INTORDUCTION
Human basic needs
Food
Clothing
Shelter
Technical textile
Technical performance and functional properties
Classified according to end use
Agro textiles
Application of textile materials in the agriculture field

AGRO TEXTILES
Special textiles that are manufactured for agricultural
applications
The four sectors combined together are popularly called as
“Agrotech” sector
– Agriculture
– Horticulture
– Forestry
– Fishing

Properties Required for Agro Textiles
Resistance to solar-radiation
Resistance to ultraviolet radiation
Biodegradability
High potential to retain water
Protection property

Fibres In Agro Textiles
Fibers used in agro textiles are as follows
Nylon
Polyester
Polyethylene
Polypropylene
Jute
Wool

Factors Influencing
Sunlight – direct and indirect
Water
Climatic Conditions including wind, hail, humidity
External factors like birds, insects, weeds
Post Harvest handling of produce – storage and packaging

Shade Nets/Fabrics
The shade nets provide protection
- to the plants from wind,
- extreme weather conditions &
- reduce water evaporation
Polypropylene or HDPE in knitted or woven form
Grape cultivation, orchid plantations, tea plantations, nurseries
Shade percentage depends upon the application - 25% to
95%
Vignesh Dhanabalan - [email protected]
Anti-bird Nets
Designed to exclude the
birds
Allow movement of bees
and keeps shade to a
minimum
Polypropylene or HDPE
monofilament yarn (UV
stabilised) and knitted
Vignesh Dhanabalan - [email protected]
Anti- Hailstone Nets
To prevent from hail
damage
It helps shield vines from
the fruit damage and
defoliation
Orchard hail protection
Vineyard hail protection
Vignesh Dhanabalan - [email protected]
Weed Control Fabric
Prevents the growth and spread of weed
Fabric promotes rapid and even plant growth and maintains higher soil temperatures
This fabric is water permeable, it allows the soil to get warm, minimizes non-productive evaporation and prevents creation of soil crust
Vignesh Dhanabalan - [email protected]
Harvesting Nets
Harvesting nets are perfect
for collecting fruits which
fall off the tree when they
are ripe
Placed underneath the
trees until the harvesting
period is over
Polyethylene monofilaments
Vignesh Dhanabalan - [email protected]
Wind Protection Nets
Used to protect fields of young
plants, trees or the harvest from
being damaged by the wind
Reduce the effects of high winds
and even help to keep out
airborne sand and salt in areas
close to the sea
Reduce the wind speed and
increase the orchard temperature
Vignesh Dhanabalan - [email protected]
Structural Wind Protection
Reduces the heating and
cooling costs by 10 – 40% in
a greenhouse
Orchard wind control
Protect the orchard from
damaging effects of wind,
evaporation, fruit bruising,
blossom and leaf damage,
wind rub and shoot tip
scorching. Vignesh Dhanabalan - [email protected]
Greenhouse Covers
The green house covers are
useful in nursery raising
The covers are made of highly resistant to ripping, waterproof and UV resistant material
It improve the greenhouse microclimate and heating costs, shield crops from cold winds and rain
Vignesh Dhanabalan - [email protected]
Insect Repellent Meshes
Protect plants from insect attack
The insect meshes can also be
used as a crops cover, screens for
glasshouse doors and ventilation
windows, greenhouse internal
covers
Polyethylene monofilament
meshes
Vignesh Dhanabalan - [email protected]
Temperature Controlled Fabric
Protects the crops from
cold, frost, insects, wind and
rain.
The temperature controlled
fabric captures heat on
sunny days, retain heat
radiation from ground at
night and also block night
time winds.
Vignesh Dhanabalan - [email protected]
Tree Shelters
The tree shelter fabric
protects young trees from
animal damage, drying
winds, defoliation and tip
scorching.
A sheltered tree grows
faster and healthier, as the
water retention is improved,
whereas the evaporation is
reduced
Vignesh Dhanabalan - [email protected]
Packing Materials for Agri-Goods
Packing sacks for
vegetables.
Tubular packing nets for
fruits
Net structures are
preferred because of their
high strength, low weight,
air permeability and
cheapness
Vignesh Dhanabalan - [email protected]
Fishing Nets
Fishing nets are knitted
fabrics used for marine and
inland fishing
The basic characteristics for
fishnets are transparency
and invisibility in water
Vignesh Dhanabalan - [email protected]
Agro- Protective Garments
Protecting farmers from
harmful pesticides during
farming
Lightweight and cheaper
Protect from pesticides
Good breathable property
and readily washable
Vignesh Dhanabalan - [email protected]
Animal Husbandry
Filtering of milk in an
automatic milking system
Identification belts of
polyester and nylon
material for animals
identification
Underlay to reduce the
mud on cattle paths and
trails.
Support for udders
Vignesh Dhanabalan - [email protected]
USE OF COIR IN AGRICULTURAL
TEXTILES
Bio Roll
Basket Liners
Mulch Blankets
Erosion Control Blankets For Controlling Slope Erosions
Roof Greening Mats
Grow Sticks
Coco Logs
Grow Media

INDIAN AGRICULTURE INDUSTRY
"Agriculture is the backbone of our country“
"Textile can be the backbone of Agriculture?"
Vignesh Dhanabalan - [email protected]
Reasons for Low productivity of Indian
Agriculture
Overregulation of agriculture has increased costs and price
risks
Government intervenes in labour, land, and credit markets
Inefficient infrastructure for irrigation literacy,
Socio-economic backwardness & no land reforms
Inadequate finance and marketing services for farm produce
The average size of land holdings is small & fragmented
Inadequate adoption of modern agricultural practices

India is the world’s largest producer of bananas but
we have not yet produced the fruit which is of
international standard.
Vignesh Dhanabalan - [email protected]
Increased Organization of Agriculture Will Boost
Use of Agrotextiles
India’s organized retail in food and grocery has attracted a
number of large business houses – including ITC, Bharti, Reliance
and Godrej – to agriculture
Acquired land in various parts of the country and are working
closely with the farmers
Vignesh Dhanabalan - [email protected]
Government Intervention Needed
Unimin India exports 99% of its agrotextile products.
PVD Plastmould exports a great deal of its production.
Seeds, fertilizers, power and water – are subsidized for the
Indian farming sector.

CONCLUSION
"Textile is a global text which has the extra style
of applications in all fields, - feel it and endure it"!!!
