According to aerosol science, whenever liquid hangs in air it is technically an aerosol, but other disciplines use the word “droplet” to mean a coarse particle five micrometers or larger, and reserve “aerosol” for fine particles smaller than five micrometers in effective diameter.

When we breathe, talk, eat, cough, sneeze or sing, we emit particles across a range of sizes, both coarse and fine.  Even though there are gaps between the threads in cloth, the threads are usually wider than the gaps.

THE GAP IS MORE A TUNNEL THAN A WINDOW

 

At a microscopic level, the thread has thickness, or depth, so the gap is more a tunnel than a window. Microfilaments from broken or irregular threads project into the gap. Particles are not like a mosquito, which can redirect itself to avoid obstacles. A particle with momentum will run into a fibre, even though the air stream is diverted around it, like a ball hitting a wall — this is called impaction.

But at the microscopic level, there are two additional processes in play. Particles also fall out of the air — called sedimentation. Some particles are moving randomly and this random motion brings them into contact with fibres — called diffusion. Finally, cloth can be used in multiple layers, adding a second and third gauntlet for the particle to run before it reaches the other side.

Multiple washing only increases the effectiveness of a cloth mask.
