Numbering.
Knitting:
Knitting is the method of creating fabric by transforming continuous strands of yarn into a series of
interlocking loops, each row of such loops hanging from the one immediately pre -ceding it. The basic
element of a knit fabric structure is the loops intermeshed with the loops adjacent to it on both sides
and above and below it.
The weft knitted structure is very different from the warp knitted one. The difference is apparent from
both warp and weft knitted structures is shown in simplest forms in below. It is seen from this figure
that in a knitted structure a horizontal row of loops can be made using one thread and the thread runs
in horizontal direction
In a warp knitted structure, each loop in the horizontal direction is made from a different thread and the
number of threads used to produce such a fabric is at least equal to the number of loops in a horizontal

row. One can say that in a warp knitted fabric the threads run roughly in a vertical direction.
Parts of knitting Machines:
Creel: Creel is used to place the cone of yarn.
Feeder: Feeder is used to feed the yarn to make a fabric.
Tensioning device: Tensioning device is used to give proper tension to the yarn.
VDQ pulley: VDQ pulley is used to control the GSM by controlling the stitch length.
Guide: Guide is used to guide the yarn.
Sensor: Sensor is used to seen & the machine stops when any problem occurs.
Spreader: Spreader is used to spread the knitted fabric before take up roller.
Take up roller: Take up roller is used to take up the fabric
Fixation feeder: These types of feeder are used in Electrical Auto Striper Knitting Machine to feed the
yarn at specific finger.
Rethom: These devise are used in Electrical Auto Striper Knitting machine.
Design Development by using CAM:
The type of fabric to produce depends on the setting of the Cam of Knitting machine. The different types
of fabric can be produced by only changing the cam setting. The cam settings to produce di fferent fabric
are given below:
Single jersey:
Only knit cams are used to produce single jersey fabric. So the setting would be-

K K K
K K K
K K K
Inter lock:
Inter lock fabric is produced by using knit and miss cam. So the setting would be-
K M K
M K M
Lacost:
Lacost uses knit and tuck cam like-
K K T K K
T K K K T
French terry:
The cam setting is as follows-
K M K M K M
K T K M K T
K M K T K M
Considered point of Knitting:
When a buyer orders for fabric then they mention some points related to production and
quality. Before production of knitted fabric, these factors are needed to consider. Those are as follows-
• Finished G.S.M.
• Type of Fabric or design of Fabric.
• Yarn count
• Types of yarn (combed or carded)
• Diameter of the fabric.
• Stitch length

• Color depth.

Production Calculation:
A. Production/shift in kg at 100% efficiency
B. Production/shift in meter

C. Fabric width in meter:
D. Needle calculation:
For Circular knitting machine:
Diameter of the Machine X Gauge of the Machine X 3.14
For example: Diameter of the machine is 18” and Gauge of the machine is 24. Then the number of
Needles on the machine would be-
18 X 24 X 3.14 = 1356
For Flat Bed knitting machine:
Length of the Machine needle bed X Gauge of the Machine
For example: Length of the machine needle bed is 56” and Gauge of the machine is 14. Then the number
of Needles on the machine would be-
56 X 14 = 1568
Faults of Knitting:
1. Hole Mark
Causes:
Holes are the results of yarn breakage or yarn cracks.
During loop formation the yarn breaks in the rejoin of the needle hook.
If the yarn count is not correct on regarding structure, gauge, course and density.
Badly knot or splicing.
Yarn feeder badly set.
Remedies:
Yarn strength must be sufficient to withstand the stretch as well as uniform.
Use proper count of yarn.
correctly set of yarn feeder.

Knot should be given properly.
2. Needle Mark
Causes:
when a needle breaks down then needle mark comes along the fabrics.
If a needle or needle hook is slightly bends then needle mark comes on the fabrics.
Remedies:
Needle should be straight as well as from broken latch.
3. Sinker Mark
Causes:
When sinker corrode due to abrasion then sometimescannot hold a new loop as a result sinker
mark comes.
If sinker head bend then sinker mark comes.
Remedies:
Sinker should be changed.
4. Star Mark
Causes:
Yarn tension variation during production.
Buckling of the needle latch.
Low G.S.M fabric production.
Remedies:
Maintain same Yarn tension during production.
Use good conditioned needles.
5. Drop Stitches
Causes:

