Textiles have always covered our bodies, but what if they could also power the things around us? Heliotex (formerly known as Suntex), from designer Pauline van Dongen, is a challenge to what people think fabric can do.
Heliotex is basically a way to combine organic photovoltaics with lightweight, flexible fabrics. The result is sunshades and canopies that generate energy and look good at the same time. These fabrics move, fold, and breathe with their surroundings, unlike rigid solar panels. They think of renewable energy not as something that needs to be hidden away, but as something that is beautiful, soft, and fits in perfectly with the rest of the world.
“We focus on outdoor applications like textile facades, festival tents, and shade structures… Of course, we also foresee indoor applications like curtains and sun shading.”
Pauline van Dongen
The fact that Simon Angel included the project in this season’s SUSTAINABLE INNOVATIONS forum puts it in a bigger story: textiles are no longer passive. They are tools for making big changes in the system. Heliotex shows how fabrics can go beyond traditional categories by working at the intersection of design, architecture, and energy. It is similar to Wetlands Matters and Plantfur.
The effects of van Dongen’s work on the fashion and textile industries will be huge. The textile industry can grow if textiles can collect energy. Sustainability stops being about doing less harm and starts being about giving more value, like comfort, beauty, and clean energy all at once.
The lesson is practical but lofty: sustainability should feel like a part of everyday life, not something that is added on. Heliotex shows that renewable energy can be touchable, welcoming, and even luxurious. This is a call for people who work in fashion and textiles to think of fabrics not just as things we wear, but also as the buildings we live in.

What matters is how the textile responds: how it regulates volume, distributes pressure, and transitions from flat to three-dimensional states. Process transparency is embedded in the methodology itself.

MATERIA FUTURA – SUSTAINABLE INNOVATIONS
18. January 2026
Materia Futura is not proposing a new bio-material category, nor a finished commercial textile. What distinguishes the project is its design-led investigation into the emotional and aesthetic dimensions of bio-based materials, an area often sidelined in sustainability discourse.
THREADED PROTOCOLS – SUSTAINABLE INNOVATIONS
17. January 2026
Threaded Protocols is not a textile innovation in the commercial sense, nor a digital tool disguised as craft. What makes the work distinct is its material investigation into how computational logic originates in textile practice and what is lost when those logics are abstracted into opaque technological systems.
MARIE VILAY – SUSTAINABLE INNOVATIONS
16. January 2026
Marie Vilay does not present a new fabric or production technique. What distinguishes her work is a method of reading and translating textile knowledge across cultures, systems, and moments of transition.
