DYE HOUSE PROJECT
Company & Process……………
Established in 1994, Ocean Lanka is the largest manufacturer of Weft Knitted Fabrics in the
island located in Biyagama Export processing Zone and jointly owned by Fountain Set (Hong
Kong), Brandix and Hirdaramani with over 1800 employees. A well-established, respected and
fast moving company manufacturing and supplying weft knit fabrics (Single Knits, Double
Knits, Flat Knit, Prints & Yarn Dyed) to the Sri Lankan apparel industry for a growing number
of international brands, including Victoria’s Secret, Next, Marks and Spencer and Nike.
Ocean Lanka possesses the total Textile manufacturing process and facility except for Yarn
making. This includes Yarn, greige (Raw cloth) & finished fabric ware houses which can
accommodate more than production & output demand. The process mainly comprised of
Yarn processing, Yarn dyeing, Piece (raw cloth) Dyeing, Fabric treatment & finishing, Fabric
Printing and Quality Control. There are few other sub processes which support the main
process units. Generally Ocean lanka makes approximately 2,000,000 lbs. of finished fabrics
per month (there could be higher or lower values depending on the Brand and season
demands).

Problem & Cause……………………..............
In general, a Project is defined as a collaborative enterprise, involving research or design that
is intentionally planned to achieve a particular Goal or a solution to a prevailing problem. But
it is rather temporary than permanent social systems or work systems that are constituted
by teams within or across organizations to accomplish particular tasks under time
constraints. Or in simple terms a temporary specified task with scope, time, cost and quality
limitations. In that context, the Project in this Episode was designed to provide a reliable
solution the said production capacity problem which has hampered the Dyeing Department
performance for a long time. Hence this episode will be segmented to present a clear view
relate to the cause, remedy, design, works and the final result.
In order to achieve the expected finished fabric quantity, there are certain Dye production
quantity have to be met. This depends on the machine output/cycle /Day. Further, there are
more than 3,000 Fabric types Ocean lanka has developed and has the capacity to manufacture
–this is an on-going process and new fabrications (total fabric making process) are being
added continuously. This has added more dye batches where existing number of Dye
machines cannot handle in given time. All these incidents has created an unwanted delay time
in Dye process due to elongated Queue time in Dye machines. There are 68 Dye Machines
with only 10 machines which have high temperature recipe.
This problem has created 17-14 days queue in most of the smaller capacity machines ranging
from 30 lbs to 250lbs. The analysis has shown that this trend has created by the Brand
Demand; created by the consumer Demand & trend; which has reduced more Bulky Dye
orders and demand was focused on smaller Quantities. –Refer Table 1

In order to find the cause for this, machine queue data from 2012 & ongoing (2013) were
compiled. The purpose of this exercise was to come up with the right combination of machine
capacities.

This analysis was the prime evidence to raise a case against Production delays and On-Time-
Delivery issues. Hence it was decided to replace existing machines with high temperature,
low-liquor ratio machines which will consume less Electricity, Steam , Chemicals (Dye stuff)
etc..
Assumptions & Aims………………………
--- The Obvious primary aim of this project is to reduce the prevailing machine delays, which
has caused the company in terms of On-Time-Delivery rating, defects appeared after Dyeing
due to greige fabric in idle for longer periods, low production.
----The second aim of the project is to reduce the water usage as Textile Dye process is one of
the most water consuming production process anywhere in the world. Although there are
other inventions like Air Flow machines (a Forced draft is used to create the turbulence inside
the machine to support the dye absorbing process) and most advanced models like
“Waterless Dye machines” (Already one of the most sought after Brand has started an
Experimental Factory process in Asian region) . In the Textile Dye terminology, the water
contribution is known as Liquor ratio (L/R); the ratio between Dry weight of the Fabric and
the water requirement for dyeing process (Although there are more sub processes connected
to the total Dye process like Scouring, Washing –as many washing cycles as the particular
fabrication specified, Rinsing etc. which may need different water quantities, the Liquor ratio
is referred to the water quantity required for the total process as an average). In the Ocean
Lanka case, the average L/R was between 8:1 to 9:1. The magnitude of this number will be
visible when we consider an average monthly Dye production of 2,000,000 lbs. (this may vary
between 2 million – 2.5 million)
Hence monthly average Dye production – 2,000,000 lbs (909,090 Kgs)
Water consumption @ Dyeing 8:1 Liquor ratio + - 7,272,720 ltr
(But total water consumption was averagely 50ltr/ lbs of finished fabric)
The Specifications of the Machine Model selected for the Project mentions the factory tested
L/R as 4:1 but we assume the practical value to be between 5:1- 6:1 due to waste between
sub processes, drain efficiencies etc... Hence this was one of the Intended targets of this
Project. As per the manufacturer’s specifications, they will achieve this through the inside
structure- the change in the fabric path inside the Dye chamber, the high temperature option
will reduce the water quantity needed to dissolve the specified dye quantity and the final

