Save water when dyeing with Fongs technology
Mar '10
In 1992, the United Nations General Assembly designated 22nd March as “World Water Day”. Every year on that date, people worldwide participate in events and programs to raise public awareness about the critical lack of clean and safe drinking water supplies—and to promote the conservation and development of global water resources.

The textile industry consumes huge volume of water everyday and the dyeing industry is undoubtedly one of the industrial sectors that threatens the safety of drinking water. In an effort to save the precious water resource and reduce the environmental impact, Fong's Industries Group along with its member companies, namely “Fong's National”, “THEN”, “Goller” and “Fong's Water Technology” provide an ecological dyeing solution to reduce the water consumption drastically through their innovative technologies covering the processes from yarn dyeing to piece dyeing and recycling of discharge after dyeing and finishing.

1.Yarn Dyeing Process – Fong's ALLWIN High Temperature Package Dyeing Machine:
Yarn dyeing is nothing more than imparting colour to the yarn that will soon be used in knitting or weaving projects, however, it consumes an enormous quantity of water and electricity at the dye houses, which impels the industrial manufacturers to find an environmental solution to revitalize their competitiveness.

Fong's ALLWIN High Temperature Package Dyeing Machine offers an unprecedented liquor ratio as low as 1:4 with its integrated design of REV centrifugal pump, heat exchanger and the flow reversing system (patent granted). The newly designed integrated circulating system results in space saving by approx. 25% as compared with conventional machine arrangements.

With the capacity ranging from 28 kg to 9129 kg, ALLWIN is equipped with AIR+ Advanced Intelligent Rinsing System, which shortens the processing time for cotton yarn to 276 minutes, the total water and electricity consumption for dyeing medium to dark shade yarns are reduced to 34l/kg and 0.43kWh/kg respectively, consequently a significant saving on water and electricity consumption by over 40% and chemical cost by 19% as compared with conventional machines.

The ILC Intelligent Levelling Control System monitors the water flow through the package from outside-in to inside-out and vice versa. The ILC improves the levelling of colour through out the whole package thereby reduces yarn loss and increases reproducibility from batch to batch. The outstanding performances of these features save total production cost by 30%, making it a premium choice for yarn dyeing facilities everywhere.

2. Discontinuous Dyeing Processing – Overflow and Airflow Dyeing Machines:

Despite the new technologies being introduced to the industry over the past 2 decades, the overflow dyeing machines are still being widely used in the knitted fabrics segment nowadays. Fong's National has constantly endeavored on the product development and research to meet the great demand from the customers for eco-friendly dyeing machines with low water and energy consumption to face the rising competition in the textile sector.
