Abstract: A system and method for providing conditioned air to a yarn traveling on a textile machine includes an air conditioning unit local to said textile machine and configured to receive input air and to condition the air to a first desired relative humidity. An air delivery conduit is in communication with the air conditioning unit and conveys the conditioned air therefrom. A diffuser is in communication with the delivery conduit so that the conditioned air flows into the diffuser. The diffuser defines a nonuniform opening so that the conditioned air leaves the diffuser in a turbulent flow. The opening is disposed at a predetermined distance from the yarn so that an air mixture, comprising the turbulent conditioned air and ambient air drawn into the turbulent flow, has a second desired relative humidity upon reaching the yarn.

Abstract: An airborne filter system includes an array of drum filters and a frame disposed in a permanent operative position proximate the array. A plurality of longitudinal members are operatively disposed on the frame, each longitudinal member extending into the interior area of a drum filter. A suction nozzle extends from each longitudinal member to operatively communicate with the interior surface area of the drum filter for removing waste material therefrom. A drive mechanism is in operative communication with the longitudinal members to rotate each about its longitudinal axis and to reciprocally move each longitudinal member substantially along the longitudinal axis of the drum filter from which the longitudinal member extends so that a suction end of the suction nozzle is moved substantially over the inner surface of the filter. A suction source is in operative communication with each suction nozzle to apply suction to the suction nozzles so that the waste material is drawn therethrough.
