Introduction
Nonwoven Fabric is a fabric-like material made from long fibers, bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Nonwoven materials typically lack strength unless densified or reinforced by a backing.
It may also having other names such as Shaped Fabrics (or) Yarn free Fabrics
Non-Woven structure
Definition
Nonwoven stuffs are largely described as piece or web structures, bonded simultaneously by entangling fibre or filaments mechanically, thermally or chemically.
• Nonwovens are designed to offer particular characteristics, suitable for certain use. Their various properties are combined together in order to create the required functionalities.
• The modern nonwoven technologies are permits to simulate required structures and properties as per market need. Some of the commercially available products are listed below:

Classification
Nonwovens are used effectively for optimizing the productivity of crops,gardens and greenhouses.
In horticultural applications, nonwovens protect the plants against temperature extremes by day and by night, thus creating the foundation for earlier harvests with excellent results.

Nonwoven Geotextiles are thicker and made either from short and continuous filaments, carded or laid in even patterns and then mechanically (needle punched) or thermally bonded.
GEO TEXTILES
Benefits of using Nonwoven inGeoTextiles
• Cheap and easy to manufacture.
• Superior chemical resistance in even theaggressive environment application.
• Highly porous structure
• Staple fibers needle punched together to form fabric capable of withstanding construction installation stresses.
- Sound insulation
- Anti-radiation-type construction textiles will be very important in the future.
- Foil, a special film, combined with materials such as foam thermal insulation products
- Resistance to hydrolysis with water, which is important in areas where contact isinevitable PU-ether-based chemical applied to the use of textiles.
- Breathable, wind-and rain-proof light houses.
Nonwoven applications inCONSTRUCTION
Household Textiles
Nonwoven fabrics can be used in thefollowing household textile applications:
– Floor coverings
– Upholstery materials
– Webbings, etc.,
Nonwoven wall hanging
China nonwoven carpet
Automotive InteriorsFacings and structural reinforcement materials are used in a variety of different applications Includes:
Headliners Trunk liners Door trim Package trays Sun visors Seats
In Shoes
A broad spectrum of applications including:- Liners- Counter
liners- Inter-liners
and- Reinforcing
materialsMembranes and insoles ensure a healthy foot climate and a high degree of foot comfort.
Advantages of using nonwovens
• Easy to recycle and compost• Easy to convert into pads and shapes• High tear resistance
