Electric Resistance Heaters
Electric resistance heaters are used for heating the glue applied over the print blankets, which holds the fabric in place. When the belt finishes its movement on the upper side and when it moves down, the glue gets dried, which has to be heated again to retain its properties before it is exposed to the fabric again. In place of electric heaters if infra-red heaters are used, the efficiency would be better and energy consumption will be reduced.
Reduced electricity consumption of about 4 kWh/hour per infra-red heater.
Better work environment.
This option of Electric Resistance Heaters is a technology modification option for heating of the print blankets on continuous printing machines. This is a measure applicable to all printing machines that use print blankets (endless), which are coated with adhesives for holding the cloth in place while printing.
Investment cost per infra-red heater is Circuit Maintenance Process . Thus, annual savings are calculated to be INR 86 400 (USD 1 920) for operation of one infra-red heater, replacing three electric resistance heaters. Payback period is less than a month.
Pentachlorophenol by di-chlorophenol
Di-chlorophenol is less toxic than pentachlorophenol and can serve the purpose of a print paste preservative (used also as size preservative) and hence could be used in place of penta-chlorophenol. The measure would result in toxicity reduction.
Next to the working time of the employees involved in the project and installation of the instructions, no extra costs are associated with this measure.
Experience demonstrates a fast pay-back, due to adequate chemical handling by employees, accident prevention and appropriate waste management.
Reduced toxicity. Reduced fire hazards. Microbial growth in effluent treatment plant is not disturbed due avoidance of toxicity.
Applicable in the print paste preparation section of the textile printing industries.
Investment is same (because, it is just replacement of input material). Annual savings in monetary terms is negligible, but there are great environmental benefits along with the operational ease of the effluent treatment plant.
