TEXTILE INTERNSHIP REPORT

Arvind Limited started with a share capital of Rs 2,525,000 ($55,000) in the
year 1931. With the aim of manufacturing the high-end superfine fabrics Arvind
invested in very sophisticated technology. With 52,560 ring spindles, 2552
doubling spindles and 1122 looms it was one of the few companies in those days
to start along with spinning and weaving facilities in addition to full-fledged
facilities for dyeing, bleaching, finishing and mercerizing. The sales in the year
1934, three years after establishment were Rs 45.76 lakh and profits were Rs 2.82
lakh. Steadily producing high quality fabrics, year after year, Arvind took its place
amongst the foremost textile units in the country.
Iミ the マid ヱΓΒヰげs the te┝tile iミdustヴ┞ faIed aミotheヴ マajoヴ Iヴisis. With the
power loom churning out vast quantities of inexpensive fabric, many large
composite mills lost their markets, and were on the verge of closure. Yet that
period saw Arvind at its highest level of profitability. There could be no better
time, concluded the Management, for a rethink on strategy. The Arvind
management coined a new word for it new strategy – Reno vision. It simply
meant a new way of looking at issues, of seeing more than the obvious and that
became the corporate philosophy.
The national focus pa┗ed ┘a┞ foヴ iミteヴミatioミal foIus aミd Aヴ┗iミdげs マaヴkets
shifted from domestic to global, a market that expected and accepted only quality
goods. An in-depth analysis of the world textile market proved an eye opener.
People the world over were shifting from synthetic to natural fabrics. Cottons
were the largest growing segments. But where conventional wisdom pointed to
popular priced segments, Reno vision pointed to high quality premium niches.

Thus in 1987-88 Arvind entered the export market for two sections -Denim for
leisure & fashion wear and high quality fabric for cotton shirting and trousers. By
1991 Arvind reached 1600 million meters of Denim per year and it was the third
largest producer of Denim in the world.
In 1997 Arvind set up a state-of-the-art shirting, gabardine and knits facility,
the laヴgest of its kiミd iミ Iミdia, at “aミtej. With Aヴ┗iミdげs IoミIeヴミ foヴ eミ┗iヴoミマeミt a
most modern effluent treatment facility with zero effluent discharge capability
was also established.
Year 2005 was a watershed year for textiles. With the muliti-fiber
agreement getting phased out and the disbanding of quotas, international textile
trade was poised for a quantum leap. In the domestic market too, the
rationalizing of the cenvat chain and the growth of the organized retail industry
was likely to make textiles and apparel see an explosive growth.
Arvind has carved out an aggressive strategy to verticalize its current
operations by setting up worldscale garmenting facilities and offering a one-stop
shop service, by offering garment packages to its international and domestic
customers. With Lee, Wrangler, Arrow and Tommy Hilfiger and its own domestic
brands of Flying Machine, Newport, Excalibur and Ruf & Tuf, Arvind set its vision
of becoming the largest apparel brands company in India.

Carding is the process of removing impurities from fibers and producing a carded
sliver of parallelized and straightened fibers
Before the raw stock can be made into yarn, the remaining impurities must
be removed, the fibers must be disentangles, and they must be
straightened.
The straightening process puts the fibers into somewhat parallel CARDING.
The work is done by carding machine.
The lap is passed through a beater section and drawn on rapidly revolving
cylinder covered with very fine hooks or wire brushes slowly moves
concentrically above this cylinder
As the cylinder rotates, the cotton is pulled by the cylinder through the
small gap under the brushes; the teasing action removes the remaining
trashes, disentangles the fibers , and arranges them in a relatively parallel
manner in form of a thin web.
This web is drawn through a funnel shaped device that molds it into a
round rope like mass called card sliver.
Card sliver produces carded yarns or carded cottons that are serviceable to
produce denim fabrics.
After carding, the carded slivers go to the draw frame.

Drawing is the process where the fibers are blended, straightened and the
number of fibers in the sliver increased in order to achieve the desired linear
density in the spinning process. The drawing process also improves the uniformity
or evenness of the sliver. The number of drawing passages utilised depends on
the spinning system used and the end products

