Mechanical recycling starts with shredding or grinding the polyester materials to smaller bits called flakes which are then remelted and re-extruded into fibers, yarns or even pellets. This form of recycling is quite energy efficient and its popularity has risen. However, the fiber quality deteriorates when this process is reused multiple times.

An example of advanced recycling processes is JUVITY, which through polyesther’s chemical recycling, separates it into core monomers such as dimethyl terephthalate (DMT) or terephthalic acid (TPA). After these monomers go through purification, they are re-polymerized into polyester of the same quality as virgin materials. Although this approached is multifaceted and resource intensive, it guarantees the optimal durability, appearance and performance of the recycled polyester.

How Does Recycling Affect the Quality of Polyester Yarn?

The process of Recycling Polyester Yarn involves changing used materials into new fibers while meeting a certain quality standard. The mechanical processing done “in Mechanical Recycling” can lead to some loss in elasticity and strength. This means that when compared to virgin polyester there is some tensile strength and elasticity. More advanced techniques, such as glycolysis, methanolysis, or enzymatic hydrolysis, can restore the polymer chain structure by removing some non-desired materials. These advanced techniques have shown to enhance the molecular structure of polyester thus restoring its full polymer properties. Research proves that chemically recycled polyester works perfectly in terms of durability, resilience, and dye retention. In addition, recycling energy spent is far less than the energy spent producing virgin materials.
