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

 

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

 

What’s new about Danufil® ProShade®? While usually a mélange yarn is spun of different colored fibers, Danufil® ProShade consists of a blend of standard viscose fibers and Kelheim’s speciality viscose fiber 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 fiber. Due to its permanent cationic charge this specialty fiber has a significantly higher dye absorption capacity than standard viscose fibers. The difference in intensity and speed of the dye pick-up of the viscose fibers spun into Danufil® ProShade® allows a wide range of colors in melange dyeing of one and the same fiber material to be achieved.

 

Thus, Danufil® ProShade® mélange 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 percent 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 percent speaks for itself.

 

Excellent reproducibility, levelness as well as a high level of lightfastness 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 mélange lots.

 

Kelheim Fibres‘ expertise in the manufacturing of viscose speciality fibers, 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 that delivers significantly more efficiency and a better ecological performance in mélange production.

 

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