Open end spinning:
Rotor Spinning is a more recent method of yarn formation compared
to Ring Spinning.
This is a form of open-end spinning where twist is introduced into the
yarn without the need for package rotation. Allowing higher twisting
speeds with a relatively low power cost.
In rotor spinning a continuous supply of fibers is delivered from
delivery rollers off a drafting system or from an opening unit.
The fibers are sucked down a delivery tube and deposited in the
groove of the rotor as a continuous ring of fiber. The fiber layer is
stripped off the rotor groove and the resultant yarn wound onto a
package.
The twist in the yarn being determined by the ratio of the rotational
speed of the rotor and the linear speed of the yarn.
Sliver is fed into the machine and combed and individualized by the
opening roller.
TEXTILE INTERNSHIP REPORT
Page
44
The fibers are then deposited into the rotor where air current and
centrifugal force deposits them along the groove of the rotor where
they are evenly distributed.
The fibers are twisted together by the spinning action of the rotor,
and the yarn is continuously drawn from the center of the rotor. The
resultant yarn is cleared of any defects and wound onto packages.
The production rates of rotor spinning is 6-8 times higher than that of
ring spinning and as the machines are fed directly by sliver and yarn
is wound onto packages ready for use in fabric formation the yarn is
a lot cheaper to produce.
Rotor spun yarns are more even, somewhat weaker and have a
harsher feel than ring spun yarns.
Rotor spun yarns are mainly produced in the medium count (30 Ne,
20 tex) to coarse count (10 Ne, 60 tex) range.
The yarn is wound on a big package of about 4 kg.
The use of this system has two basic advantages. It is fed by sliver,
not as with the ring frame by roving, and so eliminates the speed
frame from the process line. It can also be modified to remove any
remaining trash, thereby improving the yarn quality.

Warp Dyeing-
Normally the process of dyeing dictates the technology of Denim manufacturing.
The dyeing for Denim Fabric happens at the yarn stage. Generally there are two
most popular methods of dyeing Denim followed. They are:
1. Rope Dyeing
2. Slasher/Sheet Dyeing
Process flow of each of the above mentioned processes are discussed in detail
below.
Warping is transferring many yarns from creel of single-end package forming
parallel sheet of yarn wound on to be a beam or section beam. Warping
machines can process all type of materials including coarse and fine filament and
staple yarns, monofilament, textured and smooth yarns, silk and other synthetic
yarn such as glass.
A warp beam that is installed on weaving machine is known as weaver beam. A
weaver beam contain thousand of ends, but in denim production a beam obtain
from warping is known as section beam because denim is made from dyed yarn

1. ROPE DYEING
Believed to be the best possible indigo dyeing method for yarn, the threads
of denim yarn are initially twisted into a rope, and then undergo a
repetitive sequence of dipping and oxidization. The more frequent the
dipping and oxidizing, the stronger the indigo shade.
1 rope = 350-460 ends
Process Flowchart-
1) Ball Warping- the process of winding warp in rope form onto
balls.
Balls are cross wound packages and warp is form of rope.
Technical Details as per the company-

In this method a warp beams first converts into rope beamers and then transfer
to the Rope Dyeing machine for the further process.
Rope-dye ranges enable to produce pure indigo, sulfur bottom, sulfur top, and
colored denim yarn. The yarn goes through scour/sulfur dye, wash boxes, indigo
dye vats, over a skying device (to allow oxidation to occur), through additional
wash boxes, over drying cans and then is coiled into tubs which are transferred to
the Re- Beaming process.

2. SLASHER DYEING
In continuous slasher / sheet dyeing and sizing machine, direct warping
beams are used, instead of ball warping logs in case of Indigo rope dyeing
system. At the back end of the slasher / sheet dyeing range, the direct
warping beams are creeled. The yarns sheet from each beam is pulled over
and combined with the yarns from the other beams so that multiple sheets
of yarns can be made.
In sheet dyeing range, the total No of required ends for a weavers beam are
dyed, dried, sized and dried simultaneously. This continuous slasher dyeing
range eliminates a few intermediate processes of the rope dyeing, such as
re-beaming, sizing.

Finishing and Processing
Arvind Mill, Naroda boasts of 2 integrated finishing ranges and 2 other finishing
departments. In integrated denim finishing range, the singeing and shrinking is
carried out in a single range. This reduces the process time, material handling,
cost of production and labour cost.
Finishing of grey denim fabric normally carried out after weaving. It takes an
important role infabric properties, appearance, softness and residual fabric
shrinkage.
The department churns out 300000 meters of finished denim cloth a day.
The main purposes of applying various finishes may be summarised as under.
1. HIGH SALES APPEAL: To impart properties of attractive appearance, supple
handle, softness and good drape.
2. HIGH WEAR QUALITY: This refers to adequate tensile and abrasion strengths,
dimensional stability, crease recovery and freedom from pilling.
3. BODY PROTECTION AND COMFORT: This relates to proper heat insulation,
moisture absorption and air permeability.
4. SPECIAL EFFECTS: These include water-repellency, reduced flammability,
mildew and moth-proofing, anti-static behaviour and soil release property.

