What is agro-textiles? All the textile goods intended
for use in the agrarian production encompassing agriculture, horticulture, animal husbandry and forestry can be considered as agro-textiles.
![Page 3: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/3.jpg)
Some of the main fields of agro-textiles Shade nets
Mulch mats Crop covers Anti-hail nets Net for protection from
birds Fishing nets
![Page 4: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/4.jpg)
Why agro-textiles?
Increasing population pressure
Limited resources such as land, water, energy, etc.
Increased standard of leaving in general
Ecological problems, etc.
![Page 5: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/5.jpg)
Why agro-textiles?
Can control climate, ecological degradation, efficient use of water, reduce use of herbicides, save energy, improve product quality, etc.

Different forms of agro-textiles Nets Sheets Woven fabrics Non-woven fabrics Knitted fabrics Coated composites

Requirements for qualifying as standards for agro-tech use
![Page 8: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/8.jpg)
Sunscreen
Quality of nets required will depend on the amount of sunlight required for the crop as compared to that available in a given area.
![Page 9: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/9.jpg)
Net for protection from birds Open structure with minimal
shading Net opening sufficiently small so as
to not allow birds damaging the crop
Made from material sufficiently strong for birds not to be able to cut open the net
Able to withstand sun, wind, rain in the region
![Page 10: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/10.jpg)
Plant net For fruits growing close to the
ground Separate damp soil from fruits to
keep the amount of fruit decay to minimum
Should restrict the moisture reaching fruits
Maximum allowable level of moisture transmission through the fabric to be decided on the behaviour of the fruit under protection
![Page 11: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/11.jpg)
Mulch mat/ ground cover Moisture and heat
transportation behaviour of the fabric should be studied.
Amount of light allowed to pass through should also be measured. It should be ideally zero not allowing any weeds to get light for development.
![Page 12: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/12.jpg)
Wind shield
![Page 13: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/13.jpg)
Wind shield
Fabric structure to sufficiently dampen the wind speed from maximum available in the area to the level which the plant concerned can withstand.
Accordingly, fabric air permeability and strength requirement are to be determined.
![Page 14: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/14.jpg)
Root ball net
Should have sufficiently open structure to allow roots to grow through.
Should be bio-degradable over a period of time, may be, a few months when underground.
![Page 15: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/15.jpg)
Meshes for protection from insects To keep out harmful insects
from entering green houses and tunnels
To keep pollinating insects inside
Mesh fineness to be adjusted accordingly
Mesh material to be strong enough for insects to be not able to destroy it
![Page 16: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/16.jpg)
Tuft protection net
To prevent removal of earth in lumps during animal grazing in grassy areas of river banks
Should allow the grass to grow but give sufficient strength to ground so that earth is not removed with the movement of animals
![Page 17: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/17.jpg)
Crop/ plant covers
Specifically designed to tackle weather damage – especially during the blossom, stoning and fruit ripening period.
Protection offered should be from frost, rain, hail and wind.
Should be tough with a high degree of UV stabilisation and suppleness for ease of handling
![Page 18: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/18.jpg)
Packaging materials for agricultural products Packaging sack for vegetables Tubular packing nets for fruits Textile reinforced boxes for
transportation of fruits and vegetables
Should give strength and stability to the package able to withstand the forces during transportation
![Page 19: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/19.jpg)
Almost all fabrics need UV stabilisation to increase the working life of fabrics.
Also, they should have anti-microbial as well as anti-insect/ pest treatments which are crop/ place dependent.
![Page 20: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/20.jpg)
Projected global market size of technical textiles is US $ 120 to 150 billions.
Indian market is about US $6 billion (Rs. 30000 crores).
Agro-textiles form about 1.5% of the technical textile market.
![Page 21: Dr.R.P.Nachane Principal Scientist and Head, QEID CIRCOT, Mumbai.](https://reader035.fdocuments.in/reader035/viewer/2022081504/56649ca85503460f9496ac2f/html5/thumbnails/21.jpg)
Man made /synthetic fibres
are mainly used in technical
textiles due to their
favourable price/performance
ratio, ease of transportation
and setup, saving in storage
space and long service life.
