What do you think ?

Yet, if you look well, I have what looks like air bubbles stuck close to the cloth. Not many, but still. What could I do to really get rid of them ? During the infusion, I wait a "long" time before closing the vacuum line (to evacuate the air contaminated resin). By "long" I mean I wait until the resin reaches the catch pot and that some of it flow into. I clamp the vac line but I can still see some bubbles coming from the output of infusing part, inside the hose.
