ABSTRACT:
A milk filter sock composed of a folded sheet of spun bonded, randomly oriented, continuous, synthetic fibers. The longitudinal edges of the sheet are joined together by an ultrasonic bond, and one pair of end edges of the folded sheet are also joined by an ultrasonic bond to form an open-end tubular sock. The spun bonded fibrous material provides increased strength for the sock and more uniform filtering characteristics. In addition, the filter sock has less weight and bulk than prior art filter socks.
