High tenacity polyester yarn has a wide range of applications.

This material has revolutionised material handling equipment the most. For example this material has replaced chain/wire ropes previously used for lifting of heavy equipment. This product is known as webbing slings. The advantage of webbing slings is that its width is more than chain/wire rope which distributes the reaction force on the object being lifted thereby reducing the damages. These slings have highly reduced the damages on steel coils (as shown below)


They are also easier for handling and generally weight just 20% to 30% of a wire rope sling of equivalent capacity. They are alo cheaper than manufacturing of chain or wire ropes.

Another advantage of this material is its low elongation property. This makes it suitable for using in lifting/lashing. A webbing sling generally has an elongation as low as 3% to 7% under load. This make handling of heavy equipment/object easier for the crane operators.

The low elongation and high strength has also found an application in lashing of cars.

These orange straps that you see are sufficient to hold the car is position for its entire journey accorss the ocean. Before these belts big wooden wedges had to be nailed all accross the car to secure it. Thereby saving nature as well.

This yarn is also used to manufacture defence items like bullet proof jackets.

High tenacity (HT) polyester yarn is used where there is required high tenacity. Or where tenacity has prime role. For example Banner, Tarpaulin, Roofing, Membrane Structure, Awning, Filler Fabric, Sunshade, Outdoor Furniture, Hose, Sewing Thread, Seat Belt, Sling, Conveyor Belt Fabric, Geotextile, Rope, Tire Cord, Sail Cloth and so on.

In these all applications HT polyester yarn has been used with different denier (count) or thickness.

High tenacity polyester yarn is used for high performance applications where tenacity is the key factor. Some of the application areas are as follows:

Webbings,
Narrow fabrics,
Cordage,
Deep-sea moorings,
Ropes,
Nets,
Strapping,
Slings,
Geo-textiles,
Seat belts,
Firehose,
and certain filtration products…
