3.3 Classification of soiling The dirt in the fabrics consists essentially of: ѓ PROTEICN-BASED substances ѓ OXIDABLE substances ѓ GREASE ѓ VARIOUS substances ѓ 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: ѓ Vigorous drum movement in alternating directions (clockwise and anti-clockwise) is suitable for cotton and polyester fabrics.
ѓ 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. SOI/DT 2006-03 dmm 10/70 599 37 67-82
