LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

8. Introduction
Cotton is a cool, soft, comfortable and is the principal clothing fiber of the
world. This fabric absorbs and releases perspiration quickly, thus allowing
the fabric to “breath.” Cotton provides absorbency and consequent
comfort.
The advantages of polyester over cotton fibers are its strength, lustre,
easy-care, price, consistency in quality and ready availability. But, it has
low moisture regain 0.4% as compared to cotton 8%. The polyester fabric
will absorb and wick less water.
There is no perfect fiber that contains all the qualities of cotton and
polyester mentioned above. In this context, blending is the technique to
combine fibers which emphasizes the good qualities and minimizes poor
qualities of the fibers. Blending also makes the fabric manufacturing
process economical. The price of man-made fiber is much more stable. In
blends of polyester/cotton, the fibers provide crease recovery,
dimensional stability, tensile strength, abrasion resistance, moisture
absorption, drape ability, etc.
Our project title is
“Effect of Blend Ratio on Quality of Polyester/Cotton Yarns”.
9. Here, the properties of P/C blend yarns are compared with the same
of 100% cotton yarn and the results are discussed in terms of the
following quality parameters:
CVm% and Um%: Mass irregularity (CV% and U% ).
Thick, Thin & Neps
IPI: Imperfection Index
CSP and single yarn strength.
Hairiness
To incorporate the advantageous points of both cotton and PET
fibers, different blend ratios of P/C have been tried and the ratio
65/35 is widely used commercially. In this work, we tried to check
the yarn characteristics with several P/C blend ratios.
10. AIM OF THE PROJECT
To compare different blend ratio of Polyester/Cotton yarn in
terms of yarn quality parameters such as CVm% and Um%, Thick,
Thin, Neps, IPI, CSP, Hairiness, Single yarn strength by which we
can find out the best quality blended yarn of 30/s Ne.
12. COTTON
FIBER
• Cotton is defined as white fibrous substance
covering seeds harvested from Cotton Plant.
No other fiber comes close to duplicating all
of the desirable characteristics combined in
cotton. Cotton Fiber is having a tubular
structure in twisted form. Now researchers
have developed colored cotton also. No
other material is quite like cotton. It is the
most important of all natural fibers,
accounting for half of all the fibers used by
the world's textile industry. Cotton has
many qualities that make it the best choice
for countless uses:
• Cotton fibers have a natural twist that
makes them so suitable for spinning into a
very strong yarn.
• Cotton fabric is soft and comfortable to
wear close to skin because of its good
moisture absorption qualities.
• Charges of static electricity do not build up
readily on the clothes.

15. FIBER MATURITY
The cotton fiber consists of cell wall &lumen. Schenek suggest that
a fiber is to be considered as ripe when the cell wall of the
moisture –swollen fiber represents 50-80 % of the round x-section,
as unripe when it represents 30-40% &as dead when it represents
less than 25%.
NEPPINESS
Neppiness may be due to entanglement of fibers in ginning
process or immature fibers. Entangled fibers can be sorted out by
careful processing But, Neps due to immature fiber will stay on in
the end product and cause the level of Yarn defects to go higher.
16. POLYESTER
FIBER
• Polyester is a term often defined as
“long-chain polymers chemically
composed of at least 85% by weight of
an ester and a dihydric alcohol and a
terephthalic acid”. In other words, it
means the linking of several esters
within the fibers. Reaction of alcohol
with carboxylic acid results in the
formation of esters.
• Polyester also refers to the various
polymers in which the backbones are
formed by the “esterification
condensation of polyfunctional alcohols
and acids”.
• Polyester can also be classified as
saturated and unsaturated polyesters.
17. Properties of Polyester Fiber
Cut Length
Cut lengths available are 32,38,44,51 and 64 mm for cotton type
spinning. The most common length is 38 mm.
Tenacity
Elongation
Tenacity (gpd) High Tenacity Normal Tenacity Staple

