5. LAUNDRY
Laundry washing looks very simple, if one looks in details it is a complex process.
If the washing is to be done well, a thorough understanding of the washing process is
Necessity.
Objectives:
The objective of laundry is to return soiled textiles to a clean, hygienic and ready for
Use state without undue damage.
Laundry washing:
• The cleaning of textile using water and chemicals. In this Case water is using as
Solvent & having the power of dissolving other substances.
The water as a solvent ( the natural & synthetic fiber have an ability to shrink
and bleed).
Dry Cleaning:
• The cleaning of textiles using organic solvents. In this Case Organic solvents
Like Perchlorethylene & Fluorocarbon is using as Solvent & having the power
Of dissolving other substances instead of water.

6. Detergent
• It is cleaning agent containing surface active agent.
• It clean & remove all types of soil at low to high temperature.
• It should have the capability to remove and dissolve fats and beverage stains.
• It should be easily soluble in water
• It can works actively on all types of fibers without reducing the fabric
Strength.
• Surface active agent called surfactant ( a substance introduced into a liquid in
Order to affect usually to increase its spreading, wetting, & similar properties
i.e., properties which depends upon its surface tension).
• It may contain ENZYMES.
• It may contain ACTIVE BLEACHING AGENT. It can restore the white color.
• It may contain WETTING & DISPERSING AGENT.
• It may contain SOFTENING AGENT. It can act both in hard and soft water.
• It may contain DEFOAMER
• It may contain ANTI-STATIC AGENT.
• It may contain PERFUMED.
• They are distinct from soap because
1- They are alkyl arene sulphonates, sulphated aliphatic alcohols etc.
2- They are effective in hard water & soft water & do not forms a scum like soap.

7. Soap:
• It is a mixture of sodium or potassium salts of Stearic acid C17H35COOH,
Palmitic Acid C15H31COOH & Oleic Acid C17H33COOH.
• Soaps are made by the action of sodium or potassium hydroxide on fats , this
Action is called hydrolysis or saponification which gives soap and glycerol as a
By product.
Textiles should be washed depends on the following characteristics
• Types of textile fiber
• Structure and character of the textile material ( Type of Weave )
• Color fastness
• Wash durability of textile
• Type and quality of garment ( Stitching & style )
In the past, fabric were only made from natural fibers such as cotton, linen, wool,
and silk. Today we use a range of different man made fibers and mixture of natural &
Artificial fibers.
Fibers:
Textile fiber is defined as a unit of matter characterized by
• Flexibility
• Fineness
• High ratio of length to breadth minimum is 100.
Fibers are the raw material for manufacturing yarn and yarn can be converted into
Fabric by weaving or knitting.

8. Fabric:
Fabric should have the following properties like
• Comfort
• Warmth
• Durable
• Easy of wash
• Crease recovery
• Cost
Classification of Fibers:
It can be classified into two groups
1- Natural fibers ( it is obtained from natural sources like plants e.g. cotton flax
& jutes from animals e.g. wool & silk)
2- Man made fibers ( It is further classified into two groups )
a- Synthetic fiber ( It is made by man by the process of polymerization of
Specific chemicals e.g., Polyester, Nylon, Acrylic. )
b- Regenerated fiber ( It is made by man by using of naturally occurring
Polymer e.g., Viscose

9. Identification of fiber:
We can identify the fiber by burning test method.

11. Water:
Natural water contains dissolved salts in different quantities like calcium and
Magnesium salts of sulphates, carbonates & chlorides. These salts make the water
Harden & affect the washing process.
Water hardness is measured as follows:
1 gram CaO in 100 liter water equals 1 dH (German hardness)
Which is equivalent to 1.25 eH (English hardness)
Or 1.79 fH (French hardness)
Incrustation:
The salts in hard water react with certain substances present in the unsuitable washing
Powders, residues in the form of incrustations will be deposited on the washing and
In the machines. Incrustation cause washing to look grey and unsightly and damage
The fabric & it is not good for the machines.
Therefore laundries will Endeavour to use soft water. In the past you would find
Laundries near rivers as the soft water from rivers were suitable for washing. Currently
Water softening plant are used & it is more difficult to obtain water of good quality
And the cost for softening is increasing. This necessitates the use of water saving
Procedures in the laundry.

12. Laundry water should be:
• Soft
• Free of iron ( max 0.1 mg / lit )
• Free of manganese ( max 0.05 mg / lit )
• Clean & odor free
• pH about 7
What is dirt?
Dirt is any undesirable foreign matter on textiles
It consists of many different components. Specific dirt component are found on
Fabrics depending on type and use of textile material. Dirt found on underwear and
Bed linen is usually sweat, skin fat, protein and urine, laundry will also have blood
And some skin ointments. One will find specific types of soiling in linen from
Workshops, F&B & Health club etc.

