FACTSHEET
KF jet insert.
Knot-free air interlacing for texturing
HEBERLEIN® KF jet insert.
Interlacing without visible interlacing knots
The KF jet insert is the optimal solution for knot-free air interlacing of DTY
yarns. Although the yarn is combined, it shows no visible interlacing knots.
Consequently, the fabric does not have any interlacing knots, either.
Knot-Free Interlacing
In knot-free interlacing, the individual filaments are easily
bundled by means of an air blast. Visible knots in the fabric are a
thing of the past. This technology is suitable for filament yarns
made of polyester.
KF jet insert
Features and Benefits
• Very gentle treatment of the yarn, especially
suited for micro-filament and polyester yarns
• The air stream ensures that the filaments are
bundled and can therefore be easily reeled off the
package
• Leaves no visible, disruptive interlacing knots
behind in the fabric

• Cost-effective
• High-quality ceramic parts
• Simple maintenance

Under standard conditions according to DIN 1343: temperature = 0 °C, pressure = 1.01325 bar, relative humidity = 0 %, 1 standard cubic metre = 1.293 kg (psi = 14.7 x bar, CFM =
0.588 x m3/h)
qvn = air consumption [m3/h], pe = overpressure [bar]. Formula applies from 0.8 bar
