In the global spinning sector, products made by ring spinning accounts for more than 93% of the total volume, whereas rotor spinning accounts for 3%-5% (25% in Europe) of the total number of spindles for ring spinning. In the meantime, about a quarter of the total length of yarns and 40% of total weight of yarn made in the world are rotor spun.
Modern ring spinning machinery offers a higher level of automation and improved quality, and it takes fewer and fewer staff to operate at the production floor. Ring spinning thus is currently the most extensively used in the field of spinning machinery for its good flexibility and reliability in application, machinery builders continue to enhance and innovate in this type of spinning machinery.
Technological improvement towards energy-savings
Advanced ring spinning machinery in the international market can offer over 1,600 spindles per machine, reducing the average cost in producing a given volume of output. Energy efficiency, however, is one of the key issues in this kind of machine, and new models consume less energy, which becomes a heavier burden as energy and oil prices have increased sharply in recent years.
Ring spinning machine consumes most of the energy, between 40%-60% of the total mill consumption and a substantial part of this is spent for driving the spindles. Quality spindle types can help reduce energy consumption.
Other ways of spinning include the use of rotor spinning, jet spinning, static spinning, friction spinning, parallel spinning, vortex spinning and self-twist spinning. New technologies involving Siro spinning and compact spinning are also developed and improved in these years.
Quality yarns made by compact and vortex spinning
More combed cotton yarns in the medium and fine count range are produced by the compact spinning method for improved yarn quality.
The technology is able to better utilize the fiber substance and reduce yarn hairiness, thereby minimizing extra processes and save costs in downstream processing stages. It also provides greater design scope in the spinning mill.
The low level of hairiness and the smooth structure of compact yarns can be observed in the end product such as high-quality business shirts with a higher luster or a more marked color. Zinser 351 C³ compact spinning machine provided by Oerlikon Schlafhorst, for instance, works in high production speeds while ensuring process reliability, especially with regard to fine compact yarns.
Spinning technologies developed by Murata of Japan also aims to offer high-quality yarns. Its vortex spinning machine is suitable for producing functional and fashionable yarns with consistent quality at a competitive price. The Vortex 861 system produces yarn called Vortex, a quality yarn with high function and fashion applicability for regular wear and casual fashion.
Long fibers are made as the core and short fibers are spun in the outer layer through the process of vortex spinning. The company says that such unique yarn structure delivers multiple features: less hairiness, resistance to pilling and abrasion, moisture absorption and wash resistance, as well as stability against deformation.
According to Murata, it is possible to greatly reduce running costs and expenses required for labor, power and maintenance with the vortex spinning technology by integrating roving, spinning and winding processes.
In addition to suppliers from Germany, Italy, France, Switzerland, Spain, Japan and other countries, there emerged a number of Chinese spinning machinery builders, such as Pacific Mechatronic Group.
