Abstract
A yarn wetting apparatus, especially for a two-for-one twisting spindle assembly, and a two-for-one twisting spindle assembly having a yarn wetting apparatus disposed on the upper end of its spindle hollow axis, are provided. The yarn wetting apparatus comprises a reservoir, a porous wetting body which extends to the reservoir and has a capillary capacity, and a yarn passage opening which tapers in the direction of the spindle hollow axis of the two-for-one twisting spindle assembly, wherein the inner end of the yarn passage opening is in communication with the reservoir via at least one wetting agent back flow channel.
