ABOUT VORTEX

What is VORTEX?

VORTEX is the spinning machine developed by Murata Machinery Ltd., and also the yarn made out of these machines.
VORTEX yarn has many applications and enjoys good reputation, thanks to the unique yarn characteristics.

VORTEX spinning machine

VORTEX yarn is created from new and unique spinning technology
- VORTEX air flow.

Twist structure of VORTEX yarn

Each & every fiber in VORTEX yarn tends to be in the center and wraps up to the surface by the air.
This structure leads to the fact about "least hairiness" amongst all spinning systems.
Least hairiness reduces the fluff and dust generation in next process.
Printing and dyeing also take advantage of these characteristics.

Its clear appearance symbolizes the finest characteristics of VORTEX

Pilling is a phenomenon where fibers are twisted into ball-like structures by friction between the surface of a fabric and another fabric or object. Because VORTEX has less long hairs and is naturally stable due to its structure, the fibers are secure from movement resulting in reduced pilling.

See the feature of resistance to pilling.

VORTEX yarn has less lint shedding, less fabric shrinkage, less fabric skew and less color loss caused by repeated wash and dry, when compared with the yarn by other spinning process.

Less Lint shedding

Towels made from VORTEX yarn shed less lint than towels made from Ring yarn.
Additionally, a VORTEX yarn towel maintains its bulkiness longer than that made out of Ring yarn, even after repeated washing.

VORTEX yarn has less hairiness, thanks to its unique yarn structure.
This ensures clear printing on the fabrics.

VORTEX yarn has parallel fibers in the center with lot of air pockets.
This structure leads to higher water absorption.
