Process for machine washing of soiled articles using a water-insoluble cation-exchange polymer |
摘要 |
The machine washing of solid material (e.g. dishes and clothes) in hard water areas is enhanced when the washing solution has a dissolved content of a sequestering agent for calcium ions and is contacted with an insoluble cation exchange resin in particulate state, the washing solution being passed through a filter containing the resin during the course of the washing operation. The filter is maintained separate and spaced from the washing area. The cation exchange resin may be contained in a filter of the whirlpool type, so that the particles are maintained in aqueous suspension without coming into contact with the materials being washed, or it may be contained as a unitary porous lining of a filter.
