 Main Tank: Main tank is the largest plant of the dyeing machine. This is the main
dye bath which contains the dye liquor and the fabric. The size of the tank depends
on the capacity of the machine. Liquor and fabric circulates in the main tank during
dyeing process.There may have different number of nozzle connected to main tank
according to the machine capacity.
Reel

Chemical Tank-2
Chemical Tank-1
 Reel: Fabric is loaded in the main tank using real. There is a motor attached to the
reel. It makes the loading process easy. Reel also used to unload the fabric from
tank after dyeing..

 Nozzle: Nozzle is the part of winch dyeing machine where dye pick up of the
fabric is maximum. After the winch the fabric is passed through the nozzle. Main
motor is connected to the nozzle and continuously circulate dyeing liquor to the
machine via nozzle. Fabric passed with the pressure of water and used for controlling
the speed of dye liquor. There is opening in the nozzle which can be controlled as
required.
 Panel Board: Panel board is attached to the main tank. By this board is used to
control the rpm, temperature, on-off of the machine.
 Monitor: Monitor is used to observe the process. Such as cheek water level,
temperature, pressure, dosing time etc. According to each bath data, machine sets all
the operation adjustment automatically by advanced Automation and Autosettings.
Thus, dye house supervisor is not involved to prepare any adjustments. As a result
machine always operates at optimum conditions, ensuring full batch to batch
repeatability
 Chemical Tank-1, 2: Chemicals are directly passed to the main tank by injecting
process. Injecting means to directly pass the liquor from dosing tank to main tank
without any time required i.e. to inject the liquor from dosing tank to main tank.
 Heat Exchanger: Heat exchanger is used for heating & cooling the dye bath liquor.
Heat exchange process is achieved by passing steam or water through the coiled
pipe line present in the heat exchanger. When heat is increased then steam valve is
opened and passed through the coiled pipe line and dyeing liquor is passed through
the heat exchanger. During the passage, heat increase of dyeing liquor. For reducing
heat, water valve is opened and heat will reduce.
 Heat Recover Box: A heat recover system is used here. This system uses temperature
of the waste water to heat up the fresh water. LAB-PRO is able to provide an overall
solution for the optimization of hot and cold water supply.

 Main Motor: Centrifugal pump is used for circulating the liquor through the
dyeing machine. Its capacity will depend on the capacity of the motor.
 Emergency Rod: Pulling the emergency rod stops the machine.
Emergency
Rod
 Filter Tube: Filter tube is used inside the circulating line and drain line through
which dyeing liquor is passed to filter impurities. If the filter is jammed then remove
from line cleaned.
Filter Tube

 Salt Dosing Tank: Salt is closed in this factory by linear process. Linear dosing
means to pass the liquor from dosing tank to main tank in a time equally. As for
example, if we want to pass 60g/l liquor in 30 minutes in linear dosing then we
will have to pass 2g/l per minutes.
Salt Dosing
Tank
 Drain Line: Drain line is used for extracting the liquor out of the dyeing
automatically.
Drain Line

 Winch: Winch is an important part of dyeing machine and used fir moving the
fabric through the whole dyeing machine. Winch is rotated with the help of motor.
Fabric is passed over the winch and fabric dwell time depends on the winch speed.
Winch speed will depend on the rope length and gsm of the fabric to be dyed.
There is opening on the machine for winch to removed tangled fabric from winch.
No. of nozzle per winch is normally 1 or 2 and total no. of winch per machine will
depend on machine capacity .
 Viewing Light: Viewing light is given in the dyeing machine to see how the dyeing
of the fabric is advancing in the dyeing machine from outside of the dyeing machine
as it is impossible to look in to the dyeing machine due to high steam temperature.
 Valves: Different types of valves are used in dyeing machine .Such as steam
valve, water valve, pneumatic valve etc.
 J-box: J-box of the machine is where fabric will stored after falling from the
nozzle. J-shape helps the smooth passage of fabric. This box contains a deposition
tube line attached to the fabric guide. This box is perforated and ensure easy
circulation of dyeing liquor to the machine.
 Additional Motor: Additional motor is used to dissolve salt, soda dye and other
chemicals. This motor is used in the dosing tank and there is an agitator
connected to the motor for additional power.

