a value of 10,000 mmH2O, for example, can withstand a water column of 10,000 mm before water begins to penetrate.

Garments with high-quality technical membranes can reach values ​​of 20,000 mmH2O or more, providing superior protection even in heavy rain.

Breathability of technical membranes

Breathability is measured by the amount of water vapor that can pass through the membrane in 24 hours (g/m²/24h). Higher values ​​indicate better moisture wicking.

High-end membranes can reach values ​​of 20,000 g/m²/24h, ensuring that you stay dry even during intense physical activities. Those used by VEST have a value of 15,000 g/m²/24h.

Their durability

Durability is a crucial aspect of technical membranes. Treatments such as DWR (Durable Water Repellent) are often applied to improve the membrane's performance and extend its lifespan. These treatments help repel water, allowing drops to bead and roll off the surface of the garment.

Use of Technical Membranes

Outdoor clothing

Technical membranes are commonly used in jackets, pants, and other outdoor clothing. They are ideal for activities such as hiking, mountaineering, and skiing, where weather protection and temperature regulation are crucial.

Urban clothing

Waterproof and breathable membranes are also popular in urban clothing. Coats and jackets featuring these technologies help keep you dry and comfortable during daily city commutes, while offering a modern and functional style.

Sportswear

Athletes and sports enthusiasts benefit greatly from technical membranes. Whether for running, cycling, or other physical activities, these garments enable optimal performance by effectively wicking away sweat while protecting against the elements.

Professional clothing

Professionals who work in harsh weather conditions, such as construction workers or emergency personnel, use clothing with technical membranes to stay protected and comfortable while they work.

Conclusion

Waterproof and breathable technical membranes have revolutionized the world of technical clothing, offering unparalleled protection and comfort. Understanding the technology behind these membranes, their waterproofing and breathability performance, and their various uses can help you choose the best clothing for your specific needs.

Whether you're in the great outdoors, an urban jungle, or on a construction site, clothing with technical membranes ensures you stay dry and comfortable, ready to face any weather condition.
