Patent DE-19720355-A1 (DE)
Inventor: BERGHAUS OTMAR
IPC: A47L25/08
Filed: 1997-05-15
Abstract: A process and device are disclosed for removing stains from textile goods. When stains are locally removed from textile goods (10) circlings are often formed by part of the cleaning liquid, because the humidity spreads into the textile good (10). Moreover, the cost of devices for removing stains is considerable, as they use several powerful pumps. In order to avoid these disadvantages, cleaning liquid is sucked into the textile good (10) and sucked again out of the textile good (10) by a negative pressure generated by a pump (40). The liquid is sucked through the textile good and the formation of circlings is avoided at a low cost thanks to the suction effect.
