3. COMMERCIAL LAUNDRIES
These are also known as off site laundry or
contracted laundries.
These cater to hotel on a contract basis.
Usually the soiled linen are laundered & delivered
back to the hotel within 24-48 hours.

4. ON-PREMISES LAUNDARIES (OPL)
These are also known as on-site laundry or in-
house laundry.
It is the hotel’s own laundry situated on its
premises.
It may be run by the management or managed on
a contract.
Services are faster (maximum of 8 hours), hence
the stocks are reduced.
There is better control, better supervisor, and
hence a long life for linen.

10. 1.PRE-WASHING
1. The soiled linen are collected from all the
departments of the Hotel like F&B, Kitchen,
Banquets, etc.
2. The soiled linen are then transported to the laundry
in two ways, first is, the soiled linen are put in the
trolley and are then taken to the laundry via
elevators and the second way is that the soiled linen
are dumped into the linen chute which is directly
connected to the laundry.
3. The soiled linen are then sorted on three basis i.e.
by the type of fabric, color of the fabric, and degree
of soiling.
4. After sorting the soiled linen, the linen are weighed
according to the washing machine capacity and are
10 Dr Chef Sunil Kumar
11. 2.WASHING
The washing depends on 4 things which varies as
per the fabric:-
Fabric temperature Water level Time
Less soiled Low Less less
More soiled high more More
11 Dr Chef Sunil Kumar
12. This is done by using hot and cold water,
which are usually recovered 7 recycled
from earlier steps during the last rinse in
order to save water.
3.RINSING
12 Dr Chef Sunil Kumar
13. Hydro means water & extraction to
remove. Extraction removes at least 80%
of the water from the linen used in the
rinsing process. It also reduces the drying
time.

17. In this process, the washing machine
automatically sucks the high level of water in
which the soiled linen are added at medium
temperature to reduce the soil load for the
upcoming suds flushes.
FLUSH
17 Dr Chef Sunil Kumar
18. In this stage, the high alkaline product is
added, which may be followed by additional
flushes. The break cycle is usually carried
out at a medium temperature and low water
level.
BREAK
18 Dr Chef Sunil Kumar
19. This is the actual wash cycle in which acid
part of the hoppers is sucked by the
machine. It takes place in hot water at low
water level.
SUDS
19 Dr Chef Sunil Kumar
20. This rinse cycle removes soils and alkaline to
help the bleach work more effectively later. In
this process 50-60% water is removed from
the linen.
INTERMEDIATE-RINSE
20 Dr Chef Sunil Kumar
21. In this stage, the washing machine sucks the
bleach automatically from the hoppers in the
hot water at a low water level. Bleach kills
bacteria, whitens fabrics and removes stains.
BLEACH
21 Dr Chef Sunil Kumar
22. The washing machine sucks the high level of
water and remove detergent and soils from
the linen.
RINSE
22 Dr Chef Sunil Kumar
23. This high speed spin removes left over detergent
and soil from the linen, usually after the first rinse
step. It removes 70% of water from the linen. The
washing machine spins at 200 RPM.
INTERMEDIATE-EXTRACT
23 Dr Chef Sunil Kumar
24. Softener and sours are added to condition
fabric. This cycle is run at a medium
temperature and at low water level. Starches
are added to stiffen cotton fabrics. Sizing
may also replace the sour/softener step.
SOFTENER/SIZING
24 Dr Chef Sunil Kumar
25. A high speed spin removes most of the
moisture from the linen. The length of the
spin depends on the fabric type, extractor
capacity, and extractor spend. Around 95%
of water is removed in this stage.

28. DRY CLEANING
This is the cleaning of fabrics in substantially non-
aqueous liquid medium.
Dry cleaning removes oils as well as many water soluble
& some insoluble materials with the help of detergents &
various other agents.
It is done by using dry powder, liquid such as petrol,
benzene, & so on.
Unlike laundry, dry cleaning does not cause swelling of
the fibers, & so does not lead to shrinkage , wrinkle, &
bleeding of color of the fabric and thus it is a safe method
for cleaning delicate textiles.
It was earlier known as ‘French Cleaning’ or ‘Chemical
Cleaning’.
28 Dr Chef Sunil Kumar
29. ADVANTAGES OF DRY
CLEANING
Dry cleaning cleans clothes for which laundering is
not suitable.
It causes no shrinkage to the fabric.
It does not flatten the pile of fabrics such as velvet.
Finishes such as moireing are retained even after
dry-cleaning.
Colors do not bleed on dry-cleaning.
Stains are more readily removed by dry-cleaning.
29 Dr Chef Sunil Kumar
30. DISADVANTAGES OF DRY-
CLEANING
Dry-cleaning is expensive as compare to the
laundering.
Many dry-cleaning solvents are harmful to health if
inhaled for long duration.
After cleaning with solvents, a certain unpleasant
smell tends to be retained by the articles.

31 Dr Chef Sunil Kumar
32. When soiled linen garments are delivered for dry-
cleaning, they are first sent to the marking areas.
Here, a piece of white fabric with a number or some
other code stamped on it with indelible marking ink
is securely attached to the garments. Every article is
marked individually to facilitate identification.
MARKING
32 Dr Chef Sunil Kumar
33. The garments then pass on to the sorting
areas.it is done on the basis of soil
level,colour and in this case the
fabric/cloth pouches are checked for the
valuables of the guests.
SORTING
33 Dr Chef Sunil Kumar
34. Absorbents are applied to remove grease
spots from all kind of materials like french
chalk,bran or flour etc/
APPLICATION OF ABSORBENTS
34 Dr Chef Sunil Kumar
35. Heavily soiled areas of the garments are
treated with solvents. Volatile dry solvents
such as amyl acetate to remove oil-borne
stains, while non-volatile solvents are used on
paint and varnish stains.
PRE-SPOTTING
35 Dr Chef Sunil Kumar
36. A load of approximately 45kg is
transferred to the dry-cleaning cylinder.
Very delicate cloths are placed in a net
bags first. An appropriate solvent is
circulated through the clothes.
CLEANING
36 Dr Chef Sunil Kumar
37. Excess solvent is removed from the
garments by centrafugal action in a
revolving perforated cylinder contained in
a tumbler.
EXTRACTION
37 Dr Chef Sunil Kumar
38. After extraction, the garments are dried in
a dryer that has a perforated drum
enclosed in a tumbler.The temperature for
the same should not exceed 70 degree as
otherwise it may catch fire.
DRYING
38 Dr Chef Sunil Kumar
39. Solvents are expensive and therefore
filtered out, distilled, and reused, they are
not allowed to evaporate after use. But
used in recycled manner
FILTERING & DISTILLATION
OF THE SOLVENT
39 Dr Chef Sunil Kumar
40. Dried garments are inspected to check
that they are perfectly clean. If necessary,
they are spot-cleaned a second time.
INSPECTION
40 Dr Chef Sunil Kumar
41. In this process, the garments are restored
as nearly as possible to its original size,
shape, feel, and appearance.
FINISHING
41 Dr Chef Sunil Kumar
42. Buttons and buckles that had been removed
are stitched back on. Finally the garments are
packed in a paper or suspended from clothes
hangers covered with polythene bags. They
are now ready for delivery
PACKING

45. A stain is a spot or localized discolouration
left on fabric by reaction of a foreign
substance or absorption or adsorption of
any unwanted colour,liquid etc
STAIN
45 Dr Chef Sunil Kumar
46. Stain removal or spot cleaning is a skill that
demands special attraction, special techniques, and
long experience.
