Introduction
Industrial attachment is an essential part of four years B.Sc. in Textile
Engineering course of Bangladesh University of Business And Technology.
We had the opportunity to perform the industrial attachment with Knit
Concern Ltd.
The industrial attachment is the most effective process of achieving the
practical experience. It provides us sufficient practical knowledge about
management, evaluation, productivity, production planning & control,
Production cost analysis inventory control, purchasing. Utilities and
maintenance of machinery and their operation technique etc.
As a textile engineer we should have an experience in the study of Wet
Processing technology, machineries products and overall situation of the
factory before work in the industries.
During 2 month long attachment, we studied the man, machine, material
aspects of the Circular & Flat knitting section, quality control section,
planning section, grey fabric inspection, finished fabric inspection, dyeing &
finishing section of the mill. According to our studies there we have prepared
the following report and would like to present.

Process description

22 | P a g e
Pretreatment:
Pretreatment is the preparation period of fabric from dyeing. For getting proper fastness of fabric
and proper dyeing pretreatment is a mandatory process.
Scouring:
The process to remove fats, oil, waxy substances and added the impurities by certain percentage of
alkali treatment and which increase the absorbing power of the textile units, is called scouring.
Bleaching:
The process by which the natural color of a fiber can be removed and make the textile this pure
white and bright is called Bleaching.
Dyeing:
Dyeing is a method which imparts beauty to the textile by applying various colors and their shades
on to a fabric. Dyeing can be done at any stage of the manufacturing of textile- fiber, yarn, fabric or a
finished textile product including garments and apparels. The property of color fastness depends
upon two factors- selection of proper dye according to the textile material to be dyed and selection
of the method for dyeing the fiber, yarn or fabric. After dyeing, dye molecules have uncut chemical
bond with fiber molecules. The temperature and time controlling are two key factors in dyeing. Fakir
Knitwear’s Ltd., they used to do knit fabric dyeing and knit garments dyeing.

C. Disperse dyes have as conic groups and are insoluble in water. With the help of a dispersing
agent dyes can be dispersed in the dye bath. Reduction clearing is done in case of medium and deep
shade only to improve the wash fastness. This high temperature process is
Nontoxic and hygienic process. At high temp like 1300
C acid getting weaker so for getting PH 4.5
Butter solution is used in polyester dyeing process and it is strong acidic along with dispersing agent.

PROBLEMs ENCOUNTERED IN DYEING:
Uneven Dyeing
1. It can be caused due to rapid addition of dyes and chemicals. For this purpose the dosing
of soda ash should be maintained properly.
2. Pressure difference.
3. Over loading in the m/c.
4. Yarn lot mixing.
5. Improper control of temperature.
6. Less amount of leveling agent.
7. Improper pretreatment.
Uneven Shade in Rope to Rope
Improper rope length in each chamber.2. Improper fabric flow speed in each nozzle.
Off Shade
1. Improper M: L ratio.
2. Lower amount of auxiliaries.
3. Improper mixing of dyestuffs.

38 | P a g e
Dye Spots
This is most common fault caused by operator not correctly mixing and thoroughly dissolving
dyestuffs in the right amount of water.
Batch to Batch Shade Variation
If any of parameters of dyeing are changed then it will produce problems in batch to batch
consistency. In order to avoid this defect the following steps should be followed-
1. Maintain the same liquor ratio.
2.Check that the fabric has the same dye affinity.
3. Use the same standard program procedures for each batch.
4. Making sure that the operators add the right bach of chemicals at the same time
& temperature in the process.
5. Check the water supply daily especially, hardness & Na 2 CO 3 content.
Crease Mark
Causes:
1. Poor opening of the fabric rope
2. Due to high speed of machine running
3. Unequal pump pressure and reel speed
Running Marks
Running marks are frequently related to the material construction and are caused by poor opening of
the fabric rope.
1. Reducing the machine load and running at a slightly higher nozzle pressure, or using the next
largest available nozzle size, may also help.
2. Either pre setting or pre relaxation of the fabric before dyeing can avoid this problem.
3. Running and crack marks can also be a result of incorrect process procedures. A higher fabric
speed, combined with slower rates of rinse and cooling will often correct the problem.
4. Care should be taken to check that bath draining temperatures are not very high especially
viscose blends are involved.
5. Shock cooling of static material will also cause crack marks. Running marks are frequently
related to the material construction and are caused by poor opening of the fabric rope.
Intensive Foaming
In case of intensive foaming, which is caused when; the pumps try to pump admixture of air and
water. This resets in the loss of nozzle pressure & floating of flake. If the foaming is severe it is
better to drop the bath & restart the process, after adding an anti foaming agent to the new bath.
Patchy Dyeing
It is caused, if dye solution is not correct and also scouring is improper.

