Abstract
Nonwoven is a textile product which is engineered in a very sophisticated way with the aid of modern technologies. Probably, these modern technologies [1] are one of most important force which brought nonwovens up to the age of technical textiles. The term ‘Nonwoven’ came in existence more than half a century ago and at that time it was regarded as the low grade cheap substitute for traditional textiles. In its early stage it was manufactured from dry laid carded webs with the help of modified textile processing machines. Europe is the place where nonwoven originated, grown and matured. Now, the whole world together is making it more and more famous and useful. EDANA (The European Disposables and Nonwovens Association) and INDA (North America’s Association of the Nonwoven Fabrics Industry) has defined nonwoven [2] very well. It can be better understood as ‘a manufactured sheet, web or batt of directionally or randomly oriented fibres, bonded by friction, and/or cohesion and/or adhesion, 50% by weight of which contains fibre having length to diameter ratio more than 300’. So, it is a textile product in sheet form, having equivalent (or better properties for some specific applications) properties as traditional fabric, manufactured directly from fibres.

Nonwovens have pores of non-uniform sizes which are uniformly distributed all over of it. This type of pore characteristics and its distribution are only possible with the nonwovens not with the other type of structures such as woven fabric, knitted fabrics etc. These characterizes of the nonwoven helps in filtration and reinforcement of civil engineering sites and constructions
