| Cotton
Information |
|
Cotton is cultivated in 75
Countries with an area of 32 Million Hectares. Cultivation period varies from
175 days to 225 days depending on variety. Cotton is harvested in two seasons,
summer and winter seasons. Saw ginned cotton is more
uniform and cleaner than Roller Ginned Cotton. But fibers quality is retained
better quality in Roller Ginning than Saw Ginning which has high productivity.

| Cotton Fiber |

Improvements in fiber quality can take many different forms. Changes in
length, strength, uniformity, and fineness In one recent analysis,
fiber perimeter was shown to be the single quantitative trait of the fiber
that affects all other traits . Fiber perimeter is the variable that has the
greatest affect on fiber elongation and strength properties. While mature dead
fibers have an elliptical morphology, living fibers have a cylindrical
morphology during growth and development. Geometrically, perimeter is directly
determined by diameter (perimeter = diameter × p). Thus, fiber diameter is the only variable that
directly affects perimeter. For this reason, understanding the biological
mechanisms that regulate fiber diameter is important for the long-term
improvement of cotton.

| Cotton
Length |
|
The
"length" of cotton fibers is a property of commercial value as the price is
generally based on this character. To some extent it is true, as other factors
being equal, longer cottons give better spinning performance than shorter ones.
But the length of a cotton is an indefinite quantity, as the fibers, even in a
small random bunch of a cotton, vary enormously in length.

| Fiber Testing |
|
Raw material represents about 50 to 70% of the
production cost of a short-staple yarn. This fact is sufficient to indicate the
significance of the raw material for the yarn producer. It is not possible to use a
problem-free raw material always , because cotton is a natural fiber and there are many
properties which will affect the performance. If all the properties have to be good for
the cotton, the raw material would be too expensive. To produce a good yarn with this
difficulties, an intimate knowledge of the raw material and its behavior in processing is
a must. Read More | Print |

| Effect Of Cotton
Fiber Length |
|
The prediction
of yarn quality based on the technological characteristics of the raw material has been
improved by the use of the AFIS. Unfortunately, information about distributions of fiber
properties that are measured by the AFIS is generally not used. The studies carried out at
the ITC show that the AFIS length distribution is variety related. In addition, the
percentages of both the shortest and the longest fibers have an important impact on yarn
quality. Read More | Print |

| Effect Of Cotton
Preparation |
| Cotton processing machines
that mechanically work the cotton fiber from bale to yarn are designed with the intent of
minimizing fiber damage. Nevertheless, opening, cleaning and blending equipment shorten
the staple length while increasing short fiber content and neps. Carding and combing
reverse this by removing a percentage of the short fibers and neps. Drawing is thought to
have a minimal effect on fiber physicals, its purpose being to improve sliver evenness and
fiber orientation.

| Costing For Spinning
Mills |
|
It is better to review the basics concepts, costing methods and
techniques and elements of costing before we work out a costing for a spinning
mill. Cost accounting is a system of determining the costs of products or
services. It has primarily developed to meet the needs of management. It
provides detailed cost information to various levels of management for efficient
performance of their functions.
