I don't know Omo detergent, and I suspect I'm in a different part of the world from you. I'd expect this to be caused by detergent that's not rinsing out of the towels correctly because you're using too much detergent for the machine, or the water is quite hard and calcium in the water is causing poor rinsing.
Can you get washing soda (sodium carbonate) or one of the dry "water softener" additives with sodium sesquicarbonate? If so, I'd try washing a load of towels several times with no detergent, but with washing soda, and then comparing the texture of the rewashed towels to a towel that you've saved out for purposes of comparison.
I suspect you'll find that you have washed out enough detergent residue that the towels have softened considerably. If so, find out the chemical hardness of your water (in the US, hardness is measured in grains or parts per million (ppm)) and then consult with the detergent manufacturer as to the correct amount to use for your machine and water hardness.
too much chemistry.
