The proven series of jet cores in hardened steel, especially designed for air texturing of glass-filament yarns.
Air texturing uses air to intermingle the individual glass filaments of a multifilament yarn. This provides the yarn with greater volume. In addition to this structural change, multiple yarns with different features can also be blended at the same time. The end products can be used for both thermal and acoustic insulation.
