2 INFORMATION ABOUT FACTORY
2.1 INTRODUCTION
If the theoretical knowledge is a glass of water then the practical knowledge would
be drinking of the water. It is always very easy to make a man understand about a
firebox by showing and lighting practically rather than describing theoretically
who has not ever seen a firebox. So, for any technical education the practical

experience is the most important along with the theoretical knowledge. As we are
studying in a technical line, it is always important for us to gather the practical
knowledge. Through our study life the only biggest chance for us to combine the
theoretical knowledge with the practical knowledge is the ‘Industrial Attachment
period’ that comes only once in the education life.

3.1.1 KNITTING
The term knitting describes the technique of constructing textile structures by
forming a continuous length of yarn into columns of vertically intermeshed loops.
It relies heavily on the availability of fine, strong, uniformly spun yarn. The term
‘knitting’ dates from the mid-sixteenth century, earlier words such as the Saxon
‘cnyttan’ and the Sanskrit ‘nahyat’ being less precise, indicating that knitting,
probably evolved from sources such as the experience gained by knotting and
Coptic knitting.
Knitting Structure:
Knitted structures are progressively built-up from row after row of intermeshed
loops. The newlyfed
yarn is converted into a new loop in each needle hook. The needle then draws the
new loop
head first through the old (fabric) loop, which it has retained from the previous
knitting cycle. The needles, at the same time, release, (cast-off or knock-over) the
old loops so that they hang suspended by their heads from the feet of the new loops
whose heads are still held in the hooks of the needles.
A cohesive knitted loop structure is thus
produced by a combination of the intermeshed
needle loops and yarn that passes from needle
loop to needle loop.
In Fakir Apparels mainly two types of machines are used. These are Circular
knitting and Flat bed knitting machine. There is three floors in knitting section and
three floor consists of 68 Circular knitting machine & 11 Flat bed knitting
machine. In circular knitting, 5 machine are interlock for interlock production, 17
machine are rib production and rest machines are single jersey machines.

3.2 DYEING SECTION

3.2.1 DYEING
3.2.2 INTRODUCTION:
The objective of dyeing is the uniform coloration of the mass of fibers constituting
the material,
usually to match a pre-specified color. Any significant difference in color from that
requested by the customer, and any unevenness of the color of a fabric, will be
immediately apparent. Many factors can influence the final color appearance.
These include fiber characteristics such as the luster, denier, and staple length,
texture, and cross-section, as well as the cloth construction. Since a client’s colored
sample is rarely of the same material as that to be dyed, dye house laboratories
devote considerable time to dyeing trials aimed at developing recipes to reproduce
the desired color on the given goods. Coloration of a textile material is achieved in
a number of different ways:
1. Direct dyeing, in which the dye in the aqueous solution in contact with the
material is gradually absorbed into the fibers because of its inherent substantively
2. Dyeing with a soluble precursor of the dye, which forms an insoluble pigment
deep within the fibers on treatment after dyeing
3. Direct dyeing followed by chemical reaction of the dye with appropriate groups
in the fiber;
4. Adhesion of the dye or pigment to the surface of the fibers using an appropriate
binder.
All of these methods but the last require that the fibers, at some stage, absorb the
dye, or an appropriate precursor, from an aqueous solution. This process is
essentially reversible. Note, however, that precipitation of a pigment and reaction
with the fiber are irreversible chemical processes.
Theory of Dyeing:
Dyeing theory covers a wide range of subjects mainly in the area of physical
chemistry. As for all theory, the aim is to provide a set of hypotheses that explain
34
©Daffodil International University
Industrial attachment
the behavior of known dyeing systems, and which are capable of predicting what
will happen in a new situation. Dyeing theory has many qualitative aspects that are
useful in explaining practical dyeing, but the physico-chemical measurements on
dyeing processes that provide quantitative data are often far removed from actual
dyeing practice. Some of the subjects included in dyeing theory are:
1. The state of dyes in solution and in the fiber during and after dyeing
2. The rates of dyeing processes and how these are influenced by mass-transfer of
dye from the bath solution to the dye–fiber interface, and by diffusion of the dye
from the interface into the fiber
3. The phenomena occurring at the dye–fiber interface such as dye molecule
adsorption and the effects of surface potentials
4. The nature of the interactions between dye and fiber molecules, which are the
origin of substantively
5. The treatment of dyeing as a thermodynamic equilibrium and its description in
terms of thermodynamic variables
6. The theory of fiber structure and how this influences dyeing rates and
equilibrium.

