FACTSHEETPolyJet-SP-2-FJ.Air interlacing for the filament spinning plant

English

The PolyJet-SP-2-FJ enables optimum interlacing performance and is versat-ile thanks to the well-established PolyJet holder. Replacing the jet packsmakes it easy to meet a wide range of yarn quality requirements. The yarnguides can be combined to meet virtually all customer requirements. ThePolyJet-SP-2-FJ is ideal for cost-optimised pre-interlacing or interlacing POYyarns.

PolyJet-SP-2-FJ

Air interlacingIn air interlacing, an air blast is used to mechanically intermingleindividual yarn filaments together. The resulting interlacing knotsprovide the required yarn compactness. This allows higher pro-cessing speeds, resulting in improved package build and a re-duced number of filament and yarn breaks during subsequentprocesses.
