Process for bonding blends of cellulosic pulp and fusible polyolefin or polyester pulp by high-speed dielectric heating and products produced thereby.

摘要

A process is disclosed for bonding blends of cellulosic fluff pulp and fusible polyolefin or polyester pulp or fiber having a melting point less than 150 DEG 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 0.02 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. <IMAGE>
