Save them as an OBJ and you can import them into Daz. I don't know how to bring textures in other than applying them in the surface tab individually though.
I never used 3DMax (I am an ex-Blender guy) but you need to define surfaces and assign textures to them or the OBJ prop will have just a single surface when you import it to DAZ.
Of course you can define the surfaces in the Das itself using the Geometry editor tool but I don't know how to make UV map in Daz and in this case you can only assign seemless textures (or just colors) to them or they may become distorted.
Hope this helps.