13. We can categorize dirt as follows:
1- washable dirt
Any type of dirt which can be rinsed from the textile material with water
Alone or together with washing powder is called washable dirt e.g. protein,
Pigments, blood, urine, carbohydrates & fats.
2- Dirt which can be dissolved in organic solvent
Dirt consist of difficult stains such as fats and oils, paints and varnishes and
Dyes. These stains are sometime difficult to remove completely.
3- Bleachable dirt
Dirt consist of dyes which are not washed out by means of laundering or dry-
Cleaning. A special bleaching during the washing cycle can be performed.
Bleaching is an oxidizing process which destroys the pigment dye.
Composition of dirt & its affinity towards textiles.
Quantity in % Kind of soiling Method of washing
15-20 Salt Water soluble
5-7 Urea Clean with water
20-25 Protein Water insoluble
Approx.20 Carbohydrates Water insoluble
5-10 Fats Water insoluble
25-30 pigment Bleachable in water

14. Detergents for industrial laundering
Detergents for industrial laundering must meet the following criteria:
• They must have good washing efficiency.
• The textile material must not be damaged.
• The detergent should be easy to use.
• They should be suitable in any type of machinery & system.
• Low foams must be guaranteed.
• Incrustation on textiles and machines must be avoided.
• The composition of the washing powder must be adjusted to the prevailing water hardness.
• Soil releasing power and dirt suspension should be the criteria for detergent.
Detergents are complex mixture of various chemicals. Each component of this
Mixture has its own task to fulfill in conjunction with other chemicals. Only a
Combination of all those ingredients in the correct proportions can fulfill the
Requirements as mentioned above.
Surfactant (wetting agents) is water soluble and reduces the surface tension of water
Salts such as polyphosphates
Alkalis such as soda ash, orthophosphates etc.

15. Additives such as CMC, magnesium silicate (dirt dispenser)
They will ensure that the soil is removed without unnecessary damaged to the fabric,
& no undesired incrustations on the fabric.
In past when soap was used together with alkalis such as caustic soda or soda ash, the
Combination of soap and hard water salts caused problem by graying the washing and
Diminishing the moisture absorbing capacity of the garments.
Detergents rinse out very well and quickly even in cold water, the soap used in past
Hard to rinsed out even in hot water, which is both time consuming, energy and
Water.
In the days when washing powder consisted mainly of soap and soda for the laundry
Expert lather was a sure sign of strength in the washing solution. As long as solution
Gave foam, the laundry man knew that the solution contained sufficient active soap
For washing and was not bound to the calcium in the water. The foam level indicated
The presence of the wash active substances.

16. Today situation is different instead of soap we are using synthetic anionic and non
Ionic surfactant, the great advantage of synthetic surfactant over soap is that they are
Usually not easily affected by hard water.
Important characteristics of wash active substances in combination with alkalis,
Phosphates, dirt suspenders, bleaches and optical brighteners.
• Wetting of the fiber by reducing the surface tension of water.
• Dispersing solid dirt and lifting out dirt from the textile material.
• Emulsifying fatty, oily substances and lifting those from the textile fabric.
• Keeping dirt in suspension in the washing solution and avoiding redeposit.
• Bleaching of stains.
• Giving the high degree of whiteness to the white fabric.
Washing Machines
The first line shows the manual work and labor intensive washing in the laundry. It consist of
Sorting of laundry
Loading
Extracting by centrifuging
Drying
Ironing, pressing & calendaring
Folding
Second line shows how all these different operations can be simplified by making use of new
development in machinery and more efficient washing through the use of more automated &
mechanized machine. Continuous washing machines are used in large laundries, where with a
minimum of labor and personnel, the washing is handled on an assembly line basis.