39 | P a g e
Miscellaneous Problems
Batch to batch processing may vary due to the improper calculation of dyes and chemicals and
improper strength of salt soda and H2O etc. Beside hardness of water and caustic may lead to an
improper shade.
Process of Shade Matching:
The required shade provided by the buyer is reproduced in the lab in lab dyeing machine after the
recipe prediction. The lab in-charge first uses the Computer Color Matching System, to obtain the
closest shade match recipe. Then he consults the shade card and Pantone book to verify the obtained
recipe. If he thinks that certain changes in the recipe is necessary, he then alters the recipe according
to his experience. This recipe is used to dye a sample of 5 gm fabric in the lab dyeing machine with
following parameters.
a) Temperature and time 
Cold Brand Reactive Dye-65c temp;
60 minHot Brand Reactive Dye-98c temp;
60 min Turquoise Color (Cotton)-85c temp;
60 minPolyester-130c temp; 30 min
b) M:L ratio 
The samples are usually dyed using 1:15 ratio.

MAINTENANCE

45 | P a g e
Maintenance of Machinery:
Maintenance of machinery is very essential mechanical effort for achieving smooth running of
different machines. Maintenance is a process by which equipment looked after in such a way that
trouble free services and increased machine life cane ensured and specific product quality required
by the customers is sustained. Onetime maintenance increase m/c lifetime & ensures trouble free
services.
In Landmark Textile Mills Ltd. 2 types of maintenance are done
1. Break down maintenance
2. Routine maintenance
1. Break down maintenance: Break down maintenance is done instantly when problem arises in
machine. In this case, repairs are made after the equipment is out of order and it cannot
perform its normal functions.
2. Routine maintenance: After a particular period of operation, the machines are cleaned &
reordered, that is routine or schedule maintenance. The maintenance department does it once
in a month. Schedule maintenance varies, time in time & also depends on situation according to
types of machines, because maintenance is directly related to products
Most of the time, all the screws, nuts, bolts & levers are checked, lubrication is also done. Workers
inform about the problem areas of the machines. Depending on their information maintenance is done.
Maintenance engineer analyze the records and take.
Routine:
Maintenance is a necessary task in any industry. But the degree and interval of maintenance is
dependent upon the age of the machineries. Landmark Textile Mills Ltd.has relatively new
machineries, which are very modern and state-of-the-art. Due to this reason a relatively less amount of

maintenance is needed to be carried out in Landmark Textile Mills Ltd. Never-the-less, routine
maintenance of the machineries of the dyeing section is carried out once a week. As the dyeing
section remains closed in Friday, the routine maintenance is carried out in Friday. As for break down
maintenance (very few break down cases occur), proper steps are taken to rectify the problem.

Compressed Air-
The requirement of compressed air is fulfilled by air compressor m/c. In
this m/c, natural gas is drawn by pipe through the filter above the compressor & the air is compressed.
In such a case the air becomes slightly hot. Hence cold water is drawn to reduce the temperature of
compressed air. While doing so, the cold water becomes slightly hot & it is transferred through outlet
pipe to the overhead reservoir. There the vapors are condensed and outlets drop by drop. Then the
water is let to fall slowly through the reservoir to the compressed air to obtain moist compressed
air.The moist compressed air is transferred to the dryer & a slight warm compressed air is delivered
trequired sections of Landmark Textile Mills.

ACRYLIC YARN DYEING

57 | P a g e
Introduction:
Now-a-days yarn dyeing is being very much popular as a means ofproducing raw material for woven
and knitted stripe fabric and sweaters. Landmarkgroup has developed a project for Acrylic Yarn
Dyeing to produce raw materials forsweater production in the year 2001. It’s a large project with
m/ccapacity of 1600 kgsand production per year is about 1400 tons. Here the Acrylic yarn is dyed in
hank dyeingsystem using cabinet type m/c.