DID is a critical unit for the innovation and creativity that Arvind mills projects.
The department has been constituted in such a manner that it has 2 parts-
The Design Team
The Technical Team
Design Team:
The design team has a constant responsibility of re-innovating denims.
It consists of fashion consultants from Europe and other countries along
with the textile experts and textile designers.
The team works together to create a completely different denim design.
Though it seems like innovation in design in denims has limited scope,
this group of professionals use their creativity and constant thinking
skills to come up with unprecedented designs.
They follow trends, customer feedback and various trends in the various
parts of the world, research it and come up with innovative ideas.
These new designs are featured in fashion shows across the globe, for
top fashion experts to see and review, and hence maintain the
exclusiveness of denim produced by Arvind Mills.
Top designers like Calvin Klien, Chanel etc. and brands like Zara,
Abercrombie and Fitch, Mango, Gap and many others, select these
designs and order them to be produced in mass.
The designs can be created by changing one of the following
characteristics of the fabric:
Denim Incubation Department | Design Team
TEXTILE INTERNSHIP REPORT
Page
67
Weave of the fabric:
o (denim is usually 3 x 1 twill)- variations are made in twill weave
or by changing the nature of the weave all together. Like 2X1
or other variations
The d┞iミg proIedure’s output:
o (usually done with indigo and sulphur dyes) – the dying can
give colour effects to the fabric. Different compositions of
dyes are used and innovations and creativity in the use of
colors, produces more number of designs. Sometimes the
weft and the warp are of different dyes, creating an
iridescent effect. Though traditionally blue or black, many
other colours of denims are created
Fiber Used:
o Authentic denim uses cotton fiber, but for design variations
cotton blends are used. Light weight yarns like polyester are
used to manufacture denim used in garments like jeggings
and lighter weight denim requirements. Most popular
addition to denim fabric is Lycra for streatchability as that is
a prominent feature of jeans. Most recent type of denim
added to the denim family of Arvind is E┝Iel deミiマ(┘orld’s
softest denim)*.
TEXTILE INTERNSHIP REPORT
Page
68
Finishes Applied:
o Fabrics can be re-innovated in terms of the type of finish
applied, Now-a-days, there are a variety of finishes that can
be applied to any fabric and same goes for denim. Usually
mercerization is a process not done for denims, as it does
not require very soft and smooth fibers, but inclusion of
finished like mercerization or resin finish, can completely
change the look and feel of the fabric. Other aesthetic
finishes, like partial napping or emerization, anti-crease
finish, permanent creases by resin finish can be given.

The following are a few lines of denim that have been developed and new
products are added to it every day:
Kato (Japanese denim line):
o Kato brings in the authentic attributes of denim in collections, fabrics
mostly made on the shuttle loom and with selvedge.
ADL (Arvind Denim Lab):
o The ADL line is specifically for the US brands. The s/s 2014 collection
has special attractions in the form of colour denims, indigos with
colour fills andsummer lights in excel along with the authentic core
line
Euroline (European denim line):
o The Euroline is specifically for the brand needs inEurope. The s/s
2014 collection has an introduction of shades like pink, sky blue but
in a grading of color.
Metro (Indian denim line):
o The マetヴo liミe is desigミed H┞ Aヴ┗iミdげs iミ-house design team
specifically for Indian brands. The collection has the flavor of a true
Indian denim. We have also recently launched a collection in Excel
called Excel Denim in collaboration with Birla Cellulose. It will be the

The technical team of the development and new technology team aims
at developing the fabric as per customer requirements.
They have technicians and fabric experts who constantly work together
and collaborate with each of the processing units to get the desired
output of the fabric.
Then, they calculate/concur and document the exact procedures and
processes to be followed to create the fabric exactly matching customer
requirements.
Once the processes have been determined by the DNTG department,
they are delegated to the individual units for mass production.
The DID DEPARTMENT at Arvind mills has a database of more than
8000 fabrics, that have been created for all kinds of uses. The designs
range from all kinds of usage of yarn, to differentiation based on any of
the factors mentioned above.
Customers and designers may choose out of this data base to order in
bulk, The data then goes to PPC department, that is production Planning
and Control and the mass production of fabrics start.
Collection development is done at least one year in advance and
presented on a road show/ramp show for the buyers to see and order.
These shows contain 30-35 pieces each o the type of fabric
characteristic being showcased.