17. Third line shows the visualized machine where the dirty washing enters on one side and comes out on
the other side, washed, bleached, pressed, folded & packed. Development work is being conducted in
this direction.
Principally we are using double drum washer for washing. There are two drums
Outer drum It has lockable doors
I loads the washing and dose the water & chemicals.
It holds the drain line.
It holds the inner drum shaft.
Inner drum It can rotate in both directions
There are ribs present inside the inner drum
These ribs pull up the laundry and let it falls & this gives the
Mechanical action to the washing process.
The inner drum is perforated, the laundry comes into contact
With the chemicals and water through these perforations.
Mechanism of washing machines
The detergent solution in the outer drum is filled up to a certain level , when rotating the ribs of inner
drum lift the wash out of the float and, by further rotation, the washing falls back into the liquor
again. This principle of moving the wash helps enormously in the cleaning action.
To avoid washing getting tangled, the machine is programmed to run a certain numbers of times in
one direction and then the same # of revolution in other direction called RPM.
Washing machines are mostly consisting of stainless steel due to corrosion reason.
New and latest double drum machines mostly have the following
Power supply, heating system, loading, draining, closures, and thermometers, different type of
gauges, inspection windows, different program or individual process information can be stored by
program card, centrifuging within the same machines, etc.
There is important to know the exact loading capacity of the machines, incorrect loading can lead to
problems in the washing process, the loading capacity is expressed in kg of dry laundry.
Liquor ratio is also important to know the relation between kg of laundry and water. Only with the
correct ratio will the laundry have sufficient space to ensure good washing result. It is defined as 1 kg
of dry washing in relation to the drum volume in 1 liter. In practice 1 : 8 to 1 : 12 is reasonable.

18. Lightly soiled washing requires less volume than heavily soiled textiles. The loading capacity is
calculated by dividing the total volume of the drum by the required volume per kg dry wash (fill ratio)
e.g.
Volume of the drum 226 lit
Soiling of washing light
Fill ratio 1 : 8
Loading capacity is 226 : 8 =28.25 kg of dry wash
If the volume of the drum is not known then we use the following equation
Interesting facts about washing process
The following factors are important:
• Type, weave & dye of textile material.
• Kind & degree of soiling.
• Type of washing machines.
• Quality of water.
• Available detergents and bleaches.
• Quality requirement in regard to cleanliness, stain removal, hygiene, wear etc.
• Desired garment finish as well as washing habits.
Rules for sorting:
• White washing is first separated from colored material.
• White washing is sorted according to the degree of soiling i.e. light, normal, & very dirty soiled.
• The colored washing is separated into light, medium & dark colored garments.
• Woolen is sort out separately as these should not be washed with white or colored washing.
• The following always wash separately

19. Mechanics overalls
Mixed overalls
Kitchen washing
Blood stained
By following the rules of sorting we can make it possible to give each laundry type its own process,
thereby avoiding damages & problems.
Factors influence on washing process:
We always need these four factors to achieve good results. The four factors may vary in relation to
each other, but it is not possible to leave one factor out when designing a good washing process.
Important terms used in washing:
• Mechanical Action: Type of washing machines, the drop of height, Float ratio, Loading Ratio,
RPM of the Machines etc.
• Chemicals: Concentration of chemicals and Bleaches.
• Temperatures: Cold, Warm & Hot Water.

20. • Time: Duration of total process.
• Liquor: This is the liquid in the washing machines called float & it can be sub divided into the
float bound by the fabrics and the float which is not absorbed or free float. This sub division is
important as an exchange of the float will replace the free float. The bound float together with
any chemicals will be transferred to the next washing cycle. The bound float constitute 2-3
times the weight of the dry washing i.e. 2-3 liter / kg.
• Liquor Ratio: The ratio between dry weights of the load and the water e.g. 1: 5 means that I kg
of dry fabric load requires 5 liter of water.
• Soaking: The washing is submerged in a solution in large containers or in washing machines.
This was often done in past.
• Pre-rinse: Pre-rinsing of textiles in cold water without chemicals to rinse off large dirt particles
or to increase the wetting of load.
• Pre-wash: The first cycle of any process to remove a major portion of the soil.
• Main wash: The major washing to remove all remaining soil.
• Bleaching: This is done in a separate cycle to remove bleachable stain.
The Process of BLEACHING
There are different kind of soiling are present on textiles, among others we have a range of different
soiling consisting of dyes from fruits, vegetables, coffee, tea & wine which are not removed by
detergent alone. These stains must be removed by a washing powder containing bleaching agent
called (Per borate) or by chlorine bleach in a separate cycle. The above stains are usually bleachable
stains.

21. Purpose of bleaching:
There are two purpose of using bleaching agent
• To remove the stain.
• To produce the high degree of whiteness in the laundry.
Nowadays modern optical brighteners are used to improve the whiteness in much simpler way with
less damage to the fabric.
Importance of correct bleaching process:
Incorrect bleaching process can do irreparable damage so correct use of bleach is very important to
avoid undue damage. Bleaches do not only attack stains, but also the fiber. Good bleaching process is
therefore characterized by a complete stain removal with the least possible damage to the fabric.
Bleaches cannot be added directly to the fabric. They must be diluted before.
The most common oxidation bleaches are:
Sodium per borate
Hydrogen peroxide
Sodium hypochlorite
Sodium dichloroisocyanurate
The first two are commonly known as OXYGEN BLEACHES
The last two are commonly known as CHLORINE BLEACHES
Bleaching with Sodium per borate:
• It is available in dry powder form
• It can be mixed with washing powder.
• It is always done in the main wash.
• All fully built detergent contains sodium per borate as the bleach component. These products
contains stabilizer.
• The process will begin at a temperature between 50 – 60 C & will reach its optimum at 85 - 90 C.
The bleaching time should be 10 minutes.
• The dose should be above 0.5 to 1.5 g/lit.
• The type of machines, as well as quality of water used can also affect the bleaching process when
using sodium per borate.

