Agriculture, forestry, horticulture, floriculture, fishing segments, landscape gardening, animal husbandry, aquaculture and agro-engineering all these sectors combined together are popularly called as Agro-tech sector. Agro textiles are the application of textile materials in those sectors. It is a very much important segment of Technical Textile. The word “AGRO TEXTILES” is now used to classify the woven, non-woven and knitted fabrics, applied for Agro tech industries including livestock protection, shading, weed and insect control and extension of the growing season. With the continuous increase in population worldwide, stress on agricultural crops has increased. So it is necessary to increase the yield and quality of agro-products. But it is not possible to meet fully with the traditionally adopted ways of using pesticides and herbicides. Today, agriculture and horticulture has realized the need of tomorrow and opting for various technologies to get higher overall yield, quality and tasty agro-products. [Ref- 1 & 3]

Fibers Used in Agro Textiles:
Man made (synthetic) fibers are preferred for agricultural product than the natural fibers due to their high strength, durability and other suitable properties of agricultural applications. On the other hand natural fiber based agro-textiles not only serve the specific purpose but also after some year degrade and act as natural fertilizers.

Fibers used in agro tech industries are as follows:

  1. Nylon
  2. Polyester
  3. Polyethylene
  4. Polyolefin
  5. Polypropylene
  6. Jute
  7. Wool
  8. Coir
  9. Sisal
  10. Flax
  11. Hemp

Though man made fibers (like poly-olefins) are preferred for agro-textiles than the natural fibers mainly due to their favorable price performance ratio, light weight with high strength and long service life, but natural fibers can be used in agro-textiles in some specific arena where characteristics like high moisture retention, wet strength, biodegradability are effectively exploited.

Properties Required for Agrotextiles:

1. Tensile Strength: The tensile strength of shade nets can be a deciding factor of its long term durability and service life. Hence good tensile strength is necessary parameter for shade nets.

2. Withstands solar radiation: Agro textiles are laid over the cultivated areas immediately after sowing or planting. For such application Agro-textiles has to withstand solar radiation with varying surrounding temperature.

3. Withstands ultraviolet radiation: The Non visible radiations include ultraviolet radiations (UV) radiation leads to degradation of molecular chains. No single material is resistant to all radiations .polypropylene and polyester are more resistant to UV radiations when used as an outdoor material, polyethylene is treated with the appropriate UV stabilizers. Potential to reduce the impact of UV radiation on plants by light absorbing or light‐reflecting non-woven (light permeability: 80 to 90% to allow photosynthesis to take place).

4. Bio degradability: Natural fibers like wool, jute, cotton are also used where the bio-degradability of product is essential. Natural polymer gives the advantage of bio-degradation but has low service life when compared to the synthetics.

5. Abrasion Resistance: The abrasion to which a shade net is subjected may be of the material itself (material to material) or stray animals. Abrasion of the shade net would result in holes though which animals and pests could enter the structure and harm the crops .good abrasion resistance is required of shade nets.

6. High potential to retain water: This is achieved by means of fiber materials which allow taking in much water and by filling in super-absorbers. While non-wovens meant for the covering of plants show a mass per unit area of 15 to 60 gm/m2, values between 100 and 500 g/m2 are reached with materials for use on embankments and slopes.

7. Protection property: It must have the properties of protection from wind and creation of a micro‐climate between the ground and the non-woven, which results in temperature and humidity being balanced out. At the same time, temperatures in the root area rise. This is what causes earlier harvests, sufficient stiffness, flexibility, evenness, elasticity, biodegradability, dimensional stability and resistance to wetness. Fungicidal finish (up to 2% of the total mass), which avoids soil contamination.

8. Resistance to microorganisms: It must resistant to microorganism to protect the living being.

9. Stable construction: The construction must be such that it must be stable for any application.

10. Lightweight: The weight of the fabric should be such that it will bare by the plant.

History of Agro Textile:
Agriculture is the backbone of our country. Now it is saying that textile can be the backbone of agriculture. Textile fabrics have a long history of use in agro-tech sectors to protect, gather and store products. Between the 18th century and the end of the 19th century, agricultural development was occurred, which saw a massive and rapid increase in agricultural productivity and vast improvements in farm technology. From then, Textiles have always been used extensively in the course of food production, most notably by the fishing industry in the form of nets, ropes and lines but also by agriculture and horticulture for a variety of covering, protection and containment applications.

However, modern textile materials are also opening up new applications. Lightweight Spun bonded fleeces are now used for shading, thermal insulation and weed suppression. Heavier non-woven, knitted and woven constructions are employed for wind and hail protection. Fibrillated and extruded nets are replacing traditional baler twine for wrapping modern circular bales. Capillary non-woven matting is used in horticulture to distribute moisture to growing plants. Seeds themselves can be incorporated into such matting along with any necessary nutrients and pesticides.

The bulk storage and transport of fertilizers and agricultural products is increasingly Undertaken using woven polypropylene FIBCs (flexible intermediate bulk containers – big bags) in place of jute, paper or plastic sacks. Today, modern textile materials and constructions have helped to increase the strength, lightness and durability of traditional products, as well as open up completely new markets.