Arvind is committed at providing the best quality of fabric to the consumers for
over 80 years now. The quality control is an integrated process that starts when
the customer gives the order, and the DNTG develops the samples accordingly, it
is checked for quality assurance measures and compliances with customer needs.
At later stages the fabric is inspected and testing of parameters of fabric is done.
Essentially there are 2 major parts of quality assurance:
QUALITY ASSURANCE AND STANDARDISATION
Inspection department uses 13 Kitamura Machine to find such defects
in fabrics.
The inspection frame is aligned at an angle between 45 and 60
degrees.
Speed of fabric on inspection m/c : 25m/min
Light : 100 Lux
Inclination : 570
Cost of inspection : Rs. 0.65/mtr

Arvind follows 100 percent inspection procedures. The acceptance level of the
fabric depends on the customer preferences.
There are two inspectors to keep continuous watch on fabric for finding the
defects. The 4-point grading system indicates that as per customer requirement
defects are allowable upto their levels. We have observed that in VF brand the 4-
point allowable are only 4 that is total 16 defects per 135-meter roll.
4-point grading system is used for inspection of fabrics and this includes:
Size of defect Penalty Points

Major Defects are classified as follows:-
Major woven fabric defects such as slubs, holes, missing yarn, conspicuous
yarn variation, end out, soiled yarn, and wrong yarn.
Major knitted fabric defects are mixed yarn, yarn variation, runner, needle
line, barre, slub,hole, press off.
Major dyeing or printing defects are print out, dye spots, machine stop,
color smear or shading.
Fabric containing more than 40 points per 100 square yards is considered as
SECONDS .
At the beginning of the month the inspection department gets the production
plan for the entire month and they plan their procedures accordingly. The
finishing department gives the material transfer note to the inspection
department where the material is checked for the following defects:

The bowing and skewing are calculated as follows:
Bow: A bow is an uneven deviation of a weft from a line drawn perpendicular to
the selvedge of the fabric.
A bow may have different forms:
If the average Bowing or Skewing for a roll is more than 2-3%, reject the roll.

Shade testing:
The software used for shade testing is EASY MATCH.
HunterLab's EasyMatch QC software gives unprecedented flexibility to
process, display, analyze and report color measurement results.
Color measurement and analysis software reports absolute and color
difference data in all widely used color scales, for various lighting and
observing conditions. Pass/Fail functions provide fast go/no-go decisions.
Data can be reported numerically in tabular or spreadsheet form.
Data can also be graphically displayed as color difference plots, trend plots
and spectral curves.
All results can be viewed, stored, printed or imported into your database
programs.
The software uses a spectrophotometer to record observations, and plots
deviations from avg and perfect sample for each roll.
It also provides pass and fail options for rolls that deviate too much from
normal value making it very easy for the operator to assure quality and
minimize shade variation.
It also helps in shade wise differentiation and categorization of rolls. So that
the consumer may be able to easily distinguish between lots of various
shades

INTRODUCTION
The Better Cotton Initiative (BCI) is primarily focusing on the following :
To demonstrate the inherent benefits of BC production, particularly the
financial profitability for farmers.
To reduce the impact of water and pesticide use on human and
environmental health.
To improve soil health and biodiversity.
To promote Decent Work for farming communities and cotton farm
workers.
To facilitate global knowledge exchange on more sustainable cotton
production.
To increase the traceability along the cotton supply chain.
Better Cotton Initiative | Introduction
TEXTILE INTERNSHIP REPORT
Page

KEY FEATURES
Producers need to meet the Minimum
Production Criteria which are the initial core
requirements, to receive a license to produce
BC.
Minimum Production Criteria (MPC) are the
starting point in a cycle of continuous
improvement required by BCI. Once MPC are
met, producers have to address Progress
Requirements.
BCI aims to transform cotton production
worldwide by developing BC as a sustainable
mainstream commodity. There is not BC label
on final products.
A major partner speeding up the production
of BC is the BC Fast Track Program. Leading
BCI brands as well as a number of public
sector funders contribute to the BC Fast Track
program, which channels funds directly to
farmer training and improvement programs,
all designed around the BC standard. This
allows BCI and its partners to reach more
regions, train more farmers and produce
more cotton.
BCI membership focuses on enabling positive
change in the field, supporting supply
creation, building public support and
demonstrating market place demand for BC as
a mainstream commodity.

