Abstract: A process is disclosed for preparing slubby strands in which a textile strand is passed either over a surface or through a slubbing tool. The surface, if employed, may include a plurality of fluid passages positioned therein. As the strand passes over the surface or through the slubbing tool, high pressure fluid is introduced onto the surface of and through the strand. The high pressure fluid passes through the strand.

When a surface is employed, the surface may be a moving surface and when the surface includes a plurality of fluid passages, the passages may be vented at a point below the surface. Various apparatus for carrying out the novel method are disclosed as is the novel strand produced thereby.
