A method for cleaning fiber in a cleaning machine comprising deliberately applying during removal of particulate matter a gas flow conditioned as to a parameter selected from the group consisting of humidity, temperature, pressure, gas composition, free charge concentration, static charge, radioactive particle concentration, velocity and pressure fluctuations.
- 2. A method for cleaning fiber in a cleaning machine comprising deliberately applying in preparation for removal of particulate matter a gas flow conditioned as to a parameter selected from the group consisting of humidity, temperature, pressure, gas composition, free charge concentration, static charge, radioactive particle concentration, velocity and pressure fluctuations.
- 3. A method for processing fiber in a machine comprising deliberately applying during processing a gas flow conditioned as to a parameter selected from the group consisting of humidity, temperature, pressure, gas composition, free charge concentration, static charge, radioactive particle concentration, velocity and pressure fluctuations.
- 4. A method for processing fiber in a machine comprising deliberately applying in preparation for processing a gas flow conditioned as to a parameter selected from the group consisting of humidity, temperature, pressure, gas composition, free charge concentration, static charge, radioactive particle concentration, velocity and pressure fluctuations.
- 5. A method for treating fiber for release and separation of foreign matter from the fiber comprising transporting the fiber to a treating station and subjecting the fiber at the treating station to a combination of aeromechanical forces to achieve controlled release and separation of foreign matter in particle sizes of predetermined classifications while applying a gas flow conditioned as to a parameter selected from the group consisting of humidity, temperature, pressure, gas composition, free charge concentration, static charge, radioactive particle concentration, velocity and pressure fluctuation.
- 6. A method in accordance with claim 5 which comprises transporting the fiber including foreign matter to a region proximal to a surface having perforations through which conditioned gas flow is drawn such that the foreign matter is separated into predetermined classifications according to passage or nonpassage through the perforations.
- 7. A method for treating fiber for release and separation of foreign matter from the fiber comprising transporting the fiber in a transport gas flow to a treating station and subjecting the fiber at the treating station to a combination of aeromechanical forces to achieve controlled release and separation of foreign matter in particle sizes of predetermined classifications, the transport gas flow being conditioned as to a parameter selected from the group consisting of humidity, temperature, pressure, gas composition, free charge concentration, static charge, radioactive particle concentration, velocity and pressure fluctuation.
- 8. A method in accordance with claim 7 which comprises transporting the fiber including foreign matter in a conditioned transport gas flow to a region proximal to a surface having perforations through which transport gas flow is drawn such that the foreign matter is separated into predetermined classifications according to passage or nonpassage through the perforations.
- 9. A method in accordance with claim 7 which comprises separating the foreign matter and fiber by application of aeromechanical hook forces to the fiber employing a combination of moving and stationary projections.
- 10. A method in accordance with claim 7 which comprises subjecting the fiber to carding action at the treating station.
- 11. A method for treating fiber for release and separation of foreign matter from the fiber, comprising:
- providing a treating element for imparting aeromechanical forces to the fiber including foreign matter for releasing the foreign matter from the fiber which forces tend to throw at least foreign matter particles outwardly from the treating element; and
- causing a gas flow towards the treating element in a direction counter to the direction of particles thrown outwardly from the treating element so as to achieve controlled separation of foreign matter in particle sizes of predetermined aerodynamic classifications, the gas flow being conditioned as to a parameter selected from the group consisting of humidity, temperature, pressure, gas composition, free charge concentration, static charge, radioactive particle concentration, velocity and pressure fluctuations.
- 12. A method in accordance with claim 5, which comprises separating the foreign matter and fiber by application of aeromechanical hook forces to the fiber employing a combination of moving and stationary projections.
- 13. A method in accordance with claim 5, which comprises subjecting the fiber to carding action at the treating station.
