Thanks both for helping me. I have done a bit of research, so hopefully I can bring more information to achieve the desired material.
First I need to say I do not have substance so I am relaying on already made textures. I am using Quixel Megascans and I am using a surface imperfection for concrete:
I also have found that poliigon has a really nice material, but I do not have the membership. But I believe it helps to show it.
This is my first attempt using the glossy material (multi-scatter active):
Some questions about luxcore:
- I tried to increase the contrast between the black and white using the color ramp. I believe this is the way to do it. The only issue I found moving the offset slides is that the black and white starts to expand...I wonder if its possible just to have the map as it is and darken and whiten the areas whitout having the eating each other in areas.
I am not sure if this is the way to do it since I do not see a sheen parameter.

Tryout using Velvet node
I tried adding the image texture into the thickness socket. Look a bit extreme and almost like a dirty floor.
Node here:
Honestly I read in the wiki, but not super sure how thickness works. I understand it gives more fuzziness in some areas than other. Maybe its more about understanding how to tweak the black and white values of my image texture.
Here I tried with the thickness socket value .25 , looks better. I also noticed that changing the thickness parameter changes drastically the wood look...guess it has to do with the reflectance caused by the velvet floor

I also found a tutorial in youtube showing a really convincing velvet material in cycles with a rather simple node. I understand he is cranking the principle sheen parameter, something already discussed in the post previously by other users.

I can not find a rate take on his video where I can visualise the whole node setup, so I will explain it :
He uses a roughness map>colorramp>math(multiply by 8) to the seen socket. Then he mixes a normal map with folds with a voronoi (super small to create the short hair look) in the bump socket and his work looks like this:
I am recreating it in luxcore:
-------------------------------
I think between glossy, velvet and the disney alternatives...the most convincing is velvet with the thickness socket without a texture...The only think I am not super happy with is the wood darkening ....but I guess I can photoshop that.
Now I will try to see what happens by adding a bump of a really small noise.
