Abstract

Filter elements are made by forming a band of continuous filaments, applying to the band a bonding agent in the form of a fusible powder, condensing the band into a cylindrical shape and subjecting the formed cylindrical elements to heat in order to fuse the bonding agent. The band may be a tow of crimped continuous-filament cellulose acetate. Filaments of regenerated cellulose, polyesters, polyamides, polyolefines, acrylonitrile polymers, or regenerated proteins may also be used. The powdered bonding agent may be applied by spraying, by gravity feeding or by passing the web through a fluidized bed of the powdered material. The bonding agent may be a polyethylene glycol, a polyvinyl butyral, cellulose acetate, polyethylene, nylon or a copolymer of acrylonitrile and styrene. Powdered charcoal or other filter aid may be incorporated with the bonding agent.ALSO:Filter elements are made by forming a band of continuous filaments, applying to the band a bonding agent in the form of a fusible powder, condensing the band into a cylindrical shape and subjecting the formed cylindrical elements to heat in order to fuse the bonding agent.
