Rieter offers the system solution with which air-jet yarns of the highest quality can be produced economically from 100% cotton. Air-jet yarns enable products with a very high-quality character to be produced. They impress with their pleasantly soft touch, uniform surface, high resistance to pilling and washing, shape retention, and intense colors.
- Maximum raw material utilization
- Significant energy saving
- Unique soft touch of knitted fabrics
The fabrics produced from yarn spun on the air-jet spinning machine J 26 have a unique color luster. The surface is very uniform, which is primarily based on the low hairiness. This is the ideal prerequisite for printing on fabrics. The contours are extremely clear and defined. End products such as T-shirts, sweaters, and terry towels have a very high-quality character. The products also impress in daily use: High resistance to pilling and washing, maximum shape retention, and intense colors – even after many washes – ensure a long-lasting and therefore sustainable product.
The example used here is of an air-jet spinning system that produces a combed yarn with a count of Ne 30 from a medium-staple cotton. To enable a comparison to be made, the Rieter system was contrasted with a “mixed spinning mill” consisting of machines from various manufacturers. The unique yarn characteristics, such as the extremely low hairiness, can increase the yarn price. However, the case study does not take this benefit of using Rieter machines into account, and is instead based on raw material prices and yarn prices for both systems being the same.
- Raw material utilization
- Energy consumption
- Space requirement
- Personnel requirement
The J 26 can produce yarns with Z- or S-twist as required. This is beneficial in the knitting mill. 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, meaning it needs to be cleaned less often, which in turn increases machine running times.
A complete Rieter system is established on Rieter’s expertise throughout the entire spinning process: from processing raw material to yarn. Rieter offers all four end spinning processes and provides professional advice on the optimal spinning technology. Furthermore, experts provide support with yarn marketing and offer a wide range of services. The entire spinning mill is networked and controlled from a single platform with ESSENTIAL – Rieter Digital Spinning Suite. This guarantees high quality and optimal efficiency, both now and in the future.
