RESEARCH INTO THE FUNDAMENTAL PARAMETERS OF CONTINUOUS DYEING AND THEIR EFFECT ON SUBSTANTIVITY, MIGRATION AND YIELD OF DYESTUFFS, IN ORDER TO DEVELOP ON-LINE SENSORS AND REAL TIME CONTROL MECHANISMS THAT GIVE CONSISTENCY AND REPEATABILITY

Objective


Partners in this project developed an expert system for continuous dyeing of woven textiles that improves quality and uniformity, reduces the amount of chemicals used, and can reduce the price of finished products by 9.5%.
IN THE FIRST STAGE, FUNDAMENTAL RESEARCH IS TO BE EXECUTED ON FOLLOWING THEMES:
- DRIFT ON THE DYESTUFF CONCENTRATION IN THE PADDER
- INFLUENCE OF TEMPERATURE ON YIELD IN THERMOSOL
- MIGRATION OF DYES DURING IR-PREDRYING
- TEMPERATURE OF POLYESTER IN THERMOSOL
- SHAPE OF BATCH FOR PADDING.

KNOWLEDGE ON THESE RESEARCH THEMES MUST ALLOW FOR AN APPROPRIATE COMPUTER CONTROL SYSTEM FOR THE CONTINUOUS DYEING PROCESS.

IN ORDER TO ACHIEVE THIS GOAL, SENSORS ARE TO BE DESIGNED OR SELECTED, AND TESTED, FOR COLOUR MEASUREMENT, MONITORING AND CONTROL OF RELEVANT PROCESS VARIABLES. SOME OF THE MAIN PROBLEMS IN THIS VIEW ARE THE MEASUREMENT OF THE RELEVANT PARAMETERS IN THE DRYING SECTION OF THE THERMOSOL AND THE REAL-TIME MEASUREMENT OF THE CONCENTRATION OF DYESTUFFS IN THE PADDER.

ALSO, MATHEMATICAL MODELS ARE TO BE FORMED AND TESTED, IN PARTICULAR TO DESCRIBE:
- THE INFLUENCE OF PROCESS-VARIABLES ON THE SHADE OF THE FABRIC- THE INTERACTION OF PROCESS-VARIABLES
- THE BEHAVIOUR OF THE DYE SYSTEM DURING THE START UP PERIOD.
THE SYSTEM ALSO IS TO ADVISE ON THE BEST COURSE OF ACTION WHEN PROCESS PARAMETERS OR SHADE OF THE FABRIC DEVIATE OUTSIDE SET TARGETS. ALL THIS MUST LEAD TO HIGHER QUALITY, INCREASED PRODUCTION AND SAVINGS OF CHEMICALS, WATER AND ENERGY.
