For centuries, the art of textiles has been a labour of love—woven by skilled hands, guided by tradition, and passed down through generations. Gathered around looms, artisans interlaced not just yarn, but stories, culture, and craftsmanship into every fabric they created. While these traditions remain a cornerstone of the industry, the landscape has evolved dramatically, integrating advanced technologies without losing sight of its heritage. Today, the textile industry stands at a pivotal moment. As global demands shift, sustainability, efficiency, and technological innovation are no longer optional—they are imperative. While weaving and knitting endure as foundational techniques, the industry must embrace forward-thinking solutions to remain competitive and meet the challenges of a rapidly changing world. The future of textiles is being redefined, where tradition and innovation coexist to drive a new era of production and design. 

Leading this quiet revolution is Dr. Sonia Reynolds, Founder and CEO of Zephlinear Ltd. Her deep love for textiles and her strong curiosity led her to create FOYSE technology – a breakthrough that promises to redefine not just how fabrics are made, but how they serve our world.

Dr. Sonia Reynolds’s journey into textile innovation began well before the days of gleaming laboratories and the sound of clattering machinery. Her story is deeply rooted in her Jamaican heritage and the entrepreneurial spirit of her parents, who were part of the Windrush generation. “My parents were from Jamaica,” Dr. Reynolds recalls, “and they belonged to the Windrush generation. They ran a small textile manufacturing business in addition to their primary professions.” Her mother was a nurse by day, and her father was a bricklayer by night; together, they devoted their evenings to crafting knitted pullovers that her father sold to his colleagues on the building site.

These formative experiences gave young Sonia a profound understanding of textiles. She observed firsthand how fabric transcended mere utility, providing warmth, comfort, and a tangible expression of care. These early lessons—seeing fabric as more than just material—would profoundly influence her pioneering vision in the textile industry.

The Eureka Moment: An Observation that Changed Everything

“The idea for FOYSE,” Dr. Reynolds recalls, “came from an unexpected observation while working on a new design. When washing handcrafted wool panels, I noticed that cast-on and cast-off yarns naturally attached to the fabric without human intervention.”

This natural entanglement sparked a question in her mind: Could this spontaneous effect be harnessed and scaled to create a completely novel fabric structure?

Determined to find an answer, she began experimenting with alternative fabric structures. After much trial and error, her persistence paid off. Sonia developed FOYSE technology, which stands for Fiber On Yarn Surface Entanglement. This innovative process does away with traditional interlacing and interloping methods, opening the door to a fourth class of textile that was unlike anything the industry had seen before.

Academic Exploration: Learning from the Past, Innovating for the Future

As Dr. Sonia grew up, her childhood fascination with fabrics evolved into a dedicated academic pursuit. She immersed herself in textile design, mastering various disciplines, from traditional weaving, knitting, and nonwoven textiles to intricate embroidery and mixed media artistry. Her academic journey was intensely practical, filled with hands-on projects that encouraged experimentation with diverse materials and techniques.

Driven by her inquisitive mind, Dr. Sonia explored the potential of wool, wool-mixed, and hairy yarns for innovative textiles. A pivotal moment occurred when she came across an article discussing the challenges of embedding electronics into fabrics using conventional methods. This sparked her curiosity about alternative fabric structures, ultimately leading her to the work of Professor Tilak Dias, whose insights on interlacing and interlooping constraints inspired her deeper investigation. He later oversaw her PhD research into FOYSE technology, guiding her exploration into this groundbreaking innovation.

“My curiosity about new textile technologies,” Dr. Sonia explains, “led me to research alternative fabric structures, where I encountered the challenges of embedding electronics into textiles. This insight fueled my drive to further investigate FOYSE technology…”

Understanding FOYSE: Introducing a Fourth Class of Textile

FOYSE technology represents more than an incremental improvement; it is a paradigm shift, establishing a “4th class of textile” beyond the traditional trinity of woven, knitted, and felted fabrics. Unlike conventional methods, FOYSE creates fabric through a unique entanglement process.

To appreciate FOYSE’s innovation, it is essential to understand traditional textile manufacturing:

• Woven Fabrics: Two yarn ends are interlaced in a structured, grid-like pattern.
• Knitted Fabrics: A single yarn end is interlooped, forming flexible, interconnected loops.
• Felted Textiles: Loose fibers are bonded together through a matting process.

FOYSE diverges entirely from these methods making it a convergent innovation.  “FOYSE…entangles fibers onto the yarn surface,” Dr. Reynolds elaborates, “forming a unique noninterlaced fabric.”

This innovative method results in a seamless fabric where fibers on the yarn’s surface naturally intertwine. “The process,” Dr. Sonia notes, “is invisible to the naked eye, making it a completely unique fabric construction.”  The outcome is a fabric that retains the desired strength and durability of traditional textiles, yet offers a suite of enhanced characteristics, marking a profound advancement in textile engineering.

Zephlinear Ltd: Turning a Vision into Reality

Realizing the potential of her discovery, Sonia took a bold step and founded Zephlinear Ltd. A company whose purpose is to redefine textile manufacturing by introducing an entirely new way of creating fabrics—one that balances tradition, technology, and sustainability. Zephlinear is derived from “Zephyr,” meaning a soft breeze and also referring to delicate yarns and fabrics, and “Linear,” which relates to the structured flow of lines in art and design. Together, they embody lightness, fluidity, and precision, reflecting Zephlinear’s innovative approach to textile creation.

Her vision was to create textiles that were both technologically advanced and sustainable. The journey was challenging, as it required a completely new way of thinking about fabric production. However, her determination and belief in the power of FOYSE technology propelled her forward. Zephlinear Ltd became a platform for continuous innovation, blending modern science with the art of traditional textile manufacturing to create something truly extraordinary.
