This thread has a highly hollow structure to trap a large amount of air in the fiber itself by virtue of its large hollow space. The hollowness has been created to the extreme so that it can hold a large amount of air to make it a light weight and comfortable polyester material.

CALCULO™ is a polyester fiber that is not only sweat-absorbent and quick drying but also features good washing resistance due to hydrophilic treatment.
Textured yarn of a random cross-sectional shape never seen before has been greatly modified using our own special polyester textured technique.
This highly functional fiber has also a lightweight feel and is dry to the touch.

ECOPET™ is polyester products(fibers, textiles, garments, and goods) made from recycled sources: various types of polyester waste, through the mechanical or chemical recycle process. It enables the effective use of the limited natural resources.

The surface area of textile made by ultra-fine polyester fiber could be tens of times greater than conventional fibers. This enhances  functions of non-slip, wiping performance, thermal barrier and anti-transparent. The texture feels soft to the skin, and reduces irritation drastically.

This polyester fiber features a highly-deformed cross-section with a variety of characteristics that include excellent perspiration absorption and quick-drying properties, light weight, heat insulation, and bulkiness.

OCTAIR™is an innovative fibers technology that elevate modern living and adapt to ever-changing lifestyles.
