Abstract
The area which is to be cleaned is intially subjected to a pulsating jet of a liquid which penetrates through the area and which liquid contains a cleaning agent. Thereafter the area is rinsed by a pulsating jet of water which also penetrates through the area. Accordingly, the dirt gets dissolved and a mechanical working of the respective area is achieved simultaneously with a rinsing away of the dirt. Immediately thereafter the now wet area is penetrated by a hot pressurized air jet such to achieve a driving away of the dampness and accordingly a complete drying. If necessary, above sequence is repeated. Due to the speedy drying a forming of rings at the cleaned area is prevented and it is immediately possible to see if a visually complete cleaning has been achieved.
Claims26
A method of removing stains from a soiled area of a planar textile article, comprising the steps of
- placing a soiled area of a planar textile article in a stretched condition over a water and air penetratable support;
- mechanically working said soiled area at least once by a jet consisting essentially of relatively highly pressurized liquid by directing said jet against said soiled area such as to cause said relatively highly pressurized essentially liquid jet to penetrate therethrough, whereby dirt which caused the staining is torn away from said stained area and is dragged along by said relatively highly pressurized essentially liquid jet;
- and
- immediately thereafter exposing said area to a jet consisting essentially of pressurized air such as to have the pressurized essentially air jet penetrate therethrough, whereby liquid is expelled and driven away from said area by the force of the pressurized essentially air jet and an immediate drying thereof is reached.
An apparatus for removing stains from a soiled area of a planar textile article, comprising
- a water and air penetratable support intended for supportingly receiving a soiled area of a textile article;
- a means for producing and discharging a jet consisting essentially of relatively highly pressurized hot water directed against the soiled area of such textile article stretched over said support whereby dirt which caused the staining is torn away from said stained area and is dragged along by said relatively highly pressurized essentially liquid jet;
- means for producing and discharging a jet consisting essentially of pressurized air directed against said area of such textile article placed onto said support whereby liquid is expelled and driven away from said area by the force of the pressurized essentially air jet and an immediate drying thereof is reached;
- and
- means for producing an induced draught operative to draw off at least the water which has been directed to said soiled area.
An apparatus for removing stains from a soiled area of a planar textile article, comprising
- a water and air penetratable support intended for supportingly receiving a soiled area of a textile article;
- at least one means for producing and discharging a jet consisting essentially of relatively highly pressurized liquid directed against the soiled area of the textile article stretched over said support whereby dirt which caused the staining is torn away from said area and is dragged along by said relatively highly pressurized essentially liquid jet;
- a means for producing and discharging a jet consisting essentially of pressurized air directed against said area of such textile article placed onto said support whereby liquid is expelled and driven away from said area by the force of the pressurized essentially air jet and an immediately drying thereof is reached.
