Great Lakes Filters provides many styles and corresponding ranges of polyester, polypropylene, and Bico spunbond fabrics for a variety of end uses and applications. They are formed by melting and extruding the polymer through spinnerets, and the extruded filaments are drawn by air onto a conveyor to form a web by subjecting the fibers to heat and pressure, bonding at the fiber cross-over points.
Spunbond polyester fabrics commonly have more uniform properties than other structures of non-wovens. We can supply them in widths ranging from 1” to 204” with basis weights ranging from 12 gsm to over 300 gsm, and they are produced using medium to coarse dpf continuous filament fibers. Polyester is a good choice when thermal properties, moldability, strength, permeability, UV, and high dimensional stability are needed in the application process.
Spunbond polypropylene fabrics are uniform and dimensionally stable, and typically made with fine to medium dpf continuous filament fibers. These fabrics are supplied in widths ranging from 1” to 200” with basis weights ranging from 8 gsm to over 200 gsm, and require additives for UV and heat stability. They also tend to be more economical than other fabrics.
Spunbond Bico fabrics are produced using different ratios of filament fibers. These are supplied in widths ranging from 1” to 165” with basis weights of 20 gsm to 250 gsm. Common characteristics of this fabric include good weldability, moldability, stability, permeability, and fiber distribution.
