People in textiles-producing countries are now aware of the deteriorating water quality and the lack of sufficient clean water for homes and agriculture is in threat. The garments buying developed countries are beginning to demand Eco-friendly garments and textile products.
This changed demand is putting pressure on brands and retailers to show that their supply chains are clean and transparent. Governments too have reacted by mandating more rigorous environmental legislation and by more strictly enforcing their pollution laws.
Like Bangladesh, the textile industry is the backbone of many developing economies. It is also heavily reliant on water. New technologies and simple fixes may help mills remain competitive while reducing water use and contributing to a green environment.
It is unexpected, a new cotton T-shirt is required approximately 2,650 litres of water to grow, produce and transport. In using conventional methods, an extensive proportion of 20 percent water usage and more- is used in just the phase of dye. Up to 100 litres of fresh water and very high amount of energy is required to dye just one kilogram of cotton fabric.
Much of this water is polluted by the salt used for absorption of the dye. This salty wastewater is harmfully consumed or used for irrigation, and it is unsafe to aquatic life.
These long going has caused deteriorating in regions facing acute water scarcity. Unfortunately, many of the world’s largest textile-producing nations like China, India, Bangladesh, and Brazil are also those most vulnerable to water shortages. Even so, the United Nations is warning that half the global population could be facing water shortages by 2030.
Taken together, all of these factors make reducing our use of water one of the most pressing challenges facing the textile industry.
After several years passing under development, the water less dyeing technology has already produced sustainable products by using recyclable carbon dioxide (super-critical CO2) as the application medium to infuse colour into the fabric instead of water. This comprehensively reduced the use of water in the textile dyeing process and would benefit the industry in years to come.
This inventive development may help mills make dramatic savings without requiring substantial investment in new plant or equipment. These new innovations are a range of reactive dyes for cotton and cellulosic fibres using technology, using less salt during dyeing and less water during the wash-off process.
The conventional dye house technologies, which many mills in developing nations may potentially save more than 820 billion litres of water per year using this new and exciting technology.
Changing the mindset of textile millers about water conservation will need to be an industry priority.
