The well known and proven technology of Fourné melt spintesters is especially suitable for:
|Testing of spinnability of polymer materials (chips or powder)|
|Production of smallest amounts of filament yarn or fibers|
|Production of material samples|
|Development of new fiber materials for special applications|
For these processes all the advantages of a Fourné melt spintester become apparent, i.e.:
|Lowest raw material demand and minimized throughput with optimum homogeneity of the melt in Fourné spinning extruders|
|Retrofitting of side stream units for liquid or melted additives|
|Extendable for all kinds of bi- and multi-component fiber production|
|Optional equipment available for production of hollow fibers|
|Reproduction of the production process in a small space|
|One-man operation possible|
Laboratory spintesters allow tests with material throughputs between 300 g and 5 kg per hour. With pilot spinning plants throughputs from
4 kg to 50 kg per hour are possible, depending on the specification.
The standard spinning systems are designed for polymers with spinning temperatures up to approx. 350 °C, suitable for e.g. PET, PA, PP, PE.
Optionally Fourné can offer a high temperature system for spinning temperatures up to 500 °C, so that spinning of polymers like PEEK or PPS become possible.
Depending on the specification titers of 22 – 240 or 100 to 500 dtex are possible for multifilaments, comprising a capillary fineness of 0,5 to 20 dtex. For monofilaments diameters of approx. 0,01 to 0,15 mm are practicable.
Fourné melt spinning plants can be designed for different spinning processes:
|POY spinning of textile yarns|
|FDY spinning of textile yarns|
|MOY spinning of textile yarns|
|UDY spinning of textile yarns|
|BCF spinning of carpet yarns|
|Production of technical and industrial yarns|
|Bicomponent yarns and fibers|
|Spinning of hollow fibers|
|Spunbond and melt blown non-wovens|
|Spundied filament yarns and fibers with masterbatch dosing systems|
With universal spintesters it is possible to run several of these processes on a single plant.
