Structures of nonwovens are different from those of traditional textile materials. Nonwovens, using a wide variety of fibers are finding an increasing market not only in short-term use disposable fabrics, but also as upholstery and carpet linings and pads. Because of this wide range of use, nonwovens are produced in a great range of patterns by different methods of bonding. These bonding methods provide materials of varying thickness, air permeability and absorption. Fiber composition, structure and bonding materials affect nonwoven properties. These structural properties of nonwovens are better understood when microscopical techniques are used to study their nature.
