Pore Characteristic Determination with Mercury Porosimetry in Polyester Staple Yarns

摘要: There are several methods of testing porosity and relevant quantities such as pore size, size distribution, diameter etc. The intra-yarn polyester staple yarns with different cross-section shapes has been studied in this paper using mercury porosimetry, a technique which is wide-spread the industry we have now extended by us to textile technology. This method provided distribution yarn bundles revealed two readily recognizable one more specific radius per type. results turned out be almost same for each case, although composed cruciform fibers showed most largest pores. measurement curves could analyzed help theoretical considerations. theoretically fitted separated three functions that belong characteristic radii made it possible study them one. way applicability porosimetry determining fibrous structures was proven, both practice approach.
