APS Group started a new era in the exhaust dyeing process by saving a huge amount of water consistently from 2014. Hasib Uddin, Chairman of APS Apparels (Dyeing Unit) Ltd. played the pioneering role in the whole journey of this water-saving activity.
APS Apparels (Dyeing Unit) Ltd. was established in 2009 and is committed to achieving highest customer satisfaction by ensuring the social compliance and the legal requirement for all facilitates. From the beginning Hasib Uddin leading from the front line to a bigger change of the industry. Let’s hear the story in his words.
Once we had a severe problem of water in the dyeing unit due to some unavoidable technical problems. Fortunately, at that time, I went to Germany, Switzerland, and Turkey to attend some training programs. Surprisingly I found they are dyeing fabric through the exhaust process by using a very little amount of water. “If they can do such amazing thing then why can’t we?” this question thrust me much to do this kind of activity. This is true that we had urgency but importantly we need the mindset to be changed. What I see that in our industry lots of people have that knowledge and potentiality but they do not want to be changed or they just fear to be changed!
I think any dye house of Bangladesh which even have 10-15 years old machine can easily dye the fabric through exhaust dyeing process by consuming maximum 35 liters water for per kg fabric.
So, we did dyeing our first batch of fabric successfully by lowering the water to only 33 liters per Kg. The next day again we dyed two batches which were also successful and finally, we decided to start dyeing in all of our machines by following a similar process. But within a few days, we experienced a quality problem in a batch. We assessed our dye line and tracked down the problem which leads us to develop a data bank which you can consider as the great asset! From 2012 we started to develop our data bank and now we easily can dye any kind of fabric within 15.38 liters to 33 liters for per kg fabric which really a success for us.
Eventually, the databank will help you to maintain the quality consistency and I recommend all the dye houses to develop such data bank.
Here in our new generation machine, we only use 16 to 23 liters of water for per kg fabric and it could be any kind of color and fabric. In our conventional machine which has 1:5~10 liquor ratio depending on the loading capacity, we generally use 33 liters and maximum 35 liters of water for per kg fabric. processing inside the machine.
So, I think any dye house of Bangladesh which even have 10-15 years old machine can easily dye the fabric through exhaust dyeing process by consuming maximum 35 liters water for per kg fabric. Just need to change their mind to launch the process.
