Activities in the textile industry include
a wide variety of processes and techniques for transforming natural
and synthetic materials like wool, cotton and nylon into useful
and aesthetically pleasing cloth products. Wool dyeing is one of
these important processes but manufacturers have long struggled
to find an efficient dyeing method which does not cause yellowing.
This project concerned the development
of new processes for bleaching, pastel dyeing and drying of wool
or wool blends without yellowing. New bleach enzymes and post-treatment
processes were developed, as well as a new and innovative dryer
using both hot air and high-frequency radio waves, a combination
never before seen in the wool processing sector. These new developments
allow more flexible and continuous production, 24 hours a day.
The feasibility of the new dyeing method
has already been demonstrated under workshop conditions. Prime partner
Madeleine, a dryer manufacturer, sees other potential applications
for its new technology in the food, stainless steel and carpet manufacturing
sectors and expects a large increase in its annual turnover as a
result of the project.
