This density was defined according to the `Equivalent Pore Model' and was experimentally determined by an optical method. The method permits a description of the anisotropy and the main direction of the fibrous network on both faces of the webs. Despite the lesser thickness, the spunbonded nonwovens presented a different organization of the filaments on the two faces. The conveyor face was more anisotropic than the upper one. The filament lay down process in the Perfobond technology was analyzed. The combined action of the velocities of the filaments, of the belt and of the air suction, influenced the structure, causing two important effects: a rotation of the filaments and a shear stress. The air suction velocity appears to be the most important variable, which controls the action of the belt. <\/jats:p>","DOI":"10.1177\/0040517507073427","type":"journal-article","created":{"date-parts":[[2007,6,11]],"date-time":"2007-06-11T11:04:26Z","timestamp":1181559866000},"page":"805-812","source":"Crossref","is-referenced-by-count":8,"title":["Relationship between Fibrous Structure and Spunbond Process"],"prefix":"10.1177","volume":"76","author":[{"given":"Rita","family":"Salvado","sequence":"first","affiliation":[{"name":"Research Unit of Textile and Paper Materials, University of Beira                         Interior, 6201-001 Covilh\u00e3, Portugal,"}]},{"given":"Jacques","family":"Silvy","sequence":"additional","affiliation":[{"name":"Research Unit of Textile and Paper Materials, University of Beira                         Interior, 6201-001 Covilh\u00e3, Portugal"}]},{"given":"Jean-Yves","family":"Dr\u00e9an","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique et M\u00e9canique Textiles, UMR 7189                         CNRS-UHA, ENSISA, F-68093 Mulhouse, Cedex, France"}]}],"member":"179","published-online":{"date-parts":[[2006,11,1]]},"reference":[{"volume-title":"Relationship between Spunbond Process, Structure and Properties of Nonwovens for Hygiene Applications","year":"2002","author":"Salvado, R.","key":"atypb1"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1080\/00405007608630170"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1080\/00405007608630171"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1080\/00405007608630172"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1177\/004051750107100607"},{"volume-title":"Porous Media: Geometry and Transports","year":"1992","author":"Adler, P.M.","key":"atypb6"},{"issue":"2","key":"atypb7","first-page":"14","volume":"5","author":"Huang, X.C.","year":"1993","journal-title":"INDA J.
