HOW TO REMOVE STAINS
(These
notes integrate the
VIDEO)
 |
The Idrosmack equipment is
ideal for use in garment manufacturing and dry-cleaning plants. We invented
the “cold” (because it based on cold, compressed air) stain removal
system back in the 1960s. Our equipment is the result of almost 40 years of
improvements.
|
|
The cold spotting system is
based on the combined mechanical action exerted by compressed air at high
pressure (ideal pressure is between 8 and 10 bar) and a liquid (solvent or
water) flowing through a garment/cloth. This action dissolves the stain and
removes it through the tip of the spotting arm. This arm is always connected
to a vacuum unit: there are practically no fumes where the operator stands
and all is vented away. For best results vent the vacuum outlet outside the
building.
|
|
2 spotting spray guns are
provided: one for solvent/air and the other for water/air. A 3rd gun with
air only is provided for drying the garment.
|
|
Drying quickly after wetting
the garment avoids the creation of a ring.
|
|
The commonest type of stain is
caused by lubricating oil. Use the solvent gun and dry. It is normally a
very fast, quick and efficient procedure.
|
|
Should the stain not be
removed by the solvent, after drying the garment with the drying gun
provided, use the water gun on the stain.
|
|
Many non oily stains are
removed by water only. If the stain is only partially removed, wet the stain
again and apply some soap using the
soap sticks provided, (white for light
colour or delicate fabrics, green for the rest). Work up a lather on the
stain, rinse with the water gun and dry the garment.
|
|
After a while the operator is
able to recognize a stain and will take the appropriate steps from the
start, using the solvent or the water gun right off. |
|
Some specific, hard to remove stains, like ball point and rust need
specific
chemicals
(supplied in dispenser bottles): to move the stain apply
as little chemical as possible directly onto the stain from the bottle. Rub
the chemical into the stain as needed. Once the stain is moved, rinse with
the water or solvent guns (depending whether that chemical is water or
solvent based) and dry thoroughly.
|
|
By request, we can supply a
steam separator
and/or a steam generator (our model “VAPOR
1”, 5 liter
boiler capacity and can reach 4 bar of pressure) so as to be able to steam
spot as well as cold spot. When using steam, the operator should be familiar
with the problems associated with steam (colour loss, damage to fabric,
personal safety concerns, etc.). Try to wet the garment as little as
possible. The wetter, the more difficult and lengthy it is to dry the
garment.
|
|
Drawbacks of other systems
that we avoid with the cold spotting system:
|
-
electric gun: The system
tends to dilute the oily stain, rather than ‘blow’ it through the
cloth and to spread it over a much wider area, therefore with delicate
colours, it is difficult to avoid rings. It is easy to make a hole in the
garment and the consumption of solvent is high.
-
steam: as already mentioned,
it always presents a safety problem: it can cause damage to the fabric
and/or to the colour and is surely more expensive to use than cold water.
Also it will not normally remove oil. Last, but not least, it makes quite
a large wet spot on the garment making drying a lengthy task.
