The textile backward linkage factories are facing the two most hectic challenges, such as dealing with the increased cost of utilities and energy shortages while also meeting buyers' demands for reduced CO2 emissions. The low-temperature dyeing methods that minimize liquor ratios, shorten dyeing times, and maximize steam utilization are needed to address all of these issues.
</br>
The textile dyeing process stands out as a significant contributor to the carbon footprint of the textile & apparel industry. Dyeing fabric is a demanding process that uses a lot of energy and water. Just to colour 1 kilogram of grey fabric, it takes 2-3 kilograms of steam every hour. Typically, dyeing requires high temperatures for a long time, leading to a large amount of steam being produced from fossil fuels, which releases CO2 into the air.
</br>
Hence, the textile industry uses a lot of energy, which makes it costly to run. Energy alone can make up about 20% to 30% of all the money spent on making things, coming right after the cost of the materials used. Recently, gas prices have shot up, making things even tougher for Bangladeshi textile factories. Their gas bills have tripled, and on top of that, other fuels like diesel have gotten more expensive too, shrinking the amount of money they make. With labour costs also going up, factories have no choice but to find ways to spend less money.
</br>
Moreover, the low pressure of gas causes the industry to production loss and reprocessing of dyed fabric. According to the report of Bangladesh Textile Mills Association (BTMA),
“The country’s export-oriented textile sector has incurred production loss worth $1.75 billion owing to the lack of enough natural gas supply to the factories”
During this time when energy is scarce, clothing brands are telling factories to emit less CO2. The textile industry is estimated to be responsible for a staggering 10% of global emissions, making it the second largest polluter after oil, and the dyeing process stands as a significant contributor. The buyers are committed to reducing carbon emissions; they're closely watching how much CO2 factories let out.
Mohammad Reaz Uddin, a senior manager at HAMS Garments, says, “Brands are really pushing factories to emit less CO2. For example, H&M wants to cut their greenhouse gas emissions by a big amount—56% less by 2030 compared to 2019. And by 2040, they want to have zero CO2 emissions. This means they want to reduce emissions by 90% and use methods to take carbon out of the air. Other brands are also trying to emit less CO2. So, it's really important for our industry to do better because brands will keep pushing us.”

Nazrul Amin, another senior manager at HAMS Garments, says that by using a low-temperature dyeing method, we can save a lot of money and emit less CO2. This method is especially helpful for knit dyeing, which usually needs high temperatures.
</br>
Since the dyeing process uses a lot of energy and water, which adds to the industry's carbon footprint, if we start using low-temperature dyeing techniques, we can emit less CO2 and spend less on utilities by using less steam, making a big difference in reducing our industry's carbon footprint and making the world a cleaner, greener place.
