Abstract
A single-ply warp knitted fabric webbing with at least one sealed selvage edge is provided. The fabric is knit with a sheathed, bi-component warp (longitudinally extending) yarn positioned at an edge of the fabric and includes a sheath formed from a low melting point polyester and a core formed of a higher melting point polyester. A fabric is formed that has superior edge stabilization at lower amperage and air pressure manufacturing values than those exhibited by yarns coated with EVA, PVC, and TPO while simultaneously possessing abrasion and cut resistance which meet or exceed current regulatory requirements.
Claims20
A fabric webbing comprising a plurality of warp strands oriented generally perpendicular to a plurality of weft strands, at least one warp strand formed from at least one yarn including a core of polyester defining a first melting point and a sheath surrounding the core formed from polyester defining a second melting point, whereby the first melting point is greater than the second melting point, and whereby the at least one warp strand is positioned in a sealed selvage edge of the fabric webbing.
A fabric webbing comprising a plurality of longitudinally oriented warp strands knitted generally perpendicular to a plurality of laterally oriented weft strands, at least one of the warp strands formed from at least one hundred (100) bi-component filaments, each filament including a core of polyester defining a first melting point and a sheath surrounding the core formed from polyester defining a second melting point, whereby the first melting point is greater than the second melting point, and whereby the at least one warp strand is positioned at a selvage edge of the fabric webbing which is ultrasonically sealed.
