The three industry partners Kelheim Fibres, Linz Textil and DyStar have collaborately developed and produced Proshade, an innovative new viscose melange yarn.

Compared to the ordinary melange yarn, which 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.

The two companies, Kelheim Fibres and DyStar, will be presenting this innovative solution at ITMA 2015 trade fair for textile machinery that takes place from 12-19 November in Milan.

Special properties

Due to its permanent cationic charge this speciality fibre has a significantly higher dye absorption capacity than standard viscose fibres, according to the manufacturers.

The difference in intensity and speed of the dye pick-up of the viscose fibres spun into Danufil ProShade is said to allow 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, companies report. A selected range of Levafix and Remazol dyes is said to allow a salt-free dyeing process. Due to shorter dyeing cycles it is possible to save up to 30% in terms of water and energy, whilst not compromising the productivity.

Benefits

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, Kelheim Fibres reports. DyStar also offers comprehensive customer support – including support in developing dye recipes to ensure optimum results.

There are also benefits in terms of logistics and warehousing, according to the company. Danufil ProShade can replace a stock of differently dyed yarns or fabrics and so reduce 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 to allow a fast and flexible reaction to orders, as well as production on demand – even of small melange lots.

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. The three partners are currently testing more fibre blends and dyeing possibilities.