absorption will be faster, Change in the Dye Process Recipe will reduce the time taken for the
process through improved methodology, Change in the Dye Cycle
---- The third aim is to regularise the working temperature of Dye machines. Cotton fabrics
needs lower Temperature surrounding whereas Lycra based or Polyester needs high
temperature dye solution to achieve high efficiency. With existing machines, the Production
Planning & Control Department have to choose Dye batches & swap them across varying
Machine capacities and varying Temperature classes.
----The High Temperature option will give the total Dye cycle time to be shorter than the
current process as the Dye solution will reach the desired temperature faster. This is the most
important goal in this venture as it will give the Machine Cycles per Day from 1.6 (current
value) to a minimum of 2 or could be more (the target would be to reach 2.5)-Refer the
projected values.

Project progress…………………
Floor (Foundation)
The existing floor is craggy and damaged. It was decided to Re-concrete the Floor to have an
even surface in order to support smooth mounting of machines
Hence to have a sufficient mass and stiffness to permit the machine to operate in or near a
state of equilibrium we’ve decided to lay Grade 30 concrete since lack of mass and stiffness
causes normal operating forces to generate abnormal vibration levels that reduce useful life .
GRADE 30 Concrete Delivery specification

To lay the new foundation, Old machine Plinths were removed and the floor was prepared
with dowel pins (6” x6”). Although the new Concrete layer was laid, 14 out of 34 new
machines will be mounted on plinths in order to make the working level (machine operator’s
hip level). Hence individual concrete plinths were formed with the floor re-concreting.
Anchoring
Anchor bolts were used to secure the machine to its foundation. Marking for machine
placement was started soon after the 14 day concrete curing period. J-bolts were fixed into
the concrete as it is poured. Size bolts to ensure adequate holding torque and to prevent
them from loosening over time. Exercise care when selecting the grade of bolt, and
determine if the mounting pattern will be rigid enough to lock mounting plates to the
foundation.
Leveling
Before the machine was placed in line with anchor bolts, leveling of the allocated area was
finally checked. It was found that with few exceptions, machinery is designed to operate on a
true horizontal plane. When taking the old plinth level (highest level) & the craggy floor level
(lowest level) the difference was 156mm. To have an economical concrete solution, old
plinths were demolished but even then in actual concrete pouring period some areas were
filled to 200mm whereas the lowest was 72mm.
Initially a Survey telescope was used to level the new concrete floor. The results were within
the tolerance limit, it was not necessary to level each allocated area but a liquid level was
used to level each machine properly. Shims with different thicknesses were used to provide
full footprint support giving a rigid connection between the mounting feet and the
foundation.
Alignment

As for the total alignment of all parts of the machine, final requirement is proper alignment of
the machine's Main vessel, Plaiting Device, Salt Tank, Service Tank, Preparation Tank and
Heat Exchanger. Total machine Leveling was done to ensures that the entire machine-train is
level to the earth.
In progress----
Moving new machine parts to
the designated location

For the Mintec3-1T-120kg machines, as per the description of 0.7 m height drainage, 0.8
height concrete base for dyeing machines and 1 m height working platforms, attached
please see the reference layout drawing. Regarding the 1 m working platform:
- Due to piping arrangement, service tank cannot be move closer to ground level. For
operator to input the chemical / dyestuff, would you consider to plan
some steps in the machines’ 0.8 m height concrete bases.
- When you prepare the 1 m height platform, please also prepare handle around the
platform to protect the workers.
- Please note that the fabric trolley cannot be move too close to the machine. However
for the 120kg which does not carry too much fabric, we don’t think it will create
problem.
Dismantling existing machines
while other machines are in
operation

