Teijin Fibers has launched a cationic-dyeable polyester polymer, 'V4', which can be dyed at ambient temperature and pressure, and is believed to cater excellent fibre strength and sustainability.

The V4 series will be promoted as one of the core products of Teijin Fibers in the international market. These products, which are positioned as an 'eco colour' material, reduce environmental effect of dyeing process.

The first product in this series that is to be launched soon is Waveron V4, which is a polyester fibre with a cross section of four flat peaks. This product will witness marketing from the month of July.

Cationic-dyeable polyester fibre in the V4 series is a special sort of polyester fibre as it can be coloured with cationic dye, unlike any other ordinary polyester fibre. As these fibres need to be dyed at a high temperature and pressure, it's quite difficult to combine them with natural fibres such as wool and silk.

The tests conducted by Teijin Fibers showed that the V4 dyeing process requires around 30 percent less power and steam energy and can produce 25 percent fewer CO2 emissions compared to conventional dyeing at 130 degrees Celsius, as it can be dyed at ambient temperatures of 100 degrees Celsius or even less.
