Hi all,
I started using Blender some months ago and i am very Happy About this huge Community. I was looking for a way to get a realistic Render of Cotton objects Like this one:
Thank you
Check out this (free) procedural shader created by simon thommes!
You can use Adaptive Subdivison along with displacement. This way you can keep your original polygon count and enable displacement only when close-up. Here’s a quick render.
you might just need to use microdisplacment
Thank you all for your replys!
I think i try the Workflow of @ibotpl first because i allways want to understand the Base modeling and shading techniques before i use external shaders 
But after that i will try all to find my best Workflow and show you the results.
@ibotpl i would be very Happy when you can send ne your blend File or the textures you used because i want to reproduce your quick render.
Am i right that the difference between displacement and microdisplacement ist the Polygon amount?
yes
displacement need a huge amount of physical polygon ,
the more ther is polygon, the more details youll have
micro-displacement however dose not need physical polygon , and only whene needed
however the micro-displacement has some downers ,
like partical system dosnt work with the micro-displacement surface, it ignore it like its not even there .
Thank you! Ich will respond with my results
From which material are female sports shorts and cuffless t-shirts you know for athletic women and for those women who are playing basketball in real-life? With which material Disney’s princesses got rendered her dresses in Pixar’s Ralph Breaks the Internet? With which material sports clothes could be Lola Bunny,Lori Jackrabbit and Tiara the Manx if these characters might be rendered as well?
