Abstract: Apparatus for moistening and texturing yarns is described wherein yarns travel side-by-side over a surface into which bores, one for each yarn, open. Water under low pressure is delivered through the bores, the diameters of which are so adapted to the titers of the yarns that the yarns travelling over the bores exert a suction effect on the water and carry the water between the filaments in each yarn, without any additional layer of water enclosing the yarn, to a texturing nozzle. While passing through the nozzle loops or convolutions are formed in the individual filaments of the yarns by compressed air blown into a whirling chamber in the nozzle. The air is discharged from the nozzle, carrying the water away with it at the same end as the textured yarn, now substantially dry and formed from the non-textured yarns, emerges from the nozzle.
