Frequently asked questions
Frequently asked questions related to VORTEX are introduced.
What is VORTEX?
VORTEX is the name of a spinning machine developed and manufactured by Murata Machinery, Ltd. The yarn produced by the spinning machine is called VORTEX yarn. (Note: Although it may be called "MVS", this is an abbreviated name for the spinning machine "Murata Vortex Spinner".)
Can VORTEX yarn be produced by other spinning machines?
Although typical production methods of staple yarns are Ring spinning and Open-end spinning, VORTEX spinning is a third method developed by Murata Machinery. As VORTEX yarn is produced using a unique principle of yarn formation, it cannot be produced by other spinning machines. (For details, see the page on the principles of spinning)
What is the spinning method of VORTEX?
In both Ring spinning and open-end spinning, fibers are twisted by mechanical means in order to form a yarn. In VORTEX spinning, a vortex of compressed air having no moving parts, is used to form a yarn.
Can the number of twists of VORTEX yarn be measured and adjusted?
As fibers are not mechanically twisted in VORTEX spinning, the number of twists cannot be mechanically set. In ring spinning, the number of twists is adjusted according to the application. However, in VORTEX spinning, the strength of the compressed air vortex and the spinning speed are used for adjustment.
What kinds of fibers can be spun by a VORTEX spinning machine?
Basically, short fibers used for normal staple yarns, (2 inches (51mm) or shorter), can be spun. However, fibers with very high elongation or fibers inappropriate for a vortex of compressed air may be difficult to spin.
