Abstract: A threaded fastener is made of a composite material made of layers extending parallel to the fastener axis and having elongated filament fibers. A portion of the fibers extend parallel to the axis of the fastener to provide tensile and shear strength to the fastener, and a portion of the fibers extend parallel to the load-bearing thread faces to enhance tensile strength to the threads.

Abstract: Yarn is wound back and forth around a given axis to form a tightly wound package, whereupon dye is fed into the bottom of the package, with the axis thereof vertically arranged, and forced to flow radially outwardly through the bottom turns of the package to take up the dye and color at least the lower end of the package. Alternatively, water will first be similarly fed through the package adjacent the bottom thereof, the wicking action of the yarn carrying the water to a level above the top level to which dye is then fed through the yarn in the manner stated. The wicking action of the water prevents the application of the dye from extending above the top level at which the dye is supplied to the package, thus giving a sharp color cut off, whereas with the unwatered package, the application of the dye is such that the wicking action carries the dye to a higher point, the intensity of the color progressively diminishing upwardly.
