The document discusses the process of fabric manufacturing from yarn production through several steps. There are three basic steps: 1) yarn production where fibers are spun into threads, 2) weaving or knitting where yarns are interlaced or looped to form fabric, and 3) further processing like bleaching, dyeing, and finishing to produce the final fabric. It then focuses on different types of knitting, including weft and warp knitting, and finishing processes like ironing, folding, and cartoning of knitwear products. The knitwear industry in Bangladesh is mainly located in the Narayanganj district.

5. Composite crystals contain at least two components,
which have different unit cells within the same
crystal. Since the unit cells differ in volume by an in
general non-integer factor, composite crystals are
usually non-stoichiometric, and their occurence is
related to the mixed valency of at least one of the
components. Composite crystals therefore tend to
have unusual solid state properties. Since there is a
mutual interaction between the two components,
each of the sub-lattices undergoes a distortion with
the periodicity of the other component. Several
examples of low-dimensional organic composite
structures based on BEDT-TTF and its tetra-oxygen
analog BEDO-TTF are discussed.

7. There are three basic steps required for fabric
production. The first step in creating fabric is yarn
production. Here, the raw materials that have been
harvested and processed are transformed from raw
fibers into yarn and threads. This is done by spinning
the fibers. Spinning can be done by hand, but this
process is quite tedious and time consuming. These
days, the vast majority of spinning is done by
spinning wheel. The fibers are drawn across the
wheel, and as it spins, the fibers are collected on a
cylindrical object called a bobbin. The bobbin holds
the spun fibers, which are now connected into a long
strand of thread or yarn. In the next step, the bobbins
will be transferred to another machine, where the
yarn will continue on its journey into fabric.

8. This is a process of Fabric Manufacturing By
Converting yarn Into Loop And These loops are
Interloped/Interlocked/Intermeshed Together
Which Form A Structure Is Called Knitting.
Knitwear : The Apparel Which We Get By
Knitted Structure Is Called Knitwear.

9. ❖ Weft Knitting :Weft knitting is
a knitted piece of fabric where
the stitches run from left to
right horizontally across
the fabric. It is usually
knitted with one piece of
yarn, and can be made
either by hand or using a
knitting machine. Weft
knitting is the most
common form of knitting
as it is simpler than warp
knitting.
 Warp Knitting :The arranging of
yarn threads in long parallel
lengths of equal tension, onto a
beam in preparation for
weaving.
 During the warping process
cones of yarn are placed onto a
rack called a creel. From this
creel yarn passes through
tension and spacing devices and
through a leasing reed which
separates the yarn threads and
keeps them in the correct order
before being wound onto a
warping balloon.

10. A knitted fabric consist of forming yarn(s) into loops, each
of which is typically only released after a succeeding loop
has been formed and intermeshed with it so that a secure
ground loop structure is achieved.

11. FLAT CIRCULAR
Flat knit is made with a machine that
knits the fabric in sheets (or flat) and
the gauge is 2 to 10.
Flat knit is thick sweater fabric like
our grandma makes sitting in a
rocking chair with two needle-sticks.
Circular knit is made with a
machine that knits the fabric in
a continuous circle (tube); the
weight is “light.” The fabric is
thin. T-shirt fabric is the best
example of circular knit fabric.

13. Woven fabric does not stretch except on the bias. Woven fabric is
made up of fibers which run straight at ninety degree angles to
each other.
Knit fabric has loops of fiber that allow the fabric to stretch. The
amount of stretch and the direction of stretch are all variables. A
knit may stretch in one direction or it may stretch in both
directions. This is an important consideration when choosing fabric
for a specific pattern. For example; A bathing suit pattern will
require equal two way stretch. If you choose a fabric that only
stretches in one direction, the suit is not going to fit properly... if
you can even get it on.
Unless the fabric is a mashed fiber, such as felt, it has a lengthwise.
A crosswise And a bias grain. Understanding fabric grain is
important when laying out a pattern.

15. The process of applying color to fiber stock, yarn or fabric is
called dyeing. There may or may not be thorough penetration
of the colorant into the fibers or yarns.
Dyes can be used on vegetable, animal or man made fibers only
if they have affinity to them. Textile dyes include acid dyes,
used mainly for dyeing wool, silk and nylon and direct or
substantive dyes, which have a strong affinity for cellulose
fibers. Mordant dyes require the addition of chemical
substances, such as salts to give them an affinity for the
material being dyed. They are applied to cellulose fibers, wool
or silk after such materials have been treated with metal salts.
Sulfur dyes, used to dye cellulose, are inexpensive, but produce
colors lacking brilliance.

17. The Dyes are always
done in backside of
the fabric. The work
is done because of
there is no problem
can take place in
leveling process. Is
any problem take
place in backpart It
is possible to dye
Again.

18. This Process is take
place to remove
natural color, fax, oil,
forein substance. It
takes 30/40 minutes to
increase the fineness.
Squeezer is done for the
2nd time to increase
Fineness.

19. Textile bleaching is one of the stages in the manufacture of textiles. All raw
textile materials, when they are in natural form, are known as 'greige' material
(pronounced grey-shed). This greige material will have its natural color, odor
and impurities that are not suitable for clothing materials. Not only the natural
impurities will remain on the greige material but also the add-ons that were
made during its cultivation, growth and manufacture in the form of pesticides,
fungicides, worm killers, sizes, lubricants, etc. The removal of these natural
coloring matters and add-ons during the previous state of manufacturing is
called scouring and bleaching.

20. After bleaching the dyeing process will
take place as per buyer requirement. Color
mixing is also a part of this process. Dyeing
Duration for Light Fabric is (6-8)hrs. Deep
color like (Meron, Purple)
Can take up to (8-12)hrs. It can take more
time if the shape does not match.

21. The Wet Output Of Dyeing is Used as input of
finishing is Process. This work is done by a
machine named Squeezer. The Manufacturer of
this machine is Dong Nam. Which is produced by
Taiwan.
Also the shrinkage is maintained in this process.
The fabric normally decreases after this process. It
may be increased but this is too much rare.

22. The quality control process is divided into three
separate processes, ensuring that specialized
expertise is applied to each stage of our operation.
This system also provides the redundancy
necessary to prevent any quality problem from
evading detection.

33. knitwear firms in Bangladesh are mainly located in
Narayanganj district. Besides, a
few firms are also located in Chittagong, Dhaka, an
d Gazipur districts. The knitwear industry
in Narayanganj emerged at the early stage of the 19Th century.
Initially clothes were knitted
from thread processed by wooden spindle wheels. Later handlooms were
brought in from
India. This transformed the local cloth industry in
to a specialized sector of hosiery items. The
hosiery sector expanded and accelerated in the 1980s
and 1990s into knitting industry when
the expansion of RMG industry created demand for fabrics. The industry
expanded both
vertically and horizontally to meet growing demand
for fabrics within a few years.
