Nonwoven fabrics begin with either synthetic or natural fibers in a staple fiber form or as continuous filaments.  Staple fibers are short, chopped fibers that can be blended with other fiber types.  Both staple and continuous filament fibers can be made with varying diameters.  Typically a fiber's diameter is measured in D.P.F. (denier per filament).

Fibers can be made from a single synthetic polymer, but they can also be combined to form a bi-component (sheath-core) or bi-constituent (side-by-side) fiber.  Even though round is the most common fibrous shape, fibers can be extruded in different cross-section shapes depending on desired functionality.

Spunbond (or spunlaid)

The initial stages of the spunbond process are similar to the principles of a spaghetti press or meat grinder where a lump of dough or meat is pressed through a grate.  The resulting resin is then melted and fed through a spinneret to create string-like filaments.

These strings are drawn down through an attenuation process to alter the denier (diameter) and jetted onto a moving conveyor belt to form the web.  There are various methods of attenuation and jetting which dictate the type of spunlaid fabric manufactured.  Meltblown is another type of spunlaid with extremely fine denier fibers.
