When heatwaves push temperatures into uncomfortable ranges, the demand for garments that keep workers cool while remaining breathable has never been higher. CELUSA, a pioneer in sustainable apparel, has partnered with the University of South Australia (UniSA) to introduce a lightweight, solar‑reflective fabric engineered for extreme outdoor environments.
How the new material works
The fabric combines a biodegradable polylactic acid (PLA) matrix with boron nitride nanosheets (BNNS). BNNS are known for their exceptional thermal conductivity; by embedding them into the PLA fibers, the material can spread heat across the garment’s surface. This, in turn, enhances radiative cooling, allowing the fabric to shed heat without relying on active electronics.
Solar Reflectance and Breathability
- Reflective capacity: The white, nano‑structured weave reflects about 96 % of incident sunlight, keeping skin temperatures significantly lower than conventional cotton.
- Moisture management: The composite structure pulls sweat away from the skin and releases it into the air, reducing the damp feeling that can lead to heat stress.
- Weight and comfort: Because the material is produced via electrospinning—a scalable, low‑cost process—the final garment remains lightweight and flexible.
Field trials conducted in Adelaide’s high‑temperature zones showed a skin temperature reduction of 2 °C under direct sunlight and 3.8 °C during the night compared to bare skin. Such data underscore the material’s potential for real‑world use.
Applications for outdoor professionals
Construction crews, mining teams, agricultural workers, and emergency responders often face prolonged heat exposure. The new composite fabric offers several safety and comfort advantages for these groups:
- Heat‑stress mitigation: By passively regulating body temperature, the material helps prevent heat exhaustion and heat‑stroke.
- Durability: PLA fibers have a tensile strength comparable to certain synthetics, while the nanostructure resists abrasion better than plain cotton.
- Eco‑friendly credentials: Being primarily biodegradable, the garment aligns with industry push‑back against single‑use plastics and hazardous textiles.
Beyond professional wear, the same technology can be adapted for performance gear, military field uniforms, and even everyday summer clothing in hot climates.
Why sustainability Matters in Cooling Technology
Traditional cooling garments often rely on phase‑change materials or built‑in fans that consume energy and produce waste heat. In contrast, CELUSA’s PLA/BNNS composite achieves passive cooling, meaning it works without electricity or significant resource input. The result is lower environmental impact throughout the product life cycle—from extraction to disposal.
Recycling and Resource Lifecycle
Polylactic acid is derived from renewable plant sources such as corn starch. When the garment’s end of life arrives, PLA can be processed locally into bio‑plastic products, closing the loop. Coupled with the recyclability of the BNNS component, the composite supports circular design.
Cedifying the Deal: From Lab to Market
While the laboratory and field tests validate performance, scaling production introduces new challenges. The production team at UniSA’s Future Industries Institute confirms that the electrospinning setup is industrially scalable and cost‑effective. Early pilot runs estimate a 40 % reduction in unit cost compared to high‑end cotton blends.
CELUSA is actively exploring commercial partnerships with manufacturing facilities in Australia and overseas. The company has already secured a trial partnership with a leading construction apparel supplier, integrating the new fabric into a prototype work‑uniform line scheduled for launch late next year.
Next Steps for Interested Stakeholders
Professionals seeking to upgrade their work wardrobe, marketers looking for green sponsorship opportunities, and research teams examining next‑generation textile technologies will find the developed platform an exciting opportunity. The technology is still pre‑production, but avenues for collaboration include:
- Participating in field‑trial programs to provide real‑world data.
- Co‑designing garment cuts that maximize the fabric’s cooling properties.
- Investing in joint venture agreements for large‑scale manufacturing.

Conclusion: A Cooler Future for Hot‑Climate Workforces
The Union of high‑tech and sustainable fashion heralds a new era where protection from thermal stress and environmental responsibility go hand in hand. CELUSA’s PLA/BNNS fabric demonstrates that advanced materials can deliver measurable temperature reductions and moisture control while remaining recyclable and affordable.
As global temperatures climb, innovations such as this present a pathway to safer, more comfortable working conditions without compromising ecological stewardship.
