  • Patent number: 4806410
    Abstract: Processes for the production of antistatic or static dissipative papers. The papers produced may be expeditiously used in dunnage converter machines operable to produce an antistatic (static dissipative) resilient pad-like cushioning dunnage product, for packaging and the like. In one of the processes, liquid antistatic material is applied to a still wet porous paper web produced on a Fourdrinier-type paper making machine, and in predetermined amount for impregnation therein, prior to the completion of the drying of the paper. In another process, a web of dry paper is impregnated with liquid antistatic material, and then the treated web is dried.
