ABSTRACT
In this paper the whole list of nonwoven technologies existing in this world are summarised, Initially, web forming technologies are summarised followed by summarization of web bonding technologies. Then all the composite nonwoven technologies are summarised and then the bicomponent melt blown technology is mentioned FInally in conclusions the usefulness of the paper is stated.
