Abstract
Process for the manufacture of a core and envelope yarn whose yarn forming the envelope surrounds the core yarn alternately in the s direction and in the z direction, characterized in that together with the core yarn subjected to a false frictional torsion it is introduced together with the in the false twist installation an envelope yarn with a supply speed in excess of at least 10% laterally, forming an angle of at least about 15º with the core yarn, and both yarns are conducted in common on the friction surface that generates the false twist, moved essentially perpendicular to the general direction of movement of the yarn, the frictional contact of the yarn with the friction surface being briefly severely diminished at very short time intervals, unless approximately 50% of the normal value, and eventually up to zero.
