High Quality Yarns with the New Geminis Twisting Machine.

Savio Machine Tessili's Geminis twisting machine is a rationalized, flexible system that responds to the demands of different spinning mills. An optimized balloon geometry, new yarn guides, and high speed bobbins contribute to an increase in productivity. The Twin Master system provides production control and detects yarn defects with a h..

Murata 'Shows Commitment' with Introductions

Murata of America Incorporated introduced the latest generations of its MVS 810 Vortex spinning machine and 21C process cone winding machine. The MVS 810 manufactures functional and fashionable yarns at high speeds and low cost. Six different setups give the machine its flexibility. The MVS spinning machine requires less labor per pound o..

Airflow Spins Yarns

W. Schlafhorst AG's staple yarn manufacturing system uses an air vortex and revolving spindle to yield fast spindle revolution without false twisting. Because the air flow acts in a twisting manner on the fibers of an untwisted sliver, the resultant yarns exhibit no reduction in yarn strength. The systems bears United States patent number..

New System Spins a Good Yarn.

Murata's vortex spinning (MVS) machine accommodates a wider variety of yarns than do open end spinning machines and manufactures yarns at rate 20 times that of ring spinning machines and three times that of open end spinning machines. The MVS machine uses a drafting roll to draft sliver to a desired yarn count. A nozzle sucks in the draft..

Innovations in Short-Staple Yarn Spinning Technology.

Two innovations in short staple yarn spinning technology provide high quality yarn at high speeds. The Murata vortex air jet spinning machine (MVS) spins carded cotton at 350 meters per minute while imparting real twist. Air combing removes a high percentage of waste in the spinning zone, reducing the waste level to 4-10 percent at spinni..

Cognetex: Nex COM4 Wool Compact Spinning Machine

Cognetex SpA and Rieter jointly developed the IDEA COM4 Wool composite spinning machine for wool fibers. The replacement of the draft cylinder with a perforated drum enables the air flow to compact the fibers directly on the draft cylinder. The IDEA CM4 Wool spinning machine is available with conventional or controlled ballon spindles. Th..

Factors Influencing the Nep and Trash Transfer from the Sliver to the Rotor Yarn.

Rotor spinning process research analyzed nep and trash transfer from the sliver to the yarn and identified factors that affected the value of the transfer coefficient that describes the nep and trash transfer in the feeding sliver to the yarn. Data from the Uster testing machine and the Advanced Fiber Information System showed that yarn l..

Influence of Short Fibre Content on Yarn Properties in View of Launching Compact Spinning in the Marekt.

Compact spinning technology reduces the spinning triangle, embeds more short fibers within the spinning triangle, improves raw material utilization, reduces fly formation, improves yarn stability, and reduces yarn hairiness. Tests evaluated conventionally and compact spun yarns from gently and conventionally carded cottons and from cotton..

Multiple Twist Spindle Doubles Production and Saves Power

A multiple twist spindle system increases production speeds by 100 percent and reduces power consumption by 25-30 percent. Unlike two for one twisting, the yarn unwinds and exits through a ceramic ring guide to descend to the outside of the supply bobbin container. The spindle consists of an inner and outer balloon that creates a yarn pat..

Strategies for Optimising Spinning Preparation Using On-Line Measuring Technology

An overview of strategies for using online measuring instruments to optimize spinning preparation focuses on the integration of online measuring instruments into the spinning preparation process and provides examples of optimization strategies. Sensors record such parameters as deviations in feed quality, machine functions, and process mo..