Defective needle.
If yarn is not properly fed during loop formation i.e. not properly laid on to the needle hook.
Take-down mechanism too loose.
Insufficient yarn tension.
Badly set yarn feeder.
Remedies:
Needle should be straight & well.
Proper feeding of yarn during loop formation.
Correct take up of the fabric & correct fabric tension.
Yarn tension should be properly.
6. Oil stain
Causes:
When oil lick through the needle trick then it pass on the fabrics and make a line.
Remedies:
Ensure that oil does not pass on the fabrics.
Well maintenance as well as proper oiling.
7. Rust stain
Causes:
If any rust on the machine parts.
Remedies:
If any rust on the machine parts then clean it.
Proper maintenance as well as proper oiling.
8. Pin hole
Causes:
Due to break down or bend of the latch, pin hole may come in the fabric.

Remedies:
Change the needle
9. Grease stain
Causes:
Improper greasing
Excess greasing
Remedies:
Proper greasing as well as proper maintenance
10. Cloth fall- out
Causes:
Cloth fall- out can occur after a drop stitch especially when an empty needle with an empty
needle with closed latch runs into the yarn feeder and remove the yarn out of the hook of the following
needles.
Remedies:
Make sure all the latches of needle are closed with feeding yarn after a drop stitch.
11.
A fault in weft knitted fabric appearing as light or dark course wise(width wise) Stripe.
Causes:
This fault comes from yarn fault.
If different micro near value of fiber content in yarn.
Different lusture, dye affinity of fiber content in yarn.
During spinning different similar classes of fiber is mixed specially in carded yarn & these fibers
have similar characteristics.
In draw fame different similar classes sliver is mixed and make one sliver.
Remedies:

We can use this fabric in white color.
12. Fly dust:
Causes:
In knitting section too much lint is flying to and fro that are created from yarn due to low twist
as well as yarn friction. This lint may adhere or attaches to the fabric surface tightly during knit fabric
production.
Remedies:
Blowing air for cleaning and different parts after a certain period of time.
By cleaning the floor continuously.
By using ducting system for cleaning too much lint in the floor.
Over all ensure that lint does not attach to the fabric.
13. Yarn contamination
Causes:
If yarn contains foreign fiber then it remains in the fabric even after finishing,
If lot, count mixing occurs.
Remedies:
By avoiding lot, count mixing.
Fault less spinning.
13. Yarn Faults:
Neps.
Slubs.
Yarn count variations.
Thick/Thin place in yarn.
Hairiness
Flat Knitting Machines Fault:

10 Flat Back Rib
Knitting Parameter & Calculation: The main parameters & calculations are
followed in knitting section, are given below-
GSM: GSM means the weight in gram of one square meter fabric. Mainly it is measured by
GSM cutter & electric balance.
Gauge Selection
Selection of machine gauge depends upon yarn diameter. Yarn diameter also depends on several
factors such as yarn count, fibre type, yarn finishing etc. general practice of yarn count and
machine gauge in different industries in Bangladesh given below:
Yarn count used Machine gauge Yarn count used Machine gauge
16 18 28 22
18 20 28 25
20 20 28 28
20 24 30 22
24 22 30 24
24 24 30 28
26 20 30 34
26 22 34 28
26 24 34 28
26 28
The above values may differ, because it is the results of a research work. There is a relation
between yarn in tex and machine gauge is given by equation,
The yarn count to be used on a circular knitting machine depends largely on the pitch, and thus on the
machine gauge. For any given machine gauge it can lie within a larger range, be-cause on the same
machine different yarn counts can be used, depending on the knitted structure, thedesired optics (fabric
appearance) and the fabric properties.

Loop or Stitch Length:
The length of yarn knitted into one stitch in a weft knitted fabric. Stitch length is theoretically a
single length of yarn which includes one needle loop and half the length of yarn (half a sinker
loop) between that needle loop and the adjacent needle loops on either side of it. Gen-erally, the
larger the stitch length the more elastic and lighter the fabric, and the poorer its cover opacity and
bursting strength.
Stitch Length, l = One needle loop + Two half a sinker loop Yarn count is a numerical
expression of fineness or coarseness of yarn), from the centre of a needle to the centre of the
neighboring needle express in mm.
Yarn count:
Yarn count is calculated in two systems:
Direct system
Indirect system
Production Calculation:
It has been expound in the sections above that the output of a circular knitting machine de-pends
on a series of different influencing variables. A wealth of machine data and data on the fabric to
be produced is required for calculating production capacity.
In this respect the cylinder diameter d in inch, the gauge E, the system count S, the machine rpm
n, and the efficiency level ɳof the circular knitting machine must be known. The following data
on the fabric produced must also be available:
The construction (e.g. single jersey, rib, purl etc.)
The course density or course /cm and the weight per unit area in gm/m
2
.