Manufacturing Processes of Agro Textiles:
Several techniques of fabric production can be used to produce agro-textiles. Each method offers specific advantages for particular product. The techniques are:

Weaving and woven products
Woven products are manufactured by using weaving machines especially Sulzer projectile weaving machines. The range of light to heavy and wide width fabric production is possible with Sulzer projectile weaving machine. The machines with weaving width of 540 cm to 846 cm are available for the production of agro-textiles. The nets with a mesh width of 1.8 mm to 40 mm can be produced. Other methods of fabric manufacturing such as air-jet and rapier weaving machines are not preferred for the manufacture of such fabrics as they do not have required weaving width.

Warp knitting technique is most widely used in comparison to weft knitting. Warp knitted protective nets are used in different sectors, which are produced on Raschel machines. Agro nets are produced in various constructions or lapping. Here, the construction or lapping is a way in which individual yarn systems are converted into fabrics.

There are many techniques to produce non-woven fabrics.

Spun bonding and needle punch techniques are mainly used for the production of non-woven agro-textiles. The spun bonded fabric has high and constant tensile strength in all directions. It has also good tearing strength.

Needle punched fabric plant bags provide advantages over conventional fired clay pots. All natural fibers offer an added advantage of that the container decomposes after being planted in the ground. Thermal Bonding, Stitch-bonded, Hydro entangled & Wet non-wovens are also used.

Agro-textiles decrease the requirement of fertilizers, water, harmful pesticides and herbicides and render a healthy farming culture and are an eco-friendly technique. They prevent the soil from drying out increase crop yield. Thermal protection textiles are treated with ultraviolet ray stabilizers & it can save up to 40% on energy in heating greenhouses. Their use prevents staining and improves uniformity of color. They increase the early maturing of crops and non seasonal plants & protect from climatic changes and its effect. Agro textiles avoid branches from breaking, increase the cleanliness of the crop, make harvesting easy & give large space. Agro textiles for its excellent environmental resistance, mechanical properties, easy process ability and durability characteristics can improve quantity, quality and safety of agricultural products.

Applications of Agro Textiles:

A. Agrotextiles for Production of Crops:
The selection of Agro-textile product is depends on crop needs. Selection of the agro textiles is also greatly influenced by the geographical location. Some of the applications of agro textiles are as follows:

Sunscreen net:
The Warp-knitted nets are used in order to protect fields and greenhouses from the intense solar radiation for healthy plant growth and good harvest. Sunscreen nets with open mesh construction are used to control sunshine and amount of shade required. These net fabrics allow the air to flow freely. So the excess heat does not built up under the screen. The percentage of shadow varies according to the density of threads. The current offer 45%, 65% & approximately 85% shadow.

Bird protection nets:
Knitted monofilament nets (Open knitted nets for crop protection) offer effective passive protection of seeds, crops and fruit against damage caused by birds and a variety of pests. Open‐mesh net fabrics are used as a means of protecting fruit plantation. The special open structure repels birds, provides minimal shading and excellent air circulation ‐ allowing plants to flourish, whilst avoiding the risk of dangerous mold developing on the fruit. These net are strong yet lightweight and protect the fruit without restricting plant growth. The use of polyethylene tape yarns or mono filament yarns makes the net extremely durable and hard-wearing.

Ground cover net:
Ground cover is an extremely versatile landscaping and horticultural fabric for long‐term weed control, moisture conservation and separation. It effectively suppresses competitive weed growth, conserves ground moisture, maintains a clean surface, protects from UV rays and creates a favorable environment for healthy plant growth. Ground covers can reduce the costs and minimizes undesirable herbicide use. It is mainly used in Borders & rockeries, nursery display areas, greenhouse floors, soft fruits beds & orchards, paved areas, horse bridleways & seed harvesting areas. 100% polypropylene is used.

Windshield /Wind protection nets/Wind-breaks:
Windshields are used in farming to protect fields of young plants, fruits, trees or the harvest from being damaged by the wind. Erecting wind-breaks at right angles protects the young seedlings and the mature plants from dying out and being broken. The nets used here reduce the effects of high winds and even help to keep out airborne sand and salt in areas close to the sea. Protecting plants from high winds also encourages plant growth and reduces the number of irrigation cycles required. It also prevents plants being cooled by wind too.

Root ball net:
It is extremely important for safe and speedy growing of young plants such that root system is not damaged when they are dug up, transported or replanted. Normally the root balls are wrapped in cloth. Elastic net tubes are alternative to this. When the plants are transplanted, the nets on the outside do not have to be removed since the roots can protrude through the nets.

Monofil nets:
Tough, knitted Monofil, nets for windbreak fences and shading/ privacy screens, A suitable windbreak, set at a right‐angle to the prevailing wind, will protect plants against the harmful effects of blustery weather ‐ which can break young branches, damage flowers and cause leaves to dry or tear. The nets also protect against frosts and help enhance the micro‐climate. This not only safeguards the current harvest but also benefits future crops, since the woody part of the plant are protected too.

B. Agro Textiles for Horticulture and Floriculture:
Application of textile materials in horticulture is growing fast. Nets, non‐woven mats, movable screens for glass/poly houses, non‐woven sheets, mixed bed for mushrooms, cordage and strings are used in horticulture. Nets are also used for protection against hailstorms, intense sunrays, etc. Light resistant woven and non-woven polyester fabrics are used in the inside of green house to protect the plants from extreme hot or cold conditions. They are also used on the outside of the green houses as screen to control sun light.
