Pressure to reduce pollution while staying competitive

Second only to agriculture, the tex-tile industry is the heaviest industrial consumer of water as well as being one of its biggest polluters. In recent years, there has been increased pressure on the textile industry from governments, NGOs and consumers to do a better job of protecting the environment.

For many years, the textile industry has tried to identify new ways of reducing water consumption. Taking a pragmatic

view, industry insiders realize that the widespread adoption of costly solutions such as waterless dyeing is years away. The dye industry is typically low-mar-gin and necessary new machines are expensive.

How to go about sustainabletextile production

Pragmatic, feasible and cost-friendlysolutions are needed to quickly address the current environmental problem. Solutions like the eco-friendly and efficient HeiQ Clean Tech technology

help mills to considerably reduce their environmental footprint while at the same time allowing them to use their existing equipment.

Case study at Turkish mill

HeiQ Clean Tech's potential for water, energy and time consumption savings was tested at a textile mill in Turkey in January 2016.

The total dye time of polyester was reduced from 3 h 50 min to 2 h 38 min (31% reduction). Thanks to HeiQ Clean Tech the water consumption was reduced from 2,700 to 1,800 liters (33% reduction). Nine liters of water were saved per kilogram of fabric, which amounts to yearly water savings of 3.4 million liters of water per dye jet. The time savings reduced the total usage of steam (oil heating) from 255 m3 to 101 m3 (60% reduction). Total usage of electricity (coal generated) was reduced from 96 kW to 66 kW (31% reduction). CO2 emissions for steam and electricity where reduced by 76 kg (31% reduction), which amounts to 2,700 tons saved annually for one dye jet. The total cost of dye for 1 kg of polyester was reduced by 5% (including the dyestuffs) and 25% (excluding the dyestuffs). This corresponds to annual savings of USD 35,000 for each dye jet at the mill.
