Murata Vortex Spinner MVS Technology
topic
The Murata Vortex Spinner uses a single vortex nozzle where drafted fibres enter a spiral air stream that rotates fibre tips around a hollow needle at 450 metres per minute delivery speed, forming a two-component yarn of core fibres drafted straight and surface fibres helically wrapped, with the vortex spinning principle enabling 100 percent cotton processing unlike earlier air-jet systems requiring synthetic fibre content for adequate wrapping.
Role
Extended air-vortex spinning applicability to 100 percent cotton yarn by redesigning the fibre wrapping mechanism to generate adequate surface fibre wrapping without synthetic fibre support, enabling production of cotton-rich MVS yarns with the low hairiness and good pilling resistance that match compact ring yarn performance in knitwear applications at vortex spinning production speed advantages.