6 Packing M/c
Brand : Power Pack
Origin :
Machine No. : 01
Capacity :
Operating : Pneumatic Pressure Operated
Features of Dyeing Machines:
Dyeing is done by overflow method
.Yarn hank is kept on stick inside the cabinet.
Temperature can’t exceed 98C i.e. atmospheric pressure m/c.
Sampling device remains at every m/c where sample is separately joined befor
dyeing commences. So it is possible to check shed without stopping the machi
Liquor circulation is done flowing three times up and three times down.
All the machines have own control unit, which can be programmer according necessity
Manual dozing system i.e. dozing is not computer controlled.
Features of Acrylic Yarn Dyeing Process:
Bulking is necessary to assure better penetration of dye.
Basic dye (here Tai–acrylic dye) is use for acrylic yarn.
Dyeing is done in acidic condition (pH 4-5).
Retarder and leveling agent is used to maintain dyeing accuracy.
In this process retarder calculation is very important.
There is a constrain in selecting dye%. It depends on the retarder calculation
.Softener and washing chemical is used if required at the end of the dyeing process
.As dyeing is done above the Tg of Acrylic yarn, temperature gradient must be
maintained carefully. Special dyeing curve is followed very carefully with specifi temperature
gradient.
High migration is another special feature of this dyeing.
M:L is maintained at 1:25.

Process Description:
Batching
Application of steam for 15 minutes to make the Acrylic yarn (hankform) fluffy. This aids penetration
of the dye molecules.
Dyeing :
Chief ingredients in the recipe–
1. Basic Dye
2. Acetic Acid–To maintain pH of 4–5.5. Usually 0.7 gm/liter is used.
3. PAN–Retarder (Not used for deep shade as color may bleed e.g. black)
4. AN–Leveling agent. Usually 0.6% is used.
5. Taisoft SSK–Cationic Softener (Requires acidic medium). Usually 0.5%


Dye Percentage Constraint
–There is a constraint in selecting dye percentage. For example say a sample is
dyed with 0.04% Tai Red GTL, 0.0135% Tai Red 6BNT and 0.047% Tai
BlueRGN.Theyestuffsfvalue of 0.58, 0.75, 0.33 respectively. Say, the
amountofretar.8anthesaturativalueofretarderderusedis1is 0.6.Now,
(Amount of particular dyef value) + (Retarder amountSaturation value of retarder)= (0.040.58 +
0.01350.75 + 0.0470.33) + (1.80.6)
= 1.46
The calculated value is less than 1.8 which is the saturation value of acrylic fibre. If this value exceeds
the saturation value of fibre, then the recipe is incorrect.
Hydro Extraction : For Acrylic yarn one passage is given.
Drying : Drying is done at 80c-100c.
Topping : PAN is not used. Only 50% amount of AN is used with
required dye addition.
Stripping : The dyed Acrylic yarn can be stripped with treating the
material with NaClO3andoxalic acid at 98c for 15 minutes. Then the material is washed for 10
minutes.
Quality Standard:
Landmark Yarn Dyeing Ltd. follows ISO:9001 2000 standardization for quality product
manufacturing.

CHAPTER–XIII
CONCLUSION

61 | P a g e
Landmark Textile Mills Ltd. is a well-planned versatile project. The administrations, management,
chain of command– all are well organized. They are devoted to satisfy the customer with their
activities.
Landmark Textile Mills Ltd. has following excellent features, which are worth mentioning in this
conclusion. These are,
The dyeing process of Landmark Textile Mills Ltd. is very quick and accurate. It is amazing that
with only 3.5 ton machine capacity Landmark is capable of 10 ton production daily. Furthermore very
limited amount of re-dyeing is carried out in Landmark, which proves the excellence of the dye-
house.
Landmark Textile Mills Ltd. has a very good labor management policy, which enables the smooth
running of the production line.
The Dye-house is very clean with excellent working atmosphere due to plenty of air circulation
and planned layout.
Landmark Textile Mills Ltd. has following drawbacks,
There is no water treatment plan in Landmark Textile Mills Ltd. The water obtained from the
pump is directly flowed to the dyeing machine without any treatment.
Due to shortage of textile engineers, night shifts some time continue production without any
production officer. As a result in some cases quality level drops.
College of Textile Technology has given us the chance to perform the industry a attachment in
Landmark Textile Mills Ltd. This attachment, acts as a bridge to minimize the gap between theoretical
and practical knowledge. Undoubtedly, this attachment taught us more about textile technology,
industrial management and production process. Besides it gave us the first opportunity to work in an
industry. I believe that, the experience of this industrial attachment will help us in our future career as
textile technologist.
