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 freeFabrics Non-Wovenstructure
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, suitablefor certain use. Their various properties are combined together in order to create the requiredfunctionalities. • The modern nonwoven technologies are permits to simulaterequired structures and properties as per market need. Some of the commercially available products are listedbelow:

Agriculture &Horticulture Nonwovens are used effectively for optimizing the productivity ofcrops, gardens andgreenhouses. In horticultural applications, nonwovens protect the plants against temperature extremes by day and by night, thus creating the foundation for earlier harvests with excellentresults.

GEOTEXTILES Nonwoven Geotextiles are thicker and made either from short and continuous filaments, carded or laid in even patterns and then mechanically (needle punched) or thermallybonded.
Benefits of using Nonwovenin GeoTextiles • Cheap and easy tomanufacture. • Superior chemical resistance in eventhe • aggressive environmentapplication. • Highly porousstructure • Staple fibers needle punched together toform fabric capable of withstanding construction installationstresses.
Nonwoven applicationsin CONSTRUCTION • Soundinsulation • Anti-radiation-type construction textiles will be very important in thefuture. • Foil, a special film, combined with materials such as foam thermal insulationproducts • Resistance to hydrolysis with water, which is important in areas where contactis • inevitable PU-ether-based chemical applied to the use oftextiles. • Breathable, wind-and rain-proof lighthouses.
