Nonwovens are broadly defined as sheets or web-like structures in which fibers or filaments (and through perforated films) are entangled together mechanically, thermally or chemically. They are flat, porous sheets made directly from individual fibers or molten plastic or plastic films. They are not made by weaving or knitting, nor do they require the conversion of fibers into yarn.
Spunlace non-woven fabric
Spunlace nonwovens are made by the impact of high pressure water jets on the surface of the fabric on a fast moving conveyor belt
Chemically bonded nonwovens are made by applying a binder (resin or latex) to the surface of the web
Thermal bonding nonwoven
Thermal bonding is the primary agent used in this type of nonwoven to bond the webs together.
Meltblown non-woven fabric
Meltblown nonwovens are produced by extruding molten polymer fibers through a spinning mesh or die consisting of up to 40 holes per inch
