Role of Basis Weight, Fiber Diameter and Solidity on the Properties of Melt Blown Webs, 1993 Nonwovens Conference Proceedings
R. E. Gahan
The melt blown process has the capabilities to produce webs which have a range of basis weight, fiber diameter and web solidity. These characteristics are set by the manipulation of process variables. Melt blown webs, as well as any other type of web, have many attributes needed for filtration media. These attributes include media thickness, air permeability or resistance to passage, filtration efficiency, pore size and web strength.
Through the use of regression analysis on sets of trial data, it is shown that the characteristics of the web are directly related to the basis weight, fiber diameter and solidity. Regression analysis is conducted on melt blown webs made from polypropylene, polyester and Nylon.
Predictions of fabric properties can be made based on the manipulation of the three variables, without concern for machine settings.
