To use Carbon Cloth Stress as an example.
To export stress attributes onto the Cloth output mesh, tick the corresponding tickbox on the Carbon Cloth node.
For example Bend Stress as seen below:

To visualize this, go to the Maya menu bar and select "Modify->Paint Attributes Tool".
Select the output mesh in the viewport or Outliner and pick the corresponding attribute (e.g. bendStress) in the Paint Attributes section.
Attributes can only be visualized this way, if they are paintable.
More for information:

Next, tick "Color feedback" in the Tool Settings and set "Min color" and "Max color".
Keep in mind: Stress is signed, i.e. there are also negative values
There is not default range for stress, so you have to test a few values before you end up with a good visualization. The example above uses 0.0 for Min color and 0.00001 for Max color.

Stress can be used for a variety of advanced applications.
Here is a small list of the most common ones:
Unlike other cloth sims, Carbon has stretch limits and so stress allows you to check if a garment fits nicely, for example, if there is a lot of stretch stress, the garment might be too small.
You might also use stress data to drive rendering details such as;
wrinkling, or making a dress more translucent where there is a high stretch stress.
If you were using Carbon Tetras for facial sim you might use it to input into skin blood flow (colour) for rendering.
There are so many advanced possibilities