22. • All heavy metals ions act as catalyst for sodium per borate & speed up the release of oxygen. The
catalytic release can lead to textile damage.
Bleaching with Hydrogen Peroxide
• It is available in the liquid form.
• It is always done in the main wash.
• Concentration available is 30-50 % by volume.
• Its efficiency is identical to that of sodium per borate.
• The same criteria as described for sodium per borate.
Bleaching with Sodium Hypochlorite
• Chlorine bleaches can be applied in different ways as follows.
Chlorine bleach in pre-wash
• Chlorine bleach in the pre-wash has a time saving advantage, because a special bleaching cycle is
not required later in the wash process.
• Dosing: At 35-40 C, 10 min, 200 mg active chlorine / lit float.
At 60 C, 10 min, 120 – 140 mg active chlorine / lit float.
Chlorine bleach in the main wash
• Dosing: At 70 C, 10 min, 120 mg active chlorine / lit.
At 85 C, 10 min, 50-75 mg active chlorine / lit.
Chlorine bleach in the main wash
• Bleach can be added in the 2nd
& 3rd
rinse.
• Dosing: At 25-28 C, 7-8 min, 250-400 mg active chlorine / lit.
Neutralization of Chlorine Bleach
When using chlorine bleach one can only obtain a wash without chlorine smell and textile damage when all
chlorine residues are destroyed.
As anti-chlorine compound sodium Meta bi Sulphite is usually added which act as Neutralizer
Dosing: At 25 C, 7-8 min, 250-400 mg / lit
Bleaching With sodium Di chloro isocyanurate
This chemical is a chlorine carrier in powder form. The advantage lies in good storage stability, its means
that even for longer storage periods the full bleaching capacity is available. Most other chlorine bleaching
agent loose their strength during storage.
Methods of Removing Stain
Not all stains can be removed by washing & bleaching. Certain stains such as Rust, Fat, Mineral Oil,
Graphite & oil paints must be removed by a specific process & using specific stain removal agents. In
these cases we can only use chemicals and methods which do not damage the fiber or change the
color. Incorrect procedure can only cause more damage. It is therefore necessary to try the proposed
stain removal on a place on the garment where damage would be least noticeable.

Tips on Sorting :
• White washing is first separated from colored material.
• White washing is sorted according to the degree of soiling i.e. light, normal, & very dirty soiled.
• The colored washing is separated into light, medium & dark colored garments.
• Woolen is sort out separately as these should not be washed with white or colored washing.
• The following always wash separately
Mechanics overalls

24. Mixed overalls
Kitchen washing
Blood stained
Tips on Stain removal :
• Stain resistant to washing and bleaching can usually be removed by spot cleaning only.
• Spotting requires specific knowledge and time and is therefore expensive.
• Before starting any treatment it is important to recognize the type & origin of the stain.
• Removing stain is made even more difficult if the fiber is encrusted with lime deposit OR if the
stain is aged or fixed by wrong treatment e.g. blood. It is therefore important to spot stains when
they are fresh which means that the whole process must be geared for an optimal removal.
• After that we will have to follow the chart as per the type and origin of stain.
Detergent

How to remove the Stain ?
Step
1- To find the exact place of the stain.
2- To examine the size & # of stains.
3- To find the nature of stains.
4- Place the drops of appropriate spotting chemical on the surface of stain
5- Use the wooden and rub the stain gently.
6- Make sure that the wooden stick doesn’t have the sharp edges. Always use blunt area of the stick to
avoid damages.
7- There may be different kind of stain on the same fabric & there are different kind of chemicals
available for different stains so there is need to use chemical accordingly.
8- Use the steam with the help of spotting machine which have one steam gun and then dry with the
same gun, there is option available to use air also.
9- If the spot gone completely then there is only rinse the fabric with water only.
10- If the stain becomes light then repeat the same procedure.
11- If intensity of the stain remain same then don’t force it to remove from fabric just consult your
supervisor or in charge.