Knitting Procedure forElastane Single Jersey Fabric:

Knitting Procedure for Single Jersey Fabric (Without Elastane):

Gray Fabric Inspection:After knitting every roll of grey fabric of each order is inspected for
checking “is it meet with the finishing target or not.” Four point method was used for inspection the
fabrics. Four grey fabric inspection reports for different four orders are given below-

Dyeing Parameter & Calculation:
The things which influence the effective coloration of textile materials with reactive dye are
called as parameters of dyeing. These include –Temperature, Time, Liquor ratio, pH of the bath
etc. A brief description about them is given below-
Effects of Temperature:
Temperature of the dye bath plays vital role for dyeing. Rise in temperature has a large effect on
an increase in the diffusion rate of dyes into fabrics. Increasing of temperature increases the rate
of dyeing & of the dye migration. Higher dyeing temperature ensures the good leveling & better
penetration of dye in to the fibers. But the temperature depends on the types of dyes adapted in
the dye bath. For Example-in case of hot brand dyestuff the dosing temperature of dye is 80ºC
and for cold brand dye temperature is kept 60ºC.
Effects of pH:
In the case of most popular fiber reactive dyes, a high PH actually activates the cellulose (cot-ton)
fiber, forming a cellulosate anion, which can then attack the dye molecule, leading to a
reaction that produces a strong, permanent covalent bond. Without a high pH, the dye will not fix
permanently to the cellulose fiber. For this reason Sodium Carbonate (Na2CO3) [Some time
mixed alkali such as (NaOH + Na2CO3)] is used for no other reason than to increase the PH of
the dye reaction, so that the fiber will react with the dye. Basically during the color addition, the
PH of the bath remains at near about 6, but after adding alkali it goes rise to pH.
11.4 & this is the critical stage in which the dye molecules fix up with the fiber.
Effects of Material: Liquor Ratio (M: L):
Dye bath exhaustion increases with the decreasing of liquor ratio. Dyeing at low liquor ratio
decreases the amount of waste dyes & chemicals in the effluent. Because higher the liquor ratio
greater the amount of g/l of chemicals which increases the volume of effluent. To get rid from
this problem Then Air flow Dyeing machine is getting popular in our country which can dyeing
at 1:3 Materials: Liquor ratio. But in case of These Jet Dyeing machine it can possible up to 1: 5
Materials: liquor ratio.
Effects of Time:

The time for dyeing also the vital one. A specific Time adjusted with the temperature, very much needed
for better dyeing. For this reason color dosing takes place in 20 minutes (may vary process to process) &
Specific run time is set for dyeing.
Shrinkage
A dimensional change resulting in a decrease in the length or width of a specimen subjected to
specified condition is known shrinkage.
Spirality:
If the wales of the knitted fabric are not perpendicular to the course and skew to the right or left
spirality occurs in the fabric. This creates serious problem, especially in the apparel industry.
Dyeing Laboratory:
Laboratory:
Lab is the most important section of a dying industry. Higher precision lab can aid easily to
achieve the goal of the organization. Before bulk production a sample for the approval from
industry is sent to the buyer. As per requirement of the buyer the shade is prepared in a lab
considering the economical aspect.
The Main Objectives of a Textile Dyeing Laboratory:
To develop standard operating procedures (SOP) for all the products which are to be
processed in a dye house.
Dyestuffs evaluation.
Color matching together with process and product development.
To provide training ground for production and laboratory technicians.
Process optimization and cost reduction through process modifications and develop-ing
or testing newer techniques and products.
In process checks of important quality parameters affecting the quality, efficiency, cost
etc and monitoring.
Quality control of all raw materials consumed and also all processed material in terms of color and
fastness.

construction (single jersey, Rib, Lycra Rib, Lacost, PK etc.)
To send the grey fabric to the dyeing floor with batch card.
To keep record.
Proper Batching Criteria:
To try same rope length for each nozzle.
To use maximum capacity of existing dyeing machine.
To minimize preparation time & machine stoppage time.
To use a particular machine for dyeing same shade.
Turningmachine:
This tubular turning machine is for turning tubular knit fabric before dyeing and drying after. As
knit fabric material is handled by the air force, there is no fear of damage during operation.
Speciation:
Made of stainless steel, the main pipe can stand up permanently without rusting.
Operation is easy and safe.
Air flow initiation or termination is instantly effected by the press of the ON or OFF
push-button, or the moment the material fabric reaches the eject roller.
There is no lingering air consumption.
Air flow direction is designed to automatically switch upon alteration of the position of
the curved pipe, as they are interlocked with each other.

