MVS (Murata Vortex Spinning)
The air vortex spinning method used by the MVS (Murata Vortex Spinning) takes drawn cotton sliver and drafts it to the desired yarn count using a four roller/apron drafting system.
The drafted fibres are then sucked into a nozzle where a high speed ‘vortex' air current wraps the fibres around the outside of a hollow stationary spindle.
MVS fabrics are generally highly resistant to abrasive damage and pill formation, and consequently retain a fresh appearance even after many launderings.
Less Hairiness & Clear Appearance
Thanks to the air-combed and air-singed effect, MVS has the lowest hairiness of any spun yarn.
This characteristic leads to excellent resistance to pilling and abrasion of garments, reduction of troubles at post-spinning processes, and durability despite repeated laundering. You will notice drastic reduction of lint shedding.
Resistance to Pilling
MVS is the answer to pilling problems, giving the superior structural features of low hairiness and excellent resistance to pilling at the garment stage. Yesterday, pilling was left as an unsettled matter for the regular wear market. Today, MVS offer the solution, and possibilities in creating new markets.

Wash & Wear Resistance
Minimized Lint Shedding & Super Durability
Vortex piles are free from lint shedding after repeated washing and drying. On the other hand, after five sessions in the home laundry for OE-Rotor piles, lint was washed out and fiber dust accumulated on the drain filter. Generally speaking, fabric softness and durability are opposing features. To unify the discrepancy, the twist structure must be set at the desired level. Conventionally, twist number is adjusted for applications. In the MVS, instead of twist number, bulkiness of the yarn is the main parameter of softness. Bulky yarn tends naturally to loose durability. However, thanks to the yarn structure, MVS maintain superior durability.
Stability against Deformation
Low Twisting Torque & Low Shrinkage
Generally, knitting wear of MVS has a preferable stability against deformations. The deformation tendency may be regarded as drawback of fabric characteristics, especially in recovery from deformation. Twisted yarn establishes the three-dimensional structure of fabric.
This tendency gives a better recoverability from deformation, and soft touch. MVS has also real twist structure. All fibers are oriented in the same direction but not to the same degree, so knitting wear tends in two-dimensional structures and gives more resistance to deformation.
Moisture Absorption & Quick Drying
Why is MVS ideal for regular and sports wear? Because they absorb moisture well and dry quickly, giving a comfortable feeling during sports and outdoor activities, and while sleeping on humid summer nights. Highly twisted yarns aim to give a cool and dry touch. Unfortunately, they have a critical drawback, in that the yarn can not absorb moisture or wick it away.
MVS, by their unique yarn structure, achieve the co-existence of yarn tightness and the features of moisture absorption and quick drying. This makes them ideal for regular and sports wear.
