Two-bar warp knitted structures are grouped by cluster analysis of mechanical and physical properties, and the resulting classified groups show distinctive characteristics. The first group represents highly smooth, full and soft properties compared with other groups, and the characteristics of the second group are less smooth, full and soft. The fabrics of the third group are very stiff and smooth, and those of the last group are the least stiff, smooth, full, and soft. By analyzing the structures within and between groups, the structural parameters affecting the overall properties of warp knitted fabrics are deter mined. The results show that the formalized factors affecting the characteristics of warp knitted fabrics are the run-in ratio, pillar-lapping movement, direction of mutual guide bar movement with parallel or counter lapping, and closed or open lap type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
