Binder fiber for recyclable, self-reinforcing nonwovens
The preferred choice for a functional and strong network is regular polyester fiber. A broad range of nonwovens with engineered properties can be created, including thermo-formable composites consisting of a single polymer. The processed combination of crystalline and amorphous fiber results in self-reinforcing structures which is triggered by thermal treatment: the end product can be molded into any shape to fit the technical needs. The technology can replace for example injection molding. It can also be used for applications such as fine-pored filters.
