Interlacing Jets for IDY spinning process

The industrial yarn draw spinning process is probably the most challenging fibre production amongst flat filament yarn manufacturing. High tenacities and extreme good stabilities are required through a wide range of yarn counts.

The various characteristics of IDY yarns like HT (High Tenacity), HMLS (High Modulus Low Shrinkage), LS (Low Shrinkage) as well as SLS (Super Low Shrinkage) are mainly used in fabrics for the automotive industry, tirecord, airbags, seatbelts etc. But also in home textiles such as sun-blinds, marquees etc. and in nautic textiles as canvas, ropes etc. IDY filament yarns are most suitable.

SPI technology

The SPI jet has been developed for high performance interlacing applications of IDY filament yarns made of polyester, polyamide as well as polypropylene.

The easy quick exchange system of the jet inserts allows a simple and safe maintenance.

The sophisticated geometry and surface character within the interlacing zone guarantee an excellent interlacing performance concerning the high requirement of the composed knot regularity.

SPS interlacing jets

SPS jet

The SPS jet is made for interlacing applications of all kind of IDY filament yarns in spin-draw processes.

Due to the advanced geometry within the interlacing zone and the unique yarn guiding system, the SPS jet is most suitable for sensitive yarn applications such as SLS-, airbag- as well as seat belt yarns, especially concerning filament deteriorations.
