Title: Removal of chewing gum contamination from carpets and fabrics
Inventor: KENT DONALD ARTHUR
IPC: B08B7/04
Filed: 1983-06-02
Abstract: An apparatus to facilitate the effective use of liquid surfactants in a specific cleansing operation which is the removal of contaminating chewing-gum wads adhering to carpet- or fabric fibres, where access to the site of contamination is possible from one side only of the carpet or fabric, that side being the side carrying the contaminant. The method of contaminant removal which is provided is in contrast to methods employing solvents or freezing agents in that the bulk-structure of the contaminant gum is not changed, permitting gum-wads to be removed in one piece without proliferation. The apparatus embodies a hollow needle as means to deposit surfactant liquid at or close to the gum/carpet or gum/fabric interface. With subsequent conduction of surfactants along carpet- or fabric fibres, wetting of the entire bond-interface is effected leading to bond-strength reduction such that the contaminant may be removed without residue.
