Agro Textiles…..?

• Horticulture

• Farming

• Agricultural activities

• Benefits…..

• Enhanced quality,

• Higher yields

• Fewer damages

• Bearable losses.


Agro textiles - Fibers Used: There is use of synthetics as well as natural fibers in agro

textiles. Fibers used in agro textiles are as follows

• Nylon

• Polyester

• Polyethylene

• Polyolefin

• Polypropylene

• Jute

• Wool

Polyolefin is extensively used where as among natural jute and wool is

used it not only serve the purpose but also after some year it degrades

and act as the natural fertilizer.


Property Requirement of Agrotextiles • Weather resistance- It must work effectively in cold as well as hot

climatic conditions.

• Resistance to microorganisms-it must resistant to microorganism to

protect the living being.

• Stable construction- the construction must be such that it must be

stable for any application.

• Lightweight- the weight of the fabric should be such that it will bare

by the plant.


Applications….. 1. Hail protection: Hail protection fabrics helps shield vines from the

fruit damage and defoliation associated with hail yet still lets through plenty of sunlight.

Constructional Details:

Fibre : UV stabilized Polyethylene

Diameter of Monofilament : 0.25 to 0.3 mm

Mesh Width : 10 x 4 mm

Weave : Leno

Knitted Design : Raschel Warp diamond design

Properties:

Long lasting, tear resistant, rip resistant.

High ultraviolet stabilization for long life

Service life: 15-20 years


Wind protection Fabrics: Wind Break Fabrics protect crops from wind and, in some cases, orchard temperatures can be increased by reducing wind speed.

Construction Details:

UV stabilized fabric from UV stabilized polyethylene monofilaments both woven and knitted form.

Properties:

Strong, long lasting.

UV resistance

High tear resistance.


Shade fabric absorbing 90% of sunlight.

It is made from 100% polypropylene monofilament strands.

It is UV stabilized to hold up under the most extreme solar conditions.

It can be used for a variety of applications: wind and privacy screen, shading for sports

and recreation.

Knitted Sunshade cloth is made from 100% UV stabilized polyethylene.

Its unique lock stitch construction allows customers the ability to cut the fabric with

scissors without further unraveling.


Shade Fabrics / shade nets:

Insect Repellent Fabrics: • Various pests like Locust, Whitefly, scale insects attack some ornamental

plants and vegetables frequently. The fabrics of such kind are stretched

across the open-air plantations so that the pests can no longer get to the

plants and also the climate will not be disturbed in any way.

• Constructional Details:

• Weave : Linen

• Material: Polyethylene monofilament yarns

• Yarn Diameter : 0.25 mm

• Cloth Density : 24 epcm x 11 ppcm


Harvesting aids: • Harvesting nets are used to collect the fruits falling from a tree.

• Control cost of cultivation by eliminating additional labor utilized for harvesting.

• Harvesting nets are predominantly grip structures which can be developed using

warp knitting technology.

• Temperature Control fabric is a nonwoven, spun bonded polyester fabric designed to

protect crops from cold, frost, insects and a variety of adverse environmental factors.

• Temperature Control fabric helps captures heat on sunny days and retains heat

radiating from the ground at night.

• This aids in protecting sensitive ornamentals, nursery stock and foliage 24 hours a

day.
