In VORTEX spinning, the tip of the fiber is focused to the center of the yarn by the vortex of compressed air so that the center of the yarn is always made straight without twisted. The other tip forms the outer layer that twines another fiber.
An entirely new technology “to spin yarn with the vortex flow of compressed air” created VORTEX, a quite new type of yarn.
This technology is not applied to any limited material, but produces the VORTEX yarn with a unique structure through VORTEX spinning regardless of materials.

In VORTEX spinning, each fiber is spun toward the center of the yarn and wrapped by other fibers. Therefore, fiber is firmly kept in internal layers of the yarn to prevent fiber from sliding. This process produces “spun yarn with the least hairiness.“
VORTEX has many characteristics with a rich combination of functional and fashionable features. This unique spinning technology makes many globally famous apparel companies able to develop high-value-added products with VORTEX.

*In case of Z twist yarn.
The figure on the right shows vertically the tightness of twisting, and Z-twist and S-twist indicate the directions of twisting centering on “0.”
The horizontal axis in the graph shows the distance from the center in a cross section of the yarn.
The image chart of each type of yarn shows the yarn-twisting structure seen from the side.
The center of the yarn is not twisted. Twisting is given toward the outer side of the yarn, twisting at the center of the yarn is loose, while the outer side is fully twisted.
There is no non-twisted section, twists of a certain level are given to the entire yarn from the center to the surface of the yarn. The yarn thickness is uneven. Twisting is concentrated at the thinner sections, while twisting is loose at the thicker sections and hairiness tends to come out.
All fibers are twisted from the center to the outer side.
For fibers near the surface of the yarn, twisting is uneven, and sometimes, twisting is made in the opposite direction from around the center.
