that are bonded to one another by an adhesive binder with the adhesive but not the fibers being soluble in the solvent by restricting the length of the fibers the yarn will fall apart when the adhesive binder is removed a particularly preferred yarn comprises fibers e g polyester fibers which are bonded to one another by polyvinyl alcohol the polyvinyl alcohol but not the fibers being soluble in water which is a preferred solvent yarns composed of fibers e g polyester fibers bonded to one another by polyvinyl alcohol are commercially available for use in the manufacture of various consumer products e g high loft towels and thus in addition to the physical and chemical properties that make such yarns well suited for use in the present technology these yarns have the additional advantage that they are already being produced in large quantities and thus are relatively inexpensive when water is the solvent used in the treatment it typically will be employed at an elevated temperature and indeed the water may be entirely or partially in the form of steam at the time of use the water steam can be applied to the yarn at various points in the process e g it can be applied to an intact knitted tube produced by a run of.
