Circular Textile Technology: How a Circularised Fabric Is Created
The Problem with Traditional Textile Recycling: Why Fibres Degrade
For decades, the textile sector has experimented with recycling systems, yet most technologies still face the same structural limitation:
fibres are damaged during recovery.
Most of the technologies currently in use allow textile fibres to be reused only in supply chains different from the original one. This is because the mechanical or chemical processes used to separate and recover the fibres inevitably cause structural damage, resulting in their shortening and in the loss of their original properties.
The result is a recycled material of lower quality, often destined for less valuable uses or for applications completely different from the original textile product.
This approach, although technically a step forward towards sustainability, does not achieve a real circular economy, since it does not allow the material to be reintroduced into the same production cycle.
The Infibrity Patent: The Heart of Circular Textile Technology
The Key Is Stitch-Bond: A Reversible Bond
At the centre of Infibrity lies an innovative textile recycling technology, protected by a patented method titled:
“Method and processing apparatus for recycling a stitch-bonded nonwoven fabric and the corresponding recycled nonwoven fabric.”
The system is based on the structure of a stitch-bonded nonwoven fabric, where fibres are: laid in parallel, held together by a removable warp yarn.
This structure is essential.
The warp yarn can be removed without damaging the fibres, which can then be recovered at their original length, without mechanical deterioration.
Unlike conventional systems that shorten fibres and limit their reuse, this method enables textile circularity: fibres can be recovered, regenerated, and reintroduced into production with technical characteristics comparable to virgin material.
The patent was granted to Pratrivero, which has validated the effectiveness of the system through technical tests and real-world applications. This innovation represents a concrete step towards a sustainable and regenerative textile model.
The Fibre Recovery Process
Through a controlled combination of cutting or tearing, the stitch-bond fabric can be opened while preserving fibre integrity.
Technical tests have shown that, by processing the material with precise dimensions and parameters, an average fibre length comparable to that of the original raw material is obtained.
This is the foundation of the fibre recovery technology:
minimal damage, minimal waste, maximum preservation of material value.
Once the warp yarn and any finishes applied during the product’s life have been removed, the fibres can be reintegrated into the production cycle with properties similar to virgin fibres.
This system allows multiple regeneration cycles before any meaningful degradation appears — making the model genuinely circular and long-lasting.
The process unfolds in five key stages:
Product Design
Materials are selected and engineered to be compatible with the stitch-bond process and future fibre recovery.
No composite or non-separable components are used.
Stitch-Bond Fabric Production
The textile is manufactured using the patented method, creating a structure that guarantees durability and recoverability.
Use Phase
The product enters the market and performs according to its intended technical specifications.
End-of-Life Take-Back
At the end of its usable life, the product is collected and prepared for the recovery phase.
Fibre Transformation and Regeneration
Fibres are recovered at their original length, free from finishes, and reintroduced as high-quality raw material for new production cycles.
Lo Schema di Circolarizzazione: 5 Fasi per un Ciclo Reale
Infibrity technology has been developed to guarantee a truly circular cycle, which extends from the initial design of the product through to the recovery and reuse of the fibres, while maintaining a high quality level.
This approach does not close the loop once — it allows the loop to be closed multiple times, enhancing the value of each fibre and reducing environmental impact. Circularity becomes a measurable, repeatable, and scalable reality only when design, production, and recycling operate coherently.
