    Abstract: An elastic covered yarn the core of which is a wrapped yarn consisting of elasthan filament yarn having polyamide, polyester or viscose filament yarn as the sheath material, and which may be covered with different materials. This yarn has advantages in its properties and in processing compared to those covered yarns, the core of which is a bare elasthan filament yarn.

    Abstract: This invention relates to melt extruded latent contractable elastic filaments which are formed by melt extruding certain segmented crosslinked thermoplastic polymers to form filaments, which filaments, when heat processed at elevated temperatures, significantly contract to yield an elastic filament. This invention also relates to the formation of composite covered yarn comprising said latent contractable melt extruded filaments. In addition, this invention relates to processes for forming articles from said latent contractable filaments or covered yarns comprising said contractable filaments and subsequently contracting said yarns to form an elastic article.

    Abstract: The present invention relates to a method of making a covered elastic yarn with an elastic thread as a core yarn, and a continuous thermoplastic multifilament thread as a sheath yarn, wherein the respective filaments forming said covered elastic yarn are respectively tangled with each other to retain flux form, and at the same time to form the sheath-core system, and said sheath yarn wraps the outer periphery of said core yarn but is reversed irregularly and intermittently in said direction, and said sheath yarn and said core yarn are substantially twistless.

    Abstract: An ornamental expansible strip for use as a yarn stretch gift packages tie and as a decorator hair tie, and the method of making the same. The expansible strip comprises an elastic core under a retained low stretch and an ornamental yarn cover embracing the same, the yarn cover comprising yarn strands which are stretched and coiled about in the same direction and on opposite side of the elastic core, the core and yarn cover combinedly possessing a stable twist, the yarn being tightly wound, and locked to the stretched and twisted elastic core.

    Abstract: This invention concerns with a process for the preparation of a yarn package which comprises a plurality of polyurethane elastic yarns wound up on a single bobbin. The yarns are arranged substantially in a plane when seen laterally of the yarn group and provisionally bonded together for providing the possibility of re-separation into the constituent yarns at a later rewinding stage of the package. According to the invention, a plurality of groups of multifilaments comprising essentially polyurethane as extruded are passed through a corresponding number of false twisters, so as to group the respective filaments together to such a degree that the related filaments are partially fused together to set a mutual core-to-core material communication, yet having a solidified surface skin except the thus realized material communication areas on the filaments. Then, at least two of the yarns of multifilaments are jointly passed through a skew-grooved traverse for provisionally bonding these yarns together so as to realise a skin-to-skin co-bonding, for ready for winding into a yarn package on a single bobbin tube.
