3.3 Classification of soiling
The dirt in the fabrics consists essentially of:
PROTEICN-BASED
substances
OXIDABLE
substances
GREASE
VARIOUS
substances
CHEMICAL
substances
Protein soiling (enzymatic) - sensitive to ENZYMES
Blood, Eggs, Chocolate, Grass etc.
Oxidable substances - sensitive to BLEACH
Wine, Tea, Coffee, Fruit etc.
Greasy soiling - sensitive to SURFACE-ACTIVE AGENTS
Oil, Butter, Salt etc.
Various types of soiling - sensitive to specific products
Rust, Chewing-gum, Mildew
Chemical soiling - sensitive to specific products
Ink, Mercury-Chrome, Deodorants, Paints
3.4 Mechanical
action
The mechanical action of the appliance is produced by the combination of clockwise/anti-clockwise rotation
of the drum, which agitates the wash load in the washing solution. This action tends to transfer the dirt from
the fabrics to the washing solution (water + chemical products).
The mechanical action may be VIGOROUS or DELICATE:
Vigorous drum movement in alternating directions (clockwise and anti-clockwise) is suitable for cotton
and polyester fabrics.
Delicate drum movement in alternating directions (clockwise and anti-clockwise) is suitable for wool and
delicate fibres.
3.5 Duration of the washing cycle
Each washing cycle requires a minimum duration in order to guarantee satisfactory results. The duration of
the cycle depends on the type of fabric, the type of soiling and the quantity of washing in the drum.