Function of machine parts:
J-Box: Squeeze the fabric to reduce the water contains. Water reducing percentage
depends on J-Box pressure.
De-twister: By the de-twister rope formed fabric become untwists form. (due to action of
sensor)
Hand Wheel: It is manual and used for guiding the rotary blade.
Turn Wheel: It controls the fabric rotation
Rotary Blade: To cut the fabric through break wales line.
Ring: To help cutting.
Guide Roller: To guide the fabric to plaiting
Plaiter: To plait the fabric.
Sensor: Sense for cutting through break wales line.

Basic Operation Principle:
The bianco tensionless tubular fabric slitting and opening lines are used after the wash process or
the dyeing station.
1 The fabric, placed in a basket in rope form.
2 It is made to pass through the squeezing unit where most of the impregnation liquid is
extracted.
3 Then it enters the de-twister, which eliminates the tension of the rope and is prepared for
the slitting and spreading processes.
4 The container is placed on a platform whose rotation, synchronized with the action of the
de-twister, untwists the rope preceding the entrance to the de-twister.
5 The latter is placed at the top of the structure, for optimal distance from the automatic
slitter, so as to enhance the effectiveness of rope de-twisting and spreading.
6 Then the untwist form fabric is transferred to the basket by means of motorized belts and
then it moves on towards the slitter without stresses that would can be widened upto a diameter
of 80 cm.
Pick the fabric leaving the tensionless basket and with the aid of a
beater,plaints it on to the conveyor belt making for enhanced relaxation of the
fabric.
The cutting line can be controlled by means of basket rotation.
1 From conveyor belt fabric is passed through dogal centering roller (It constitutes a
compacata fabric centering system, with faster centering action and enhanced efficacy compared
to traditional centering devices.)
2 The open with fabric is passed through squeezing system to extract the greatest possible
quantity of impregnation liquid from the fabric, by squeezing it between two rubber coated
rollers. (It structure is highly compact and sturdy, and it can be made either of iron or of stainless
steel).
3 After squeezing the fabric it go to the plaiter to plait on a trolley.

Basic Working Principal of Stenter:
The stenter line has units: 2 padders, 1 weft straightener, 1 tenter and drying chambers. There are
also steaming, selvedge degumming and curing arrangement. At least padder is simply wash
with water. The squeeze pressure normally 5 bars. In two padder the fabric is treated with
softener. The fabric is passed through tenter. There are two steams along fabric width that apply
steam from below fabric. There are gumming unit before drying chamber. In sten-ter, fabric
enters in drying chambers by gripping with chain pin and with over feed/ under feed that is with
more controlled conditions. The drying chamber has 7 units. Generally tem-perature kept about
150 – 200 ºC. The fabric comes out form chamber by tenter chains grip-ping with pins. Before
delivery the fabric is removed from the tenter chains by unpinning rollers and then the cutting
units cut the additional fabric from the gummed sides. Now at de-livery side there is an antistatic
arrangement to remove static electricity from heated

SEWING THREAD

Types of Sewing thread being used in the garments industry of Bangladesh-
1. Polyester Core spun Thread.
2. Spun Polyester Thread.
3. Staple Spun Cotton Thread.
4. Textured Polyester Thread.
5. Polyester Cotton Core spun Thread.
6. Trilobal Polyester Thread.
1.PolyesterCorespun Thread:
This is more costly thread. This type of thread is produced by spinning staple polyester fibre
around a core of high tenacity continuous filament polyester in yarn-spinning operation. Two or
more of these composite yarns are then twisted together to give the necessary size and tensile
strength. e.g. Epic(Coats).
Staple polyester filament
Core polyester filament
Uses: Mainly used in topstitching of shirts, blouses, trousers, sportswear, jeans & work clothes
etc.
Advantages:
o Exceptionally strong.
o Its resistance to abrasion helps ensure long seam life in a wide variety of
materials.
o Fine threads can be used for delicate fabric without compromising on strength,
thereby avoiding problems like seam pucker

