2. Preface
RMG (Ready Made Garment) is very important and helpful
for our Bangladesh. Bangladesh has emerged as a key
player in RMG (Ready Made Garment) sector since 1978.
I have completed this report on the basis of all the
department of RMG sector. So by completing this report I
get overall idea about RMG sector. I preferred this
attachment in Bengal Hurricane Group, which is a 100%
export oriented knit industry. For continuing the study of
internship in the Bengal Hurricane Group i almost worked
all the sections of this company and tried to find out the
activities, planning and many other things as well.

5. The plant is capable of producing knit
fabrics of different texture &
construction. So I learn about
Single Jersey.
Interlock.
Viscose.
Lycra.
Nylon.
Polyester
1X1 and 2X2 Rib Fabrics.
Pique Fabrics
Fleece.

6. Yarn count
Yarn count: The yarn count is a numerical expression which defines its fineness
or coarseness. It also expresses weather the yarn is thick or thin. A definition is
given by the textile institute – “Count is a number which indicates the mass per unit
length or the length per unit mass of yarn.”
Types of yarn count:
a) Indirect system- English, Metric, Worsted.
b) Direct system- Tex, Denier, Lbs/Spindle.
Indirect count: The count of yarn expresses the number of length units in one
weight unit. Thus higher the count, finer the yarn. The system is generally used
for cotton, worsted, linen (wet spun) etc.
Direct count: The count of yarn expresses the no. of weight units in one length
unit. Thus higher the count, coarser the yarn. The system is generally used for
synthetic fibre, jute, silk etc.

17. DESIGN SECTION
First Process Receive Artwork From Buyer Via
Merchandiser.
Then Start Work to Make Design from That Artwork.
After Finishing The Design Work Designer Print Out That
in Film Paper. But Some Time It Is Not Possible To Print
The Design From In House Facilities, Because Of Design
Size Or Various Kind Of Dot. That Is Why They out Put
This Kind Of Design from Other places.
After That Designs Are Ready For Sample Making.

20. Sampling department
Sequence of Sampling:
1ST Pattern → 2ND Pattern → Counter Sample → Salesman Sample
→ Photo Sample → Approval Sample (Size Set, Mock-Up) →Pre-
Production Sample → Production Sample → Shipping Sample.
Responsibilities of sampling department:
Getting clarifications about style details from merchandiser.
Checking pattern’s workability.
Preparation of different samples and getting the buyer’s approval.
Informing quality related problems, encountered during preparing
samples, to QC.
Minimizing operations and consumption.
20
21. Cutting department
Marker making:
Marker making is the process of determining the most efficient layout of
pattern pieces for a specified style, fabric, and distribution of sizes
(requires time, skill and concentration)
Factor of Marker making:
Marker making is a critical step in the manufacturing process.
By retaining strict control over this critical step, they keep the fabric
consumption as low as possible.
It also ensures that the issues that affect quality will be given proper
attention. These include placing patterns on grain, keeping patterns
paired, and attending to details such as drill holes and notches.
Depending on the relative efficiency of each marker produced, the
company may save or waste thousands of dollars a year.
21
22. Cutting M/C
Straight Knife
Vertical blade
Reciprocates up and down
Corners and curves can be cut accurately
Most versatile and commonly used
Blades length - 6 to 14 inches
Spread depth depends on blade length & adjustable
height of the blade guard
All of the pieces cut from a lay are identical
22
23. Stickering, Checking,
Sorting&Bundiling.
Stickering:
Sticker carry details : style no, size, ply no, bundle no., date issued
Operations may be incorporated for payment purposes, control of
work and facilitating quality control
Checking:
Here all the cutting parts have to check properly. Find out the faults
and take apart from here and cut same part of the garment in same
shade.
Sorting&Bundiling:
Small batches of garments move from one work station to another in
a controlled way
Tens, dozens, 2 dozens, etc.
23
24. Sewing
Production system:
1.Progressive bundle system-
Sewing operations are laid out in sequence.
Each operator receives a bundle, does his work, reties the bundle and passes it
to the next operator.
There is a storage facility such as rack, bin or table for storing the inter-process
work between each operation.
The work is routed by means of tickets.
2. Unit production system
A unit production system (UPS) is a computer-controlled production line.
It is a type of line layout that uses an overhead transport system to move
individual units from work-station to work station for assembly.
All the parts for a single garment are advanced through the production line
together by means of a hanging carrier that travels along an overhead conveyor.
Production operations are completed without removing the parts from the carrier.
24
25. Sewing
Seams:
The basic function of a seam is to hold pieces of fabric together.
To perform its function correctly, the seam should have properties
or characteristics closely allied to those of the fabrics being sewn.
The careful selection of the most appropriate seam, a suitable
stitch type together with the correct thread and machine settings
for the fabric and end-product is of paramount importance.
Classification of seams:
Superimposed seam
Lap seam
Bound seam
Flat seam
Edge finishing
25
26. Quality department
Inspection terms:
Sample: A sample consists of one or more units of a product drawn
from a lot or batch, the units of the sample being selected at
random without regards to their quality. The number of units of a
product in the sample is the sample size.
Lot or batch: Means ‘Inspection lot’ or ‘Inspection Batch’ that is a
collection of units of a product from which a sample is to be drawn
and inspected.
Lot or batch size: The lot or batch size is the number of units of a
product in a lot or batch.
Identification of defects:
Major Defect: A defect that, if conspicuous on the finished product,
would cause the item to be second.
Minor Defect: A defect that would not cause the product to be
termed as a second either because of severity or location.
Second: A ‘Second’ is a garment with a conspicuous defect that
affects the salability or serviceability of the item.
26
27. Finishing department
Operations performed at finishing stage:
Thread cutting: Uncut threads affect the presentation of finished and packed
garments. Therefore, it is necessary to cut and trim the loose and uncut threads.
Stain removal: Removal of the following type of stains:
Oil, yellow, black and paint spots, stains due to color bleeding, ink, rust, tracing
marks, yellow stains, and hard stains
Seam ironing: Ironing of garments using steam ironing tables with vacuum
boards.
Final finishing: The entire garment is finished using various finishing equipment’s.
Tagging and packing: The pass pieces are brought to the tagging and packing
section. It is the responsibility of the packing supervisors to provide the tagging
operators with the appropriate price and brand tags. He also instructs the
tagging operator as to where and how the tag has to be placed. The most
important thing to be kept in mind while placing the tag is to match the size
mentioned on the main label and the size on tag. The step after the tagging is to
pack the garments as per the specification of the buyer.
27
28. Finishing department
Presentation checking and cartoon packing
First Checkers check the packed garments for the following things:
Poly bags are as per specification.
Tags and price stickers are as per specification.
Packing is secured or not if specified.
Poly bags should not be soiled and torn.
Hangers are there or not if specified.
Garment has been folded as per specification etc.
Once, checking is done they send the garments for the carton packing. The following things
are kept in mind during carton packing:
Number of garments to be packed in one carton.
Ratio asked for example S:M:L=2:1:1
Packing the garments in the cartons as per specified.
Closing the cartons with cello tape.
Sealing the cartons with plastic cord.
Writing on carton information like: Store or buyer name, buyer's address, ratio, net
weight of the carton etc.

32. Conclusion
I can say that this internship report is really essential for
every student of Textile engineering to get idea about
textile industry. By completing this report I have got overall
idea of RMG sector and these may be helpful to know about
the technical and management knowledge of garments
industry also these sector related organizations. This is a
huge sector and yet to discover the whole.
This Internship program will help me in the further
challenges of life. I try my best to make this report
enriched with lots of apparel related documents.
