Kelheim develops new viscose melange yarn Danufil Proshade

In cooperation with Linz Textil and DyStar, Germany based viscose fibres producer Kelheim Fibres has developed Danufil Proshade, an innovative new viscose melange yarn.

While usually a melange yarn is spun of differently coloured fibres, Danufil ProShade consists of a blend of standard viscose fibres and Kelheim's speciality viscose fibre Danufil Deep Dye and is only dyed as needed at a later stage.

“This is made possible by the properties of Danufil Deep Dye fibre, which due to its permanent cationic charge has a significantly higher dye absorption capacity than standard viscose fibres,” a press release explained.

“The difference in intensity and speed of the dye pick-up of the viscose fibres spun into Danufil ProShade allows a wide range of colours in melange dyeing of one and the same fibre material to be achieved,” it said.

According to Kelheim, Danufil ProShade melange yarn offers clear benefits for the dyeing process, while a selected range of Levafix and Remazol dyes allow a salt-free dyeing process.

“Due to shorter dyeing cycles it is possible to save up to 30 per cent in terms of water and energy and at the same time productivity increases,” the company informed.

Kelheim further added that excellent reproducibility, levelness as well as a high level of light fastness and fastness to washing has been proven in numerous tests and commercial dyeing processes.

Furthermore, DyStar offers comprehensive customer support, including support in developing dye recipes that ensure optimum results.

“Danufil ProShade can replace a stock of differently dyed yarns or fabrics and so reduces significantly the amount of capital required,” the viscose fibre producer stated.

“The subsequent dyeing can be done in thousands of different melange tones and so allows a fast and flexible reaction to orders as well as production on demand, even of small melange lots,” it observed.

The product has been developed from Kelheim Fibres expertise in manufacturing of fibres, innovative spinning technology from Linz Textil and finally high-quality dyes and customer-oriented support from DyStar. (AR)