3.3.5 MARKER SECTION:
In FAL marker is made both manual system & automatic system. In computer
aided marker FAL use INVESTRONICA software. In manual marker making
process, marker man use pattern paper to draw different garments parts in marker
paper.
Fabric spreading is very important part of the production process because it is basic
for obtaining a high quality final product. Spreading is the process of unwinding
large rolls of fabric onto long, wide tables in preparation for cutting each piece of a
garment. The number of layers of fabric is dictated by the number of garments
desired and the fabric thickness. Fabric Spreading Machines are used for bulk
production.
50

Objectives of spreading process:
2. Stepped spreads- this as the name suggests, is built up in steps, with all the plies
in one step having the same length. A stepped spread is generally used when the
quantities to be cut precludes the use of a flat spread. The cut order plan details the
colors and ply lengths for a stepped spread, if it is needed.
1. Alignment of plies in both length and width direction- length and width of
fabric must be at least equal to marker length and width.
4. Correct ply tension- ply tension must be uniform and as much less as possible.
51

Industrial attachment
5. Avoidance of distortion in the spread during cutting- polythene sheets are
used under the bottom ply to resist friction of the bottom ply with the base plate of
the knife.
6. Fabrics must be flat and free from any crinkle & crease- these cause defects
in garments due to variation in dimension.
Cutting is the major operation of the cutting room, when the spread fabric is cut
into garment components. Of all the operations in the cutting room this is the most
decisive, because once the fabric has been cut, very little can be done to rectify
serious mistakes. Cutting can be done manually using powered knives or by
computer-controlled system.

Lapped Seam (LS): Lapped seam is made with two or more pieces of fabric
overlapping each other. LS commonly, but not always, have one ply of fabric fold
under itself for a finished edge.
Bound Seams (BS): Bound seam is made to finish and edge of a garment. A
common example of this would be a neckline of a Crew T.
Flat Seam (FS): A flat seam is constructed by having two pieces of fabric meet
precisely at their edges. A cover stitch is used to sew the two pieces of fabric
together.
Edge Finished Seams (EF): This seam is used to prevent the edges of the fabric
from rolling or curling. Primarily used for knit fabrics and is suitable for straight or
curved seams and edges.
Ornamental Seam (OS): This seam is made using machines with zigzag
capability. It is used on a plain seam on woven or knit fabric.
Factors Affecting Appearance of Seam: The technique and skill of the sewing
machine operators also govern the appearance of sewn seams. Some of the factors
that will adversely affect the appearance of a seam.

The General Rules of Spot Removing:
3. Blot gently — never rub; and don't ever blot with hot water.
Stain Removal:
Ironing:
Ironing is the use of a heated tool (an iron) to remove wrinkles from fabric.
The heating is commonly done to a temperature of 180–220 °Celsius, depending
on the fabric. Ironing works by loosening the bonds between the long-chain
polymer molecules in the fibers of the material. While the molecules are hot,
the fibers are straightened by the weight of the iron, and they hold their new
shape as they cool. Some fabrics, such as cotton, require the addition of water to
loosen the intermolecular bonds.
Do not iron

Confirmation of Quantity:
First step of garment inspection start with confirmation of Quantity with the
vendors packing list by counting all Pecs of each box. If Qty is not matching to
the packing list and written in the box then this discrepancy
discrepancy is informed to the
vendor.
Confirmation of Accessories:
79
Industrial attachment
Next step is the confirmation of accessories,, here we confirm brand tags,
demerit tags, Price tags, or oth
other
er tags, wash care labels, woven labels, or other
labels and accessories as required by the buyer.
After confirmation of accessories all pieces are checked as per size specification
based on the instruction sheet which is given by the buyer side. If any
measurement problem is noticed then we check the original sample and inform
the buyer same time.
In Side Inspection:
At this stage garment is checked from reverse side to ensure that there is no
fabric defect, poor stitching,, and stains etc. in the garment.
At this stage garment is checked from outside to ensure that there is no color
variation, weaving defect, fabric defect,
defect, printing defect, holes, poor stitching,
bad smell , dying defect and stains etc in the garment.
Final Inspection:
Final Inspection stage is the most important part of inspection process, here
garment is rechecked to confirm that inspection is done properly
properly without
missing any checking step if any defect is noticed we put it into rejection bin or
send it for repay.

are used for uniform water supply. These are automatic on-off
on off system motor.
When the pressure is reduced
ced to the desired level (2 bars) then the motor is
turned on. Similarly when the pressure is above the desired level (4 bars) then
the motor is turned off. So, it has variable water supply capacity & supplies
water as required. The water, which is used for
for cooling, is brought to a tank &
again supply by a pump.

Boiler feed water needs special standard. Any deviation from the required
standard may result in scale formation, which eventually reduces the efficiency
of the boiler. This
his ultimately affects the cost of steam generation and makes the
production cost high. To maintain the required standard of the water, there
should be some means to pretreat the boiler feed water.
There are two water softener to pretreat the boiler feed water.
