Thermocore
A process specifically developed by Tecnifibre for the production of polyester monofilaments, with the aim of reducing their natural stiffness. The treatment involves a controlled sequence of heating and cooling phases throughout the stringing process, which allows the polyester's characteristics to be modulated, making it softer and more comfortable to use, while also helping to reduce the risk of fatigue and injury.
