Abstract: Method for controlling a full automatic washing machine, the method comprising a washing cycle, a rinsing cycle, and a dewatering cycle, wherein the washing or the rinsing cycle includes the step of rotating an inner tub at a high speed higher than a preset speed in one direction, thereby making a centrifugal force caused by high speed rotation of the inner tub, to push laundry against a wall of the inner tub, to enforce washing water in the inner tub to penetrate through the laundry at a speed higher than required to make the wing done, and to pump the washing water penetrated through the laundry and discharged into an outer tub upward, to recirculate to the inner tub.

Abstract: An arrangement for transporting yarn through a heat setting chamber has a rotatably driven central mast which is equipped with transport belts arranged around the mast in the form of a polygon in cross section. At least one yarn is wound around the transport belts in loops by means of a winding flyer. At the latest when arriving at the heat setting chamber, the loops should have a larger circumference than the polygon formed by the transport belts for the purpose of forming a shrinkage reserve. This is achieved in that auxiliary belts, ending upstream of the heat setting chamber, are arranged in the area of the winding flyer, the speed of which auxiliary belts corresponds to the speed of the transport belts and which enlarge the polygon to the amount of the desired shrinkage reserve.

Abstract: A soiled piece of fabric is cleaned by mechanical agitation while the fabric is simultaneously subjected to acoustic energy in a gaseous environment wherein the piece of fabric is not immersed in a liquid cleaning medium. Mechanical agitation may be by gas jet action and/or by tumbling. The acoustic energy vibrates the fibers of the fabric to enhance the cleaning action. The piece of fabric may be chemically treated to mobilize the soil.
