Mikawa Textile Research Institute of Aichi Industrial Technology Institute and Taisei Shokai (Gamagoori-city) have jointly succeeded in developing the technology to dye ultrahigh molecular weight polyethylene fiber in desired colos.

The method developed by them this time is easy for dyeing companies to introduce since it does not require any special equipment besides the combination of alcohol and organic solvent soluble dyes which are used for oil-based ballpoint ink, while dyes and water are generally used for dyeing fiber.

The ultrahigh molecular weight polyethylene fiber has been quite a promising material for agriculture, forestry and fisheries, industrials and engineering and construction such as for ropes and nets because of its strength which is 4 times more than that of synthetic fiber for clothing, but applications for it had been limited, having the weak point that it stood out in surrounding areas because of its sparkling white color which could not be dyed.

Increases in use and demand for ultrahigh molecular weight polyethylene- based ropes and such are anticipated with this method developed by Mikawa Textile Research Institute.
