Abstract

Water soluble detergents and enzymes are used for mechanically cleaning textiles or crockery. According to the invention, enzymes with a catalytic effect on typical stains are added to the washing or cleaning process, only for as long as their catalytic effect is desired. This avoids superfluous removal of the enzymes that have been used in a washing or cleaning process.

Claims

1. A method for mechanically cleaning textiles or solid objects such as crockery using water-soluble detergents and/or cleaning agents and enzymes, characterised in that catalytically-acting enzymes (E) are added to the washing or cleaning process to remove typical stains, but only for as long (t₁) as their catalytic effect is desired.

2. Enzymatic detergents and/or cleaning agents for use in a method according to claim 1, characterised in that the enzymes (7) are macroscopically encapsulated by means of a polymer membrane which is permeable to the washing liquid, but insoluble in water.

3. The detergent and/or cleaning agent according to claim 2 characterised in that the capsules (12) consists of several hollow bodies linked to one another.

4. The detergent and/or cleaning agent according to claim 3 characterised in that the hollow bodies are linked to form cartridges and/or bars and/or tubular bodies.

5. The detergent and/or cleaning agent according to one of claims 2 to 4 characterised in that the capsules (12) or the linked hollow bodies for cleaning textiles or solid objects (e.g. crockery) are stationarily but replaceably arranged at a location (6) in a machine which is accessible to the washing or cleaning liquid.

6. The detergent and/or cleaning agent according to claim 5 characterised in that the location (6) is protected by a filter (13, 14) against insoluble impurities in the washing or cleaning liquid.

7. The detergent and/or cleaning agent according to one of claims 2 to 6 characterised in that the capsules (12) or hollow bodies are filled with various enzymes (7) suited to various types of stains.

8. The detergent and/or cleaning agent according to claim 7 characterised in that a specific enzyme is provided for each type of stain occurring in mechanically applied washing or cleaning processes.