Production Planning Sequences & Operations
5.1 Production Planning Sequence in Mashriquee Textiles Limited:

5.1.1 Order Receive: For production any kind of Garment. At first we have to receive
order to execute production for any kind of RMG factory. After receiving orders, knit
composite factory plan how to execute order, which method they follow to execute order
and they also make for buyer approval as well as they also involve in material sourcing
process.
5.1.2 Planning: Here factory makes time and action plan based on man, machine, materials
availability or their capacity to accomplish order. In this stage, authority decides how to
accomplish the order, how much man, machine, material requires accomplishing order, how
to they control overall process etc.
5.1.3 Sampling: Here factory makes sample according to buyer requirements and send the
sample to the buyer for the buyer’s comments so that they can rectify the fault in the
sample.
5.1.4 PP Sample Approval: After getting the buyer comments, the factory rectify the
faults and send sample to the buyer again before going to the bulk production. That’s
why it is called pre-production sample.
5.1.5 Material Sourcing: In the mean time, factory will be involved in Material sourcing
process. At first they booked yarn to produce fabric in their knitting section. After
making fabric, the grey fabric sends to the dyeing section for dyeing according to the
requirements. After dyeing fabric & booking trims and accessories, stock up the fabric &
trims and accessories in the store and inspection the product.
5.1.6 Trims and Accessories: Factory must have to ensure trim and accessories are in
house before going to bulk production as per required quality and quantity.
5.1.7 Knitting: Here several steps are followed. Very First, yarn received from the
spinning mill, then dyed the yarn if required. After that, place the yarn cone in the creel
and feeding the yarn and knitting the fabric. After knitting fabric, withdraw fabric roll
from the machine and inspect the roll and give the roll number. So that, we can identify
the specific roll by the number.
5.1.8 Dyeing: After grey fabric knitting. Knitting section sends it to the dyeing section for
dyeing fabric roll according to required color. Before dyeing several stages have to be
maintained such as desizing, scouring, bleaching, mechanizing etc.
5.1.9 Storing: Before going to the bulk production, the factory have to ensure all the
equipment are available in store and store department inspect all the materials and makes
a summery about shade segregation, issuing product amount, sustaining balance and
closing the summery.
5.1.10 PP Meeting: Based on the planning, sample approval and material sourcing and
store department inspection report pp meeting are held to decide how to finally execute
the bulk production depends on what necessary step should be taken, how works will be
divided, section wise responsibility will be distributed through this meeting.

5.1.11 Cutting: As per PP meeting decision, cutting section received pattern as per style,
cutting ratio and then cutting master making the marker. After that fabric receive from
the store, fabric checking to see if it’s okay for cutting or not, then spread the fabric on
the cutting table and create lay, then marker on the lay and start cutting. After cutting
check the parts to see if there is any cutting fault or not, then numbering the cutting
pieces to avoid shade variations, then sorting & bundling the parts and send to the
printing and embroidery section if required or send to the sewing section for further
process.
5.1.12 Sewing Section: At this junction at first PP sample analysis is done, setup line
target, distribute process to the workers. Then cutting parts received from cutting or
printing/embroidery section and distribute the parts to workers in the same way as
process distribution and workers sewing the parts. In the mean time, line Q.C. check and
Q.C. audit has been occurred so that we can accomplish required quality. After that
finally counting output according to target and full garment quality ensuring is done and
garments are send to the finishing section.
5.1.13 Finishing Section: It is one of the most important part of this factory. After
inputing garments, first initial quality check is done to dind out the faults of the
garments. Here, spot removing, ironing/pressing, inspection, hang tag attach, get up change,
folding the garments as per requirements, poly the garments, metal checking etc are done
to give product aesthetic value. After that goods cartooning or packing to box is done
for buyer’s inspection.
5.1.14 Inspection: Buyer’s representatives or buyer inspect the cartoon randomly to find
out if the product produces according to requirements. If they find satisfactory result then
the goods will be accepted otherwise the entire shipment will be rejected.
5.1.15 Shipment: After inspect the goods as per predetermined condition, if buyer find
satisfactory result then the goods will be accepted for shipment otherwise the entire
shipement will be rejected.

