Evolon® fabrics are produced using a unique textile manufacturing process invented by Freudenberg. Endless bi-component filaments are spun, uniformly laid on a belt, then simultaneously split into microfilaments and entangled using high pressure water jets to create the final fabric. No solvents or chemical binders are used in the process. Evolon® fabrics are suitable for an enormous range of applications, including but not limited to filters and face masks.
