摘要： A fasciated yarn suitable for making apparel fabric and having properties approaching that of ring spun yarn is produced by vacuum spinning, including directly from sliver. An elongate hollow shaft (20) of the vacuum spinning apparatus has a vacuum reservoir (32), or interior chamber, that is generally in the shape of a right circular cone, and the interior passageway (31) of the shaft from the first end (21) thereof to the interior chamber can have the form of a right circular cone frustum. Perforations (40) operatively connected to the interior chamber have a generally wedge-shape. The perforations and the passageway sections between the first end of the shaft and the perforations are dimensioned so that they allow sufficient air flow to achieve optimum fiber wrapping action. Initial threading of the vacuum spinning apparatus is provided by a vacuum tube (745) mounted for rotation about an axis parallel to and spaced from the axis of rotation of the shaft, the vacuum tube being connected up to a vacuum reservoir (742) and source of vacuum (728) and rotatable from an inoperative to an operative position.
