Textile technology in spinning covers blow room, carding,
draw frame comber, speed frame,
ring frame, winding, fiber testing, yarn
testing etc. With our limited knowledge
on webpage designing, we would like to share some information with you
Mixing is the first and important process in the spinning process. Some
information regarding "COTTON MIXING", is listed in this page.
COTTON MIXING
| No body can insult you without your
consent |
Blow room is the process which takes care of opening , cleaning and blending
of different fibers used in the mixing. The technological improvements are
remarkable in this process. Important points are highlighted
BLOW ROOM
PROCESS
| Mistakes are the best teachers
|
High production carding has now become an established practice for
short-staple fibers. Production capacity in recent carding machines can be
increased substantially without deterioration in quality.

CARDING

Metallic card clothing played an important role to improve the production
rates on revolving flat cards. High production card would not have been
possible without the Metallic card clothing. Moreover the demand for high
production and high quality from carding machine put wire manufacturers under
pressure to improve their design continuously to meet the requirements.
Modern metallic wire is designed for optimum carding performance during the
processing of many tonnes of fiber at the highest production rates possible,
and with the least amount of maintenance.

Draw frame contributes less than 5% to production cost of yarn. But its
influence on quality is very big, because drawing is the final process of
quality improvement in the spinning mill and quality of draw frame sliver
determines the final yarn quality.

Combing is the process which serves to improve the raw
material. Combed yarn
is stronger, more uniform, has greater shine and is smoother and purer. The
quality improvements are obtained at the cost of additional expenditure on
machines, floor and personnel, together with a loss of raw material.

| The greatest loss is the loss of self-confidence

Roving bobbin is the ideal package form for supply of material to the ring
spinning frame. It is very convenient for transport and storing. Even though
draw frame produces a sliver that already exhibits all the characteristics
required for making the yarn, the roving frame is forced upon a spinner as a
necessary evil for two reasons. They are 1.higher draft 2.drawframe can
feeding creates more problem

The ring spinning will continue to be the most widely used form of spinning
machine in the near future, because ring spinning still offers the greatest
flexibility in application and supplies yarns of a quality that cannot be
equaled by the new technologies owing to technological reasons.

Winding is the process which results in producing a good package of long
length and fault free yarn. Most of the spinning mills use automatic winding
machines. Quality of yarn and package and winding machine production are
improving day by day. The requirements of package quality and yarn quality is
also very high for the present knitters and weavers.

Variables in a spinning mill is extremely high e.g.,
raw material,
atmospheric conditions in a plant type of machines, technology adopted, skill
level, investment concepts, market requirements, etc. Since the variations
are innumerable, it is a must to optimize the process parameters to produce a
good quality yarn at a lower manufacturing cost.

Yarn occupies the intermediate position in the manufacture of fabric from
raw material. Yarn tests are therefore essential, both for estimating the
quality of the raw material and for controlling the fabric produced.

The textile Industry uses compressed air power in some machinery or other,
for instance blow room, comber, spinning frame, loom, splicers to name a few.
With the use of more sophisticated, high production machinery the need for
more and more complicated Pneumatic controls are necessitated. To have minimum breakdowns and reliable performance with minimum failure, in other words, to
have good quality products, the compressed air supplied to the machine
should be of the highest order, both in QUALITY and QUANTITY.

Atmospheric conditions have a decided effect on textile materials,
especially during processing. For this reason it is essential that the
temperature and moisture content of the air within the mill be
controlled. The exact degree of temperature and relative humidity will vary
depending upon the material and department.

Spinning Industry was
considered to be a Labour intensive unit. But now it is considered
to be a power intensive unit due to automation and increasing power cost. Moreover
a spinning unit uses a lot of Induction motors of capacity ranging from 0.25 KW
up to 70KW ,
a lot of Electronic components like DC Drives, PLC controls, Processors, Inverters, SCRs etc. Hence
it is a basic requirement for the technologist to understand the basics of
Electrical, Electronics and Power etc
