What is Econyl®?

Econyl® is a regenerated nylon fabric made entirely from recycled waste materials. Launched in 2011 by Italian company Aquafil, Econyl® represents a significant step forward in sustainable textile production.

At its core, Econyl® is a type of nylon. But unlike conventional nylon, which relies on virgin materials and fossil fuels, Econyl® gives new life to existing nylon waste. This approach reduces reliance on non-renewable resources and helps clean up environmental pollution.

The Econyl ® Production Process

The journey from waste to wearable fabric involves several key steps:

Collection: The process starts by gathering nylon waste from various sources. This includes discarded fishing nets, old carpets, and industrial plastic scraps.
Sorting and Cleaning: The collected materials undergo thorough sorting and cleaning to remove contaminants and prepare them for processing.
Depolymerization: This crucial step breaks down the nylon polymers into their original building blocks, called monomers.
Purification: The monomers are purified to ensure a high-quality end product.
Repolymerization: The purified monomers are then reformed into new nylon polymers.
Processing: Finally, the regenerated nylon is processed into yarn and fabric, ready for use in various products.

This closed-loop system allows Econyl to be recycled repeatedly without losing quality. It's a practical example of circular economy principles in action.

Econyl fits into this broader context by offering a more sustainable alternative to a widely used synthetic fabric. Its success could pave the way for similar innovations in other areas of textile production.

The Science Behind Econyl

Understanding the science behind Econyl helps appreciate its innovative nature:

Polymer Chemistry: Nylon is a synthetic polymer, meaning it's made up of long chains of repeating molecular units. The Econyl process involves breaking these chains back down into their component parts and then rebuilding them.
Depolymerization: This is the key step that sets Econyl apart. Using heat and pressure, the nylon waste is broken down into its original monomer, caprolactam. This process effectively "unzips" the nylon polymer.
Purification: The recovered caprolactam is then purified to remove any contaminants or non-nylon materials that may have been present in the waste.
Repolymerization: The purified caprolactam is then polymerized again, reforming the long chains that give nylon its characteristic properties.

This chemical recycling process is more complex than mechanical recycling (which simply melts and reshapes plastics) but results in a higher-quality end product that's indistinguishable from virgin nylon.
