Laundry Theory - Fisher & Paykel AquaSmart WL26CW1 Product Information

Removing soil from clothes relies on three forms of energy in
varying degrees:
1. Mechanical Energy provided by the washing machine or hand
2. Chemical Energy provided by the detergent
3. Thermal Energy in the form of hot water
The contribution of these three factors will determine the
wash performance of any machine
Achieving acceptable wash performance is not just about getting the clothes clean. All three of
the factors described above can potentially cause damage to clothing if they are not applied
with due care.
Too much mechanical action causes excessive rubbing (abrasion) of the clothes that can cause
cottons to 'pill' or woollen's to 'felt'.
dye/colour run, and wrinkling. Harsh detergents can cause irreparable fibre damage, weakening
the fabric and making it more susceptible to rips and tears.
Achieving acceptable wash performance is about getting the right balance between soil removal
and any negative 'side-effects'. The contribution of the three factors to the cleaning process
depends on the method of washing. For example, if clothes are washed on rocks by a river, the
contribution of mechanical action is enormous compared to the other two factors.
comparison, if clothes are washed in a front-loading washer the mechanical action is decreased,
but the thermal and chemical energy is increased. In a traditional top-loading washing machine,
thermal energy typically plays a slightly less important role and the mechanical energy slightly
more.
The wash action of AquaSmart™ is somewhere in between that of a traditional top loader and a
front loader. The low wash volumes mean that detergent is more highly concentrated, meaning
increased chemical energy is imparted on the load. Mechanical action is still important, however
the wash action is different to a traditional top loader. The clothes gently roll over each other,
rather than being pushed by an agitator.
