Wound cop conditioning
For the conditioning of yarn wound into cops, at a ring spinner or twister, after the yarn is wound round the sleeve an additional fluid is applied to the wound yarn according to a set program, before the sound cops are transferred to a conditioning appts. Also claimed is a winding sleeve with openings for fluid to pass through. Pref. during conditioning, the wound yarn at the start is heated to a temp. within a given temp. interval. The additional fluid applied to the wound yarn has a chemical quality which, before and during and/or after conditioning improves the yarn character. The fluid is applied pref. to the outer surface of the wound yarn, to penetrate through the windings and the openings in the winding sleeve, through an underpressure at the fluid outlet side. The additional fluid is pref. sprayed on the outer surface of the wound cops.
