High Tech Solutions for Dyeworks Sustainability
Our dye works uses state-of-the-art technology that oxidises 100% of the organic
dyestuffs in the used dye liquor. This turns them back into their derived elements,
producing water that is completely clear and a small amount of hydrogen. There is
no resultant slurry to dispose of and no reduction of efficiency as filters become
clogged towards their end of life. The clear water is then ideally suited to be
reprocessed and recycled via the municipal waste water system.
Sudbury Silk Mills was one of the very first textile manufacturers to utilise this
technology and we are always looking to make sure that we are on top of new
developments and solutions to improve sustainability.
The combined knowledge and expertise of our skilled staff
contribute to our ‘right first-time’ initiatives throughout our design
and manufacturing processes; minimising waste, reworking of
materials and energy consumption through product development,
yarn dyeing, weaving and finishing.
Ultra-efficient pressurised cone-dyeing reduces the amount of water and
dyestuffs required in the dyeing process. All dyestuffs are REACH compliant and
entirely Azo-free. The heat from the dye liquor is recovered in a heat exchanger to
preheat water for subsequent dyeings, which in turn cools the waste liquor to the
temperature required for treatment.
