ABSTRACT Wrapped core yarn made up of a compressable core of fibers arranged to lack tensile strength, and wrapper yarns wrapped in both directions around the core, crossing periodically under enough tension to compress the core. Preferably, the diameter of the core is reduced about 30 to 90% by compression where the wrapper yarns cross. Desirably, the tension on the wrapper yarns gives the core a sinuous configuration extending along its length, and portions of the core protrude outwardly from areas where the wrapper yarns cross over one another. The fibers may be staple fibers substantially free of twist. The fibers may be arranged substantially parallel and may be free of ad- hesion to one another. At least one of the wrapper yarns may be a shrink yarn and the core of non shrink fibers. A method of making the yarn of the characteristics des- cribed.