The Better Cotton System
The Production Principles and Criteria cannot operate in isolation, and form part
of the BC System. This BC System is made up of the following inter-dependent
components, each as important as the other in making the system effectively
deliver its objectives:
• Production Principles and Criteria to provide a global definition of BC
• Farmer Support to promote enabling mechanisms at a local and global level,
working with experienced implementing partners, and stimulating public-private
partnership funds to implement these mechanisms
• Farm Assessment to encourage farmers to continuously improve, through
measuring results and seasonal learning cycles
• Supply Chain connecting supply with demand through an identifiable bale of
100% BC lint
• Monitoring, Evaluation and Learning mechanisms to measure progress and
change and to ensure the BC System has the intended impacts on its direct
beneficiaries
• Tools, guidelines and learning forums to facilitate the exchange of best practices
and knowledge to encourage the scaling up of collective action

PRODUCTION PRINCIPLES
BC is produced by farmers who minimize the harmful impact of crop
protection practices
BC is produced by farmers who use water efficiently and care for the
availability of water
BC is produced by farmers who care for the health of the soil
BC is produced by farmers who conserve natural habitats
BC is produced by farmers who care for and preserve the quality of the
fiber
BC is produced by farmers who promote decent work
CRITERIA FOR ASSESSMENT
Pass and fail:
Producer need to respect Better Cotton Minimum Production Criteria in
order to get a license to produce BC. The BC system aims at continuous
improvement. It is not organized as a simple pass or fail system but goes
beyond by integrating elements of capacity building, data management,
and progress.
What happens if non-conformity is found?
At least 80% of the farmers in Learning Group must comply with all relevant
BC criteria in order for the group to get a license to produce BC. Where a
systematic breach of a Minimum Production Criteria is observed, the whole
Producer Unit may be disqualified.

AUDIT INFORMATION
1st, 2nd, 3rd party certification:
The BC assurance system is a combination of self-assessment, second party
credibility checks and third party verification.
Frequency of audits: Yearly
Validity of audit certificate: One year.
PRODUCTS TRACEABLITY ALONG THE SUPPLY CHAIN
One of the key elements of the supply chain for BC is the creation of 100% BC
bales, meaning that BC is segregated from farm to gin.
Chain of Custody standard
BCI will create a 100% BC bale, and connect the supply of BC to demand,
putting in place a supply chain system that facilitates the procurement of
BC.

SUPPORT
To help farmers adopt practices consistent with the BCI Production Principles, BCI
coordinates a program of farmer support activities delivered through experienced
Implementing Partners.
Farmers support covers knowledge sharing and skills development and effective
producer organization For Implementing Partners, three of the BC System
components focus on support. BCI provides a Step by Step Guide to
Implementation for both smallholders and large farms and annual workshops that
help companies understand and implement the BCI program. Applications for
financial grants can be submitted twice a year through an online form. The
funding contribution matches up to a maximum of 50% of the total project cost.
Members receive supply chain support from dedicated supply chain coordinators,
as well as Secretariat and Council support through Caucus calls, BCI hosted events
and webinars.
COSTS
Membership fee: The membership fee is based on member category, size
and either annual lint cotton consumption, annual turnover/income, or
whether the organization is based in an OECD Country or a non-OECD
country.
Certification costs: Third party verification costs are born by large farms or
by BCI in the case of smallholders.

Economic benefits
Reduced cost of production: The cost of production is reduced through the
collective purchase of farm inputs and better, economical deals from
suppliers.
Better profitability: The need for middle men has been eliminated as
Arvind ensures that the produce is bought at the farmer's door step.
Better access to affordable finance: Dependence on local moneylenders
has also been reduced as farmers are encouraged to deal with reliable
financial institutions.
Better nutrient, pest and disease management: Better management
practices ensure reduced use of inputs (like synthetic pesticides & fertilizers
), untimely reducing the risk taken in synthetic pesticides handling and
application.
Knowledge sharing and skill development: Farmers receive practical
knowledge on production principles that can decrease the cost of
production and increase profitability.
Quality of fibre: From soil preparation to harvesting and segregating better
quality cotton at the farm gate, our agronomist are involved in every
process to ensure better quality cotton.

As the leader of Indian textile industry, Arvind has taken it upon itself to
develop models that make production of its most valued and most extensively
used raw material i.e. Cotton more sustainable.
Application of BCI Norms by Arvind has not only uplifted the lifestyle of the
workers under the BCI project but has also enhanced the overall quality level of
Cotton yarns since its quality is based on the uniformity level of Cotton fibers.
The BCI Cotton has a much lower Coefficient of Variance despite being
manufactured in different areas than the normally procured cotton from the
same areas.
The uniformity index of BCI-BB is 88.8 as compared to the uniformity index
of BB i.e. 81.6 which is significantly lower than the BCI-Cotton and affects its
quality greatly.
