Separation processes of particles from a solids-laden gas stream on a polymer fiber were visualized by Friedrich Löffler and Heinz Umhauer in 1971. One can see:

• Separation (e.g. from min. 2:42)
• Electrostatic effects (from min. 3:45)
• Bouncing off (from min. 5:00)
• Reduced bouncing through applying adhesive (from min. 6:00)
