A seminar on

AGRO TEXTILE an over view

Submitted by

AGRO TEXTILES• Special textiles that are manufactured for

agricultural applications• These textile structures are used as controlling

environment for plants/animals in applications like– Agriculture– Horticulture – Animal husbandry

Benefits Of Agro textile Products

Used in Protected Cultivation For Indian Agriculturists for improved Productivity & Quality Of Produce and lower Cost Of Production

on the basis of fabrics production technique:•Woven

•Non woven•Knitted

on the basis of areas application:

a) Agro textiles for crop production (agriculture)

b) Agro textiles for horticulture (garden cultivation), floriculture and forestry

c) Agro textiles for animal husbandry and aqua culture.

d) Agro textiles for agro packaging related applications.

• 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

• In India, presently Agricultural Activities are carried out under Natural Conditions of Temperature and Humidity

FACTORS INFLUENCING AGRICULTURAL ACTIVITIES

NEED OF AGRO TEXTILES:•They prevent the soil from drying out and increase crop yield.•They improve product quality.•Agro textiles protect farmers from harmful pesticides.• Can save up to 40% energy in heating • Greenhouses.

PROPERTIES REQUIRED FOR AGRO TEXTIES:Performance ratio.Ease of transport.Space saving storage.Long service life.Resistance to solar radiation. Resistance to ultraviolet radiation.Biodegradability.High potential to retain water.Protection property.

FIBERS OF AGRO TEXTILES:Among synthetic fibers, polyolefin fibers are

extensively used.synthetic fibers are widely used in agro tech sector

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.

When we consider jute, wool, coir, sisal, flax and hemp fibers are the representative of natural fibers. Due to their high strength, durability and other suitable properties of agricultural applications.

NATURAL FIBERS AND THEIR APPLICATIONS IN AGRO TEXTILES:

The following are the some of the natural fibers:JuteWoolCoir

JUTEJute is a natural fiber popularly known as the golden

fiber.It is one of the cheapest and the strongest of all natural

fibers and considered as fiber of the future.Jute is second only to cotton in world's production of

textile fibers.The intrinsic properties of jute have made it possible

to develop different types of agro textiles suitable for specific applications.

USE OF JUTE IN AGRO TEXTILES: Jute agro textile is a kind of natural technical

textile.usually either in woven or nonwoven form,

made from 100% natural eco-friendly.bats fiber of jute plant used on soil To achieve higher agricultural productivity by

improving agronomical characteristics of soil and by reducing growth of unwanted vegetation.

Wool: Wool fibers are traditional raw materials for

textiles.According to the fiber diameter, they are

designated to the clothing and interior textile industry. Technical textile is the field in which, wool has

made significant gains in recent years, building up on its various special characteristics.

A major advantage of using wool for technical purposes is that the fiber diameter plays a minor role here, and this allows also cheap wool.

USES OF WOOL IN AGRO TEXXTILES: Wool has better insulation properties under

moist condition than poly propylene and can prevent seedling damage from ground frost thus enabling earlier sowing and a longer growing season.

The wool keeps the soil temperature constant

when we compared with black plastic, does not give a wind tunnel effect, which dries out the soil.

COIR•Coir is a biodegradable organic fiber.• It is much hardest among other natural fiber.• It has much more advantageous in different application for agricultural textiles.• Coir is used commercially for the manufacture of wide range of products for various end-use applications.

Use of Coir in Agricultural Textiles:•Coir being having the strong characteristics of retention of moisture

is preferred for the agricultural applications. •It is naturally resistant to rot, moulds and moisture. •To suit specific applications, the coir fiber can be used as thus or by

making a suitable product, which adapts the specific needs.• Coir can be converted to coir yarn and then to woven mesh matting,

which is used mainly controlling soil erosion and conditioning the soil.• One more conversion of coir is to coir nonwoven, which is also

used for controlling erosion.•The coir fiber is also used for coco logs and coco beds for shore

protection and stream banks.

Recent Trend of Developments in Agro textiles:

• Polymer fibre balls as substitute for soil

• Screening fabrics for sunlight management

• Knitted net hose for water transportation

• Superabsorbent polymer fibre mats for water management in horticulture applications

• Use of water retention nets coated with Superabsorbent polymer resin

• Composites of hemp or polypropylene for reducing soil pollutants
