Produce Innovative Yarn Economically

Efficient air-jet spinning system for 100% combed cotton

A Rieter spinning mill with the air-jet spinning machines J 26 produces unique cotton yarns extremely economically.

There is increasing demand for air-jet yarns in the textile chain. These enable very high-quality products to be produced. Rieter introduces the process with which air-jet yarns of the highest quality can be made economically from 100% cotton.

Yarns that are made of combed cotton and have been spun on a Rieter air-jet spinning system impress with their pleasant soft touch, even surface, impressive resistance to pilling and washing, shape retention, and intense colors. The spinning mill line with the productive UNIclean B 15, the innovative card C 80, the new comber E 90 and the optimized air-jet spinning machine J 26 guarantees maximum fiber utilization, low energy consumption, reduced space requirements and high productivity – and therefore the cost-effective production of these yarns.

Economic advantages

Thanks to the top-quality fiber preparation with efficient noil extraction on the comber E 90, as well as the optimal fiber guiding in the spinning unit of the air-jet spinning machine J 26, the average raw material utilization is four percentage points better than with other systems. Energy-saving elements, such as the individual drives on the spinning and winding units, enable energy savings of up to 15% throughout the entire system. With the compact draw frames, the double-sided machine concept of the J 26 and the high machine performance, a Rieter system uses significantly less space than other systems. The new card and the new comber set a very high benchmark for productivity in an air-jet spinning system for cotton. The J 26 convinces with its high efficiency and a delivery speed of 440 m/min for combed cotton yarn with a count of Ne 30.

Increase quality and efficiency

The proven air-jet spinning machine J 26 offers innovations which simplify handling and support consistent yarn quality. The spinning nozzle, the heart of the yarn formation, has a new hinged design. This enables fast and efficient operation. The newly developed suction system ensures that much less trash and fewer fibers collect at the drafting system. The yarn quality remains consistently high. Individual drives at every winding unit make it possible to produce yarn packages with different hardness. This allows soft dye packages to be produced directly on the machine, which avoids the need for time-consuming rewinding. Winding the yarn using “true anti-patterning” prevents threads in multiple successive winding layers from lying on top of each other or parallel next to each other. This is the only way to achieve perfect and even package build-up and thereby optimal unwinding behavior in the following process.

Unique advantages for downstream processing

The J 26 can produce yarns with Z- or S-twist as required. This is beneficial in knitting. By alternately feeding Z- and S-twisted yarns, the knitted surface becomes dimensionally stable and the touch becomes very soft. Even after several washing cycles, the products do not tend to be affected by spirality.

In weaving mills, the air-jet yarns convince with a very good size pick-up, which lowers the size amount and therefore reduces the costs. After weaving, the fabric is washed, whereby the cleaning of the waste water is less elaborate and thus more environmentally friendly.

The low hairiness of the J 26 yarns also reduces the fiber fly during weaving. This minimizes deposits on the weaving machine. There is less need to be cleaned, which increases machine running times.

Fabrics with high-quality character

The fabrics produced from the J 26 yarn have a unique color luster. The surface is very even, which is primarily based on the low hairiness. This is the ideal prerequisite for printing on fabrics. The contours are extremely clear and defined. Overall, end products such as T-shirts, sweaters and terry towels have a very high-quality character. The products also impress in daily use: High piling and wash resistance, maximum shape retention and intense colors – even after many washes – ensure a long-lasting and therefore sustainable product.
