ABSTRACT:
A process is disclosed for bonding blends of cellulosic fluff pulp and fusible synthetic pulp or fiber having a melting point less than 250.degree. C., by high-speed dielectric heating. The process works in the absence of any dielectric sensitizing material, but requires the resulting blend have a density between 0.005 and 0.50 g/cc so that the blend can be bonded in less than 15 seconds. The process is useful for producing disposable baby diapers, adult incontinence products and feminine pads.
