Textile technology in spinning covers blow room, carding, drawframe comber, speedframe,
ring frame, winding, fibre testing, yarn testing etc. I am a textile technologist , I had the desire to
create a web page on TEXTILE TECHNOLOGY and hence this attempt. With my limited knowledge
on webpage designing,i would like to share some information with you.

Success of business is to maximise the profit. Choosing the right product mix is one way
of maximising the profit. How to choose the product mix? Linear Programming is one among the
solutions. But Unfortunately LP is not being used in the Textile Industry. To read more about LP please click

YARNS

The greatest test of courage on earth is to bear defeat without losing heart

Raw material represents about 50 - 65% of the production cost of a short-staple yarn. There are a number
of fibre properties which can influence the quality of the yarn. A textile fibre is a peculiar object.
Fibre properties vary very much within the lot. Optimal conditions can be obtained only through the
mastery of the rawmaterial. Therefore fibre testing is very very important.

Manage your time as you manage your money

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 fibres used
in the mixing.The technological improvements are remarkable in this process. Important points are highlighted

BLOWROOM PROCESS

Mistakes are the best teachers

High production carding has now become an established practice for short-staple fibres.Production
capacity in recent carding machines can be increased substatially without deterioration in quality.
More information about carding is discussed in this link
CARDING PROCESS
THEORY OF CARDING

Reading without thinking is like eating without digesting

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 fibre at the highest proudction
rates possible, and with the least amount of maintenance.

Drawframe 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 drawframe
sliver determines the final yarn quality.For more information please click

Most problems are really the absence of ideas

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 rawmaterial.More iformation in
COMBING PROCESS

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.Eventhough drawframe 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

Do important jobs now before they become urgent

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 equalled by the new technologies owing to technological reasons. More information in

A pessimist finds difficulty in every opportunity, the optimist finds opportunity in every difficulty

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.

The more time spent on self improvement, the less there is to criticise others.

Variables in a spinning mill is extremely high e.g., rawmaterial, 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 optimise the process parameters to produce a good quality
yarn at a lower manufacturing cost. Some information and guidelines for fixing parameters is given in the
following pages.

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 important characteristics OF yarn is discussed here.

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.
COMPRESSED AIR

You can either be a boss or a leader. Decide.

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 consdiered 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 upto 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
