Thies has redesigned and upgraded its soft-TRD series of dyeing systems with the aim of offering resource-saving technology with even greater energy efficiency.
According to Thies, the soft-TRD series has offered customers successful processing options for a broad range of applications.
“With the long chambers and the intensive penetration zone of the transport pipe of this series ensuring maximum qualities and reproducibility,” it said in a press release.
In the redesigned soft-TRD series of machines, high water consumption, which leads to an excessive use of chemicals, electricity and thermal energy, has been significantly reduced.
“Application engineers at Thies have succeeded in achieving liquor ratios of 1:4.5 for PES woven fabrics,” it informed.
The dyeing vessel has been redesigned so that it no longer needs to be fully flooded during processing and the fill level is freely selectable and the fluid level can be adjusted accordingly.
In partially filled systems, the temperature distribution is unfavourable as the liquid heated by the heat exchanger heats the textiles and also the dyeing vessel unevenly.
“By using an intelligent vessel wall temperature regulator, it is possible to achieve uniform and, more importantly, simultaneous heating of the product, the liquor and the vessel wall,” it added.
“This improved regulation can also help reduce the deposition of oligomers during polyester dyeing,” the German producer of dyeing technology noted.
It further added that items that are crease sensitive or have delicate surfaces can be treated gently at speeds of up to 600 m/min.
The free material flow and the low-mounted intensive penetration zone of the transport pipe allow optimum relaxation, free shrinkage and a uniform treatment of the entire fabric rope in the chamber.
The intensive penetration zone of the transport pipe has also been redesigned, avoiding excessive twisting of the rope.
An automatically adjustable vario-nozzle provides additional flexibility as numerous articles can be successfully treated.
The soft-TRD SIII is designed for operating temperatures of up to 140°C and due to the new integrated vessel pressure regulation; the use of compressed air has been significantly reduced.
The nominal load of the soft-TRD SIII is 100 kg, 150 kg and 200 kg per chamber and the modular design makes it possible to combine up to 4 chambers.
Individual chambers can be locked off if required, which allows the processing of custom batch sizes.
The drive reel has a reduced take-off height, which is again particularly beneficial when treating items with large elastic fibre content.
The new Thies soft-TRD SIII is suitable for a wide range of textiles including multi-filament textiles, high-density products, mixed fabrics with varying elastane and polyester contents.
In addition, high-quality woollen items can also be treated and the treated woven and knitted fabrics as well as non-woven textiles are characterised by their soft, voluminous feel.