5.2.2 Recipe Formulation :
Buyer can give fabric sample or color code, pantone number or spectral value (R%Value).
So at first the color is to identify if the buyer gives color code or pantone number. It is
easier to formulate recipe by spectrophotometer from spectral value because they are very
specific. But if it is a fabric sample then with the help of spectrophotometer several
number of recipes are to formulate.
5.2.3 Lab Dip Dyeing:
With these recipes several number of samples are to be dyed. We can dye 19 samples at
a time by a single dyeing machine (AHIBA IR Data Color machine).
5.2.4 Lab Dips Send to Buyer :
Now for every separate sample dyeing with separate recipe are send to buyer for approval.
The buyer approves one sample and the recipe of that approved sample is now send to
dyeing section.
5.3 Available Stock Solution:
Any concentrated dye solution (from 0.05% - 5.0%) can be obtained from ROBOLAB
machine. Because with the help of ROBOLAB machine up to 0.0001ml solution can be
obtained.

5.4 Calculation:
Usually following calculations are followed
Recipe Amount (gm/L) x Total Liquor
Soda = cc
1000 x Stock Solution %

Quality Assurance System
Introduction: The Quality Assurance Department is assigned to maintain consistently
uniform quality of the material in process and various stages of its manufacturing.
Mashriquee Textiles Limited is more about concern about quality. In this factory quality
assurance is more preferred than quality control, but both are in advancement.
After collecting fabric rolls from different machines, they are needed to be inspected or
assured required quality by the quality inspectors as if there were no big production
hampered and no complain from the buyers. Here are the details about it.
6.1 Objects And Scope of Quality Control:
Objects of Quality Control:
1. Research
2. Selection of raw materials
3. Process control
4. Process development
5. Product testing
6. Specification
Scope for Quality Control, Quality Assurance And Testing:
1. Testing Lab
2. Machine auditing system
3. A good training system

Quality Control in Grey Fabric Inspection:
Some points are needed to maintain for high quality:
1. Brought good quality yarn.
2. Machines are oiled and greased accordingly.
3. GSM stitch length, tension are controlled accurately.
4. Machines are cleaned every shift and servicing is done after a month.
5. Grey fabrics are checked by 4 point grading.
List of Equipment:
In this factory this is the list of equipments to assure quality:
1. Inspection m/c #1
2. Scissors
3. Electric balance
4. GSM cutter
5. Indication sticker
6. Measuring tape.
6.3 Quality Assurance Procedure:
1. Body & Rib Inspection: All rolls are kept in front of the inspection m/c time and
are inspected over the inspection m/c visually in a pre-set speed against light. For
any major minor faults like thick-thin, bare mark, fall out, contamination, fly, holes,
oil lines, needle line, slubs etc. are recorded in inspection report to classify the
fabric based on the four point system.
2. Collar & Cuff Inspection: Collar & cuff are inspected visually under the light box,
any major or minor faulty collar/cuff like having wrong ply, hole, needle line,
slubs, wrong design, first round problems etc. properly counted and recorded.

Quality Standard:
Mashriquee textiles Limited maintains the full ISO:9002 standard incase of quality. They
also posses SGS and oekotex certificate therefore, the 4 point system is followed to inspect
the body and rib fabric, the defects found and points given against are recorded in the
inspection sheet, following table shows the 4 point grading system followed by inspection
at Mashriquee Textiles Limited
Four Point Grading System
Size of defects Penalty
3 inches or less 1 point
Over 3 inch but not over 6 inch 2 point
Over 6 inch but not over 9 inch 3 point
Over 9 inch 4 point
Hole < 1 inch 2 point
Hole > 1 inch 4 point
The following formula is used for determining points 100sq.yds. in a roll of a fabric:
Points/100 Sq.yds. = (0.08*Roll points*A.GSM) / Roll wt. in Kg
Grading Calculation Based on Points:

6.4 Quality Control in Dyeing and Finishing:
The Mashriquee Textiles Limited assures the quality of the products of dyeing section in
the following three steps:
1. In laboratory
2. In dyeing section &
3. In finishing section.
Procedures are described below:
In Laboratory:
1. Swatch card from buyer according to requirement
2. Recipe prediction for sample dyeing
3. Sample dyeing until matching with swatch card.
4. Fastness & other tests of the fabric or yarn are done here.
In Dyeing Section:
1. According to the buyer’s sample, sample dyeing machine in dyeing shed & again
matched with the approved sample.
2. If result is OK, then bulk production.
3. During dyeing, samples are taken until accurate shade matching. The interval may
be 30-40 minutes.
4. After dyeing sample is collected after softening is done.
5. Last off all, sample is collected after fixaton & matched.
6. Then allowed the fabric to be finished.
In Finishing Section:
1. By using a series of finishing machines correct width, softness & appearance are
maintained according to requirements.
2. Then sampling is done for several times to test GSM, Shrinkage & fastness properties
3. Finally fabric is inspected & prepared for delivery.

