Abstract
Nonwoven fabrics provide a large variety of applications such as absorbents, insulators, separators, barriers, coverstocks, and filters, etc. The importance of fabric properties cannot be overemphasized in determining their applications. Three independent fabric parameters, i.e., fiber diameter, packing density and basis weight, are determined by controlling the nonwoven processing conditions. Other fabric properties such as pore size and performance properties such as absorbency, fluid permeability, filtration efficiency and hydro-head pressure, etc. are dependent properties on the independent parameters. This paper describes the theoretical derivation of the fabric dependent properties upon their independent parameters. The experimental results are compared with the theoretical data. The theoretical design of the fabrics for desired properties is discussed.
