materials used during a survey THere is a list including microscope, magnification etc. The first part has this. I thought it might be some sort of protrective body covering when doing micro stuff.

The strange thing is "diametro" ... can you post a sentence, or at least the real context, if it refers to lab, walls, or anything else that might give a hint?<br>"Apron" could be OK , but I con't see "diameter" when it refers to a "cloth apron"! Cloth doesn't have a diameter!!<br>It must refer to some kind of coating or similar things perhaps, hence not made of cloth at all, in my opinion.