2. Spun Polyester Thread:
Staple polyester fibres are spun into polyester yarn. Then two or more of spun polyester yarns
are twisted together to produce spun polyester thread.
e.g. Astra (Coats)
Advantages:
o 1.High tenacity of polyester ensures greater strength and thereby high
abrasion resistance.
o 2.Very least amount of shrinkage (less than 1%) compared to cotton thread.
Uses: Mainly for over-edging. Also used for general seaming of shirts, trousers, knitwear,
jackets, blouses etc.
3. Staple Spun Cotton Thread:
Normally long staple cotton fibres are spun into cotton yarn. Then two or more ply of spun
cotton yarn are twisted together to produce spun cotton thread.
e.g. dymax (Coats)
Advantages:
o 100% cotton thread have relatively low strength and elongation compared to
those in synthetic thread, therefore they need relatively light sewing tension
and high stitch densities.
o B. Very high amount of shrinkage compared to synthetic thread.
Uses: Mainly used in sewing cotton garments that are to be post dyed.
4. Textured Polyester Thread:
Made from textured continuous polyester filament.
(Note- texturing means modification by applying crimp to thefilament) .e.g. Gramax (Coats).

Advantages:
o 1.Provides high softness and comfort.
o High extensibility and seam strength enhance higher seam security.
Uses: Mainly used in “next to the skin” seams for high softness .e.g. under ware, swimwear,
baby wear, Also widely used in over-locking and covering stitches for high extensibility and
seam security.
5. Polyester Cotton Core spun Thread:
A Made of polyester filament in the core and staple cotton fibre which wraps polyester filament.
Two or three plies of this yarn are twisted together to make thread.
e.g. dual duty (Coats).
Advantages:
o This thread has been developed to improve the properties cotton and to get the
opportunities of both cotton and polyester fibre.
o Very low shrinkage, good strength and cotton core protects poly core from needle heat
and high ironing temperature.
Uses: fine cotton denim shirt , outdoor wear etc.
6. Trilobal Polyester thread:
Newly developed polyester fibre to improve the dullness of usual polyester fibre.Trilobal poly is
a multiple filament, twisted, high-sheen continuous fiber thread. It has the bright appearance of
rayon or silk. Triangular shaped fibers reflect more light and give an attractive sparkle to
Uses:embroidery for garment.
PACKING INTO CARTON

Effluent Treatment Plan:

Process description
The effluent from different sources will be collected in an Equalization tank through a Bar
Screen. Bar Screen will remove large floating materials. The equalized effluent is then pumped
to a Flocculation tank. Coagulation agents, like Lime, Alum and Polyelectrolyte will be dosed in
the Flocculation Tank to agglomerate the suspended particles. The effluent from this tank will
pass through the Primary Tube Settler where flocks are removed. After primary tube settler, the
effluent flows to the Aeration Tank, where BOD & COD are removed. The pH of the effluent
will be corrected to bring to the level of 8 to 8.5. After Aeration Tank, the effluent will pass
through a Secondary Clarifier where suspended biological solids are re-moved. From Secondary
Clarifier, the effluent will be discharge to drain.
Sludge generation from primary clarifier will be taken to sludge pit or sludge drying bed. From
sludge pit sludge will be fed to centrifuge followed by filter press unit. Sludge cakes generation
from filter press will be dried and can be disposed suitably. Sludge from second-ary clarifier will
be re-circulated back to aeration tank and periodically to sludge pit.
Water treatment plant:

Water for a textile plant may come from various sources .These includes surface water from
rivers and lakes, and subterranean water from wells.
The various salts present in water depend on the geological formations through which the water
has flowed. These salts are mainly the carbonates (CO3
2-
), hydrogen carbonates or bicarbonates (
HCO3
-
), Sulphates ( SO4
2-
) and chlorides ( Cl
-
) of calcium ( Ca
2+
), magnesium (Mg
2+
) . Although
calcium and magnesium carbonates in limestone are relatively insoluble in water. So in this
reasons, water hardness can be divided into two ways
1) Temporary hardness:Ca(HCO3)2 , Mg(HCO3)2 , Fe(HCO3)2
2) Permanent hardness:CaCl2 , CaSO4 , Ca (NO3)2 , MgCl2 , MgSO4 , Mg(NO3)2
This water hardness causes some serious consequences in a textile dyeing and finishing
Industries and these are
1 Precipitation of soaps.
2. Redeposit ion of dirt and insoluble soaps on the fabric being washed,
a. this can cause yellowing and lead to uneven dyeing and poor handle.
2 Precipitation of some dyes as calcium and magnesium salts.
3 Scale formation on equipment and in boilers and pipelines.
4 Reduction of the activity of the enzymes used in washing.
5 Incompatibility with chemicals in finishing recipes and so on.
Hardness expressed by parts per million (ppm) of CaCO3 which is standard hardness scale
and it is also called American hardness.
Capacity: 1200000 Liter
Per dayAverage used 110000 liter and H2SO4 is used 150-200 liter.

Maintenance
Maintenance is a procedure by which Maintenance is a process by which equipment is looked
after in such a way that trouble free. Service and increased machine life can be ensured and
specific product quality required by the customers is sustained. Maintenance of machinery is
very important for proper working of machine.
Objective of Maintenance:
To ensure specified accuracy to product & time schedule of delivery to customer.To keep the
machine down time to minimum thus to have control over the productionprogram.
To keep the production cycle within the stipulated range.
To modify the machine settings to meet the need for the production.
There are Three Types of Maintenance
Preventive Maintenance:
Preventive maintenance is a predetermined routine actively to ensure on time inspection /
checking of facilities to uncover conditions that may lead to production break downs or harmful
description
Break down maintenance:
In this case, repairs are made after the equipment is out of order and it cannot perform its normal

functions.
Routine Maintenance:
Maintenance of different M/Cs is prepared by expert engineer of maintenance department.
Normally in case of dyeing m/c maintenance after 30 days complete checking of different
important parts are done.
OKTL have brake down maintenance;in hear this dept. is so week. All kind of maintenance work done by
this people but no of worker is not enough in this department.
Conclusion:
Technical education and its adoption in practical field,inextricably, without the implementation
of the knowledge gathered in technical education its success bound to suffer. Therefore, this two

months long industrial as a partial fulfillment of our B.Sc. in textile Engineering course helped
us to accomplish the gap between the theoretical and practical knowledge by providing an
elementary idea about industrial environment processing machines, tools, equipment’s
production system and maintenance , administration and management system .
We completed our industrial training at Orion Knit Textiles Ltd. It was established just a few
years ago with latest model of different machinery within a very short time it earned name and
fame at home and abroad for its quality in production and administrative facilities. The industry
has been a setting up of a 100% export oriented composite knit garment unit. The project is set
up with Knitting, Dyeing finishing and garments facilities.
Two month is not long period and it not sufficient time to learn all area in a factory but can
achieve an idea and can introduced with factory environment. In factory all the employs were
very busy to his/ her own responsibility, so they cannot supervise us properly, but they were very
cordial to us.Orion Knit Textile Ltd. also called a training house of Textile Engineer.
At our training period we gather some knowledge which can be play a vital role in our pro-fissional
life. Beside the theoretical knowledge, by industrial training a student can increase
his/her knowledge properly. At training period if a student can supervise by a experience person
at industry with university he can appropriately learn vast knowledge. We successfully
completed our training, we try to gather all necessary information but it is true that within this
short period it is quiet impossible to achieve 100% success but as a whole this industry training
was a satisfactory one again I would like to thank the authority of Orion Knit Textile Ltd. as well
as my honorable teachers for their altruistic help and advice .
Some Suggestion for Orion Knit Textile:
1. All Interne student not proper support from OKTL employee so OKTL people not proper
instruction for interne student as a result they are some missing gathers knowledge.
2. Sometimes we are facing electricity problem so I think this problem solving process is
another electricity line.
3. Proper man power problem because OKTL have not sufficient skilled man power.

4. OKTL lab have not sufficient instrument as a result OKTL missing some order.
5. OKTL factory space is big but they are not enough machines for production as a result they
are some missing big order.
6. I think OKTL marketing team is very slow as a result they have not catching direct buyer if
marketing department change they are working policy I think they are catch buyer directly.
7. Not enough certificates& membership in OKTL,I think more certificates& membership is
important for big order.
8. ETP plant will use more chemical for better neutralization of ETP water.