Maintenance
Maintenance is considered as important as other engineering functions. It makes
responsible for provision of a condition of machine, buildings and services that will
permit uninterrupted implementation of plans requiring their use.
7.1. Objectives & Maintenance of Machinery
Objectives of Maintenance:
1. To keep the factory-plants, equipment, machine tools etc. in an optimum working
conditions.
2. To ensure specified accuracy to products and time schedule of delivery to
customers.
3. To keep the down time of machines to the minimum thus to have control over
the production program.
4. To keep the production cycle with in the stipulated range.
5. To modify the machine tools to meet the augmented need for production.
6. To improve productivity of existing machine tools and to avoid sinking of
additional capital.
7. To reduce the maintenance costs as far as possible thereby leading to a reduction
in factory overheads.
8. To prolong the useful life of the factory, plant and machinery, while retaining their
acceptable level of accuracy of performance thus avoiding or prosponding
incurring of heavy capital expenditure involved in their replacement.

Maintenance of Machinery:
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.
Breakdown Maintenance:
In this case repairs are made after the equipment is out of order & it can not perform
its normal functions.
Routine Maintenance:
Maintenance of different machines are prepared by expert engineer of maintenance
department. Normally in case of dyeing machine Maintenance after 30 days complete
checking of different important parts are done.
Economic Considerable of Maintenance:
1. It is very profitable activity & ensures maximum productivity at minimum costing.
2. It improves product quality.
3. It ensures less time to produce a specific product.
4. It improves machine accuracy.
5. It maintains a long life of the machine.

Maintenance Flow Chart:
Manpower Set-Up For Maintenance:
1. A Shift 7 AM-3 PM
2. B Shift 3 PM-11 PM
3. General Shift 9 AM- 6 PM
7.2 Functions of Maintenance Personnel:
1. Inspection or Check-Ups:
1. External Inspections: Watching and detecting defects form abnormal sound,
vibration, heat, smoke etc. when machine is in operation.
2. Internal Inspections: Inspection of parts such as gears, bushes, bearings, tolerances
in the parts etc. when machine is under pre-planned shutdowns.
3. Inspections of Important Machines: Machines which can disrupt whole of the
production, are delicate and require much time for the repair. Attentions are given
for inspection of these machines and schedule for inspection, cleaning lubrication
are done rigidly.
4. Inspection of Ordinary Machines: Frequency of inspection of ordinary machines
is kept as low as they do not affect the production.
5. Lubrication: Mechanical components like gears, bearings, bushes and other friction
surfaces etc. give good performance for long periods when they are systematically
lubricated. Systematic lubrication means the application of right type of lubricants
at the right time, at right place and in right quantity. For lubrication, a lubrications
schedule should be prepared and that should be followed strictly. Here lubrication
is done whenever is needed.

6. Planning and Scheduling: Every preventive maintenance work should be pre-
planned in detail on the basis of the analysis done on the past records. A
scheduled programme thus prepared should be followed strictly. Thus programme
should be in detail specifying the point-requiring daily, weekly, monthly, half yearly
or yearly attention.
7. Records and Analysis: Good record keeping is essential for good maintenance, as
it helps in for casting maintenance. For this purpose following records are generally
maintained:
1. Operation manual
2. Maintenance and instruction manual
3. History Cards and History registers
4. Spares Procurement Registers
5. Inspection Registers
6. Log books
7. Defect Registers etc.
1. Training of Maintenance Personnel: For the success of maintenance a sound
training is essential for the maintenance personnel. Hence the technicians and
supervisors are trained to carry out maintenance, inspection and repaired in a
systematic way.
2. Storage of Spare Parts: Sometimes machine remains idle for want of spare parts
for considerable time and thus it affects considerable loss of production. Hence it
is essential to keep the spare parts so as to avoid loss of production.