Elongation (%) High Tenacity Normal Tenacity Staple
Dry 12.5-7.5 25-15 40-25
Wet 12.5-7.5 25-15 40-25
Density 1.38 1.38 1.38
18. Moisture Regain
At 65% RH and 70 ºF, Polyester moisture regain is less than0.4%.
Because of low moisture regain it develops static charge. Garments of
polyester fibers get soiled easily during wear.
Thermal Properties
Polyester fibers are most thermally stable of all synthetic fibers. As with
all thermoplastic fibers, its tenacity decreases and elongation increases
with rise in temperature. When ignited, polyester fiber burns with
difficulty.
Shrinkage
Polyester shrinks approx 7% when immersed in an unrestrained state in
boiling water. Like other textile fibers, polyester fibers undergo
degradation when exposed to sunlight.
Its biological resistance is good as it is not a nutrient for micro
organisms.
19. Swelling & Dissolving
The fibers swell in 2% Solution of Benzoic Acid, Salicylic Acid and
phenol.
Alcohols, Ketones, Soaps, Detergents and dry-cleaning solvents have
no chemical action on Polyester fiber.
Chemical Resistance
Polyester fibers have a high resistance to organic and mineral acids.
Weak acids do not harm even at boil. Similarly strong acids including
hydrofluoric acids do not attack the fibers appreciably in the cold.
20. • Resists abrasion (but can "pill")
• Very resilient (springs back into shape)
• Resist wrinkling
• Very high heat can "melt" the fabric
• The right amount of heat can be used to permanently "heat set".
• Easy to wash and wear
• Does not absorb water (can be uncomfortable when worn next to the skin
in warm weather unless loosely woven)
• Dries quickly
• Attracts static electricity which also attracts dirt and lint
• Although they do not absorb water, they do absorb oil and grease. This
means synthetics.
• Resist soiling, but once oil based stain soaks in, it can be difficult to clean.
• Strong fiber (but nylon is stronger)
• Often blended with cotton or even wool to add crease resistance
• Polyester does not absorb water, but it can be produced in such (as in
polypropylene and microfibers) as to "wick" water away from the skin.
Characteristics of Polyester Fibers and Products
21. BLENDED
FIBER
• Blending of fibers is usually made with
different fibers having dissimilarity in their
properties, with a view to achieving or
improving certain characters of the yarn or
its processing performances. Fabric produced
from the blended yarn might have better
characteristics than what could be obtained
in a fabric produced from a single fiber. The
blending of cotton is done to develop drape
properties, comfort ability, durability, dye
ability and many other properties of the
fabric products.
• In the cotton/polyester blends, polyester
fiber plays a vital role in the textile
applications in all areas from the lifesaving
medical textiles to the geo-textiles. The
advantages of polyester over other fibers are
strength, lustre, aesthetics, economics,
consistency in quality and ready availability.
22. OBJECTS OF BLENDING
In the cotton spinning process, blending has the main objective of yarn
manufacture with good quality at a reasonable cost. It also helps in
processing of following stages.
• Carding
• Spinning
• Warping and Weaving
• Dyeing and Finishing
REQUIREMENTS FOR SUCCESSIVE BLENDING
Successful blending depends on obtaining an intimacy of blending.
Theoretically in a blend single fiber units are distributed at random
throughout the x-section of the yarn. Some important requirements are as
follows:
1. Properties of fiber
2. Atmospheric condition
3. Good working conditions of machines
23. TYPES OF BLENDING
• Bale Blending (6-60 bales)
• Flock Blending
• Lap Blending (4-6 laps)
• Web Blending
• Sliver Blending
• Fiber Blending
• Roving Blending

shows that an increase in
polyester proportion decreases
the hairiness of the yarn.
We hereby infer that increase
in polyester proportion on
Yarns have much lower
hairiness than lower proportion
of polyester on yarns and that
the increase proportion of
polyester brings down yarn
hairiness to an appreciable
extent. An explanation to this
phenomenon may be found in

of the various blend ratio yarns.
The graph reveals that increase in
polyester proportion increases the
yarn strength.
We hereby infer that increase
in polyester proportion on
Yarns have much higher CSP
than lower proportion of
polyester on yarns and that the
increase proportion of
polyester brings up yarn CSP to
an appreciable extent. An
explanation to this
phenomenon may be found in

49. While doing this project work we have faced various problems.
Those are given below.
We tried to add various blend ratio (polyester more than 50%) but it was not
possible to spin such yarns during our training period.
Printer of single yarn strength tester was out-of-order so that we could not
print the test result and could not attach with this report. But we noted the
results.
LIMITATIONS
50. In conclusion, we can say that with the increase in polyester% in blend yarn,
the quality parameters of yarns improved. Some of them are U/CV%, IPI,
Hairiness, CSP and single yarn strength. At the same time, moisture
regain% of the yarns decreased; for 100% cotton: 8.4%, 40/60 PC: 5.7% and
50/50: 5.0%. However, depending on the end uses, the optimum percentage
of polyester and cotton may be adjusted.
This project work has given us insight knowledge for producing blend yarns
by manipulating fibre%.
