Process Chemicals auxiliaries set the color tone – Dyeing
Colors change as quick as fashion. But their brilliance and fastness must never change. Besides the right dyes, the optimum dyeing auxiliaries are paramount. No need for our customers to experiment; we have done that for them.
The process requirements in dyeing are countless. Starting from the three basic principles – i.e. the dye either reacts with the fiber, penetrates it or adheres to its surface – the spectrum splits into a multitude of individual processes. Practically every fiber – polyester, polyamide, polypropylene, polyacrylonitrile, viscose, cotton, linen, ramie, wool, cashmere, camel, and lama hair – needs its own, self-contained dye system. There are hardly any overlaps, and even these yield poor results. So each dyeing process needs its own systematic combination of chemicals with differently adjusted parameters such as pH, temperature profile, and time. And that is not all: Depending on the fiber grade, the various and fundamentally different processes – for cross-wound, knitted or woven goods – also require completely different machinery.
Competence in all fiber grades and machine technologies
Pulcra Chemicals offers the appropriate system for each dyeing process, tuned to your specific machine technology – for trouble-free processing and brilliant, colorfast results. Our competence is a key success factor in quality and efficiency equation. With sound advice and solution-oriented service, we help to obtain results that will meet market needs and improve the efficiency and quality of our customers’ processes, and hence your competitiveness.
Taking the froth out of polyester dyeing
In polyester dyeing, foam-free operation in advanced equipment is still a challenge for any dyer. With special products like Breviol® from Pulcra Chemicals, all add-ons become feasible with all types of machines. Our Lamepon® assures perfect control in dispersing dyes. The result: Maximum uniformity of dyeing, no problems with oligomers, greater efficiency through less need for redyeing.
Elastane without streaks
When dyeing elastane fiber mixes, Breviol® helps to achieve streak-free, even results without damaging the fibers. Our running crease inhibitors do an excellent job in all machines and on all types of fiber. With Breviol®, our customers can run even sensitive fabrics trouble-free on winch backs or jets, without restricting the action of other chemicals in the dye bath.
Stress-free wool coloring
Wool is a particularly tricky fiber to dye. High temperatures and the use of acids in wool dyeing normally result in wool weight loss due to leaching out of proteins. The wool loses its luster, its natural character, its stability, and elasticity. Problems like these are now past history: With protein products like our wool protecting agent Breviol® WSM, our customers can restore lost proteins and prevent quality losses.
Your benefits:
- Dyeing auxiliaries for trouble-free operation and colorfast results
- Competence in all fiber qualities and machine technologies
- Tailor-made systems for every dyeing process
