Nonwoven technology Web forming The staple fibres are mixed, opened and spread into a flat web with wet, airflow or needle board, and the web is often deposited on a transverse conveyor belt. All the fibres used must have an added surface treatment at the manufacturing stage (0.4 % to 2.0 % by weight), which
