Six wide-ranging business fields
KOA Textile Industry is currently expanding its business fields centering around its six business fields;
the “Tire Cord Department”, “Filament Twisted Yarn Department”, “Spun and Twisted Yarn Department”, “Air Suspension Department”, “Lifestyle Products Department”, and “Health Food Ingredients Department”, and is continuing to create new value.
-
Tire Cord Department
This has been a core department since the company’s foundation. The company’s strength lies in the fact that the range of the warp’s twist is extremely wide, with custom made items able to be produced with a warp of 25,000-30,000 denier.
-
Filament Twisted Yarn Department(hose reinforcement textiles etc.)
Processes textile material that is “Low in ductility, high in strength” into twisted yarn “without any knots” up to a maximum wound quantity of 10KG.
-
Spun and Twisted Yarn Department
From single-thread twine to a maximum of 12 threads in one, the only company in the world that can produce folded yarn with no defects or knots, using optical sensors to eliminate flaws.
-
Air Suspension Department
Through the use of our own equipment, we supply almost 100% of all twisted yarn cord for use in domestic air suspension, and we have made good spooling quality and stability at high speeds a reality.
-
Lifestyle Products Department
In co-development with a manufacturer of compound materials, our twisted yarn is used in areas such as even more highly-adhesive dental floss, and bristles for the cutting-edge model “motor head brush” in cyclone vacuum cleaners.
-
Health Food Ingredients Department
We are engaged in the factory cultivation of a succulent plant known as the Ice Plant which uses biosynthesis to produce pinitol. This is said to work as an osmotic pressure adjusting substance to increase the metabolization of glucose.
