Heberlein Showing Unique Air-Saving Weaving Solution At ITMA Asia
Heberlein a supplier of air interlacing and air texturing jets has developed a unique air-saving solution for a smooth and efficient weaving process which will be displayed at ITMA Asia in Hall 8.1, Stall A-43.
According to the Swiss company, high-speed weaving and warp knitting demand yarns with smooth surfaces for efficient processing.
“Special procedures to achieve the required yarn quality include air interlacing and sizing. But sizing is less favoured, since the sizing agent has to be removed after weaving, using water and creating pollution,” Heberlien said in a press release.
Heberlein innovated a completely new air interlacing system that gives considerable economic advantages in warp preparation and the subsequent fabric production sequences.
“A process creating reliable intermingling points has several benefits, as the weaving machine no longer stops because of shedding issues with filament openings or friction from broken filaments,” it stated.
“So, the weaving process runs at higher speeds, also enabling size application to be reduced,’ the company observed.
Heberlein’s high-precision components can be used when the process needs maximum efficiency and yarn strength.
The WarpJet-KV can increase the intermingling points to 60 to 90 per metre, about triple the usual number, to suit individual requirements in the weaving process.
Common speeds from 4,500 to 5,000 metre per minute in the spinning process usually allow 15/30 neps per metre, which might be sufficient for a smooth weaving process.
However, many mills prefer to be on the safe side, especially when using yarns of ≤ 75 denier and DPF ≤ 1.0, so they opt to install the Heberlein intermingling device.
The other key aspect is the air pressure needed to guarantee an increased number of intermingling points to assure filament cohesion, especially with fine yarns.
During air interlacing, an air blast physically intermingles the individual filaments of a multi-filament yarn with one another.
Saving compressed air in the air interlacing process results in less energy costs and is proven with the Heberlein WarpJet-KV.
Tests at the same machine with 1,536 threads and using the same level of air pressure showed that compared with a standard jet, the WarpJet-KV allows savings of 307 and 491 m3/h.
Comparing the air pressure needed for the same amount of intermingling points (FP/m) the savings add up to 38 percent.
The advanced technology by Heberlein also enables the diameter of the jet’s air orifice to be smaller and requires less air while producing the same number of knots.
