ABSTRACT:
Conductive meltblown fabrics are disclosed which have improved strength and hand over conventional conductive meltblown fabrics. Also disclosed is a process for spraying a solution containing a conductive agent into a molten stream of meltblown fibers before they are deposited onto a forming wire. By applying the solution onto the fibers before they are deposited onto the forming wire, the heat of the molten stream vaporizes the solvent carrying the conductive agent and thereby eliminates the need to subsequently dry the formed material. By eliminating the drying step, degradation of the strength and hardening of the hand of the material normally resulting from the wetting and drying of meltblown fabrics are avoided. There is also disclosed a conductive SMS laminate having a conductive meltblown layer sandwiched between two untreated and nonconductive spunbond layers.
