2. Spinning
• The formation of yarn from fibers by
spinning becomes possible when they
have surfaces of cohesiveness.
Flexibility permits the fibers to be twisted
around one another.

5. Ginnig & Mixxing
• Ginning –The
primary object of the
Ginning is to
separate the fibers
from cotton seed.
• Separated fibers are
mixed and goes to
blow room process.

6. Blowroom
• Basic operations in the
blowroom:
-Blow Room involves a
set of machinery which
opens and cleans the raw
cotton opening
-cleaning
-mixing or blending
-microdust removal
-uniform feed to the
carding machine
-Recycling the waste

7. Carding
• THE PURPOSE OF
CARDING:
Before the raw stock can be
made into yarn, the
remaining impurities must
be removed, the fibers must
be disentangled, and they
must be straightened. This
straightening process puts
the fibers into a somewhat
parallel lengthwise
alignment.The initial process
of arranging the fibers in
parallel fashion is known as
carding.The result from the
carding machine is called as
card sliver.

8. Combing
• The process of
straightening and
parallelisings of fibers
and the removal of short
fibers and impurities by
using a comb on combs
assisted by brushes and
rollers is called combing.
The combing process

9. Draw frame
• Drawframe is a very critical
machine in the spinning
process. It's influence on
quality, especially on
evenness is very big.If
drawframe is not set
properly, it will also result in
drop in yarn strength and
yarn elongation at break.The
faults in the sliver that
come out of drawframe can
not be corrected . It will pass
into the yarn

10. Roving Frame/Speed Frame
• The bobbins are placed on the
roving frame, where further
drawing out and twisting take
place until the cotton stock is
about the diameter of a pencil
lead. There are two stages in
roving: intermediate and fine.
The operations are identical.
Roving is the final product of
several drawing-out operations.
It is the preparatory stage for
the final insertion of twist.

11. Rotor/Open end spinning
• Coarser yarn are made
on open end from 4s to
30s.
• Rotor yarn is mainly used
in Denim, Sheeting,
Home furnishing and
Terry towels.

12. Ring Spinning
• Spinning process is done by
the machine called Ring
frame. Ring frame converts
the bobbin into a yarn. The
bobbin taken from the
previous process Fly frame
is mounted on Ring frame
either automatically or
manually. The Ring frame
stretches the material using
a drafting 2s to 140s
• Ring yarn is finer then open
end
• It has more hairiness as
compare to open end

13. Types of spinning
• The roving, on bobbins, is placed in the spinning frame, where it passes through several sets of rollers
running at successively higher rates of speed and is finally drawn out to yarn of the size desired. Spinning
machines are of
• two types: ring frame and mule frame. The ring frame is faster process, but produces relatively coarse yarn.
For very fine yarns the mule frames are used.
• As the fibers pass through these processes, they are successfully formed into lap, sliver, roving and finally
yarn. Fibers may be blended during the spinning process. The blending procedure varies with its
compatibility with the particular spinning techniques listed below:
•  Open-end spinning
•  Friction spinning
•  Self-Twist spinning
•  Electrostatic spinning
•  Vortex spinning
•  Air-jet spinning
•  Twistless spinning
•  Wet spinning
•  Dry spinning
•  Melt spinning
•  Bicomponent spinning
•  Bicostituent spinning
•  Film splitting
•  Integrated Composite spinning
•  Coverspun
•  Selfil
•  Aerodynamic spinning

14. TYPES OF YARNS
• There are various types of yarns, having its own characteristics. These
characteristics vary according to the construction and treatment given in
the manufacture of yarn. The different types of yarns are listed below:
•  Ply yarns
•  Cabled yarns
•  Doubled yarns
•  Novelty yarns
•  Slub yarns
•  Flake yarns
•  Spiral yarns
•  Ratine yarns
•  Boucle, loop or curl yarns
•  Nub, Knop, Knot or Spot yarns
•  Chenille yarns
