Danufil® Proshade® - Melange 2.0

Danufil® Proshade® is the name of an innovative new viscose melange yarn resulting from a development cooperation between the three industry partners Kelheim Fibres, Linz Textil and DyStar.

What’s new about Danufil® ProShade®? 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 in the process.

This is made possible by the particular properties of Kelheim’s Danufil® Deep Dye fibre: Due to its permanent cationic charge this speciality fibre has a significantly higher dye absorption capacity than standard viscose fibres. 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.

Thus, Danufil® ProShade® melange yarn offers clear benefits for the dyeing process: a selected range of Levafix® and Remazol® dyes allows a salt-free dyeing process. Due to shorter dyeing cycles it is possible to save up to 30% in terms of water and energy, which is a clear advantage for the environment. At the same time productivity increases –a time saving of up to 40% speaks for itself! Excellent reproducibility, levelness as well as a high level of light fastness and fastness to washing have 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.

More benefits are obvious in terms of logistics and warehousing: Danufil® ProShade® can replace a stock of differently dyed yarns or fabrics and so reduces significantly the amount of capital required. The subsequent dyeing can be done in thousands of different melange tones according to the customer’s specific needs and so allows a fast and flexible reaction to orders as well as production on demand – even of small melange lots.

Kelheim Fibres‘ expertise in the manufacturing of viscose speciality fibres, know-how and innovative spinning technology from Linz Textil and finally high-quality dyes and customer-oriented support from DyStar are combined in an innovative product which delivers significantly more efficiency and a better ecological performance in melange production.

Danufil® ProShade® is exclusively available from Linz Textil. Danufil® ProShade® is available in all yarn technologies and is a registered brand name of Linz Textil GesmbH. The three partners are currently testing more fibre blends and dyeing possibilities.

Kelheim Fibres and DyStar will be presenting this innovative solution at ITMA in Milan.
