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.
Some of the main fields of agro-textiles Shade nets Mulch mats Crop covers Anti-hail nets Net for protection from birds Fishing nets
Why agro-textiles? Increasing population pressure Limited resources such as land, water, energy, etc. Increased standard of leaving in general Ecological problems, etc.
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
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.
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
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
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.
Wind shield For protection of fruit plantation from wind particularly in windy area Depending on the plant size or even plantation size, size of the fabric is to be determined. The level of wind that plant can easily withstand and the maximum wind speed attainable in the region to determine fabric structure. continued
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.
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.
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
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
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
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
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.
Projected global market size of technical textiles is US $ 120 to 150 billions. Indian market is about US $6 billion (Rs crores). Agro-textiles form about 1.5% of the technical textile market.
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.
BIS initiative TXD 35 – sectional technical committee for Technical Textiles for Agrotech Applications Some standards have already been approved and some more are in the process
Government of India initiative Steering committee for growth and development of technical textiles under the Chairmanship of the Textile Commissioner, Mumbai Centre of Excellence with SASMIRA, Mumbai as lead partner with MANTRA, Surat and NAU, Navsari as partners.
