2Clothtech

• Clothing textiles segment of technical textiles comprises of all textile components used primarily in garment applications which have some specific functional applications.


3Clothtech Products

• The technical textile products covered under Clothtech are: • Shoe laces • Interlinings • Zip fasteners • Elastic narrow fabrics • Velcro • Labels • Umbrella cloth • Sewing threads


4Oekotech

• Oekotech segment of technical textiles comprises of all textile components used for environmental protection.


5Oekotech…

• Oekotech textiles segment of technical textiles is dedicated in Ecological Engineering.

• The primary segment in this is Landfill waste management.

• This refers to the use of Geosynthetic goods to safe landfills against leakage of metropolitan or harmful waste.

• Other areas include secondary protection in Chemical/Oil Industries.


6

Landfill Components

• A modern engineering landfill has the following components:• A basal lining system to prevent the contamination of soil,

and ground water by pollutants, • A capping system to seal the waste when the capacity of the

landfill is exhausted, • An impervious sealing layer which prevents the entry of

pollutants in the ground, • A leach-ate collection system for the collection and

transmission of lactates to a collection pit (cavity)


7Application Areas

• Environmental protection (land fill waste management systems)

• Waste disposal • Recycling (recycling of polymer)


8Oekotech Products

• Geogrids, which can be used to reinforce slopes beneath the waste, reinforce walls as well as to reinforce cover soils above geomembranes.

• Geonets, which can be used for in-plane drainage.• Geomembranes, which are relatively impermeable, sheets

of polymeric formulations that can be used as a barrier to liquids, gases and/or vapors; provide the critical functions of leach ate containment, protection of ground water and Landfill Gas (LFG). They are also used in landfill caps.

• Geocomposites, which consist of two or more geosynthetics, can be used for separation, filtration or drainage.


9

Oekotech Products…

• Geosynthetic clay liners (GCLs), which are composite materials consisting of Bentonite and geosynthetics that can be used as an infiltration/hydraulic barrier; they find application not only in landfills/waste management but also for mine rehabilitation, tunnels, secondary containment e.g. of petrochemicals, landscaping etc.

• Geotextiles, which can be used for filtration purpose or as cushion to protect the geomembrane from puncture.


10

General Characteristics of Oekotech Products

• Both woven and non-woven geosynthetics are used. • Geosynthetic clay liners consist of non-woven fabric layers of

180-250 GSM with an intermediate layer of Bentonite mineral (Unit Mass: 1-5 kg/sq m).

• Geotextiles used for filtration/cushion are typically high GSM (285 – 3000) non-woven fabrics.

• Some most important characteristics of HDPE geomembrane are that they are:• Chemical resistance• Low permeability • Ultraviolet resistance

• The thickness of this geomembrane is 2 mm.


11Hometech

• The Hometech segment of technical textiles comprises of the textile components used in household applications.

• These products range from blinds used in the houses to the filter products used in the vacuum cleaners.


12Raw Material

• The hometech products are made of both natural and synthetic fibres.

• For example, carpet backing cloth is made from jute as well synthetic fibres.


13Products

• The technical textile products covered under Hometech are as give below: • Fiberfil • Mattress and pillow components • Carpet backing Cloth (Jute & Synthetic) • Stuff Toys • Blinds • HVAC Filters • Filter cloth for vacuum cleaners • Nonwoven wipes • Mosquito nets • Furniture fabrics


14Indutech

• Industrial textiles includes technical textile products used in the manufacturing sector.

• The technical textile products covered under Industrial textiles are given below: • Conveyor belts (TT component) • Drive belts (TT component) • Cigarette filter rods • Decatising cloth • Bolting cloth


15Indutech

The technical textile products covered under Industrial textiles (cont…)• AGM glass battery separators • Coated abrasives (TT component) • Ropes & cordages • Composites (technical textiles component) • Printed circuit boards (TT component) • Computer printer ribbon • Paper making fabrics • Filtration Products • Industrial Brushes


16Sporttech

• Sprots textiles includes technical textile products used for sports purposes.

• Technology is developed in the manufacturing of fabric used in sports purpose to ensure incorporation of special characteristics demanded by the athletics & the leisure activities for their better performance in the sports.


17Functions

Keeping skin dry by moisture managing:

By using special chemicals & by changing the cross sections of the fiber or filaments fabrics are made highly effecting in moisture management & thus they can wick the moisture as known as sweat away from the body & keeps body dry.


18Functions…

Anti-static performances:

Sports textiles fabrics have a very high electrical conductivity, so they can permit the effectual dissipation of electrical charge.

Thermodynamic:

As this sports fabric has a special property well known as heat conductivity make possible to feel the user cooler in summer & warmer in winter.


19Functions…

Antimicrobial performances:

Keeping a normal level of bacteria on the skin offers a high level of comfort and personal hygiene, especially during athletic activities.

Ultraviolet protection:

Sports textiles fabrics remove UVA and UVB rays that are dangerous to the skin, and guarantees an improved level of defense compared to the majority general natural and man-made fibers.