The commissioning procedure of the high temperature Dye machines all share a common
procedure as,
Post Installation review……..
Ocean Lanka has reviewed the performance of replaced Dyeing machines after the first year
of operation (first 21 machines –other 12 machines were commissioned on 3rd
quarter 2014)
• Remove old technology, costly spare parts in different type of machines.
• Improved its technical features including more reliable measures. Instead of old
MIR/MSR function, introduced AIR+ function to automatically control the salt level
inside the machine.
• Can measure the energy consumption (Electricity) machine itself and can monitor
them well.
• Water fill controls through flow meter (Main process inlet), all the controls, and
programs operated to the accurate water flow meter readings. Improved the accuracy
of water consumption levels.
• Reduced the batch cycle time. Could improve the batches per day from 2 to 3. In some
ISO thermal programs it is 2 to 4 per day.
• The reduced liquor ratio-led to reduce the water, steam, power consumption and
enormous saving on the chemicals.
• Improved evenness in internal Dye concentration.
• Improved internal fabric movement by controlling plaiter and the lifter reel.
• Introduced new internal lint (fabric dust) collection pump which improve the quality of
the fabric, reduce loose lint.
• Improved ergonomics-worker operational easiness. They can work on the floor –
previously they have to work on platforms.
• Use of Preparation tanks saved the batch cycle time, heated exit water when cooling,
prepared chemicals.

• Remove old technology, costly spare parts in different type of machines.
• Improved its technical features including more reliable measures. Instead of old
MIR/MSR function, introduced AIR+ function to automatically control the salt level
inside the machine.
• Can measure the energy consumption (Electricity) machine itself and can monitor
them well.
• Water fill controls through flow meter (Main process inlet), all the controls, and
programs operated to the accurate water flow meter readings. Improved the accuracy
of water consumption levels.
• Reduced the batch cycle time. Could improve the batches per day from 2 to 3. In some
ISO thermal programs it is 2 to 4 per day.
• The reduced liquor ratio-led to reduce the water, steam, power consumption and
enormous saving on the chemicals.
• Improved evenness in internal Dye concentration.
• Improved internal fabric movement by controlling plaiter and the lifter reel.
• Introduced new internal lint (fabric dust) collection pump which improve the quality of
the fabric, reduce loose lint.
• Improved ergonomics-worker operational easiness. They can work on the floor –
previously they have to work on platforms.
• Use of Preparation tanks saved the batch cycle time, heated exit water when cooling,
prepared chemicals.

Machine capacity change in New & old Dyeing machines
Old Machine Capacity NewMachine Capacity

----The second aim of the project is to reduce the water usage as Textile Dye process is one of the
most water consuming production process anywhere in the world. Although there are other
inventions like Air Flow machines (a Forced draft is used to create the turbulence inside the machine
to support the dye absorbing process) and most advanced models like “Waterless Dye machines”
(Already one of the most sought after Brand has started an Experimental Factory process in Asian
region) . In the Textile Dye terminology, the water contribution is known as Liquor ratio (L/R); the
ratio between Dry weight of the Fabric and the water requirement for dyeing process (Although there
are more sub processes connected to the total Dye process like Scouring, Washing –as many washing
cycles as the particular fabrication specified, Rinsing etc. which may need different water quantities,
the Liquor ratio is referred to the water quantity required for the total process as an average). In the
Ocean Lanka case, the average L/R was between 8:1 to 9:1. The magnitude of this number will be
visible when we consider an average monthly Dye production of 2,000,000 lbs.
The Specifications of the Machine Model selected for the Project mentions the factory tested L/R as
4:1 but we assume the practical value to be between 5:1- 6:1 due to waste between sub processes,
drain efficiencies etc... Hence this was one of the Intended targets of this Project. As per the
manufacturer’s specifications, they will achieve this through the inside structure- the change in the
fabric path inside the Dye chamber, the high temperature option will reduce the water quantity
needed to dissolve the specified dye quantity and the final absorption will be faster, Change in the
Dye Process Recipe will reduce the time taken for the process through improved methodology,
Change in the Dye Cycle
---- The third aim is to regularise the working temperature of Dye machines. Cotton fabrics needs
lower Temperature surrounding whereas Lycra based or Polyester needs high temperature dye
solution to achieve high efficiency. With existing machines, the Production Planning & Control
Department have to choose Dye batches & swap them across varying Machine capacities and varying
Temperature classes.
----The High Temperature option will give the total Dye cycle time to be shorter than the current
process as the Dye solution will reach the desired temperature faster. This is the most important goal
in this venture as it will give the Machine Cycles per Day from 1.6 (current value) to a minimum of 2 or
could be more (the target would be to reach 2.5)-Refer the projected values.
