Method and apparatus for making on-line stabilized absorbent materials

   
   

A method for forming a stabilized airlaid layer (86) can include an airforming of a substantially unbonded fibrous layer (66) which includes absorbent fibers and binder-fibers. The fibrous layer (66) is exposed to high-frequency electromagnetic energy during a distinctively short activation period to activate the binder-fibers to provide the stabilized, airlaid layer (86). In a particular aspect the activation period can be not more than about 3 sec.

Un método para formar una capa estabilizada del airlaid (86) puede incluir airforming de a unbonded substancialmente la capa fibrosa (66) que incluye fibras y carpeta-fibras absorbentes. La capa fibrosa (66) se expone a la energía electromágnetica de alta frecuencia durante un período distintivo corto de la activación para activar las carpeta-fibras para proporcionar haber estabilizado, capa del airlaid (86). En un aspecto particular el período de la activación puede ser no más que cerca de 3 sec.
